If it says "searching for satellite" the problem is in your satellite receiver, not the TV. The TV is working. Its showing you the signal coming from the sat box. The sat box is the tuner and is responsible for the sat signal. The "searching for satellite" is a common problem after lightening issues. If you have multiple sat boxes, then swap this one with another that you know works. If this is your only box, call your provider as it means the dish LNB or the sat box was damaged by the lightening. Also have the wiring checked for bad grounds due to an improper install.

Take it to a service center. There's a problem you can't fix.

Hi Igor, This is happening due to the lose or bad contacts in the LCD panel. Fixing this kind of troubles is a highly risky and delicate job. If you are not a practising technician, please let some good Technician do it. Good luck.

Take it back to the store its obviously defective

I'm not a repairman, but I do know that a lot of sudden power-offs happen due to overheating. If an electronic device gets too hot, it has a auto shut off function that kicks in. Try unplugging it for 10-30 minutes and then try it. If its plugged into a surge protector, try plugging it directly into the wall outlet.

Sounds like mine I replaced the Bridge Inverters ( easy job ) , and worked great after that. I got mine from Shop Jimmy dot com paid $85 cheap fix not like $300 - 500 ! you may pay for repair man.

Lines like that are almost always a bad LCD Panel, but just to test...Bring up an onscreen display (setup menu, volume bar, etc.) that originates from the TV ITSELF, not your cable, satellite, etc. You need something that intersects the area of the screen where the lines are.1) If the lines are through the onscreen items as well, then it is a problem with the LCD panel. It sounds like you are fairly comfortable inside the set. First try to re-seat the ribbon cable(s) inside that are attached to the main board, insuring they are secured properly. See if that clears up your problem. If not, it's time for a new set.2) If the onscreen items are OK, and it only affects the input source (tuner, HDMI, etc.) then it is most likely the main board that is having the problem. Replace that and you should be good to go.
