I have a Samsung DLP that has squiggly lines all over. They almost look like veins everywhere. They appear all time all over the screen. They are not vertical or hosizontal. Close ups are worse. Help!

SOURCE: RCA DLP/HDTV Vertical Lines

This is djb1 who commented above on the vertical lines that have gotten progessively worse. I may have found a potential solution. I unplugged the TV, took the back door off where you replace the lamp, took the lamp out, changed our vacuum from a vacuum to a powerful blower and blew ALL visable dust off anywhere that I could. I paid special attention to the heavy dust that was on the TV blower fan blades and around the mirror. I also held the blower on the outside of the TV on the vents around the lamp door.

After I plugged the TV back in, the lines have disappeared. We watched TV last night for about 2 more hours and the vertical lines never came back. So far this morning, the lines have not come back and it has been a couple hours as well.

It's worth a try. The free solution may be as simple as clearing out all dust. LET'S HOPE IT'S A PERMANENT SOLUTION!!

Vertical white lines appear on the screen. Samsung provides the following information but doesn't say what circuitry they are referring to. Samsung says: DLP TV: I Have Vertical White Lines...


That answer I agree makes no sense.

Most of these sets have NO vertical hold and if did it will not cause the lines.

A brief educated guess:

Set has a main board that communicates and controls the screen--tests for that are not simple (checking waveforms with a scope and signal generator).

The model indicated here is a DLP that uses a lamp (let me know if model listed is not the one you have).

In DLP sets aside from main/digital board you also have a optical light engine---it processes all signal in and out to the screen.

Optical engines do fail and cause some simple and some complicated picture issues.

Some will even cause the set to "lock up" with a picture or strange looking screen---clue to this is you have to shut the set off by pulling the power cord.

The set may be old enough they do not really want to help you or even talk about it.

My samsung 55" DLP television


I looked up how to fix red horizontal lines on a Philips flat-screen tv. It turns out it needed the Y buffer upper replaced. I am not sure if this problem would be similar but it might help. I am also searching how to fix a fuzzy screen on a DLP tv. Hope you find what you need.
