common problems with these, usually customers here a loud pop. then the screen goes blank. I would try...
Some of these have a 4 pin test on the control board that you can jump with solder to get test pattern. If you get it to do that then these boards maybe good and would replace the control board. if nothing happens, then
the upper & lower drive also the Ysus and Zsus boards all at the same time.
last could be a defective panel.
hope this helps. p/n are on all the boards.

There are a couple of different things that could cause this problem, the first is the power supply, and the second the main board. Also either sustain or scan driver board can cause this problem. To know exactly what board is the cause, you need to have electronic repair experience, and test equipment. If you have this let me know and I will assist you in the troubleshooting of this tv. Otherwise you will need a repairman at this point. You can expect a bill of anywhere between $200-$500, this is a good average, however it could be more or less.
I am sorry I don't have a quick fix or easy answer for you on this one, please let me know if you have the skills and tools and I will be happy to assist you. Also please let me know if there is anything else I can do for you.
Let me know,if needed further assistance.
Hope i helped you.
Thanks for using ' Fixya ' and have a nice day!!
