Toshiba 57H82 problems

Is a common problem. Your hyperboard has failed. You can get a repair kit from www.TvRepairKits.com or buy a used hyperboard - but it will also fail someday unless it has been repaired with better parts than what the factory supplied.

Hi,
Your Toshiba TV has hyperboard inside and there are few electrolytic capacitors (may be 10) that need to be replaced.
If you are comfortable with soldering parts in PCB then go ahead or ask help to any friend that knows electronics stuff repair.
Let me know further query.
Thanks.

By the red being "off" I suspect you have a convergence problem and adjusting will bnot likely fix the problem. The convergence amps need to be replaced but if you email me I can send you the servoce manual... Just provide me with enough info in your mail, model number, because I get nearly 3000 emails a day and I won't likely remember what manual you're looking for...

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...

Heres your link for the capacitors http://www.mcminone.com/search.asp?keyword=surface+mount+capacitors&btnSubmit.x=8&btnSubmit.y=7&btnSubmit=GO Loads of info here about the board http://www.techlore.com/forum/thread/15237/Toshiba--Model4283--picture-is-zig-zag./ Good Luck

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
