Hi Elphk1,

Can you please try to identify the correct product number as PCG-71511M is a chassis model reference that can apply to more than one product? You should find this either on the screen surround or possibly a white sticker on the underside – It may start with VGN-

Try shining a torch on the screen to see whether you can see a feint image. If you can then this may possibly be a screen inverter, backlight or cabling issue. Also, if possible, attach an external monitor to see whether the problem is still apparent.

Hi Elphk1,

This doesn’t sound good. Did you press the Fn key + F7 to switch to an external display?

As there is no screen display you can’t even try a startup repair but to be sure try pressing and holding F8 at boot.

There are a couple of things you could try but I very much doubt that either will have any effect.

1 Shut down, remove the power adaptor and battery and then hold down the power button for 30 seconds. Then reattach battery and power adaptor and reboot.

2 Remove and then reseat the memory modules.

I suggest that you take the notebook to a local repairer (assuming that it is out of warranty) and ask for their opinion. This service should cost no more than £20 – Some repairers offer a no fix no charge deal with the exception of the collection or return charge.

Hey

I have a Sony vaio laptop, model number Pcg-71511m

I think the backlight has gone on it or a cable come lose, shine a torch on the screen and you can see the background.

Is this something that is easy to get hold of and change?

Thanks

Hi Havil52,

I assume you product model reference is VPCEF2E1E or similar?

If so I believe this has an LCD screen as opposed to LED and the problem may possibly be faulty/lose connection on the video cable or more likely a problem with the inverter as there is a feint image when a torch is shone on the screen.

If the inverter needs replacing the part is cheap (probably less than £10).

Hey rich

Yes that is the exact reference number, are they hard to take apart and see if it is a loose connection or change the invertor?

Do you know of anywhere that sells them as I have been looking online and can't find one.

Thanks for the help

Hi Matt,

I don't have disassembly instructions for your model and unless you feel comfortable with removing the LCD cover I recommend you consult a local repairer. Tolal cost of repair should be no more than £100.
