Hi all,
I picked up an Insignia NS-PSDP42 TV.
Symptom: Push power switch, relay clicks, then 3 seconds later it
unclicks.
I seem to be missing voltages out of the power supply PCB, from what
little info I have gleaned off the net so far.
I don't want to buy a new power supply PCB, I'd rather replace
defective components.
Does anyone have a schematic or experience with this problem.
I see a common problem are 4 bad caps, but mine look and test good.
Darn it!

Thanks, Mikek


You didn't say whether you tested ESR or capacitance. Some electrolytics
need to be ultra-low ESR types so the reading might look good enough but
isn't.

In the UK, some consumer equipment parts sellers offer PSU refurb kits
(usually mostly the electrolytics known to cause trouble) If you're trading
and charging the going rate it worth the price of a refurb kit to reduce the
chances of a return.
