no worries. i got the answer from someone with the same problem on another forum just took a little bit of digging, i wouldn't be able for advanced electronics...

ok thanks for the help here. /s

For anyone that sees this message i fixed it by replacing IC905.

Hi,
I am new to this forum and have searched for some answers with problems similar to mine.
Philips TV powers on as normal for about a minute or less then click and no power at all not even standby light. If i disconnect from mains and reconnect it will power on again but for a shorter time. Once i leave it disconnected from main for a longer time it will power on for a longer period the next time.

It sounds like a power supply issue?

I have the board out and want to run some tests. Not sure what i should be doing but i put a 1k resistor across SB and +5v...
