Blinking power light & black screen on toshiba 57h81


This TV could have one of several problems including but not limited to; convergence IC's,bad capacitors, shorted horizontal output transistor. Call a good TV Tech. Check with the BBB before you decide on one.

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...

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...

Toshiba 57H81 picture bounces. Can't tell if horiz. or vertical.


Unstable picture, wavy, jittery, and loss of sync are a symptom of bad capacitors in the hyper module. The problem is worse when the set is cold, but when warm the sympton gets less or goes away. In the latter stages the problem never gets better even after the set has been on for hours. There are about 6 surface mounted caps (10mf/16) inside the shielded Hyper module. The module is vertically mounted behind the jack panel and can be unplugged from its socket after unsoldering the 4 anchor tabs on the bottom side of the PCB. This type of repair should be made by a qualified technician do to the complexity of chassis removal and expert soldering skills.

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

Service manual (schematics)


I just bought a service manual on Ebay. I'm not at home so I don't remember the vendors name, however it was $8.50 and the documentation seems complete. I also just found this site: www.john-oliver.net/video/50H81.pdf which contains a block diagram but not the full set of schematics. If you really need the schematics let me know and try and get them to you.
