When I turn on my 50H82 it takes 10 to 15 minutes

When I turn on my Toshiba 50H82 it takes 10 to 15 minutes to "warm up" for a clear picture. Otherwise it has wavy lines & a great deal of distortion. Any suggestions?

    I have a 50H71 that would take about 15 minutes for the picture to settle down and even after that, it was still a bit shaky. The repair man came yesterday and replaced the hyper board and now it is back to perfect. Bit of a tricky job as the hyper board is saudered in. Total cost $370.00. $80.00 for the service call right off the bat. Still cheaper than a new T. V.

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 picture on our Toshiba 50H82 rear projection tv is shaky, any diy solutions for this?The picture will sometimes clear up after about 30 minutes. Can this be fixed? The sound is fine, it's just the...


Thats almost always caused by the surface mount capacitors which get weak on the hyper board. Hyper boards are going to be hard to find. But the capacitors can be replaced which will usually solve the issue. However it will require precise soldering skills to do the repair.

Wavy line or scrambled picture when l turn the tv on it takes 30mins for the picture to come in clear


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,

My Toshiba 50H82 television takes about 30 minutes to clear up and during that process, it shakes.It becomes clear but still has wavy lines at the top of the screen which is about 6 inches.


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

Toshiba 50H82 has wavy lines in screen for about


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)

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


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.

TV picture scrambled and getting worse


This can be a fault in the tuner, IF, or primary part of the video processing. With age and use some of the parts, and especialy capacitors, in these sets can become thermo sensitive and unstable.

To service these types of faults can be very time consuming. On top of this would be the cost of the parts.

Considering the age and type of set that you have, I would suggest that it is time to be looking for a new set.
