Re: 3 red blink in panasonic 65vt60
I took another reading when the ribbon of the SS board
Disconnected from the main board so the tv on with fan spining
The voltage on the Ss board stable
TPVE=149 VDC
TPVSUS= 200 VDC
This Is the highest I mesure is it low?
You mean the igbt need to mesure between legs
5000 ohms in the voltmeter screen the max I mesure
Was 590 ohms?
Thank you.Leave a comment:

Re: 3 red blink in panasonic 65vt60
ן do another test disconnected also the ribbon cable of theSS board and tv click no red light, now green light and 2 fan spining.
The voltage Also stable
TPVE=149 VDC
TPVSUS= 200 VDC
Maybe the ribbon cable is not good?
Or it is a problem of the SS Board?
When conect the ss ribbon cable the tv red light flash
8 times and voltage on the 2 test point of ss board falling quickly.
Thank you very much!Leave a comment:

Re: 3 red blink in panasonic 65vt60
I mesure transistors G C E
All of them is 570-590 ohms and 240-270 ohms
Between thr different legs but all is the same reading.
I find TPVE test point of SS board and TPVSUS of
SS board.
I isolated the SC board completely disconnected the ribbon cable and the Dc power connector.
Turn on TV and got 8 red light,
I mesure TPVE it start in 140 VDC and quickly drop to
0 VDC.
I mesure TPVSUS it start 140 VDC and quickly drop to
0 VDC.

Re: 3 red blink in panasonic 65vt60
You are right The SC is malfunctioning for sure
But I also get 8 red light blink when conect the ribbon cable of the ss to the main board.
My understanding in electronic is low and I love this plasma tv so I am trying to repair it myself by replacing the fulty board with a working.
About the ss board I attached picture of the ss board and I mark the igbt I think you meant that need to mesure them for short?
How I mesure them there is three leg?
Thank you very much!...Leave a comment:

Re: 3 red blink in panasonic 65vt60
I attach photo of*my ss board i dont know where*to find the*TPVE*or if there is one
I managed*to find diode that failed in the*continuity check*of my multimeter i measure it between the 2 legs and the multimeter*beef and i saw zero on the screen
I also check the power connector*of the ss board SS11 and no short*
Does it mean that I also need to replace the ss board because*of the diode?

I then also disconnected the ribbon cable...Leave a comment:
