I'd second performing the backups just incase they're too lazy to to genuine warranty work, some places are quite lazy and just do a like for like swap and sell the trade-ins for scrap...

I am always happy to be corrected on this though, but certainly all the gfx faults I've had in the last 25 years have followed those general rules.

Quote from: nanotm I was under the impression a colum of grey or red pixels was either a dodgy connector or a vrm fault (change in colour based on screen type, led or lcd), multiple columns was bad vram and crazy paving screen effect was overheating gpu.
If the lines of iffyness are repeated in an equally spaced pattern, it usually the GPU at fault (frequently demonstrated by ATI/AMD brand graphics chips), but if it's one lone column of pixels or several columns in an irregular and colour-mismatched "barcode" effect, then generally it's the connections between the display's controller ribbons and the LCD itself that have either worked loose or are damaged from an impact, pics below show the differences...
In the latter case, it's new panel time (easy job, usually a few screws, undo a couple of plugs, play panel swapsies, reassemble and done), for those out of warranty panels can be had for not a lot of money (between £20 and £50) which can revive a perfectly working but damaged screened laptop for not a lot of money, done this many times myself both at the computer shop I worked at and for my own personal laptops...

If not, they're usually pretty easy and cheap to replace yourself or at a computer repair place if you're not confident.

I'm well acquainted with the amd problem after a certain manufacturers faux pas with using some dodgy electrolytic capacitors a few years back......edit; I should of probably mentioned that all credit to them they didn't even want the suspect kit back, just rang them up to say it was faulty gave the serial number and they fedex'd a new one by 9 am the following day, that they didn't check the replacement batch number was annoying but no more troublesome when it also needed replacing within a month ......some companies do spend a lot to get over their problems whilst others just pretend they don't exist (looks at the pile of knackered FTTC modems that keeps overheating.....wonders if BT will ever get any better)......

Quote from: southken I would have expected it to there all the time with a faulty connection.
They can be like that, it's basically a poor connection between the edge contacts and the LCD, sometimes makes full contact, some times doesn't (causing a solid line to appear), sometimes it's in the middle and flickers like a demented giant cursor...
But that said, as mentioned, Acer aren't exactly well-known for building decent laptops (I developed quite the disliking for them when at the computer shop), probably picked a budget-brand panel or something in a dodgy batch that wasn't up to specs so it was going cheap, but a new panel's definitely needed, whether or not the people doing the RMA agree is another matter...
