Re: waves

If they are green, red and blue lines, you have a typical convergence problem that happens in almost every rear tube projection set ever made. There are two IC's that need replacing to correct your problem. If you do not know how to solder, unsolder, work on solid state electronics, you really should call out an experienced tech to assist you in this repair. These sets now a days have no user replaceable parts inside of them. A TV set as this one, should not be a place to experiment around inside of. Good Luck

I have a Panasonic Quintrix F TV. About 6 weeks ago the tv screen started displaying

Rule out the signal source by seeing if same issue when a DVD etc is used.

Usually a wave like motion from bottom to top is either signal related or a problem in the power supply (wave moves from bottom to top suggests that).

If not on rear inputs (A/V) it is not the power supply.

Model number is not indicated here and might be helpful.

The most likely cause is shorted convergence chips and possibly a few pico fuses.

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,Pioneer2_bing.gif Hitachi,Mitsubishi,Zenith and others.
You can get a convergenece repair kit with instructions from the links below.

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

Problem #1) Convergence

Yours may have one or more of the following symptoms...

*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

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

*Dull looking picture
*White looking picture

That symptoms are due to failure of convergence out ICs in your TV that will be replaced to get correct converge picture on front screen.

There are 2 big black IC mounted on big aluminum heat sink and number would be written on as STKxxx, these 2 ICs will be replaced.

If you want to repair TV by yourself then confirm model number of TV to provide you more info or call local tech to replace said ICs.
