Yes. I did get my Toshiba 57H81 Fixed. But the remote control doesn't work afterward. I have to pull the mainboard out again to see if there is any problem during the IC replacment.

How do i fix my toshiba flat screen 57" tv when it looks like it is 3d


Howdy;
It sounds like the convergence IC's have failed.
Replace the defective Convergence Output IC Part Number 23905094 (STK392-110) using the revised “T” version IC Part Number 23135090 (STK392-110T). When Convergence Output failure is detected, it’s recommended that both IC’s be changed to the “T” type IC version. Inspect the Convergence Output IC’s for the “T” type version.

I have a toshiba big screen tv we believe both convergents need to be replaced we do not have 300-365.00 to repair it . I know how to solder can I do it myself???? model#57H81


convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually charge between $200-$400 Be sure to vote/rate me if this helped Thanks!

Toshiba big screen The tv is like double exposed . I have a toshiba big screen tv and I have double images in red and green. How do I fix this problem?


This is likely your convergence ICs(chips). If you can bump it then the ICs (chips) are still ok, it just needs resoldering.
my company charges $300-400 for the full repair (replacing ICs, full realignment plus cleaning)
if you can find a company that will resolder for you, it could cost $100-200 maybe. if you are a handy person with soldering skills, you could repair yourself. i can instruct if needed, but convergence IC soldering requires decent soldering skills. you will find the ICs on the largest heatsink in the tv. the part number starts with STK. if you replace them, check the resistors in front of them and replace accordingly. most toshiba will blow up to 3 fuses (f850, f851, f852)

T.v. problem


This is a convergence issue. Have you tried going thru the convergence touch-up thru the menu?. If you have and it does not cure your problem, the convergence ic flat packs have to be replaced. The average repair is around $200-400.
