For various political reasons Samsung is on my "Do not buy from" list.

However I have an LG 32" LCD with a similar story, burned up power supply with the following options:
1. Go out and buy a new driver chip and better caps and rework the board.
2. Hire someone to repair it for a little less than the price of a new one.
Or what I did.
3. Purchase complete new power supply board for ~$50 and hope for the best.

I took the TV apart, removed the power supply board (1 PCB and 3 connectors) and googled the part number. I ended up finding what I needed at Shopjimmy.com

Note: TV's been working fine for about half a year now.
