This laptop boots fine on an external monitor but it's own display just lights the backlights and displays no image. I have bought a new screen and cable but it still has the same problem. The only thing that I have not changed is the inverter which does have quite alot of data wires going to it. I thought this only controlled the backlight though which does get brighter and darker at the right times when loading Windows and observing on an external monitor.
Could this be simply a bad connection on the motherboard or a dry joint? Just thought I'd ask for advice before stripping it completely.
Thanks in advance for any suggestions.

Phill.

Is it still under warranty? if so, ship it off and let them worry about it. It could be what you suggested or a bad spot on the motherboard, hard to tell though. In my exerience with acer laptops is that they have cooling problems and im always seeing motherboards burn out on them. Im not saying thats the case here, but Im not sure cuz Im not actually looking at the computer. :D

Thanx for the reply. It is not under warrenty, hence buying the new screen. I have just stripped it and cleaned the mobo which is not in any way burnt out. I have noticed though that the Nvidia graphics chipset is removable so I could try changing that although it is strange how it still works on an external monitor. The only other thing left is the inverter but the screen lights up just fine.
Hmmm...What a head jar!

If the external monitor works then it isn't the chip.

What is the make and model of this laptop?

Family and loved ones will always be a priority in my daily life.  You never know when one will leave you.

Double check all of the wires running to the screen for pinching/binding/breakage/loose connectors. Don't rule out the NVidia chipset just yet.

Get in contact with tech support and see if they have an extended warranty/service program for your particular model. Some NVidia chipsets have been having problems and are being covered under extended warranties with NVidia picking up the bill.

Can't hurt to at least try.

It's not the inverter. All it does is step up voltage to the backlight.

Thanks dpunisher, thought I could rule out the inverter. There is no warrenty and I have already replaced the screen and cable but the fault remains. All that is left is the motherboard and removeable Nvidia chipset. I'm going to guess and replace the Nvidia. Once I have done it I will post the results in case anyone else comes across this issue.
Thanks for everyones input.

Phill.
