Television picture has no picture it just displays a multi colored set of lines almost like a plaidlook u can kind of makeout nfaces like they are in the background before this it would get a six inch black line that would move from left to about the center and back

This is usually the TCON board or ribbon that connects it to the display panel. If it is a LCD and not a plasma set.

Does the menu function display the same lines? What kind of cables are using ? (HDMI, Component vid, S-video, co-ax)
Were you as tenacious checking all cables/connections as you were the electronics? Lets rule out this all too often over-looked possibility.
Do you still get the lines with nothing connected to the TV? (no source connected)

If its 10 years old boards and or parts will likely not be available--average life on Plasma and LCD sets is 3-5 years.

I would retire it--recycle it and buy a new set.

kindly check if on the BIOS you can still see those lines...if it is still there obviously it is a screen issue

your flat panel set was hit by something causing the pixel lines. from physical force. sorry to tell you this but the display panel has to be replaced. call a service shop for verification.

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

Hi! the problem you have describe denotes that you have a defective positive thermistor. the positive thermistor is the one responsible in turning on the degaussing coil to align the stray color on the picture tube during start-up.

The Q-Box could cause this problem.
Hope this helps,
