I have a Samsung DLP TV (model HLT5076S). When you turn it on there is no picture for several minutes (5-10 minutes) and then there is no sound once the picture comes on. You need to turn the TV back off & then restart it to get both picture and sound. Sometimes you need to do this several times before the TV turns on, you hear a click, and then you get picture & sound. It seems like it is waiting for something to warm up? The problem is not the bulb (fairly new) or with the electrical outl

The TV turns on and shows a picture that you can watch and within 10 minutes the TV loses its picture, however, the light is still green. If you turn the TV off you can get the picture to come back after you wait like 20 minutes or so but the TV will lose the picture again in 10 minutes or so. Any suggestions?

My LG 32LC7D TV takes 20 - 30 minutes for the picture and sound to appear. I have done all the basics to investigate to no avail. I do know that if I turn it off and then straight back on after this 20 - 30 minute waiting period it does turn on immediately. I suspect it needs to warm up somehow and I am thinking it won't be cheap to fix. Any help is appreciated.
I would start with the power supply, check the condition of the capacitors. Look for any with bulged tops. ...

As I am watching TV, after an hour or so, I start getting horizontal static running across the screen....within minutes if gets worse, i turn off the tv, wait awhile and turn it back on and it's ok......sometime it will be ok for several hours, other times much less
It seems that it may be over heating. If you are knowledgeable about these things you can take it apart and dust out the insides. That may help. Otherwise one of the system boards are failing. Then you would need to take it to a TV tech to have it ...

I have a Sony Bravia KDL52W5100. When I turn on the tv sometimes everything is fine but other times there is no pic only rainbow stripes. I have to turn off and on the tv several times or unplug the tv to get a picture. I have tried rebooting the entire system it worked fine for couple of hours then the problem came back. Sometimes while I am watching a show the screen will gradually change into the rainbow stripe. Do I need to replace my screen and is it worth it?
Check all the flat cable connections from T'Con board to panel, for loose connections. Re-seat them all. ...

No sound at all on Mitsubishi LT-52151. Fixed before by unplugging, waiting 30 seconds, plugging back in. Was occurring more and more often to the point of having to do this every time I would turn it on. Have let it go several minutes and tried plugging it back in. Nothing getting the sound back this time.
Just fixed this on my TV today! (after 2 months of the sound intermittently failing to turn on and failing completely yesterday) Go to Mitsubishi-tv.com. Go to support. Enter your model number. You will be directed to the documentation for your model ...

I have Vizio XVT3D474SV I bought a year ago, in the last week while watching TV, the screen start to flash, display becaome white with 3 black lines and after a while it becomes black (the all time the sound stay as normal). while looking inside I see the backlight flashing till the screen becomes dark (than I do not see any light inside). After turning off and ON the TV several times I get back normal pictures but the same phenomenon comes back in few minutes.
I checked all 8 micro fuses I have
When the picture is dark, show a torch light on the screen from a safe distance. If you can see the picture, the backlight is the problem. Anyhow, it is better to show it to a qualified service technician. ...

It could be that there isn't enough airflow, and you've overheated your TV and broken it. By letting it run, you may be reheating the circuits and letting the solder flow, temporarily fixing your problem ...

I have a Phillips 42PF9966/37 Ambiant Plasma TV. This TV is about 8 years old. When you first turn the TV on the picture is fine and you have sound. After anywhere between 5 and 15 minutes of being on you will start to get green and red dots appearing accross the picture where images used to be. This continues until the entire screen is basically green and then it starts to turn black. At this point you really can't see any images on the picture. Sometimes you can turn it off for a cou

I have a 22 inch AOC Envision LCD TV. When I first turn it on, only the top half of the screen displays picture while the bottom half is a gray/black color. If I wait about ten minutes or if I tap on the back of the TV, the picture is completely restored and I can watch everything just fine. However, it is pretty annoying to wait for the picture to come back. Since the picture does come back after a while and looks fine, I don't think I have a broken backlight or anything like that. Also, becaus
