Re: LG 60PV400 Circuit check automatic shutdown

I will check all the cables again, and look into a main board.

Thanks again for all the help!!!

Re: LG 60PV400 Circuit check automatic shutdown

With no power to the main board the patterns display perfect!! I am going to go out on a limb, and guess I need a new main board

Re: LG 60PV400 Circuit check automatic shutdown

Lets try these pics again...

Re: LG 60PV400 Circuit check automatic shutdown

Hopefully the pics show up. I disconnected the cable, but didn't disconnect the main board from the power supply, and the power relay clicked off before the screen could turn on. I have that power cable disconnected now, and I am going to give it 10 min then try again...

Google is my friend. I found what points to short to get the test pattern to display. I am going to try to test this out tonight!!

Re: LG 60PV400 Circuit check automatic shutdown

Thanks for the advice. I should be able to take some pics tomorrow evening, and try to get that test pattern to display. Do you know off hand what pins I have to jumper to get the test pattern? I was not able to get a service manual downloaded.

I have an LG 60PV400 that has a problem. Just started last week. I turned the TV off, then heard it clicking every few minutes, also the standby light would turn off, then on again. I hit the power button when the standby light was on, and it booted up just fine, picture was perfect so I shut it down. I unplugged it for a few hours then tried again, and when I plugged it in I can hear a click from the main power relay, the standby light comes on, then after about 5 seconds I hear another click, and no standby light.

Here is what I have done so far.
Disconnect all connectors...

Hi My name is Ryan, and I am from Nanaimo, BC. I am an electronics engineering technologist, and I work as a Biomed. So basically I repair all kinds of stuff for a living.

I have an LG plasma that just died on me, and I am hoping to get some good troubleshooting advice. I would hate to throw out a plasma with how rare they are becoming!!

Thanks,

Ryan
