Question about Toshiba TP43H60 43" Television

Additional info on Toshiba TP43H60

I had replaced the STK392-110 ICs,checked the resistors around
them and they check fine.There was no change in the picture,I guess my question is there a setup in the service menu that would be in the service manual for convergence or is there any other part that would be causing the
red not to lineup at the top.

    One leg of all the resistors were pulled and checked around the

    convergence IC's and they all checked good.Anything else you can think ?

Sounds like maybe a fusible resistor has opend. Did you remove one leg of the resistors out of circuit when you checked them? Also some toshiba models had fuseable links near the ICs some mounted between the fins on the heatsink and others were solderd directly to the circuit traces themselves.

    did you see any small fusible links solderd directly to the bottom side of the circuit boards traces themselves? If so just check them for continuity in circuit. If that doesnt solve the problem you will need to troubleshoot the entire convergence circuit for the red as there may be a bad capacitor. Do you have access to an ESR meter to check the capacitors in circuit?

Cannot converge blue -- yellow and blue "doubling".


Your convergence board is in need of new convergence ICs...Or if you are lucky,maybe just checking for rings around the ICs for bad grounds.Please solder these if this is the case. And Always check the resistors as values change...these are usually 10 ohms or less!

This may sound odd but try moving the remote further from the set. I have seen similar issue with my 42H81.

check R7059 and R7050
check for 2.2 ohm.
if not 2.2ohm replace them.
values are 2.2ohm at 2 watts
also look for bad soldier around all serounding resintors.

I am not sure what your needing help with , however its posted under convergence . Your set if having difficulty with aligning the colors will need to have both Convergence ICs replaced. This is an easy repair you need two STK392-110 Convergenve ICs. You can get them at the following link just click on the section titled Convergence IC and you will see your ICs listed there. They also include step by step instructions with pictures on how to remove the old and replace the new ICs as well as set you up with a free online chat session for support while your doing the repair. Heres the link.

TP43H60 component input color issue


From our experience letting customer dance around in the service menus usually they end up with a problem way worse or a dead set. It would be best to check the cables first, After looking in the service manual it appears there are no separate brightness or gain controls for componet but if you still need the service manual I can E-mail it. But once again more sets have been destroyed by a customer just tweaking things a bit in the service menu

Rec convergence will not work


Your IC's likely need to be replaced. Also check your resistors that corrispond with the IC's. Here is more info on this.

Resistors on toshiba 50h72


The resistors are located right next to teconvergence ICs.An ohms meter will check them often you have to lift one leg out of circuit to test as they have to be within 5% tolerance. You cant miss the resistors right next to the ICs heatsink their should be quite a few of them all identical.
