The TV turns on but takes 3 minutes 20 seconds to get the blue screen (repeatable time). The screen says ‘no signal'. It takes an additional 4 minutes to respond to any side panel or remote control commands. After that the TV works well, but if the power is turned off the sequence repeats. It loses all programmed channel memory and need to repeat the channel scan process.
I have replaced many of the electrolytic capacitors on the power supply module. I identified bad ones with an ESR meter. I also checked values on bulged capacitors and replaced them as well. The problem still was there after replacing about 12 capacitors on that board. I then pulled the main board and started in on those capacitors. I replaced 45 on that board but am sure there are more. I was hoping by chance I would have hit the responsible circuit with all the bad capacitors replaced so far but the problem remains. Any thoughts?
Thanks
