TV is on, Picture and Sound is fine then all of a Sudden the screen goes Black but the Sound is still there. It will stay Black for 20 to 30 seconds and then comes back on. Repeats this Pattern every 20 to 30 Minutes.
Since my last posted my problem has changed. My Picture is coming and going every few seconds. Screen goes black. Picture color is no longer good, its greenish now. I have notice there is a light that flashes when the screen goes black, the light is located next to the power button. Over the light it says "Stand by/Timer". This is a Model KV-32FS100
Thank You for any help,

My Sony KV-32FS10 has sound but no picture. The red 'stand by/stereo' light on the bottom of the TV itself (not screen) is blinking off and on. Please help! THANK YOU!!!

Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
This is inverter or backlighting problem. Can you try switching it on and off quickly for a couple of times and tell me if these '2 seconds' get any longer'. If picture stays longer and longer before shutting down, one lamp needs replaced-if not, please replace inverter board
This should be a quick fix. Try resoldering the vertical IC. This is a small flat IC attached to a heat sink with about 11 pins. It should be marked LA7837 or something similar. That should resolve the problem.
All symptoms in your TV shows that you need to replace its Lamp as it has been consumed its life hours and TV requires new lamp. Lamp can be obtained from Sony Website. Price is $200, Hope this info will help you to enjoy your Sony TV in coming days.
Sounds like the CRTs are going into protective blanking due to the vertical output ic needing to be resolderd. Try resoldering the vertical IC that may possibly fix the issue.
The most common problem (I have fixed lots) is the Vertical amplifier has developed a loose connection. It probably just needs resoldering. As things expand it makes and looses connection you picture goes in and out. The vertical chip is a large black chip that gets hot, over time it degrades the solder until a connection is damaged. Most newer sets have a protection circuit that senses the lack of height, and shuts down the picture tube to save it. When the picture dropped to a line on older TVs and left that way too long it would burn a line into the face of the picture tube. You then had to have the picture tube replaced along with the vertical amp. it's kinda like a screensaver for your TV.
