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,

How do I fix wavy lines on Hauppauge Wintv hvr950q?


Are they wavy lines throughout the picture or are they just wavy on the side? Waving picture is usually caused by poor power supply filtering. Wavy lines throughout the picture are caused by interference. Try moving the device away from the computer with an extension USB cable it may be picking up interference from the surrounding electronic devices. It could also be defective.

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

53h71 toshiba projection TV with noise in picture


The problem you have is on the hyper module located behind the rear input panel. Inside the shield there are about 6 or 7 10mf/16v surface mounted capacitors. Replace them and your problem will be history. As for the shop that did the repair they owe you a call back to do it right. However, request that you get a different tech to come out. Do not attempt the repair yourself, it involves excellent soldering skills and parts removal. Good luck

on the signal board replace the caps by the 5/9 volt regulators. c2p04 is the main culprit. 6 caps in total can be changed. I believe c2p05 also.

Scrambling for first 15 mins


That is the exact problem I am currently having with my toshiba 50 in. I did some reading and it sounds like there is a temperature drift across one of the capacitors on the board and it takes longer and longer to warm up. Havent fixed it yet...
