If you have a sound and no picture, especially if it flickers then it rules out the main board and CTRL board being bad. You will want to replace the Y-Main board, but when you replace the y-main board you should always replace the upper and lower ybuffer boards because they can short out your new Y-main board.

There are several possibilities here. Four different boards are involved in the horizontal scan of a plasma tv. The most likely order of failure for what you describe is; SC board, Su and SD, and finally the SS. These are Panasonic's names for what are more commonly known as the Y Main (or Y-Sus), the upper and lower Y buffer boards, and the Z main (or Z-Sus). Sorry I can't boil it down any further for you,... would have to measure voltages, etc.

All you need to do is to open the back cover of the television to check for burnt transistor , this is always the problem , for you to fix this it require a basic knowledge on electronics,
Your power supply board is not yet dead, u know basic electronics' and soldering? Most of the times, the power supply board just have dead leakages gases capacitors.These capacitors always bulges up on it top,or puff up on it top.Replaced these gases leakages capacitors will get your TV power stable,and work again.Or tries websites like Shopjimmy.com,Ebay.com to buy a whole refurbish power supply board for the replacement.
I hope this will help out in solving the problem
