My tv, and also my mother in law's, which were both bought at the same time 6 years ago, started turning off by themselves. They won't turn back on immidiatly but if I wait a few minutes They will come back on. Not for long though, about 10 or 20 seconds or so. Seem's like the longer I leave the tv off the longer it will go without shutting down. Any suggestions? The TV'S are not at the same residence.

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.

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 am having problems with my Sony Bravia LCD tv model KDL-32L4010. When first turned on the picture looks good for about 30 seconds, then develops white vertical lines. After about 3 minutes, the lines fade slightly and the picture becomes more washed out. There is about 1/2 inch of good picture at the top. After, about 12 minutes the picture is no longer washed out but seem to have low definition. After about 20 minutes the picture begins to jitter vertically creating a double image. The menu

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. After about 10 minutes, the TV seems to be warmed up and it works

I have an LG 47LB5D LCD Tv that shuts off after approximately 30 minutes running time. It will cycle back on after a few minutes, so I assumed it was the power control board; replaced it but Tv still shuts down. It does seem to stay on longer, sometimes up to 2 hours without shutting down. When it shuts off, you can hear a click as if a switch threw. This started after a lightening storm but not sure if we had a strike.

My screen won't come on, however the blue light does come on to show it has power. Sometimes the screen just stays black, other times it seems like it's going to turn on but doesn't, meaning the screen lightens a little but it never fully comes on. This happens intermittently; when I unplug the power source for a small amount of time it sometimes fixes the problem and the screen comes on, however it often takes several tries. Periodically it just comes on right away. Also the remote frequently s

I have an Acer AL2416W monitor which is playing up. When switched on it gets very bright after around 20sec and develops bright vertical lines. The images is frozen and the whole monitor goes dark (but backlight still on) within a minute. Seems like the t-con board?
