I have a sony KP-53S25 that only stays in standby, and will not power up. When I plug it in, it sounds like a relay energizes, and a piece flashes. I'm not sure what that piece is, but I thought the schematic symbol looked like a cap. It does the same thing when I push the power switch to on. Any help would be greatly appreciated.

It was a neon lamp instead of a cap. I figured out it was going into protect mode, the fault was making the relays not stay on in the power supply. I checked over, and replace the HOT, although from forgetting to set my meter to the correct setting, I replace a good HOT. I finally took it in to a shop, and so far they are telling me that a few transistors are bad. I should know more on it soon. Thanks a bunch though!

I got this Sony TV for free and got (1) - the middle tube out of the 3 tubes replaced. After a week of using the pic became blurry on the right side of screen- left as we looking at the TV. The image appears with shadow only on one side of the screen; the rest of screen is fine. In case of an alphabetical letters the letters have shadow. The TV repairman said that he need the remote control to fix the problem. I wonder what is the exact cause of the problem. Anybody know solution to this please advise.

Very appreciated

My sony KP-53S25 TV randomly began doing this same thing. I turn it on and it just flashes on standby. We had a repair man come in and he suggested that he needs to fix the Arrow transformer. I would rather buy this part but can't find any place that can even quote me a price.
Question Any help?

I have a Sony KP 48v75 that flashes the standby light continuosly when plugged in AND when I pwr it up there is no picture and a burning smell. One day I turned it on and heard a strange sound and saw a blue color on the screen and then it went dead. Now as I stated above the standby light just flashes... Would this be related to the "convergence chips." CAN SOMEONE PLEASE HELP!!!
