for Yamaha Clavinova Repair, Call Bammel TV

Yamaha Clavinova Repair at Bammel TV Technology Services


Like any piano, over the course of time a digital piano can get hammered—so to speak. All too common is the user, typically a youthful one, who dreams he is Jerry Lee Lewis working out on some ancient tank upright, or playing a million-dollar Steinway piano at Carnegie Hall—although even this class of instrument is not immune to the effects of excessive force. If you stomp on the piano too hard, even in a stomp-piano style, folks, you WILL damage the keybed assembly components!

We see it all the time, and recently a customer brought in a fine and classic Yamaha Clavinova, with fine and lustrous wood, bearing the hallmarks of juvenile abuse: numerous recessed keys, their hammer-weight individual mechanisms damaged or destroyed by excessive playing force.

In some instances we are able to perform individual keybed-component repair; indeed, in some instances we’re forced to do this, or attempt it; but the preferred solution is typically to simply order and replace the entire keyed assembly, which lends a fresh-start approach to the repair operation and the instrument gets a new lease on life. The Clavinova’s were a fairly high-order instrument in their day, requiring a substantial investment. The sound and tone are still great, even by today’s modern digital piano standards, so we very much enjoy restoring these instruments whenever we are asked to do so.

In some cases we’ve run into some No Longer Available parts situations, on some brands; fortunately here this was not a problem. The recommended treatment, replacing the entire keybed assembly, was still a feasible option.

Summary: Yamaha Clavinova Repair successfully completed, at Bammel TV. 

We’re the go-to guys in Houston for Yamaha keyboard repair (and many other brands as well; visit our main Digital Piano Repair page for more information), including the sweet and coveted Clavinova’s. We sourced the part, developed the repair quote, briefed the customer, ordered the parts, and fixed ‘er on up.

May 2017: Vizio TV repair, model E500I-AO

image of a Vizio tv repair done at Bammel TV

Vizio entered the American TV market as a complete upstart in 2002, with 3 employees and a $600,000 operating budget—total. By 2007 company revenue exceeded $2 billion—an amazing feat. Known for their highly aggressive pricing vs their top competitors, Vizio hit the American market hard, quickly laying waste to far-better-known manufacturers. In their wake come other ultra-low-cost Chinese televisions, further challenging the position of the legacy Japanese manufacturers—and the repair market generally.

Questions have arisen on the feasibility of Vizio tv repair: is it feasible to perform flat screen tv repair of these low-priced TV’s, usually assembled with cheap labor in China? As we have stated in our free White Paper, “Is It Worth Fixing?,” the answer is: it’s a definite maybe. Almost always, each repair prospect must be individually assessed by a senior tech, then researched and sourced, then quoted to the customer. Not all televisions are suited for repairs—we only fix 90% or so!

Here, proof positive of the primary principle: when in doubt—Call the Professionals! Call Bammel TV!

It”s the final QC check on a backlight repair job, a 50″ TV repaired for No Picture complaint.

In for service, a Sony Shake-99 audio/video system. Customer indicated a complaint as follows: CD STUCK…RECEIVER OUT—NO SOUND.

Need Egnater guitar amp repair? We’ve added another splendidly sharp arrow to our highly diversified quiver: Bammel TV Tech Services is now the Authorized Service Center in Houston for Egnater guitar amplifiers.  Scoring this certification adds another premiere guitar amp manufacturer to our (already illustrious) profile, which includes Marshall, Fender, Peavey, Crate, Hughes & Kettner, and Randall—add Egnater now to the mix.

Kudos to co-manager Dean Doba for liaison work with the manufacturer. In the course of seeking parts support for repair on an Egnater 4-100, Dean was able to break through the typical manufacturer firewall and get us set up. Lots of manufacturers still need highly qualified service centers to address occasional problems with their units. We fit the bill for them!

We received an Egnater product recently for service, brought to us by the local Music Go Round store, with a complaint that the unit’s high-gain channel was nearly inaudible. To judge by our overview of this Model 4-100 unit, it is an extremely well-built, versatile and rugged guitar amp, with numerous and flexible hook up and rigging options. According to their website, “Egnater Amplification is today the fastest growing guitar amp manufacturer in the industry.” To judge by the 4-100 product, we can see why this might be the case.

For this particular product repair, we did our initial assessment; technician at that point requested the product service manual. This is not always necessary for our expert technicians, but in some cases there’s simply no way to proceed without a service manual and circuit schematic, along with block diagrams, parts lists, and the like. Fortunately in this case, we were able to get the 4-100 amp repaired with a physical repair (repair of cold solder or connexion fractures) on the high-gain channel of the amp.

If you need Egnater guitar amp repair, call the professionals—call Bammel TV.

Our report on three repairs performed on a customer’s Line 6 Pod Pro, his Rocktron Prophesy, and his Digitech GSP2101.

This customer owns ALL THREE of these classic units! It’s guitar pedal repair time at Bammel TV Tech Services!

Pod Pro Repair

The Pod Pro is a classic 2-rack space effects unit from Line 6. Capable of multiple simultaneous effects of the classic sorts: distortions, delays, dynamic effects, tremolo, wah, reverb, pitch shifting—a wide tableau—no, make that a panoramic sweep of tones. With dual XLR-outs as well as digital outs, and multiple possible input configurations, these were excellent machines. We haven’t seen very many, but as the authorized service center/master service center in Houston for Line 6, when those products need some TLC and attention, we’re the destination of choice for the customer.

