Re: Additional info on Toshiba TP43H60 convergence
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/

You are describing the MASTER SCREEN/ FOCUS CONTROL BLOCK---black with six controls--three are red, green and blue focus--the other three are screen controls--red, green and blue--- the screens are adjusted so with the color off you have normal brightness and a black and white picture--
They have nothing to do with any Convergence problem and unless they have been tampered with rarely need to be adjusted---
Let me know if this helps you AND IF YOU HAVE ANY QUESTIONS OR NEED ADVICE--LET ME KNOW.
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.
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.
Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.
You have a bad regulator IC or something in the seweep power supply is blow out. if you can read a schematic, i suggest you get one to troubleshoot the solid state circuits in this TV set. if you do not have any solid state repair experience or no electronic background, play it safe and call in a pro to assist you in the repair of this TV set. Good Luck.
