MY Samsung DLP TV Has Green/Purple Lines

Vertical lines on Samsung LED TV PlayItHub Largest Videos Hub

Sounds like a problem with the Vertical Video Card.

Have fun finding one. If your TV is still under warranty... send your TV off for repair.

Either bad capcitors, or (if you're lucky) the color wheel needs lubed up. Probably bad caps.

Hi, was there a solution posted to this problem? I have the exact same problem and would really like to some help on. Thanks so much.

It is probably the main total assy needs to be replaced.

Time for a new TV... Unless your really really really attached to that TV your going to spend more money on it then its worth to try and troubleshoot and repair it. Most of the TV's that come across my bench for repair that have developed lines and color splotches go into the recycling dumpster, they just aren't worth the time to repair as it usually comes down to a bad board or components that just can't be obtained to repair it. What most people don't realize is that once a tv is a couple years old there just isn't service parts for them anymore. The manufacturer keeps parts available until the warranty period is up on a model then its done for.

This may be a mechanical or electronic problem that is dealing with the sync of the colour wheel. There is basicly no colour lock. This may be the replacement of the associated circuit board, or the motor assembly or the colour wheel.

The link below is describing about how DLP technology works. They are relating to a front projection type. With the rear screen type, the basic technology is very much the same for decoding the pictures from the TV signal.
