Projecting presentations, images, or videos onto a large display screen for a more interactive and immersive viewing experience is nothing new. Projectors are in use for years now and they have become a necessity, especially in offices, universities, and schools. Their increased affordability has also made them very become popular for home entertainment. Though projectors are highly useful machines, just like any other device, they also experience problems and require fixing. One very commonly experienced problem is incorrect alignment. Although the imaging device on a projector is always square, the projected image may not appear so. This has caused many support calls for projector repair in Houston, most of what could be avoided with proper installation. In this blog, we are addressing a few projector alignment errors and suggesting ways to fix them. For these illustrations, just assume the projector is mounted inverted from the ceiling.

To start adjustments, zoom in or out your image so that it does not fill the screen. To correct a view with a wider top of the screen than the bottom, the projector needs to be pitched down at the front. When the top of the screen is narrower than the bottom, the projector should be adjusted up at the front. This allows you to square the sides. Roll means that the projector isn’t level left to right. To adjust this, make sure your screen and projector are both leveled.

Another common error is called yaw. The projector is leveled to the screen and pitch is accurate but one side is shorter than the other. To fix the problem, the projector would have to be turned to the right or left until the corner comes in line. Going too far would shrink the other side. Again, the edges should be squared. Some compact installation projectors also have length shift capability, which lets users move the image into a specific position. Get your image square as your first priority, then lens-shift the image into position and zoom to fill your screen.

If your projector has four-point keystone adjustments, use them as a last resort. In other words, try everything we just described in this blog before using it.

If you are facing alignment-related problems in your projectors or any other issue and looking for a projector repair shop in Houston, get in touch with us today. Bammel TV specializes in projector and other electronic repairs. We can provide you with an appropriate solution to your problem that is time-effective as well as budget-friendly.

Even if, you have correctly matched your bass guitar amp head and speaker cabinet and set your amp for a clear sound, overpowering or pushing a bass cab past its limits can damage the cab. When you use a rig you are not familiar with, you often overpower the bass cab. This generally happens because we are used to a particular setup and know the limitations of our equipment. Here are some of the problems overpowering can cause in bass guitar speaker cabinets-

  • Audio Distortion – If you usually play with a clean tone, it’s relatively easier for you to figure out if your speakers are getting damaged. The audio is harsh, unpleasant and distorted. The cab might also be broken up if the gain is set high or master is set low or vice versa. Listen carefully to look for warning signs.
  • Weird Noises–When you send too much power to the bass cab, it sometimes causes the speakers to vibrate, buzz, or even pop. When the cab starts making weird noises, you know there is something wrong with it.
  • Loss of definition in the midrange–A lack of definition, especially in the midrange is a common sign of a speaker that’s not performing right. You may also experience increased compression or a sound that seems to be a phase in and out. When anything of this sort happens, you are supposed to turn down the power!
  • Smoke or Fire–Smoke and/or fire are the last things you want to see in your bass amp. Overpowering can lead toa burning smell or smoke coming from an amplifier. Check the voice coil to see if it has melted due to excessive heat. If that’s the case, the damage might have already been done.

Some Tips to Avoid Problems

Using a different amp or backline rig sometimes even blows up the speakers if overpowered. When matching guitar amp heads and speaker cabinets, especially ones that you are not familiar with, please ensure that you have done the homework for it. Don’t forget to check their wattage ratings before running them full throttle.

Using an overdrive pedal or have a dirtier tone can help fix the audio distortion problem to some extent, but only masks the sound, the signs will still be there

3 Maintenance Tips To Avoid Costly Repairs on Your Yamaha Digital Piano

Riddle me this. What has keys but can’t listen to the beauty it unlocks? A piano! Whoever is a piano learner or is an expert at playing it loves the tunes it can produce. The moment your fingers glide onto the keys, you get this inexplicable bliss that is hardly achievable from any other instrument. And if you truly are a music lover, you must have noticed by now that the music lies not in the notes but in the silence between them. It goes without saying that your instrument is utterly close to your heart and you will do anything to keep it unharmed.
If you’re a digital piano owner, there’s good news for you. It requires less maintenance than a standard piano. However, there are still things that you should do to make sure that it doesn’t break down. When it does though, it’s important that you immediately take it to a digital piano repair shop. To avoid such a circumstance, here’s a list of maintenance tips for your piano.

Tips to take care of your digital piano

1. Treat your piano like any other piece of valuable furnishing. Treat it like you would a customary or even a grand piano. A digital piano is inclined to get damaged because of specific components, like heat, water, or even moisture. Abstain from setting the piano close to windows or entryways, as dust and small articles may strike through the window or the open entryways may thump the instrument. Additionally, keep your piano away from the direct rays of the sun. High temperatures can harm the outside surface and the electrical parts.

2. Appropriate cleaning leaves the instrument looking immaculate while inappropriate cleaning can cause damage that is far more awful than the impacts of dust on the instrument. All consoles should be cleaned with a specific goal in mind, so make sure to check your guidance manual for the explicit and adequate cleaning techniques for your specific model. You also should only use a dry cloth while cleaning your instrument as a wet fabric can cause damage to its electrical parts.

