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...

Toshiba 50hd82 Hyperboard


By your question alone the best place to start would be a good repair shop. The hyper module needs to be removed from the main chassis. After removing the two outer covers locate Cx261, Cx230, Cx270, Cz52, Cx178, Cx221, C514, Cx250, Cx670, Cx241 and Cx541. These are all 16v/10uf caps SMT but most techs simply replace them with the sub mini radial caps.

There are about 6 or 7 surface mount capacitors 10mf/16v that cause the symptom you are having. They are located under the shield of the hyper module. The hyper module is located behind the input jack panel in the back. The module is vertically mounted and can be removed from its socket. However you must first unsolder the 4 anchor tabs of the shield first. Thats the easy part. Removal and replacement of the capacitors requires precise and excellent soldering skills. This job should be left to someone who has done this a few times. Hope this info helps.

Dougers, I am next door, in Alberta. I have fixed my hyperboard by replacing the surface mount caps myself in my workshop for a fraction of the cost of a replacement board.
See my other thread for more information.

Have you tried to contact ptscorp.com yet. Go to their web site and get their telephone number. They should be able to help you with a good hyper board. this might be your problem with what the set is doing now. Did you have this problem before you worked on the scan converter board?

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
