Very likely it has bad solder connections on the vertical output IC. Or the IC could be bad and needs to be replaced.

Vertical ghost lines about a 1/2'' apart. Our cable provider changed out the DVR box and rebooted the system and the problem still exist. What is the fix??


The tuner of the TV may be at fault.To bypass/test if the fault is with the TV try hooking up the DVR using audio video cables through video 1 or 2 of TV rather than standard cable through channel 3or(4).

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

Pull off the back pressboard. At the bottom left hand corner is the power cord that attaches to the power supply board. There is a white plug that attaches directly to the power cord. With the TV power off, pull this white plug up to disconnect. Then push it back in. Then plug your TV back in and press the power button on the front of the TV. I just did this and it is working fine.

If you have audio and no video then something is shutting you High Voltage down. It could be many things. Convergence amps(color problem before shutdown) Vertical problems. Bad caps on 200V line.

Possible bad solder connections in convergence circuit or vertical deflection circuit. This happens in alot of equipment. After warm up, expansion of joint pulls connections loose. Recommend not running like this, could cause component failure.
