Busted Laptop Screen

[Flashie]

I'm sure i've asked this before but what i'd like to know is what component is guilty of causing this, before i fork out a few thousand on a replacement part.

 

Is this the GPU causing this or is it a defective screen?

Booted up to an external display using HDMI. I guess i just solved my own problem then. Defective screen it was.

How will a replacement screen cost a "few thousand"?

 

Mind you in Rand (?) that amount is reasonable.

Don't rule out the cable itself that connects behind the LCD panel. Those things are very fragile.

You'll likely be able to get a new one off eBay for not much money (assuming it's not some crazy, high resolution display). I replaced my sister's busted laptop screen for less than £40.

In rand - that is correct. We dont use dollars here. Hot off the line from Dell Tech Support, it will cost R1272 for a new screen and R1347 for a new motherboard

It's not necessarily the display itself. It could also be the inverter or the cable connecting the display to the inverter. If a replacement screen is crazy expensive, I would suggest replacing the cable and inverter first in case it's one of those.

Never say never etc but...

 

•   Looks like the graphics department is outputting a signal (displays on an external display).
•   The inverter takes DC and makes it into AC to run the backlight, and as the screen is visible unlikely to be that.
•   The display looks like the individual pixels are working (althouigh it is the same image over and over again) so it is unlikely to be the screen itself.

So the problem would seem to be between the graphics system and the screen, the cabling?

That would be my initial guess, hence why I listed is as the first option.

I have also seen where the inverter board managed to mess up the display on older Dell laptops. I'm not an electrician so I can't begin to guess how, but I fixed a laptop that had display issues (the backlight was working, it was just putting out a ton of Red Green and Blue lines) and the fix was putting in a new Inverter board.
