Re: LG Plasma 60PN6500-UA Main Board
That's great, congratulations!
Off-topic:
I've been wondering how much money Best Buy is making off of their electronics recycling program.
When I first went to the PartStore.com site the sub-title stood out to me...
PartStore.com - A Best Buy Brand
I've used their (Best Buy's) free drop-off recycling service for a lot of computer hardware and several appliances.
I assumed they were selling all of the stuff to other recycling companies.
If they've...Leave a comment:

Re: LG Plasma 60PN6500-UA Main Board
Thanks to this great forum I now have a working 60" LG Plasma.
The Main Board (EBT62753601) from the source provided by Bob solved the issue.
Thanks to everyone who helped out!

Re: LG Plasma 60PN6500-UA Main Board
Thanks for the tip Malachi! It's good to hear from another user with the same model who has had a successful board replacement.
There are a lot of parts sites that list 5-10 LG models as all taking the same board. The problem seems to be the number of versions that LG went through within these models.
After getting burned once on wrong version number I'm giving another one a try based on a BC board member's success story. That board is supposed to arrive on Monday, 03/14.
If it works I'll post the results....Leave a comment:

Re: LG Plasma 60PN6500-UA Main Board
Well it was "free" and if PartStore.com can come through with the same board that saved Bob's ([url]https://www.badcaps.net/forum/showthread.php?t=47843[/url]) then I think it is worth $116. I've heard big plasmas are not so easy to come by.
Nothing ventured, nothing gained.
Thanks for all of the advice so far.
I'll report back whether or not I'm able to get it working and mounted.Re: LG Plasma 60PN6500-UA Main Board...e.com can comeLeave a comment:

Re: LG Plasma 60PN6500-UA Main Board
Thanks for the push to give it a try!
I scrounged a 10KΩ resistor off of an old graphics card I had laying around.
Soldered that in the best I could, made sure it wasn't bridged directly to R264 and between the ends of R264 and R270 I show 19.9KΩ where before it was open.
Also remounted the HDMI socket.
No luck on power-up though.
However, after trying all of that, I did end up finding a service manual online and Marty you guessed right about the resistor value......Leave a comment:

Re: LG Plasma 60PN6500-UA Main Board
Based on Marty's shared image above ([url]https://www.badcaps.net/forum/showpost.php?p=637596&postcount=2[/url]) and close inspection of the points it does appear that a resistor belongs at R270.
Also, I still have the original HDMI socket which looks like it is in good enough shape to remount.
Just guessing here but the deeper question I have is does the possible missing resistor or missing HDMI socket likely lead to a dead board?
Seems like a missing resistor in the 5V circuit could shut everything...Leave a comment:

Re: LG Plasma 60PN6500-UA Main Board
Tracked down the datasheet on the IC:

Re: LG Plasma 60PN6500-UA Main Board
Ohmed out the connections around the missing resistor on the USB power controller/switch.
IC204 reads: D82 | 020 | LU
I haven't been able to track down any specs on it.
The missing resistor, R270, appears to be in series with R264 between pins 4 & 5 of the USB chip.
R264 measures 10KΩ.
R271 measures 40Ω and has continuity with pin 4
R258 measures 40Ω and has continuity with pin 5
Pin 1 has continuity with ground and one side of C201....Leave a comment:

I got a line on a possible replacement board in this thread:

I'm still interested in learning more about possible repair of the damaged board pictured above.

Re: LG Plasma 60pn6500-UA red screen
Brilliant! Thanks so much for that info.
There seems to be a lot of misinformation about part number compatibility/valid substitutions at the various online parts retailers.
I'm willing to give this one a shot since it worked for you.
At the same time I'm investigating the possibility of repairing my board... details here:

Re: LG Plasma 60PN6500-UA Main Board
Ok, so what are the realistic chances of finding out the value of that resistor?

Re: LG Plasma 60PN6500-UA Main Board
Thanks for the closeup of a comparable board. Great image!
I wondered if R270 was supposed to be occupied but I had not found an image that was good enough to show it.
Other noticeable damage: HDMI contact #3 is missing it's surface and IC204 is shifted slightly in-board (but the soldering seems intact).
I didn't think there was much hope of piecing the old board back together.
Maybe folks around here will know better.

LG Plasma 60PN6500-UA Main Board
Hello,
I was given a non-working LG Plasma 60PN6500-UA with the hope that I could repair it and give it a new home.

Hi Bob,
Did you ever find a replacement board? I'm trying to track one down for the same model/version.

Re: New Members - please post your introductions here
Hi All,
I have kept one 9 year old RCA LCD going with information from this site on replacing 19 caps on the power supply.
I'm finally joining now to have access to the full site (especially image attachments).
Thanks for hosting this great community!
Peace,
