Hi I picked this TV up at work because it was going to be thrown out. I have been looking around the net and asking questions for weeks and learning in the process.
I have a decent understanding of electronics but not TV related experience and so loving the challenge. I must be mad but im sure some of you can relate.
It seams I have the dreaded relay clicking issue that could be linked to many different possible faults in the TV. Its how the TV protects itsself when there is an issue some where so I understand.
The only voltages I can find are the standby 5v lines x 2. These are 5v until I plug in the main board then its drops to 3.5v and few components get a little warm on the PSU board. One transistor and one diode. I have tested the diode and replaced the 2 capasitors here. As for the transistor im not sure (IC 301 a STR W6252 power IC)
I have currently decided something must be wrong on the 5vstandby lines of the main board but cant fine any scematics or training manuals with the PD92A EAX57566204 main board.
There is no stable AC detect just appears to pulse very quickly so I cannot read it with my DVM.
