This really depends on the make and model of the TV you are referring to. More than likely one or both of two things are happening. 1) There is a fan out causing the TV to get too hot and a safety switch is shutting it down to protect the TV from further damage. Or. 20 there is a bad safety switch telling the TV has an issue when it really does not. Another thing that could be going on .... It seems modern TVs have a tendency to burn out capacitors and bad capacitors will cause this behavior as well.

Your best bet is to use Google to search for common problems with your specific brand and model of TV. Also look for flashing lights on the front of the TV that may be blinking in patterns, these patterns may tell you what the problem is. ie; 3 blinks bad fan or 4 blinks bulb not seated properly etc.

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.

Takes about 5 minutes for picture to appear... Then every one to two minutes the picture disappears. It comes back on for 1 - 2 minutes then repeats. When set if first turned on, the stereo/stand-by light (red) flashes on/off until just before picture first appears .if your tv is very old than it might be due to crt getting weak crt base loose loose contact in power supply thanks
