I have a Sony trinitron TV KV-27TS27 (about 15 years old). It was working fine last night, but this morning when I tried to turn it on, the on button makes the usual sound like it is turing on and I hear the usual crackling sound like the TV is turning on, but the TV screen remains dark. Does anyone know what the problem might be and what needs to be done to fix it? Is it something I can do myself or to I need to get a repairman?

The color signal consists of Red, Green and Blue. Those three colors, at various degrees, make all the other colors on your screen.
If you have a BRIGHT green screen it's best you don't operate your set. If it's just tinted green then there is a problem on the CRT (Cathode Ray Tube) drive board. Do check your "tint" setting and see if someone misadjusted it. If that isn't it then you need to have your set on an electronics bench and get an estimate for repair.
It must be connected with the color circuit of your tv, a board connected to back end of the tube. Could be dust, cob web or carbon deposit shorting a transistor. Popping noise if loud enough can be attributed to high voltage circuit fault and picture tube.
For the last week my TV has been going to a black screen for 10 seconds or so then the picture returns. It has been continual. Last night it stopped going to black screen, but now the standby light flashes 5 consecutive times and the color went haywire. A lot of red and everything that is suppose to be black is green.
I did a soft and hard reset with no success. What's wrong and is it worth fixing? Bought new in November 2002.
I have the same problem. Picture cuts out completely then back on. When I first turn it on, it does this constantly for about 15-20 mins, then about once every 30 mins or so.The sound is fine, but the picture just flashes on and off. The color is also starting to shift a lot and cannot be fixed by adjusting COLOR-BRIGHTNESS-PICTURE in the video control menu system. Nothing seems to correct this. I've even unplugged the TV over night to see if it needed some sort of reset. Model = KV-20FV12. Purchased in 2004 My connection is a direct cable connection - Comcast cable. Same problem persist while showing a DVD as well.
