Help - Vision PM-4230 problem Can't Post

Hi all. I have a vision PM-4230 42" plasma that is a no worker. When I turn it on the power button goes from green to red. I press the button it goes on to green followed by a high pitched screeching noise then "click" back to red again - no display at all. It's a few years old now and it's sat like this for about 9 months so it conked only after a year and a bit. Just before it went wrong the picture was going a bit mental with hues of green all over the screen....then this.
I have popped the back off and had a good old nose around and after reading around some forums I in all my wisdom (hehe) have come to the conclusion that it's the power supply module thats knackered. There lives on this board a cap which although not looking blown is very very bulbous on top. It's a samyoung TDA 100V 1000µF (M) 105°C.

I am trying to find one of these but with no joy at all. The info I have is...
TV Make: Vision PM-4230
Part: PDP Power Module
SP-3000
SM TEC
Part No: 03H19176 ??? - I think its that but it's hand written on the board.

My biggest problem is that I live in a very very rural part of France. There is absolutely no chance of finding someone around here that is capable of repairing it and also it's a hefty old thing so it's not like I can post it off somewhere.

Any suggestions?
Tnx Brent.

bulging electrolytics generally are faulty so change it first and see what happens.any component supplier should have 1000mF 100v caps.

Tnx for that techchris.

I found some pictures of this board ion question at http://parts.discount-merchant.com/...s.php?itemid=1002083 and on this board too the cap in question has a bulge on top of it so maybe it's not that that's causing the problem. The cap in question is the light brown cap with the plastic cover on the top right of the board.

Am I right in assuming that this screeching noise that is definately coming from the power supply board is a faulty component on that board and not perhaps another faulty board in the tv causing the problem to appear here? lol a bit vague I know but I am just weighing up if it is worth the risk to try and get this board and replace it. That's an even bigger if as it's an American company and I dunno if they will even send to France.

Oh well one can but try.

Tnx Brent

very few plasmas are repaired to component level so if the boards are not available then you are stuffed!
