Trying to manually fix color convergence on Toshiba 57H81


The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

Convergence problem on a Toshiba 57h81


A service manual won't help you on this and yes it's most likely the convergence amps. That unit takes two stk392-110 Sanyo amps. You can substitue with stk392-150's or 180's also... Personally I'd get them from acme sales in florida along with any solder, de-soldering braid, heat sink compound and other supplies you'll need for the job. Acme, because you are assured of getting originals not some chineese knock-offs.
I'd suggest a package of 1.8 ohm/2w resistors, looks like that's what this unit uses in the yoke return circuit and they commonly have failed, and likely the cause for the amp failure. You might also take a meter to any picos in the circuit. F850, 851, 852 and see if any of them are open. If the amp opened you're okay, but if it went to ground it may have opened a fuse.
I will send the manual via Pando - so if you don't already have Pando go there first and download their free program.

Toshiba 57H81 service manual


A 57H81 is not easily disassembled and I wouldn't suggest that over getting a pair of forearm forklifts and a couple of guys to load it in the back of a pickup...
The sevice manual will not show the brakdown you need - and it's not really practical. Guess that's why movers should stick to moving and I'll stick to Tv repair...

Convergence ICs - Toshiba 57h81


they send the instalation instructions with the ICs , which tells you what tools you would need and exactly how to replace them. yes both Ics should be repalced together as they work together to control the 3rd color. yes STK392-110 are the correct ICs for your model.

57H81


Kevin,
I'll send over the link for the manual to your personal addy but it won't be much help I'm afraid with identifying and removeing the hyper module. The hyper module in that unit is a square metal can standing vertical on the signal board just behind the jack panel - - leaft side looking into the back of the TV...
Screw driver and some real patience and it should be no problem to remove. From there send the module in and have it repaired and you'll be glad you did...

Service manual, Toshiba 57H81


Send me your email address and I'll send you a Pando link to download the schematic... The caps you're looking to find are Cx261, Cx270, Cx230, Cx178, Cx221, Cx250, Cx670, Cx241, Cx541. You might also check C514 and C5030 all are 10uf\16v but be VERY careful not to screw-up the pads lifing the smd caps in that module. Bill premtech@willapabay.org
