Toshiba - 50H82 service manual

Toshiba or any authorized service center can pull up the photo of that board (the 10 caps that fail are all indicated with red arrows) you are aware they are surface mounted caps?

If the video is shaking, zig zag looking, etc your hypermodule has failed. This is common on your model. Some peeople call it hyper board, hyper module, etc..all the same.

You can get a repair kit for this from www.TvRepairKits.com

If the tin can module you are referring to is the hyper module, it is common to replace all 11 caps because the factory caps ****. Check for bridged solder connections at STK's search the forum at electromaniacs for 50h81 :)

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.
Bill

Jimmy,
Will send it out post haste... But be VERY careful inside the hyper module you can easily lift the traces when trying to remove the smd caps and ruin the module beyond repair...
Just send me a private mail and I'll return with the service manual.

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...
Bill

Needs to have the hyper module repaired... There are a group of caps on the hyper that need to be replaced... The hyper module is a stand-up board on the left looking in the back of the unit just behind the jack panel... Need to remove it and send in in for rebuild or attempt the repair yourself..

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

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 [email protected]
