Repeating the Same Post--Three Times--Isnt going to make replies ANY faster!!

Check for faulty IPM's...

When you are reading "1" on the Vs pins, what mode are you using, and what range?

OK this is what I have for the readings.
My DMM IS set on DCV. 200
The sticker on the TV shows; VA=60V...... VS =193V
there are 3 VS LOCATIONS. I plugged the tv in and it clicked twice on and twice off. I measured the 3 VS locations and they were all over the place.
130 down to 88.
The stndby locations all measured 4.9.

NOTE; If I leave the tv plugged in, it continuously cycles 2 clicks ON, 2 clicks OFF.
I unplugged the YSUS and I had 2 clicks and then NOTHING ELSE. I can press the power button and I get 2 clicks and NOTHING ELSE.
What NEXT?

Check on google how to run Lg plasma test patterns. You might need to remove the mobo to do this though as you will need to access the control board.

There must be an ohms mode on your meter. It doesn't have to beep, just write down the readings.

yea in diode mode. I am using a non audible DVM so 1 I believe is the same as OL.

Think it was in diode mode so basically OL. I think.

Re: Lg plasma tv will not power up. 60pc1d

Wait hang on have you tried running the test patterns ?

ROOKIE HERE. How do I check the test patterns? Thx so much for your help.

Re: Lg plasma tv will not power up. 60pc1d

check the sus output from the ipms.

ipms? Where is the sus output? Rookie here need guidance!

IPMS? im not sure what that is and where the sus output is located? Greenpea!

Check the Sus output from the Ipms.

Do i check this with the tv unplugged?

Let's make sure they are the correct boards for your set.

Re: Lg plasma tv will not power up. 60pc1d

I have a 60PC3D with a bad pdp..torn/cracked ribbon causing a line. I have all boards.

what are you thinking for the boards?

Re: Lg plasma tv will not power up. 60pc1d

You could also check those two ceramic fuses by the connectors to see if they're blown by putting a meter lead on each end and checking the resistance.

I checked the fuses in diode mode.
Both read = 0
Attached is a pic of the correct board that you suggested that I check.
I checked the VS lines and all readings = 1

Re: Lg plasma tv will not power up. 60pc1d

Look at the two large connectors in pic3 of post1 for one of the pins labelled VS. Remove power from set. Put dmm in resistance or ohms mode. Put one lead to that pin and another to chassis ground and report the reading.

UPDATE; With the power off,I selected diode mode and put the black lead on the chaSsis and the RED lead on VS (THERE ARE 3 VS OR RED CABLES)....
1. VS READING = 1
2. VS READING = 1
3. VS READING = 1
i attached a pic. Thx
