Yup: below you will find a little “Return of the Jetsons” video post on a 1970 JVC Videosphere television repair: a CRT-style/picture-tube-type TV, in glorious black-and-white. Customer “found us on the internet” and brought the TV to us with a complaint of “low sound.” We were able to solve the problem and complete the TV repair, recapturing a moment from the customer’s youth, with a most definite coolness-cachet for his cadre o’ compadres.

JVC (Japan Victor Corporation), founded in 1927, produced Japan’s first televisions. They introduced many innovations and high-quality consumer electronics, including the VHS recorder. They began production of this space-helmet gem in 1970 and sold them into the 1980’s. I don’t recall ever seeing one or fixing one at the shop before (sadly, this one lacked the add-on alarm-clock-base feature! As they say these days: want!)

As you will discern from watching the video, the CRT (cathode-ray tube, in the original parlance; “cathode rays” are electrons) or picture tube is still going strong on this one, and looks great. CRT lifetime is variable; picture quality attenuation can begin at any time, but we’ve seen CRT’s still looking very good after 40 years or more. For older products, we often dial in a composite-video feed, to enable viewing modern video devices. CRT’s were often very hardy. While a step up from early rotating-disk mechanical televisions, the mass and weight of CRT’s eventually gave way to modern plasmas, then LCD’s; coming next: placemat/rollup screens.

Here, we diagnosed and performed a pretty simple and routine fix: some reconfig and resoldering in the audio circuit.

We do it all—including JVC Videosphere repair! For a wee bit more info on the JVC Videosphere, click here. For our TV Repair Houston page, click here. To get a Quick Quote on YOUR repair, click here. For our FAQ page, click here.

How We Fixed a 24 Track MCI JH-24 Recording Deck

How We Fixed a 24-Track Studio Recording Deck

Customer brought to us an early-1980’s vintage studio recording deck: a 2″ tape, 24-track recorder—the MCI JH-24.

The MCI JH-24 is a rather legendary studio multi-track recorder—a very impressive piece of equipment, the first commercialized 24-track recorder. Many rock classics were recorded on MCI machines: Eric Clapton, the Eagles, Led Zeppelin, and the Bee Gees recorded many of their 1970’s era hits on MCI 16-track machines. The JH-24 carried an original purchase price in the $30,000 range. Even today working units are being sold online for over $8000, not including freight.

By the early 1980’s digital recording was emerging on the horizon, but many artists then, and still today, prefer the perceived “warmth” of analog recording equipment. And so we found ourselves facing a non-functioning JH-24 deck—the first one we have seen.

Assessing the Repair Prospects on the MCI JH-24, and Phase 1

Customer’s complaint was that “Tape transport won’t function.”  Our diagnostic assessment found the following:

“MAJOR RECONSTRUCTION REQUIRED in POWER SUPPLY, STANDBY CIRCUIT WORK, and SYSTEM CONTROL CIRCUIT. ADVANCED TROUBLESHOOTING PLUS REPLACE OF MISC COMPONENTS INCLUDING DISPLAY LAMPS—HOWEVER IT IS OTHERWISE IN GOOD SHAPE AND REPAIR IS FEASIBLE & RECOMMENDED FOR REPAIR.”

After considerable efforts by one of our master technicians, our repair essentially stalled out—“I can’t fix it.” Despair set in. Eventually I transferred the ticket to our other master tech and assigned him a full time assistant for this challenge. The risk was considerable: should he and his team flame out, and the unit prove unrepairable, this would represent a large loss of valuable repair production time.

Phase 2: Breakthrough

The second tech team completed the remaining work, but having done so, we ran into additional complications with this very complex product. Customer had requested that at least 16 of the original 24 tracks be restored. As it turned out, each individual recording track presented individual electronic circuit issues. Both our master techs worked on the unit, and were finally successful in restoring 23 of the 24 tracks, each of which required individual troubleshooting and circuit repair, for a total repair cost below $4000—thus saving the customer over $4000 off the cost of purchasing a replacement.

Summary: We Fixed It

Finally, we presented the triumph to the customer: a restored, functioning MCI JH-24, at just half the cost of a working replacement. Just another save-the-day at Bammel TV Tech Services.

Treadmill Repair Report at Bammel TV 

Treadmill repair at Bammel TV

Customer brought to us his Weslo Cadence DS11 treadmill for treadmill repair service, with the following complaint: “Unit powers on, but nothing activates.”

 The Weslo DS11 is a lower-priced treadmill in the market, with a pretty low hp motor and 4 stock incline positions. Often found at $300 or below, could such a low-cost unit be economically repairable? To ask the famous question: was the product worth fixing?  Yes!

We found that the unit’s control board had an intermittent cold solder connexion (we like British spelling, sometimes.) We repaired the connection and unit was picked up, saving the customer considerably off a new replacement.

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.

Customer’s Delonghi Gran Dama deluxe espresso machine was brought to us for service on January 21st, 2016, with a complaint as follows:

“I get a message, it says ‘add beans,’ I add beans and start grinding. then it stops and says, ‘add beans’ again.”

Our master techs and support staff were on the case by January 21st; we determined that the grinder had gone faulty and would have to be replaced.

Upon completing the parts research and vendor sourcing phase, and obtaining manufacturer’s part # for the grinder, we found that one of our reliable parts vendors, Encompass Parts, had the item in stock.

We obtained approval from the customer to proceed with the purchase order and repair on February 9th; part was in on 2/17, and the grinder installation and quality control testing completed by 2/19.

As these units go for ~$2000 used on eBay, and we fixed it for $385, you might say we saved the customer $1600.
