Part needed for SVA Plasma set	Can't Post

I have (2) 42" Plasma sets, model ED4206 manufactured by SVA. I have diagnosed the problems with both, have one repaired and know exactly what part I need to get the second going.

The power supply board (manufactured by Samsung) had a blown MOSFET and power supply IC. The Infineon MOSFET (SPA11N80C3) I can get all day from Digikey, Arrow, etc. The control IC I'm having a hard time finding. In fact, according to the original manufacturer (Fuji Electric) it has been discontinued. Here's the part:

FA5531 8 pin DIP
Fuji Electric
(Google FA5531, and the first search result is the pdf)

The display in this unit is an LG PDP42V7

The Samsung Plasma Power Supply is labeled:

L42V7
Part # PSPF401801A

The IC is used in two places on the board, IC 5000, IC 7000

I will need (2) of these little buggers, as I used one from the board to fix the other set. I have socketed the board and have had both sets running for a week straight (not at the same time, as that would require a parallel universe).

Needless to say SVA America is no help, as they want to sell me a complete PS for about $480.00. I'd prefer to find a couple of 8 pin chips first.

Any help would be greatly appreciated.

Thanks

it seems SVA AMERICA is your last resort. Why don't you run the fixed one overtime and see how long it last? $480.00 may worth sacrificing.

Well it turns out I got the set going. I didn't have to pop for the $480 Power Supply Board either. I found what appears to be an equivalent part for the FA5531. ON Semiconductor has Quasi-Resonant power supply chips in the exact same form factor and pinout as the Fuji Electric part I couldn't get. I'd even go so far as to say that Fuji Electric copied the patented technology of ON's chip a little too closely and that led to it being discontinued so quickly. The part that worked is NCP1207P. Got it from DigiKey along with the MOSFET. The Plasma Set has been on now for 24 hours. I'll give it back to the customer in a few more days if it holds up!