3. At the point when your piano isn’t being used, try to turn it off. Leaving the electronic gadget on when not being used can bring superfluous damage to the piano’s segments. Apart from the increase in the life expectancy of the piano, it also helps save money on utility expenses.

What if your Yamaha digital piano needs repair?

Even if following the above-mentioned tips, your digital piano breaks down, it’s important that you contact only an established repair service. Repair of digital pianos, synths, and portable keyboards can present unique challenges, requiring advanced electro-mechanical troubleshooting skills as well as an understanding of the musical problem the musician may be experiencing. Fortunately, Bammel TV Technology Services maintain the technical and musical expertise to deal successfully with the great majority of problems you encounter. We are experts at Yamaha digital piano repair. Get in touch with us now!

Cell Phone Signal Booster Installation Service in Cypress TX

CALL 281-444-0287 to schedule your site survey today! 


Fall 2018

We received call from a previous client, Houston Heavy Machinery, inquiring on possible cell phone signal booster installation service at the customer’s industrial facility located in Cypress, TX. Customer had previously installed a cell signal boosting system but was not getting acceptable results. image 1 of cell phone signal booster installation service job site

First order of business is of course always a Site Survey. Customer’s building was well off the main road, in a quite heavily wooded area. We performed the standard site survey and measured signal strength both indoors and out, using the Surecall cell signal meter. Surecall signal meter used in cell phone signal booster installation serviceAvailable signal levels outside at ground level alone were on the order of -70db across the board—well within acceptable range. Furthermore customer had previously installed a directional antenna and booster but wasn’t getting acceptable results inside the facility. Our plan: use the customer’s directional antenna and pre-run connector cable to power our Surecall Fusion 4Home booster. Surely available signal would be more than adequate, if augmented by a good booster and internal distribution antenna…

We completed installation of system booster amp in the facility attic. Fortunately the peak of Houston’s searing summer heat had passed; even so, attic temperatures were quite warm.


Busted Flat in Bayou City

Standard procedure installation—right? Nope! Strangely,  although the Surecall meter indicated adequate signal levels in the facility offices upon installation, we still had very little available signals on actual phones. Hmmmm…Head scratcher!

Various attempted solutions: all fruitless…Repositioning the internal distribution antenna—useless…We found the local AT&T tower and micro-adjusted customer’s directional antenna—useless. Further small adjustments in view of best generalized/average band-signal levels, made no difference.

In the end the solution proved simple: we went with an omnidirectional internal signal distribution antenna, as opposed to the standard directional distribution antenna. Signal levels jumped notably inside the facility offices. Customer was happy, and we were happy to complete the job.

Another one bites the dust: another successful technology services job at Bammel TV Tech Services. In this case: cell phone signal booster installation service in Cypress, TX, Houston TX, Spring TX, and beyond. For our main page on cell phone signal boost services, click here.

Prophet T8 Synth Repair at Bammel TV Technology Services.

July 2018: Customer brought to us his Sequential Circuits Prophet T8 synthesizer. It’s vintage synth repair time again—in particular, Prophet T8 synth repair time, at Bammel TV Tech Services.

The Prophet T8 , often considered the flagship or pinnacle of the Sequential Circuit line, was released in 1983 when analog synthesizers were being replaced by digital-FM synthesis machines such as the famed Yamaha DX-7. The T8 is a monstrous sounding 8 Voice polyphonic synth with analog circuity under digital control, allowing the user patch storage and a 670 note on board sequencer, for programmable pattern playback. 

The T8 featured 76 weighted keys with full MIDI implementation, plus velocity and aftertouch that could be routed to various destinations, or used to control different note aspects—very uncommon at this time. This synth is very similar to its predecessor the legendary Prophet 5 in its sound and is often thought of as Sequential Circuits’ pinnacle synthesizer: Digital control of analog sound with an extremely flexible, intuitive and beautiful design – right down to the wood panels. 

The Prophet 8 had a bit of a tough time competing with the Yamaha DX-7, which was much cheaper, but for quality it was unmatched. Used by artists like Howard Jones and the Thompson Twins, it still sounds great: the Rolls Royce of analog synthesizers. Generally these beasts are hard to find today and still very expensive. 

In this particular repair, the customer had various complaints. We found the native procedure to reload all the internal factory settings. This involves setting program parameters by way of in-loading a WAV file, an archaic but effective procedure. In addition, we found the in-out jacks were iffy so we ordered and replaced those as well. 

Here is a Youtube video of a T8 being put through its paces.

LG TV Repair: 55LB5550-UY TV

It’s LG tv repair time again, at Bammel TV Tech Services. Customer brought in to us on May 23, 2018 his very nice 55″ LG smart TV for repair service, a 55LB5550-UY, with a complaint of “blinks, check out.” We put the flat screen tv in the service queue and prepared to perform our diagnostics.

