Wavy Lines which clear up after being on for 10 minutes - Toshiba 50H82

virticle lines left to right and takes a long time to warm up to see picture. clears a bit

If you have a normal picture with lines through it, or if the picture jumps, tears or rolls, you have a Hyper Board that is failing. The last I checked, the Hyper Board is not available from Toshiba and has not been available for a number of years.
I hope this helps,

Projection TV sets have two very common problems listed below.

Problem #1) Convergence


These sets need to have all three colors - RED - BLUE - GREEN - lined up correctly on the screen in order for the picture to look normal. This is called convergence.

When its out of alignment the video will look 3-D, wavy, distorted, etc. Most of the time you just need to adjust your convergence in the menu. If you cannot adjust it in the menu - then your convergence is broken and needs to be repaired. Convergence problems are very common on all Projection TV sets including Sony, Samsung,JVC,Philip Magnavox,Panasonic,Akai,Pioneer, Hitachi,Mitsubishi,Zenith and others.
You can get more information and a DIY convergenece repair kit with instructions from the link below.

Here are some of the most common problems with these sets...

*Screen Looks 3-D
*Colors wont align
*Screen may look distorted or warped
*No Audio/Video - TV Shuts down - May also make a constant chirping sound

Problem #2 - Another common problem is dull or washed out video.

Your set may have one or more of the following symptoms....

*Dull looking picture
*White looking picture
*Halos around objects
*Red/Orange looking picture

It needs the Scan Converter Module repaired or replaced. It usually has dry capacitors that need replacing

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)

sounds like the Hyper module as it can cause that type of symptom when the Capacitors are getting weak

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...

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.

this is a typical hyper module replacement job let a tech do it.
not for the do-it-yourself type.

Bad hyper board = can be repaired by a skilled,qualified tech...T.
