I just got this tv from a friend and it did not come with the ID label, so the Model stated above is my best guess. It has HDTV capabilities. I measured the screen and it is 45" 9/10th as any 46" Samsung is. It appears that everything works except for the screen. The screen has no visible cracks. Power up sound and power down sound works when turned on and off. Source button and menu do not change anything on the screen. All indicator lights light up properly.
OK if it is LCD your and have sounds but no picture you possibly have faulty inverter board that need to be replace

Try replacing C51, a 10 microfarad 16v. surface mount electrolytic. It's near IC23 on the upper center of the board.
This part had high ESR on a couple of sets I serviced which
kept the power supply from starting.

I had the same problem and I replaced the t-con board. My t.v. is fixed!!!! I just couldn't see spending another 700.00 dollars for a repair shop to fix it. The t-con board is located at the top of the t.v. once you remove the back cover. Be very careful removing the two plugs at the top of the board which was easy once I figured out how the clips worked. there is a black lever like connection which flips up, then grip with your fingers the tab and slide the tape like wires straight out. The bottom plug is very simple. Also to expose the t-con board you will have to remove a heat shield cover. Once removed there is foil looking tape that needs to be peeled back to expose the board. The board is very sensitive to static electricity so if you have a grounding strap that you can strap to your wrist and ground to the frame while performing your repair. Its best to lay the t.v. face down on the kitchen table with a blanket to protect the screen. Good luck!

check power supply capacitors..i repair these every day and the power supply is prone to faulty capacitors..the capacitors should have flat tops and if they are bulging or leaking brown fluid, replace

When the power was restored you suffered a power surge. Anything plugged in that did not have a surge protector was at risk. plasma tv's are especially susceptible to this. You will have to take this in to a tv repair shop for an estimate.
If the estimate is over 200 you may want to consider a replacement. Also purchase a surge protector so this doesn't happen again. Regards, Joe
