Black wave like line on the tv screen

I just bought a 50" RCA DLP tv. It has a black wave like line that goes across the whole bottom part of the screen. What is this and can I fix it?

Sounds like the vertical area like Output, but I would look for bad caps first and resistors. In this area

I did some reading on this. They said its caused by a faulty DMD board. I understand it's costly... around $700 to replace. Still looking for a cheaper avenue...

Good Day, LDS also;
You may have a poor seated cable connector. Unplug TV from A/C, remove back look for a large black connector. It connects between the Main Digital Module and the Drive PWB. Re-insert both ends several times to make better contact, use contact cleaner if have but not always needed. Good Luck, big IRISH.

do you have a cordless phone placed nearby?
i just had that problem, and realised it was because of the phone's frequency (scary!). i move the phone/base away from the tv, and it's fine now.

Samsung rear projection tv have vertical black linens up and on tv

you have a bad dmd module and it cost around $750-$800
Happend, because a bad soldering connections in that module. Lines will come on and off. Probably 1 day will stay on. For last 2-3 years im seen that only on hlm and hln series. Probably
happens on other models. but, i never seen that.
Is not that hard to replace that module. You have to remove 2 screws from left side and 1 screw from bottom righ side of module and 4 of them
from around dlp unit unpulg all cables ( i think
3 cables ) that it. Same way install new one in.
but you will need to adjust a module position to get picture to fill whole screen.
