Acer Laptop - Blank Screen

[Steve2009]

Hi there,

 

I have been handed an Acer Aspire 5520 laptop from a friend who has purchased a new one, but there is an issue with the laptop...hence them getting a new one.

 

when the laptop turns on, the fan comes on, cd drive makes the usual noise however the screen is completely blank. sometimes the laptop will stay on until i press the power button again, but sometimes it turns off within 4 seconds! every so often when it starts, the caps lock light is on but pressing the key doesn't change anything.

 

I have ran tests on the HDD and the RAM on different laptops and they have come back clear. the only thing i can think of is a problem with the onboard graphics on the MB.

 

I have googled this endlessly, found many ppl with the same issue but no proper resolution.

 

If anyone has experienced this or know of anything i could do, please get in touch.

 

Many Thanks

 

Steve

have you tried plugging the laptop into a external monitor ?

[Steve2009]

yer sorry forgot to mention that.

the monitor just reports having no signal, tried pressing the fn+f6 button to try and transfer output to external monitor but still no picture.

could be the the board if not working on external monitor, if it had worked on an external monitor then mabye the invertor

haha, i might just give that a go...with a fire extinguisher at the ready!

 

u always think, they should have put the tick in extended warranty, its only bout 18 months old i think!

Thats where Acer (and a few others) make their money, cheap laptops that are destined to go wrong and a warranty option... Sale of Goods act always annoys them the countless time I've had to call them and demand they resolve manufacturing fault problems.

 

Quite often the ribbons connecting screen to mainboard on those go (common on 5520 and 5620) and in doing so creates a short which stops the system from behaving as it should; i.e. not letting you use an external monitor either. Pop the lid and check the ribbon is intact.
