I have a Toshiba TP43H60,The convergence is off in the top left and top center,I replaced the convergence IC's (stk392-110)with no change.I checked the resistors around the IC'S.Still couldnt adjust the convergence correctly using the the remote,the red is the one with the problem;it is bent at top. I was going to order the service manual but is not avalable.

Have you tried to adjust in the customer menu or in the TECH menu? I can tell you how to get into the tech menu--if it will not adjust there you have a convergence circuit problem and I can tell you what is needed to repair the set.
Good Day, harri1234;
Sounds like a convergence problem. Convergence Output IC Failure Corrective Action: 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. Good Luck, Big Irish.
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.
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. http://servicemanuals.vstore.ca/
If you need any additional info please let me know.
DA, convergence circuit has failed, the IC`s and possibly a couple of support resistors need to be replaced, your right about it being a good set, 6 years is about average for convergence IC`s, call your local shops for a few estimates and get it fixed, it will run for a lot longer than 6 years, hope this is the advice your looking for, e-mail me if you have more questions, BMW Rider
I retired from the TV repair business because if you are not an authorized repair service center most manufacturers will not even talk to you. If you are electronically inclined you can repair this tv. your problem is a bad convergence ic. you need to be able to locate it and replace it. it probably has about 15 or 18 legs that need to be unsoldered and a new replacement re-installed
One of your convergence IC's has burned out and needs to be replaced. If the green color is sagging from the top or bottom then the IC that handles the Green Vertical (GV) is bad, and if the green has moved inward on the left or right sides then the IC that handles the Green Horizontal (GH) is bad. Toshiba projection TV's typically use the STK392-110, and it is a good idea to go ahead and replace both IC's with the updated STK392-150's. If you do not have experience replacing convergence IC's then have a qualified tech handle it for you.
