Question about Toshiba 57H82 57" Rear Projection Television

Toshiba 57H82 57 in. Rear... Problem

Bill,

I saw this post below, can you email me the manual and if I remove the board, would you be willing to repair it? I trust you more than a local show unless you feel it should be a no brainer for them. How much would you charge? Email me the details please! Thanks for the info below, we were sad to see our tv getting worse and this has given us hope again.

This is a somewhat common problem having to do with the hyper module, Toshiba p/n#23148024
There are a gouping of 16v/10uf caps in the hyper board that fail causing the distoritions you're describing here. At first, as the module begins to go bad the distoritions are present and usuallly go away or fade significantly as the set warms up - - this gets worse until the distoritions don't go away at all... From what you're saying you're at stage three already. :)
You have a few of options: (1) local repair shop pull the board and replace the caps or module; (2) Pull the module yourself and repair or send it in for board level repair; or (3) pull the hyper baord, order a new one and put it in yourself.
For 2 or 3 you'll be better off having the service manual and if you need it just email me privately and I'll send it. Make sure in your request to tell me the model number and reference something of this repair so I have a clue of what you need.
BTW the hyper board is on the left side of the unit mounted vertical on the signal board inside a metal can.
Good Luck
Bill

Toshiba 57H82 problems


Val,
It's sent via Pando and you should get a link to it in your mail. To open it you'll need Pando, it's a free download if you don't already have it... The hyper module on that has about 10 caps that are common in that failure. If you need anything off board don't hesitate to ask.

Tom,
I'll send the svc manual directly following this post, but as a word of caution be EXTREMELY careful removing the smd caps. You can easily damage the traces and make the module useless.

Toshiba 50H82 hyperboard caps


Service manual won't help much in the hyper board and that's likely the problem.. Simply remove the hyper board and open the can. Inside you'll see a number of smd caps. There are 11 10mf/16v that need to be replaced...

YES - - - Will send the service manual with disassembly instructions - - just send me an email and remind me of the model number. I get nearly 3000 emails a day and I'm over 50 so I'm likely to forget this post in an hour or two. :)

Toshiba 52hm84


It's either signal board or light engine and unless you're really pretty good at electronics neither one is something you should tackle. I do have the service manual for this unit and I would be glad to send it.. Just drop me an email premtech@willapabay.org and make sure you include the model number as well as what it is you need.. I get almost 650 emails a day so it's really hard to remember who's email goes with what problem. :) Good Luck Bill

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