In this case the Pod Pro exhibited periodic loud screeching noises—obviously hideously unacceptable for a guitarist. Specifically, the customer complained of a “Works 12 seconds, screeches 12 seconds” phenomenon. Our master techs would have liked to get the Main PCB for this repair, but it was NLA from Line 6. That left us scratching our heads…We came up however a solution: we REPAIRED the main PCB assembly fault. We ordered up an IC from China and were successful at restoring this high-quality unit.

Rocktron Prophesy Repair 

The same customer also brought in a Rocktron Prophesy—one of the classic units designed by Tom Scholz of Boston.  This unit was simply dead, exhibiting a no-power symptom. We isolated and replaced seven discrete faulty components, and unit is restored and back to proper operation.

 Digitech GSP2101 Repair

Finally, customer also brought to us his Digitech GSP2101—another rack-mounted classic effects unit (and one of our personal favorites.) The 2101 was/is/remains legendary due to two 12AX7 vacuum tubes (or valves, as our British friends call them)in the preamp section, permitting a wide range of natural analog tones, from crystal-clear-clean to radically saturated distortions—that’s in addition to a huge range of digital effects, on top of an analog compression/EQ/gating stage. Altogether a wonderful unit, which fortunately in this case required only minimal service to restore.

Summary: When you need guitar pedal repair…

Restored Vintage Zenith Console Stereo

Console Stereo Repair

Customer recently brought to us for restoration a classic, vintage Zenith console stereo, model #MH2602M, bearing a chassis designation of 4G21 9H20. We estimate this unit was from the late 1950’s or quite early 1960’s. Customer reported “retro appeal” on the unit: it being fashionable to come to her home and listen to vinyl discs on the stereo console. But her kitty-cats had gotten out of line and clawed up the grill cloth—quite badly—one of the worst cases of pet clawing damage we have seen! BAD kitty! (Customer indicated she has subsequently declawed the little villains, or otherwise disarmed them.)

But, as pet damages go, this one wasn’t amongst the very worst. We did a restoration/replacement of the speaker grill cloth, using material supplied by the customer. Additionally we did some cosmetic treatment of some critical internal fixtures, cleaned all potentiometer controls, and repaired/re-aligned the display glass, which had slipped out of alignment.

We’ve fixed many, many vintage and console stereo units for customers. We’ll add more posts “in future,” as our British friends say.

nest pro installer logo

November 9, 2015

We continue to expand the already-huge range of services we provide. Now, we are thrilled to add the Nest Pro Installer accreditation to the list.

The world of smart home automation has become much more than just having a “connected home” or house with some things hooked in to the internet; now, the drive for AI or artificial intelligence is coming home—literally! The very house around us is now capable of exhibiting intelligence. It doesn’t just look cool or respond to programming (although it does do that!); the drive towards modern smart technology is moving towards our homes actually anticipating our needs.

Nest products are at the leading edge of this movement. Those who have heard of Nest may be familiar with their famous smart/learning thermostats, but the company’s agility is huge: they are now offering Nest Protect smart cameras and smart home alarm systems. These products feature great “interoperability”—kind of a buzz phrase, basically it means they talk to each other, and to other products connected via a widely-used communications protocol.

If you have further questions, or need Nest gear installation, call us up to schedule a free in-home advisory. Take advantage of our expertise. You’ll also get 3 extra years of product warranty coverage, just for using a Nest Pro installer. For more information, visit our Smart Home Houston page.

On Tuesday the 13th of October, four of us left Houston bound for the Big D—Dallas TX, site of this year’s CEDIA Expo: the annual trade show for the Custom Electronics Design and Installation Association. A ton of planning-and-logistics headaches later (as well as a significant dollar investment later!) we returned to Houston Saturday, October 17th, much the wiser for the experience.

We planned for a very extensive suite of training classes for all four of us, with the idea of “going all in” to the growing field of Smart Home Automation: cram and amass as much exposure as possible into four discrete brains, then start bouncing ideas and possibilities around, and hope for some good outcomes.

We found that it’s difficult to gauge in advance the training quality and utility of the CEDIA classes. Several were not only excellent but into the domain of the revelatory, while others left a decided “meh” impression. Knowing what I know now, I’d have picked a less expansive/less expensive class schedule for the crew; but of course you know what they say about hindsight.

In the end however the overall results were very good: we gained an overall understanding of the scope of this enormous market, as well as an angle on how we might be able to find our niche within it; in particular, for us the growing fields of Smart Home design and Automation and Commercial Audio appear to hold the most promise. This will involve an app-based focus regarding actual smart home automation and control.

This tendency in the market, towards app-based control, will (in our opinion) eventually make life more difficult for the large-scale control platforms; but given the enormous profusion of smartphones and tablets, and the ramping-up bedrock for integrated apps through such services as Apple’s HomeKit, this outcome appears inevitable.

Stay tuned for additions to the Bammel homepage, for Smart Home Houston and Bammel Commercial Audio!
