I have a Samsung pn50a460 s4dxza (september 2008) . It's a plasma . Are those lines a bad screen or could it be a bad board ? Thank you in advance

Re: Black/Red line in the middle of the screen
Vertical line in plasma is an almost definite panel. -
Re: Black/Red line in the middle of the screen
Most likely blown COF IC on the bottom ribbons attached to the panel. Not repairable
Small chance bottom address buffer board fault but unlikely. I had this on one of my Samsungs, replaced the F Buffer with no change. COF IC blown and integrated with the panel.Comment

Re: Black/Red line in the middle of the screen
The bottom buffer boards just distribute the same signal to all the buffers... if it were a bottom buffer, one whole part of the display would not work. Any small regional failure is almost always a failure of the panel.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Hello,
YouTube video of the problem encountered: https://youtube.com/shorts/q7TLNv36LUo
I am a pro and I have a problem that I have never seen despite my 7.5 years of experience on my own and my thousands of repairs, on a customer's Dell G3 15 3500.
On this PC I have already changed the complete palmrest because the keyboard was no longer working properly.
I also changed the screen because the PC fell and the screen was broken.
I changed the battery with a new and original battery.
I also had corrosion/oxidation on the... -
Hello everyone !
My name is Chris, I am a 30 years old embedded software developer working in the automotive industry. I am really passionate about learning new skills and repairing/crafting stuff. I came around this forum last week with the goal of repairing my faulty gaming laptop, indeed, I was video editing on it when suddenly a black screen popped and never disappeared
I bought some stuff to try to repair it and learn as many things as possible about computer repairs but nothing worked so far. When the black screen appeared, my legion 5 pro was connected to my external monitor...

Hi everyone,
I have this strange behaviour with Acer Aspire E5-574-52RH, i5 6200U, intel graphics, DA0ZRWMB6G0 Rev G, model ZRW.
Laptop came in for a SSD upgrade, took everything apart to install the SSD.
Everything started after modifying BIOS settings to boot UEFI instead of Legacy.
Laptop works fine, i installed windows 10 and drivers/updates, everything works ok(when it works)
The black screen problem is random, maybe 5 out 10 times, laptop remains with the black screen, no image
Symptoms are:

Hi guys, I have aquired a LG 55EG920V for very small amout of money.
I have jumped the Power on, DRV_ON and 3,5v pins just for the screen to show a black screen with a green line offset to the left.
Connecting everything together, shuts the tv off automaticlly after a couple of second( LG protection?)
Tried with a spare MB and the original, both the same results.
But if i unplug the 12v rail to the tcon or the larger LVDS to tcon, the tv turns back to the one line and dosent shut off.
Could this be a tcon issue or something...06-17-2023, 06:18 AM -
Hello, I'm working on a new deskmod pc project and have a problem with my monitor, an AOC U34G3XM, well, I may have bricked it.
The monitor was dismanteled and the separate parts parts integrated in the desk. the screen panel alone is on the upper part, and main board/video board + power board on the back of the desk (not enough place on the cover to fit it)
At first everything was working smoothly, then I decided to change the connexion between the video board and the screen for a longer one. Still working fine
During another reassembly, I made a mistake, and...
