Anyone had one of these in recently? Its not long out of guarantee, its stuck in standby. Flashing standby indicator. Any stock faults before I delve in there?
Thanks
Bill

Just had a quick look at it now, its the Vestel 17pw26-4, usual culprits check ok, but I'm a bit suspicious of Q828, can't find much about it, can anyone identify it ? No bulging caps and no sign of blow up.

Hi looking at pdf its a 10L60CFP

I've substituted the PSU board with a known good vestel 17pw26-3 from another 32" set, the only difference is the -3 version has no socket for the switch. The set came on fine, so its definitely the PSU at fault.
The usual uf5404 fast recovery diode checks ok, but I need to substitute it with a new one, as it may be leaky. I've also replaced the 33uf 63v electrolytic c801, to no avail.
Anyone any ideas?
Bill

UF5404 replaced no change, standby light flashing continuously. There is no sign of anything obvious.
