You need to replace both convergence ICs part number STK392-110 this requires basic soldering not very difficult. If you order the new ICs at the link I am posting they provide free instalation instructions with pictures and free tech support so you can do the repair yourself and save about 400.00 heres the link.

Toshiba model 61h71 red light comes on /no picture or sound


We had the same problem, open the panel on the back of the tv, the board on the left, not the one with the convergence chips. Inside the tv u will see a piece of paper with the fuse info. The board on the left unscrew it and flip it away from you, the fuses to test are at the bottom, on the circuit board it will say 125volt 5 amp, and the number starts with an f. they are small and rectangular and black. Check all but the 3 at the bottom are usually the culprits Hope this helps u

Picture problem Model Toshiba 61H71


Hi, convergence circuit has failed, IC`s and probably 1 or 2 precision resistors will have to be changed, not really something you can fix if your not an electronics tech, BMW Rider
