How can I fix my Samsung PS43F4500 not turning On
My Samsung ps43f4500 it's not turning on when I switch it on. Only red light blinks and sometimes the red light will disappear but nothing showing on the TV. And when it turns on it just watch for a few minute then picture disappear but sound will be playing
Guys here is my current situation. As I checked my voltages, I found out that all other voltages are Ok but the Va and VS voltages are normal jus for a few seconds after I switched my TV On ( the picture is actually showing for those few seconds sometimes but not always), then the voltage is starting to drop gradually till it's lower than 10volts.
Is that normal or not, if not how best vmcan I troubleshoot the Va, VS voltage fluctuations and what might be the cause of the problem?

neither one of those answers are correct - this is a plasma tv. The set is shutting down most likely due to protection circuit. Buffers may have a short on them. short main board pin 3-4 and install jumper on PS_ON to ground. plug set in - test pattern should be displayed on screen. If test pattern stays on - main board is bad. If no pattern buffers, bad YSUS board, bad PWB most likely
