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!

I have a Toshiba 55H70 TV. Lately it has been having issues with the screen. The picture will go out and theres different color lines, if we turn it off or unplug it and plug it back in it comes back. we...


Sounds like possibly cold solder connections on the convergence IC's I believe there are 3 in your tv. They are easy to spot big black IC's that have STK392-xxx stamped on them.. If your lucky you can solder the connections and be back in business. Sometimes because of the bad connections left unrepaired it will cause the ic's to fail then they would need replacing. If you have soldering skills you might try yourself. Be careful and make sure its unplugged. If you arent skilled at soldering I wouldnt recommend even trying it.

Convergence in Toshiba 43a62 projection tv


its not likely to have come un soldered or loose, a lot of times when you move a big screen they have to be reconverged. not because of damage but because of the move in general...i would call a shop and have them come out and re converge it. that what it will take to get it done right

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)

Big screen TV


chances are the repair man wanted to sell you a whole board because with mitsubishis this problem is amost always the convergence ic's also in that model very seldom the resistors burn out in that unit its almost always the IC's that do that. I looked for you information you have an old chassis but I think its similar to the Vz2 I believe you need IC number STK391-020 thats based on theVz2 chassis but pls double check and you need 2 of them you can also save yourself if you know how to solder a lot of money by replacing them yourself its about a 45min job if I can help you any further pls let me know or if you would like a link where you can buy your parts very reasonable with tech online support let me know
