3820TG - Green Line On Screen

Hi!

I've got a problem with my 4820tg - yesterday a vertical line appeared within the left third of my screen. At first it was dotted and purple-greenish and disappeared after and for a few minutes. Then it came back as a solid green line from the top to the bottom of my display.
This happened within Windows after a cold boot (first use of the device after some weeks) and a short time of idling but continued on while booting and within the bios.

What I've tried:
- change from the discrete graphics (Radeon 5650) to the integrated Intel one (no change)
- hooked up an external monitor (no line there, everything's fine)

Now i'm wondering if it is the display that is broken or some controller passing the signal to the screen.
Should i try to open up the laptop and take a look at the cables? Maybe the connector somehow got loose?

If i have to replace the screen i would try to get a used one since there is no more warranty - would it be possible to salvage one from a different model? If so - how do i know what fits?

Thanks

 

You can get access to the display cable by removing the keyboard and then splitting the base. If it's loose, you might get lucky. My guess is that you have a problem with the LED connections and need a new display. Replacement units are cheap enough that it probably isn't worth putting a used one in there.

 

Unfortunately i wasn't.

As far as I can see it costs about 60 euros to get a new display. I had hoped to cut that in half by getting a used one - time isn't that much of an issue. With luck I might even get a non-glare screen this way

 

I found a non-glare replacement for the T ZG: Display for the 4820 TZG

It looks ok in the picture. And according to this thread t-z-g-what-do-they-mean the difference between the models is the CPU. If this is the only difference the screen should fit but i'm not sure about this.

Does anyone have more insight or an idea how I could find out for certain?

 

It's indeed the only difference so it if is meant for TZG it will work in TG too.

 

Many thanks to the both of you

 

That is correct. The TZG has a dedicated GPU and a lower powered Pentium CPU. The display cable attachment on the motherboard is the same.
