Where can i puchase convergance output chips for my toshiba theaterview rear projection tv?


If model number listed is correct it uses two of the STK-392-110 chips.

Suburban Electronics in Maryland is the best choice; they have both an 800 number AND a online catalog as well.
Fast shipper and good prices.

Convergence problem red lines are out of wac on


Most of these sets use two STK-392-110 convergence IC's; both along with any open resistors around them need to be replaced and the set adjusted.

You can buy the chips on Ebay for less than 13 dollars(look for suburban electronics--Sewsale--they have the best price on these parts and give a 6 month warranty) if you are able to replace them yourself if not, look for someone in your area to do the job for you; this is the slow time of year for TV repair shops---some shops get 300 or more for this repair. I fix a lotof these smaller sets(42 etc) for 200 parts and labor.

Find someone and make sure BOTH IC's are replaced. If you have questions let me know here. I do this for free so if this was helpful give me a vote here.

Toshiba 43HX70 convergence problem


One or both of the STK convergence chips have probably failed.

I can give you guidance on this if you are confident to do the repair. I had the same problem with my Tosh 40WH08B and after replacing these chips it works like new.

Toshiba projection TV Flickers


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.

Toshiba convergence


There are kits available online, which include the chips and the soldering iron too.......Just a word of caution, convergence chip replaced is more difficult on Toshiba #1 the chips face other boards that must be remove first. the main one is the convergence generator (which the sheild is soldered in placed) Also the signal board (which is what everythings mounted to is very fragile)..............Good Luck
