Re: LG 60PX950 No video...
I fixed the cap, and the TV has been working fine until this week. Now it will lock up occasionally and restart on it's own, image freezes and it has to be turned off, or it will start artifacting like crazy.
If I turn it off and back on, sometimes it does what it was doing previously, not display anything on the screen. However if I leave it turned off long enough it will start working again (displaying an image).
Any thoughts at this point? Could it be another component is affecting this main board at this point and causing...

Yes, and the piece has two wires coming out of it... Like it wasn't soldered well or at all...Leave a comment:

Re: LG 60PX950 No video...
I got the board in today, I hooked it up and it's working but there was a loose piece in it and looking at my old board it's the piece circled...
A) What is it?
B) Can I fix it?
C) How is it working without it?...Leave a comment:

Re: LG 60PX950 No video...
Tom, do you know what the green reset button on the main pcb and the black reset button on the 3D board are supposed to do? Just discovered them tonight, they don't fix my issue, I'm simply curious. Hope to have my replacement board by the middle of next week.Leave a comment:

Re: LG 60PX950 No video...
Thanks again for all your help. Looks like I'm ordered the $180 board from tvpartsplus with 60 day return policy and praying the 3D board isn't gone too...Leave a comment:

Re: LG 60PX950 No video...
Looks like part could be listed under either: EBR71767001 or EBT61259501
Any idea on the difference?
Found the EBR version here for $180 listed as 'seller refurbished'. It's the same EBR number that's on my board sticker as well (apprehensive about the EBT version).

Re: LG 60PX950 No video...
Thanks tom, maybe all I needed was a nudge in the right direction. I guess I was worried about reliability since this board went out.
Can I call LG to get the main PCB or do I need to look around the internet to find it? SHopJimmy doesn't have it.Leave a comment:

Re: LG 60PX950 No video...
Well, I shorted those pins and it went into test mode, red, blue, green, black, white, then some bars. Guess this means I need to find a main pcb or just replace the whole TV? Any chance it's possible to bypass the 3D board to keep from having to replace that?
I'm just not sure on spending $200+ on a 3.5 year old TV when I could replace it with something probably better for $1100 (Vizio M Series 60")....Leave a comment:

Re: LG 60PX950 No video...
Just to add to this, I just left the TV on for a bit and felt the heat sinks on both YSUS and ZSYS and they were slightly warm... Not sure if that means anything but I'd seen people recommend determining if both were hot when troubleshooting issues. Some on the ZSUS were warmer than others, YSUS all seemed to be about the same warmness.Last edited by bradf79; 05-18-2014, 03:44 PM.Leave a comment:

I don't see anything out of the ordinary other than cobwebs... (wtf). No burnt marks are anything else. Let me know if you need closer pictures of any other pieces. The green light that flashes comes from the little green light board on the left (labelled CTRL) underneath the power supply (yellow board)...

Re: LG 60PX950 No video...
Still haven't gotten the back panel off, but I did video what it's doing in case that helps:

The blue light on the right lights up when I press buttons on the remote, you can see it takes a while before it starts 'accepting' them, can't remember if it was always that long or not, I'm thinking it was, but honestly can't remember.Re: LG 60PX950 No video...<br /> <b...g in case thatLast edited by bradf79; 05-18-2014, 07:43 AM.Leave a comment:

Ugh, I did some initial research on those two parts (control and main boards) and neither seem to be in stock anywhere except eBay... I'll post some pictures later.Leave a comment:

Re: LG 60PX950 No video...
I think it's digital COAX. I have an HDTV antenna in my attic that feeds it.
So the black powered screen is a no signal from the CPU? It doesn't have anything on it (like a no signal box), it just lights up black. What is it doing when it goes back to no powered screen? I tried pressing the input button multiple times with all other sources powered on and I could never get it to switch to another source, not sure if that means anything or not.
I'll have to take the back off the TV after the kids go to bed to post a picture. When...Leave a comment:

LG 60PX950 No video...
I got my 60PX950 in December of 2010 and while watching TV recently it locked up. The picture on the TV (from COAX input) was frozen and it was also overlayed with the "no signal detected" box. I turned it off and turned it back on and now I can't get any picture at all. I don't appear to have sound, but I don't know for sure because I had the internal sound disabled (using a receiver). It seems to respond to remote commands (blue light comes on), but again there is no picture, no sound through my receiver either.
I've read the post on common troubleshooting issues, but... -
