Here is the info about repairing a hyperboard How To Fix Toshiba Rear Projection HDTV wavy lines

Most of these hyperboard are inter changeable.But must Check the 2 STK convergence ICS munbers on the ICS parts have the same printed #---?

Search for the audio amplifier - it's a chip with a radiator on it - the jack for the speakers should be close by.

jhinsincity: you dont need to be here, do you? the problem are the caps on the hyperboard, 10 -16v@ 10uf, rear access right hand green board, model 57hx81, the hyperboard must desoldered from main board. read the post on wavy lines,,

this is a very common problem in a lot of Toshiba sets of this type----bad caps(filter capacitors) on the "Hyper" board---it processes all signals in the set---it will start out where it clears up after warmup and as time goes by it will take longer and longer to clear up----the board is no longer available and the only way to repair is remove the one in the set and send it out for rebuild---most of the time this costs 3-4 hundred parts and labor(not worth doing)

I just did a repair on one of these. Check your picture-on-picture. If the the secondary picture is clear, chances are very good the problem is on the "hyper board". We d not replace the hyper board - we repair it. The board is very expensive and rarely, if ever, available. There are several parts in the module that need replaced, but these are definitely not user replaceable. They are very small surface mount components and even I have lifted a copper or trace or two doing these. It is tedious work but our repair bill was well below $300. It is also something I do not do in the home and taking it to the repair facility is a money saver. I did go to the home on this one and remove the board to the shop, however they only lived a few miles away so the service call was low priced. Hope this helps...

The board incased in metal directly behind the input board.It will be the first board you see after removing the input board.

Found this person on eBay who repairs the hyperboard for $75 quickly with very positive feedback.

I have the same problem and will probably send mine after the holidays.

It will cost about $300 to fix. The Hyperboard has to be replaced. I had it repaired over 2 years ago and it works great.

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.