LG Electronics is the latest iteration of the original Lucky Goldstar corporation. Founded in 1955 as Goldstar, during the rebuilding in the aftermath of the Korean War, they produced Korea’s first domestically-produced consumer electronics and home appliances. LG Electronics produced South Korea’s first radios, TVs, refrigerators, washing machines, and air conditioners. Bammel TV was for many years the authorized service center for Goldstar tv’s, and later for their full range of home electronics and appliances, including microwave ovens. We parted as friends, and we still perform occasional spot and request service for LG, on a case basis.

Together with Samsung, LG forms the “dynamic duo” of high-quality, low-cost electronics and appliance manufactures from Korea. The Koreans have totally laid waste to the giant and dominant Japanese consumer electronics firms, such as Sony, Panasonic-Matsushita, JVC, Toshiba, Sharp, Hitachi, and Mitsubishi. Japanese automobile dominance is not yet in serious question, but here too the Koreans have made serious inroads.

The 55LB5550-UY exhibited a full spectrum of 1080p grade LED-class hi-definition characteristics, including a 1920×1080 resolution with 120 hz refresh. Included were a range of connectivity optia, and good quality sound from two 10w speakers running Dolby’s digital decoder system.

After its time in queue was up, we benched the unit to the diagnostics lab of our chief technician, who made the determination of Backlight Fault: behind the display panel of modern flat screens is an array of high-intensity LED lights or lamps, and occasionally one or more of these will fail, leading to a variety of complications. In the past, we tended to quote for/replace only the actually-faulty lights, or the associated strips; but often other lamps tended to fail out. So these days, we’ve learned our lesson—we usually now replace all the LED-strips.

Summary: How we fixed an LG 55LB5550-UY TV

Our quote approved, we ordered and installed parts, and completed the TV repair. See this video for a full report and case study, from beginning to end-stage/final test, of how we fixed an LG 55LB5550-UY TV. For more examples of our art-and-science of TV repair, click here.

It’s TV Repair Houston time once again; in this case, Samsung UN55FH6200FXZA repair.

Customer brought in to us for tv repair service his nice 55″ Samsung flat screen tv, with a complaint of “long time to warm up, then flickering,” with some other associated issues. Check in date was 5/22/2018.

The Samsung UN55FH6200FXZA specs-page shows it’s a nice set, with 1980 x 1080 resolution and a 240 hz refresh rate. A good, solid smart TV, with two 10w speakers and Dolby/DTS-class sound.

We logged it in, shelved it; and carted it to the tech once its place in the queue was up. Our chief technician diagnosed the unit’s fault as due to primary fail of the main PCB. We completed diagnostics by 5/25.

From this point the admin/research/quoting squad gets involved, and performs standard database consultation and mining, plus associated vendor research to source the necessary part. In this case we came up with a repair quote both we and the customer could live with.

We developed our quote and, as is our wont, collected a special-order parts deposit to proceed. Customer approved our quote, and paid the supplemental deposit to order the main board on 5/29. We logged payment; created our internal Purchase Order; placed the part order; and waited with bated breath for the part to arrive.

We received the freight shipment by 6/4. We completed repair the same day—including a Special Video Shoot, for the Youtube channel and blog. Total turnaround time for repair was thus 13 days, which included the Memorial Day weekend and 4 weekend days, for a total work-day fix of 8 working days.

Here is a link to the Youtube video about this repair.

Marshall amp repair at Bammel TV


 May 23, 2018Marshall amp repair at Bammel TV

A report on a Marshall guitar amp repair ticket: we are the Authorized Service Center in south Texas for Marshall guitar amp repair—and for many other manufacturers, too.  Tube amp repair, solid state guitar amp repair: no problem. At Bammel TV Technology Services, we take pride in our reputation for thoroughness and integrity. Sometimes, we have found, in perhaps 5% of our repair tickets—we make our findings…and our technicians report…NO PROBLEM FOUND: evidently, as we sometimes say, “it just needed to get out of the house.”

In this instance, product had been brought to our shop for examination and repair of excessive noise or hum. Both our chief amplifier technician, and later the CEO, tested the amp and reported No Problem Found. A word about our procedures here seems in order; but first, some notes on the legendary amplifiers of Jim Marshall. (Interested readers are encouraged to check out the fascinating Marshall History page at the Marshall web site.)

Jim Marshall’s music shop began attracting local London talent like Pete Townshend and Ritchie Blackmore; these rockers requested louder amps than were then available in the mid 1960’s. Marshall responded by offering 100-watt amplifiers, powering multi-woofer speaker cabinets, producing near-deafening volume capabilities. The hard-rock era had begun, in earnest.

Along with Fender, Marshall amps represent the two most iconic names in guitar amplifiers. The DSL40C model, although assembled in Vietnam, appears to be an amplifier of very fine quality; sonically it produces a full, warm sound, with useful modern features.

Our approach is to shoot straight. We charge bench minimum fees, as these permit us to offer honest appraisals; we don’t do fake fixes. In some cases, as here, No Problem Found is the finding. A few customers grumble about paying diagnostic charges, but our reply is this: would you have preferred to be charged for a fake fix? We could have reported a fault, and charged you, essentially to do nothing. We prefer to maintain our reputation for honesty and integrity.
