Re: 50h821

The tech repaired my television yesterday! It took him over an hour. He says the wavy picture, especially at start-up, is a normal problem causes by standard usage. He replaced the trasister board. He removed the back of the set and used a hot gun to remove and then replace the items. This was not a Do-it-yourself job. Unfortunately the Tech took the papers with him and I can't recall all of the part numbers.

Re: 50h821

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.

My 57h82 picture has picture noise in form of small jagged/wavy lines at edge of objects - particularly noticable for text or numbers. This appears on all channels and with all input sources. How to fix?

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

Toshiba 42H82, no sound after fixing hyperboard.

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

They are just little box reservoirs. Heat them up and pull it out when hot. Heat it up again and set the caps in the hot solder box.

I suspect that it won't play any source that uses progressive scanning. The likely problem is the hyperboard or scaler board. This component allows the TV to switch from sandard definition TV to HD. Typically, the hyperboard will cause shaking and wiggly images especialy noticeable at the top of the screen. It will generally work better the longer its on. Expect to spend $400-500 to resolve this.

Repairman for your TV yet?

Actually I found quite a bit of info regarding the problem and confirming that it has to be the caps on the hyperboard as hdtvman was mentionning.
I've bought the caps for less then $3, and will give a try at replacing them probably next weekend. I have nothing to loose as it's getting worse day by day now. If I screw up I can alway order the hyperboard from PTS...
