I have a PN60E350A, plasma television. It started to not come on. I had to cycle through the sources to get it to come on. After a while that stopped working. Now it won't come on. I see the off light blinking when I push the remote button. I leave it on for about ten minutes, come back and cycle the source and it turns on. Weird. Once its on, its good

Fault with the main power supply regulator board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. 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 power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time.
I opened up the television to inspect for burnt out capacitors, found none. Put the TV back together and read the user manual where the troubleshoot mentioned no source from cable box. I changed the start sequence of the components where the cable box was first the av receiver second and thirdly the TV. First try the TV didn't turn on. The power light blinked six time and nothing. Turned TV of and on, this time it blinked and came on. I had it like that for another week. Now its back to doing the same. It's not coming on. I ordered a power supply from Jimmy's today. We'll see what comes of it when installed.
Update: I got a call from Samsung to tell me they were sending out a tech. I canceled order from Jimmy's (my credit card hasn't been refunded. Separate issue). The tech tells me it's the Y board. He replaced it and all seems to be good. I have a pic of it but don't know how to load. It's three separate boards joined together. One can find them on the left side of the television.
