When I turn my set on it works just fine for about 5 minutes. Then I loose my picture (screen goes black) and the sound goes also. If I leave it on a get an occasional flash of light at the top of the screen and occasional sound comming throuht. If I sut it off and come back in a hour or so it come right back on for a few minutes.
Thanks for the help
Yes your set is overheating for some reason. If it is out of warranty and you feel comfortable taking it apart, get to the inside and use a compressor to blow it all out. It is very possible that it could be very dirty. If there is alot of dust all over everything it may keep it from cooling like it should. Just a hunch. I have seen it be4.
Other wise take it to a dealer and let them find why it is overheating after it has been over for a few minutes.
Try putting a fan directly on it after cleaning it and see if that helps, if you dont want to spend the money.

Re: Sony KV-32S25 loss of picture and sound
The set might have loose conections in the horizontal drive circuit and other overheated places in the power supply,dont use the set like that or it wii die completly and it will be more expensive.Call a technician so he can resoldered all the bad and questionable solder conections.Be safe and let a proffessional do it.Good day.

Your TVs Base card socket, that is the socket connected to the base of the picture tube is loose. Just unplug it and replug again for tow or three times. Please note for any loose sodering occurs to the pins of the socket and the video output transistors fitted on the picture tube base card. This should rectify the problem.
The key here is the standby light flashing. It should be flashing in a repeated count of flashes with a pause inbetween. Count the blinks and report that number here. This is a diagnostic code indicating the circuit that is having a problem. Armed with that info, we should be able to give you an idea of the problem and its solution.
I have seen this flashing before, this could be an indication that the picture tube is weak, what happens is that if the white balance is off there is a circuit called akb it monitors the kathode of each gun and if they are not in balance it will attempt to balance it out. if it can't the picture will begin to flash, sometimes in some models the power light will blink 5 times. On some models the power light will only flash if the tv gives up trying to compinsate for white balance and shuts off compeletely. If you see the tv shutting off with 5 blinks then you know for sure it is time for a new set.
You have a blown fuse. It should be a GMA7 amp or a 5 amp. You could try to replace it and see if your TV works again. If it blows the fuse again, then there is something shorted causing the fuse to blow. Then call a good TV Tech.
the problem there is a loose connection on the board,you said that you smacked the right side of the tv and it goes normal.there are parts that should be resolder on the board in order to back into normal operation.
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.
This is a simple and common problem. The solder joints on the vertical output IC have cracked loose. I actually did a housecall on the exact same set with the exact same symptoms this morning! A good tech will resolder the pins of the vertical output IC and all other major solder joints on the main board and the set will play fine.
