2.I recommend you to connect your laptop to an external monitor and switch the display between the two using the functional keys and when there is display on the external monitor, reinstall the display drivers. If there is no display on external monitor, the problem might be with the display adapter.

there r a number of possible causes;

1st thing to do is to look at the screen under a bright light. If u see video then the backlight is out. that may be a bad inverter or a loose wire.

if u see nothing, next bet is a loose video cable to the screen. That requires a partial disassembly to get to it - I have had a couple of these on an HP.

If not that it may be a bad video bd/circuit or a bad screen. The only test here is to replace them.

bd is cheaper, if it has one -

it may be integrated, then it is not so much cheaper.

screen is pricey.

either of the latter require serious consideration to opt for new laptop.

The $500 quote is surely surprisingly plenty ultimate - you could attempt getting expenses from different places, yet they at the instant are not likely to be plenty greater powerful till you could detect an comparable gadget it is broken, yet has a stable exhibit. in maximum cases, if the exhibit in a pc dies, you will actually spend greater money fixing it than to in elementary terms replace it. The lcd area it is broken IS the 'exhibit', not the sparkling conceal/case. that is maximum of what you paid for once you acquire the pc. you're ultimate to be leery of people ripping you off, yet that's one case the place they're capturing rather immediately with you. Your in elementary terms different selection is to plug an exterior visual exhibit unit into it (lowering that is portability significantly). (Edit: the 1st answer must be ultimate - whether it relatively is comparable to the unique lcd exhibit, yet probability is the '$one hundred exhibit' can't be the final one - and you could't in simple terms get any low fee random exhibit and anticipate it to greater healthful/paintings).
