yep i didnt open up the laptop just took off edge cover then unscrewed 6 screws and layed the screen on keyboard,unplugged the cam/mic,then unplugged the cable connection from the screen.Then put in new screen in the same way

Before i changed the screen everything was working 100% as the old screen was just scratched.

The only troublesome part was the screen display cable connection that fits into the screen, i had to try a few times to make it seat into place correctly,thats the only thing i can think of where i might of gone wrong.

thanks for your help with this jarotech.

I took it out and pushed it back in several times but still the same!

If the led screen display cable pin end was damaged trying to reseat it then would it cause these symptoms ive described??
 
Yes, because you have some pins with power and the pins before and after you have a ground. But, take out the cable and look at the screen connector for foreign particle, who could make a short. Also examine the cable and clean it from residue. Also disconnect the screen and try to boot.

It seems that there is alot of residue inside the cable connector which is hard to get at.

Whats best to clean it out with?

When i power up without the screen connected it shuts down after a few seconds so no difference.

 
So, you have the same number for both screens. You didn't open the base of the laptop, you removed the bezel and screws to replace the screen. Even if the new screen is not attached, the laptop power up for a few seconds and shuts down. But before it shuts down, when the screen was still connected, you saw the Acer logo on the screen.

Thats correct when i press the power button i get the blue lights etc ,faint acer logo then it shuts down after approx 5 seconds.

Just to let u know that when i first powered up the laptop with both battery and power cable after the screen change i heard a few bleeps aswell as the above but i dont get the bleeps now just faint logo then shut down.

Ive used some compressed air but still some remain in the screen cable but the connector on the screen seems fine.

Ive just had a closer look and it seems ive snapped off one of the gold contacts that are either side of the cable end casing.

Not the pins themselves but the bit thats on the gold casing on either side.

Would that cause a problem even though its not the actual pins?

Due to that it doesnt click into place like it should on one side

I could take a pic of the cable end to show you , but it seems that a new cable is in order :(

I have changed the power jack socket around 6 months ago which i had to take laptop apart with no problems but this has me stumped.
