It seems you need to replace the screen or the cable that connects it to the motherboard. If you feel you can get the necessary stuf and do it yourself, go ahead. If not, ask for fixed price for a screen replacement and compare with another repair shop in a nearby town.
PS. Don't they sell MacBook chargers via Internet in your country? In the USA, the original one is $79 via the Apple shop: http://www.apple.com/shop/accessories/all-accessories/power-cables, so I doubt if anybody in the USA would spend $120 for it.
I have a Sony Vaio T-series laptop (model SVT13126CXS) running windows 7. As of yesterday the screen is black...it doesn't display anything.
Laptop powers on (lights are on, fan makes noise, etc.).
I was able to plug an HDMI cable from my laptop to my TV and I am able to use the laptop using my TV screen (laptop screen is still black, but displays on TV works).
And the odd twist... this is a touch screen laptop, so I am able to touch my laptop screen and it makes clicks and moves cursor on my TV. (for some reason, the track pad doesn't work while its on TV display though).
Any help would be greatly appreciated. If you can give me steps into diagnosing the problem, that'd be great!
I live in a small college town and there is only one computer repair shop and since it's a monopoly he rips people off. Charges $95 for a diagnostic (if you get it fixed, it goes towards the repair; if not, it's $95). Charged my friend $120 for macbook charger and it wasn't even an genuine Apple product!
