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 ?
