    Are there three chips for red, blue & green?

  • gtracy2117 Feb 18, 2008

    I had convergence chips replaced, and the repairman resodered suspect connections. TV worked for a couple of months with perfect resolution and then sudently went back to the same flickering and shutting down. It has been in a local toshiba dealer repair shop for two weeks and they say they cant find the problem. They said they replaced a couple of bad capacitors but didn't help. They suggest I buy a new TV?

You may have bad convergence chips in the set. I have worked on some with similar problems and replacing the convergence chips was the solution. Good luck and I hope this has helped.

    Unless you have a older set ( 6 years old or older in most cases ) there are only 2 convergence chips. The number normally starts STK. ( ie: STK 392-020 ) . If you have an older set, you may have 3 chips or maybe even just one controlling all three colors. I hope this has helped.

Picture often flickers and image distorts every few minutes
The trouble is most likely in the Video processor. If the trouble looks like its tearing the video only from side to side it may be the line doubler circuit. Some of these boards are no longer available but a good TV tech may be able to componnent level repair it for you.

Toshiba 42H81 - Screen flicker
Since the problem initially would correct itself, it suggests a poor connection somewhere that "heat" would resolve. If you can solder, try resoldering any joints that appear to be grainy or have rings. Please note that these sets will retain high voltages that can be dangerous even when unplugged. If the resoldering fails to resolve the problem, let us know and we'll look further.

Thanks,
Dan

Projection TV keeps shutting down
Good Day;

Sounds like you have a bad green picture tube that has failed. To check this out; remove front speaker grill, remove small panel, you will see three CRT's (pictue tubes) sticking down, remove the little board on the middle tube then restore power. If TV stays on more then likely the CRT is bad but not always the driver on board could also be bad, check voltages.

Good Luck, big IRISH.

Flickers caves in on sides then shuts down
I can understand the frustration of the repair shop, as getting help from Toshiba is almost non existent. When the boards in any big screen gets hot and used, many components on the board degrade and in your case, it sounds as though the fix would be a replacement board. Unfortunately, you may not be able to get one. If your local repair shop can't find the problem you might ask them for the board number and do some research on your own for a board. Most wholesalers will sell to the consumer if you have a credit card, and if you can find the board, have your local shop install the new/refirb board and do whatever adjustments are necessary. Good luck. I hope this has helped in some way

Tv problem
Hi,
I just serviced this model, same problem as noted. I did a resolder job on the power/drive PC board. This was NOT the problem! The problem acts like an electrolytic capacitor issue or horizontal drive amp. Once I get my hands a service manual & schematics, we'll resolve it. I'll post my results AFTER Super Bowl.
