Toshiba 56" rear projection

Hi there, I just had the convergence ic units replaced in my tv. The parts were worth $ 70 but the tech charged me $100 call out fee and $ 250 for labour for a 15 minute job. Is this usual?

    Well if I had been quoted prior to the job, I would have shopped around to find out how long it was supposed to take, according to the company, the tech booked over an hour and I clocked the time ( luckly for me ) he arrived and left. The company told me that it should have only taken 15 mins to replace the parts....and thats all the time he was here anyway... As it was I got extremely sad with the company and they have promised to refund my money less parts....result!!

Yes a repair tech will usually cahrge 400 minimum to do it, and sadly it takes less than a half hr start to finish.

My Toshiba 53H71 rear projection TV's picture looks like double vision with a heavy tint outline how can I fix this???


Hi,
Double vision/ picture problem occurs due to failure of convergence output ICs in rear projection tv and it is common problem of projection tvs.
Please replace convergence output ICs in tv to solve the issue, there is convergence repair kit available for $70 on This Site that has required parts/ ICs, instructions about how to replace ICs etc for a handy person.
Hope these info will help.
Thanks.

Here is a power supply tech manual:

There are several circuits in the tv that will cause this. the most common on your model is a bad convergence circuit. a repair cost will range around 400.00 or so. it is a good model and worth a repair.

STK392s didn't solve the problem


Hi. Im not 100% familiar with your model toshiba but they are all similar so try this. (1) RESOLDER MEMORY ICS ON THE TEXT BOARD, A COUPLE OF THE LEGS LIFT OFF THE BOARD. (2) RESOLDER ALL PINS OF THE OUTPUT IC'S, EVEN THOUGH THE DON'T LOOK DRY: Q750,Q751 AND Q753. RESET CONVERGENCE IN SERVICE MODE. CHECK RESISTORS, CPS, & REPLACE ANY BULGING CAPACITORS NEAR THE CONVERGENCE ICS. As I said im not to familiar with your model it may or may not have the exact components I have listed in parts (1)&(2) But its worth checking just in case it does.

Toshiba 56H80 Convergence Problem?


There are 2 large IC's in your set and one of them has burned out. These are called convergence output IC's and are usually the STK392-010's. A good idea would be to go ahead and replace both with the newer, upgraded STK392-150 IC's. A good tech can change those IC's in about an hour and a half, and when I do a housecall for a set like that I charge $150, but shops in your area will vary so be sure to ask around.
