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
This is because the CRT that is the cathode tube ray oscillator is taking time to warm up ...

Hi just wondering if you can suggest a repair for my LG42PC1DV-AA. We have had the TV for 4 1/2 years. Last week when my daughter was watching it there was a loud crack and the screen went blank. After I let the TV cool down I turned it back on and the sound is good but the picture takes a few minutes to come onto the screen. It has a lot of Black lines I guess they are pixles that slowly dissapear and reveal a somewhat grainy and washed out picture. Is it worth getting looked at? Thanks Pete
The loud crack sound you heard may be due to a capacitor exploding, look for phisical damage and replace the component with and equal or better component of the same value,,,good luck ...

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 ...

After about 30 minutes of turning on my LG TV 32 there is a loud whip cracking like sound. The tv screen then normally turns pink but sometimes gets the picture back and the whip cracking sound keeps happening. It seems to me that there may be an overheating problem as it is okay when I leave it turned off for about an hour but it keeps on happening again. PLEASE HELP ME.

I have a ten year old 37" Sony XBR TV that works fine until you turn it off and then go to turn it back on. The picture does not come back, but sound does. The only way to solve this is leave it off for 30-45 minutes, although this time period seems to be getting longer. Any suggestions would be greatly appreciated. Thank you.

That is a plasma tv,Check the main power supply board for evidence of distorted or visibly swollen capacitors.You should have some electronics skill before attempting to repair that sort of problem because it involves solder work to replace the defec ...

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. ...

I have a Samsung LCD TV - Model number LE37B679, which is great, but I'm having and issue with it.
I can be watching ok for a while and then the picture goes & I'm left with a black screen. The sound remains.
I find I have to turn the power off for 30 minutes or so then I get the picture back.
Does anyone have any idea as to what might be wrong. I read something about a T-CON Video board issue, but I'm not technically expert enough to know if this is a red herring or not.

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.
Check and make sure your fans are working and there is sufficiant cooling to the back of the set. Sounds like it is overheating and going into protection mode. ...

I have a Samsung 46 LED 3D 200hz tv. Normally the tv is fine but lately the tv, after a hour or more of viwing, tends to lose signal. Often it starts off with the sound going and then I will lose the picture. I don't think it's loose cables. I often turn the tv off for a few minutes and then turn it back on again. The sounf and picture are fine again, but then I lose sound and picture a few seconds or minutes later.

The picture will come on when you first turn it on but after 15 minutes or so it fades away. The sound still comes out but no picture. Sometimes it will come back on on its own after a while and then go out again. If you turn it back off for 15 minutes or so it usually comes back on. We already bought a new tv and that one works fine so its not the cable box but I would like to put the old tv in my room.

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?

Hi, I have a Philips 42PFL7422D/37. Lately when I turn it on I get sound and no picture. If I unplug it let it sit, and plug it back in (sometime it takes several attempts) it will come on. Is it the power supply or the inverter?

The fact that the TV comes on tells me that more than likely the surge came on through the video cable. Without looking at the TV sounds like a main board issue. I recommend having a qualified technician check it out. ...
