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 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 seems to take ages to turn on, the red on/off light flashes and then goes off completely and the screen stays blank. It then switches on again and after a few seconds/minutes will switch back off. Eventually it seems to warm up and stay on. On occasion it will take up to 10 minutes for the TV to warm up and switch on. Once on there is no problems. I have not tried fixing this as I feel it may well be a job for a qualified technician. Please advise if the TV is safe to use, and what's need

I have a Polaroid FLM 3772 that when it is turned on has a whinning/humming noise and after 5+ minutes it almost completely goes away. As if it quits once the TV is warmed up and just recently the screen will turn greenish with vertical lines sometimes. The line problem will go away if I unplug and replug in the Green video cable. Can anyone tell me what this is and is it something that can be repaired and if so what part(s) are needed and where can I get them. Thanks Bobby
The humming/whinning sound is from the power supply module and it will get worst (bad caps).\012The lines on the screen can be caused by poor DC from power supply, or failing T-CON board, main baord, or worst case the LCD panel.\012As you ...

My Pace TDC770d is turning on, then off over and over again, roughly 8 times per minute. When it's on, it shows a blue screen and says "loading.... bla bla bla..." then turns off immediately. I've tried unplugging the power to the box for 30 seconds at a time with no luck. This happens a lot. I think it's possessed. I need a priest or something.

About 8 months ago, every time I turned on the TV (SK-26H590D), only vertical lines would appears... almost like watercolor: green, orange, etc. However, you could hear the channels and change them as well... but still no picture at first. The the channel would come on after about 5-10 minutes. This has gone on since then. Almost as if the TV needs to "warm up." Today, only the vertical lines appeared but the tv never came on all day... just the voice. And the channels can be changed, but no pic

My TV is about 9 yrs. old. Lately, it seems to need to "warm up". The picture looks jagged or jumpy when first turned on, but improves after a few minutes. Can this be fixed?

TV turns itself off after about 5 minutes (green light remains on). I can turn off the TV and turn it back on immediately, however, the TV turns itself back off after a few minutes. It started turning off itself off after displaying harizontal shock waves like lines on the screen that got progressively worst. Now there is no line, just powers off. Once turn back on shows great for about 5 minutes then clicks off (no picture or sound) with green light still on.

Hello everyone, I am having an interesting issue with my 60vs810 recently and was wondering if some of you guys can help.
After the TV has been turned off for a while (about 4 hours or longer), when i turn it on, the screen is fuzzy for about 10 minutes until it is warmed up and then the picture stabilizes. It's hard to explain but it looks like the horizontal hold is shaking really bad. It does it on all of my inputs also.

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?

TV starts to make a loud frying noise. Have to turn it off, wait a few minutes and then turn it back on. When it comes on, it says something about having "instore display settings".
