Urgent - power supply (board) for NEC 50" plasma

Hello everyone

I have the opportunity to purchase a 50" NEC plasma (model 50VP1, came out about 3-4 years ago) for really short money. However, there is a catch - the TV seems to have a bad power supply/board (shuts off after

15-30 minutes, then after it cools down starts again). The current owner got a quote for $1000 to replace the power board. While that seems a little high, I am wondering if there is a different route I can take - purchase the part myself (maybe from an NEC authorized dealer) and have a repair shop just put it in, maybe have the existing power supply fixed etc. Any suggestions, feedback on that?

Any info would be appreciated. You can email me at snipped-for-privacy@hotmail.com as well.

Thanks, Sergiu

The cost on the power board is something like $900 plus the $100 to install and perform the required voltage adjustments to specification.

Possilby, someone with the equipment and knowledge could find the intermittent issue on the board and repair it to component level.

With all the severely burned in or cracked plasma panels I've seen surely good used boards aren't too hard to come by?

Sounds like a thermal overload. Have you tried cleaning the dust and dirt from internal parts on the power supply, esp. heatsinked parts?

I haven't bought the TV yet, I am this close though, I will try cleaning the power supply, I guess it could be a vent or something. The owner supposedly brought it to AA Appliances in Boston (they are big, heard of them before and recommended by NEC) but they were awful. Not sure if they even thought of cleaning it.

Now, two questions:

- who would be able to perform board-level repairs - someone with knowledge of electronics, circuits or does it have to be someone with plasma TV experience. What I'm asking is, is this a matter of finding a short or something (apologies, as you can tell I am not very knowlegeable) or do they need to know more about TVs and such

- also, if all the specs are the same (power in and out, amps not sure what else), would any power board work or does it have to be specifically for that TV? The TV is fairly old so I am not sure if I can find a broken one (which would go for probably $300 - $500)?

Thanks everyone for all the replies, it's really helping

Actually, got a few more details about the defect - aparently the power board has a bad 70 volt line. Any ideas what that means, if it can be fixed or do I need a completely new power board? If there is need for a new power board what is the best route to get one - through the manufacturer (they do not support the model anymore), parts dealer etc? any concrete suggestions?

Thanks a lot guys, Sergiu
