Panasonic Plasma TH-P42X10Z

Hi there im new to this site and hoping somebody can help me.

I have a Panasonic Plasma TH-P42X10Z tv when i go to turn it on the stanby light blinks 7 times and it wont turn on, I was hoping somebody can tell me witch board is faulty so i can go online and order a new or if there is a way i can repair the faulty board and get my tv up and running again. I have opened up the tv and looked at all the boards and all the capacitors seem fine and everything looks as it should be. Im stumped on what to do next. Any help would be great, Thanks.

sc,sd,su. have a look at the SC board and see if there is a small 2 pin white connector labelled SC50(it's a test jig) if so then this is what you do.

Disconnect the 3 white clips at the Sc board that connect the buffers. there's 2 on the SD and 1 on the Su.

then , there are 4 grounding bolts that bolt the sd/su to the sc, 2 each board

remove them

then at the Sc50 connector you need to short those 2 pins together.

then turn tv on as normal and see if 7 blinks or no blinks, I think you have a green LED for on when the TV is running.

If it 7 blinks it's the Sc and the buffers need to be checked for shorts.

If it stays on then sc is good and one or both buffers have failed

Hey thanks for the advice. I followed your instructions. And it still does the sam blinking lights 7 times, So what would be the next step that i would take ? And also could it be the power board ? I noticed theres 3 fuses on the power board, Can these be replaced ?

not power board

perform tests outlined on page 27 & 29

you will need a meter able to read more than 2 meg ohms
