    After moving to a new house, out Samsung dlp tv turns off whenever it feels like it. Sometimes it stays on for hours, other times, it seems mostly in the daytime, it keeps shutting down over and over.



    I just read in another area of this site that the light and cooling fans get dusty and that can cause heat to build up, shutting the tv off. I'm going to try removing them and blowing everything out with canned air, as they suggest. They caution you to hold the fan blades as you blow air so it doesn't spin faster than it's supposed to. Hopefully this will eliminate the problem

You will find that this problem is a mains filter capacitor in the power supply.
You can change this yourself or bring it to me

Turned itself off. I turned it back on and the green power light blinks for awhile then blinks red for awhile.no picture or sound


Get rid of this TV. Had one and replaced the bulb and light engine many times. Just buy a Samsung or Vizio 50+ inch instead and be very happy. Those Panasonic projection TV's were terrible. You will find a 50 inch Vizio for around $500 bucks and it will blow your mind how great the picture looks.

I have a sony plasma 50 inch i am getting a few lines in the middle of screen and they are there when i turn on the tv even though i do not have the cable on


Are they very thin vertical lines? If so, you most likely have a bad plasma panel. A picture would help to confirm the diagnosis

Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

Check your cables and TV input settings.  Can you get to the on screen menu?  Does anything appear on the screen when the tv is on?

I have a 50 inch big screen hdtv and i am moving i want to know can i lay my tv down flat?


Yes you can lay it down flat on its screen just make sure it is padded so the screen doesnt get scratched. I transport projection units this way all the time even DLPs however do not transport LCD or plasma units in this manner as thats not recomended.
