Toshiba 55h70 Convergence IC


I used the SONY stk180's on my 55h70 and works great...2 years no problem.

Get the real thing though....the knockoffs do fail

I also made sure the contact surfaces between the IC's and the heatsinks were properly cleaned and used "Arctic Silver Thermal Paste" applied in an even thin coat on all contact surface areas.

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

The convergence IC needed are STK 392-110 two of them and possibly a resistor or two If you don't know how to unsolder and solder I would suggest an honest repairman. most Parts distributors won't sell unless you have a business but you could try anyway. A volt-ohm meter is required "IF" a resistor needs to be checked or is burned. Convergence IC's are a common problem with all projection tv's. It may last another 5 years especially if you don't buy the generic ic's

Toshiba Theaterview HD 52"


I have the same tv and had it fixed the problem is most likely the power supply a $50.00 part but I suggest you have a repairman do the fix. Total cost should be around $250.00 for labor and parts.Also unplug your tv for over 4 hours then plug it back in to see if it works they call this a hard reset.If this does not work after 4 hours try unplugging it overnight and then try it. That is what I did to use the tv until I got it fixed. The only thing it could be is the convergence circuitv if this is the case it should cost about $400.00
