Pioneer pdp-42a3hd

[rick_me24]

hello all. So I've had this tv for my kids playroom for many years (since 2006) and has worked flawlessly until last week. My son played Xbox and turned it off and went to bed. Next day it would not power on. No storms in my area during this time. I had it on a surge but in a re-shuffle of cables it got plugged into the wall so I know that is what I get I suppose by not paying attention. Anyhow, thought I would attempt to fix it. I opened it up and replaced four 8 amp fuses but no effect. No standby light or any power whatsoever. Didn't see any bulging caps. Power supply board maybe? Is this tv worth me trying a repair?

If you have a meter you should start taking measurements of the pins on the power supply board. Check first if this set has a Trap Switch before powering it up with the back off.

Re: Pioneer pdp-42a3hd

I didn't see a trap switch and some digging didn't uncover anything. What readings should I be getting on the pins?

Good to hear was it the pin on the motherboard or on the psu, could be a bad epprom or the motherboard isn't telling the psu to start, wish I could of seen that you responded to my comment would of loved to of helped.
