F5300: not re-turning ON immediately

I have a PN64F5300 (PN64F5300FXZC, about 4 years old). I already replaced its Power Supply 1 year ago (the TV would just shut down on its own).

The TV is working fine in terms of pic quality, but when I turn it OFF, I need to wait a bit before I can turn it ON again (5-10 min usually do), otherwise
the TV will just show a slowly blinking red light but do nothing (can't hear the usual "click" relay sound)



What could be the problem ?

This sounds exactly like the ceramic capacitors issue:

The fix is to replace the Y-sustain board, if you can find one to replace it with. Or, replace certain ceramic capacitors on that board. I fixed my F8500 for $50 by getting a local electronics repair expert to replace 3 ceramic caps with new ones that I got from Mouser. Other owners have done it themselves, but I was not up to that level of precision soldering.


All the details are in the referenced thread.

Sounds a bit like the 7-blinking LED problems on the Philips plasmas that was fixed by replacing 2 capacitors that cost about $10 total.

They would blow their tops and ooze some black gunk when they were done. The lifespan of the OEM capacitors was about 7,000 hours and most of those blown were for TV's that had just under that amount of usage. The ON-OFF electrical surge wears them out I believe.
