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.

hello, amigo if the all the caps are godd then you have to replace the power supply board. don't try to fix it this is not an easy task. you are looking at almost $200.00 with tax an shipping. just go to google and type your tv model # and ask for the power supply board or just look for the part# on the board itself. good luck

Your 7 blinks (error code) means that your 8.6 vdc in the power supply section is faulty.This was sense by the standy-by power supply's initial test. This voltage is easy to locate in the power supply board, each output voltage is written in the board itself. Concentrate in its regulator circuitry. Look for open fusible resistor, shorted transistor and leaky/dried capacitor. The unit is disable unless you fix this 8.6vdc fault.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.
