Not knowing the model number:
If standby light on front comes on the fuse is good, if not set needs to be opened and fuse looked at.
If fuse good someone needs open set and check all voltages on power board at the moment set is turned on.
This may determine if problem in power supply or another area of set.

I do agree with the tech but if the green led don't come on and the 7-blink error code is still there. check the connector from the logic board that will be the board under the small signal baord. The small signal board have the AV input on it. Check the connector from the logic board to the power supply there should be one connectore btween those 2 boards. On the power supply side second pin from the left it will say Vs_On if the set has 0 volts the proble is the SSB or the logic board. how to determain that is to Use 2 Jumpers to short J8003 & J8004 on the left edge of the PSU (see figure below).
Use 1 Jumper to short CN2012 on the lower left part of the Logic PCB (this will supply a 100% White signal to the Display).
Plug in the AC to the PSU thru CN8001.
If PDP panel operates with White field screen then problem may be the SSB.

Hi. Try, in back yours tv on left side of the power corde connector have on hole, inside of this hole have one main switch, using one insulated stick and sheck if this switch is off ( may be not ) but try. If you heva esperience take out the back cover and check the fuse on power board. Good lock

Power failures can cause all types of problems, have you firstly checked the fuse in the mains plug? If that is ok then it may have blown an internal fuse in the power supply board, these are there to protect the rest of the circuit from power surges.

Commonly it's going to be a power supply related problem. The two boards that need to be looked at is the Main Power Supply Board or the power supply board for the screen. The one that powers the screen, some manufactures call it a Backlight Inverter Board.
If you have some electronic experience, you can sometimes find a Service Manual for the TV over the internet for less than $20. It will have the all resource material for repairing your TV model. It's just the matter of replacing the bad part on the circuit board.
