Re: Panasonic Plasma TX-P42G20B -3 red blinks

p15v scale 20k pin 4 conn. 1,97 wire 3.95
vsus pin 1 unable to test on all scales shows 1
vda pin 1 unable to test on all scales shows 1
over the scaleLeave a comment:

Re: Panasonic Plasma TX-P42G20B -3 red blinks
do not laugh please, but basic questions:
I should measure the resistance between chassis ground and the pins on VDA,VSUS when TV is unpluged from power?
it doesn't show any resistans on pins from the table
only few ohms but on pin3 /p11 and pin4/p35
how to check TP9011 if that test point is on the foil side ?
I should connect TV to power before?Leave a comment:

Re: Panasonic Plasma TX-P42G20B vertical bar
I noticed something, when disconnecting flex and connecting again there is no line on tv
but appear again after 30 minuts. The metal frame on flex starts heats up, I'v checked others one and is no heating like that.
Tom66 are you sure that c-board is a defective ? not flex ?
