Acer V5-531 display issue

[tlaybourn]

I have here an Acer V5-531 laptop.

The original problem was a flickering display.
After disassembly it seemed that the flickering changed (but not disappeared) when the LCD cable was moved so I decided to replace the cable.
Now the flickering has gone but the display is still not right, looking as if the settings are incorrect.
(see picture)

The old cable is p/n 50.4VM06.011. I found a cable on eBay 50.4VM06.002 which according to
http://www.pchub.com/uph/laptop/235-124527-31728/Acer-Aspire-V5-531G-Series-LCD-Cable-15-.html
is a compatible cable.

My question is, was I right to use this cable, or is it more likely that there is a fault (possibly new fault) in the panel?

How does it look on an external monitor?

Everything looks OK on external monitor.
The laptop display looks very similar to when you have the wrong driver installed.

I had one a while ago that had a similar problem and it was caused by interference from a power supply I had fitted! Changed the psu, end of problem.

Turned out to be a panel fault. Must have made the original problem worse when I handled the panel.
