I have a LG 50PG20 tv, I just replaced the power supply board and got tv to turn on, but now there is a very thin (about 1/16") going across tv screen. Any ideas on what this is and how to fix it?

Re: LG 50PG20 plasma thin line going across screen
Did you happen to take the ribbon cables off the buffer boards? Maybe try reseating the offending cable.Did I leave the soldering iron on? -
Re: LG 50PG20 plasma thin line going across screen
yes I removed all ribbon cables from power supply board. That could have an issue with one thin line across tv???Comment

Re: LG 50PG20 plasma thin line going across screen
No I meant the ribbons that go into the panel directly. They are copper colored. On the far left.Did I leave the soldering iron on?Comment

Re: LG 50PG20 plasma thin line going across screen
It could be a bad plasma panel. There is a small chance it is a Y-buffer fault but that is very rare.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

I'm new to this so I hope I'm doing it right So....I picked up a LG 50PG20-ua Plasma TV (Someone's throwaway pickup) First power up no picture or sound
Found power board to be bad and I repaired it. (Bad caps) Now all power volt readings are good. Still no picture or sound. I plugged in power cord, no click and the standby light on the on/off button comes on blue as soon as it is plugged in and does not turn off when button is push. I then pulled the main board off to look at it better and the initial inspection (front and back) I cannot see anything bad. Before I put the board back...10-24-2024, 11:12 AM -
LG 60PB66550 NOV 2014
PSU: EAY63168603
PCB: EAX65359531 2013.11.01 Rev:1.0
Main board: EAX65399305(1.0) 13.11.27 PU42A/PA42A/PD42A
Symptom:
While watching, just went black and started clicking relay every few seconds.
Initial diagnosis:
Removing JUST the main CPU/Input PCB from circuit stops the clicking. No problems with any other boards/drivers. (Removing all other boards and only putting Main back in is all it takes to start clicking again)
Deeper diagnosis:
Pulling pins #1/#2 (Blue/Grey) from the connector housing... -
Hi to all,
I was given this TV, an entry-level 4K 50" set. Some have criticized its lack of contrast and relatively poor colour rendering, but for my needs, it's very decent.
I reset everything to factory settings, but this line keeps on fading in and out when watching a streaming channel from the Tizen firmware. Interestingly, it only happens when TV is warm, after about 1h45 of it being turned on.
Watching a movie from an external source doesn't trigger the line as easily (needs 2 hours), and from a normal viewing distance, is hardly noticeable. It...01-10-2024, 01:26 AM -
Hey guys, I'm being offered an LG 50PG10 plasma with a vertical line running down the screen.
Apparently, if you give the TV a good smack on the frame above the line, it will go away for a while.
Does this sound like a bad solder joint or loose ribbon cable? Or a bad panel? If it's not likely to be a bad panel I will likely pick it up.
What do you guys think?
Thanks...11-24-2020, 11:50 AM -
Hi all, I tried searching the site for answers but I'm a bit over my head understanding some of what might apply and what doesn't, so please be patient with me. I used Freakaftr8's fix to remove the left driver board to restore picture to a black screen with sound Vizio E701i-A3. After doing so, I now have a large red vertical stripe down the center of the screen. The fix did require getting another t-con board from online, I ordered it before I knew about the mosfit fix for the old t-con board. I have tried cleaning the cable connections to the t-con board. I swapped the cables going from...08-19-2025, 06:11 PM
