Solved Screen black but can be seen under good light angle

Specs: Windows 7
Hey all, I recently bought a Dell Inspiron One and it's been running great. A couple days ago though my screen suddenly went black (like it went to the screen savor) but it wont light back up. I tried restarting it but it remained black, but if I turn on the lamp next to the desktop and angle it correctly, I can barely see the sign in page. I've tried unplugging the computer from the wall and letting it rest for a couple hours but still nothing. Any ideas? Thanks.

✔ Best Answer
Failed backlight. I believe that unit is one of those all-in-one desktop systems ( like a laptop but with separate keyboard etc) I've never pulled one of those apart to see what's what but I suspect you will have to basically gut the thing in order to get at the screen components.

Unless you have the skills , replacement is a job for a tech.

Is it under warranty?

Yes its an all-in-one computer. I recently opened it up to make sure there weren't any loose wires and all the chips were in place good but yeah it seems i have to remove a layer of stuff to get to the moniter. It is under return warranty to the place where I bought it from but I already had to return a different one (same model computer though) for a hardware problem. Any idea on how much a back light would cost me? (I may be completely wrong but something like "replacing a bulb" doesnt hit me as needing to pay someone else to do it)

Well if you have opened the case you have probably voided any warranty you had.
For replacement parts you will need to go to Dell and enter the service tag number.

Two hardware failures for the same model PC? Just reinforces my personal bias against all-in one systems and Dell in particular. They build to a price. Quality is only a secondary consideration.

Also bad inverter can cause the blackout.
I think people buy all-in-one system because they look cool.

I think they buy them because they are cheap.

I cant say for others but I bought mine simply because i dont really have enough room where I live at the moment for a tower but thanks for all your help, two bad computers in a row is a good indication to get a refund and make room for a tower.

I would replace the inverter board first as they can be found cheap. but if it is the backlight then you will be looking at a replacement screen as changing the light is to much hasstle.
