Akai 4290 power board

My akai 4290 has a power board aa98-00198aa that just went out and I can't find a repair part anywhere. Akai says they don't make that part any more. IEverthing inside is actually made by Samsung. Do you know how I can repair my TV?

Yes, I'm sure the board is bad. I had the TV checked out by a local TV repair shop. I also opened the thing up to see if I could do anything with it and it's obvious that this is the board that has bitten the dust. The correct number for the board is AA98-00188A. I made a typo in the first post.
