Black screen, ext monitor works fine, invertor or screen?


Ive read similar problems on here but have not found answers soooo...

I have a Mac Book Pro 15"Core 2 Duo A1226

I bought it late 2007.

I put the laptop into sleep mode. The screen has never worked since.

It works fine if I hook up an ext monitor.

The computer boots up, chimes and even makes the zooming 'blip' sound of Skype starting up.

If I shine a light at an angle at screen I cannot see anything.

I have replaced the LDVS/ Data display cable with a new one but to no avail...

I have been told several options. Broken Invertor board or broken screen. Can anybody suggest based on the above info which it could be ? OR what tests I can carry out to define what the issue might be?

Any help gratefully appreciated!

The light at an angle will reveal a bad inverter if you can see the screen. You did the right thing by replacing the LDVS cable if you know it to be good from a reputable seller. Next thing is the screen. Check your work on the cable first. There were three different screen providers so make sure you order the exact replacement.

Thanks Mayer! Will have to pop it open again and look at the exact screen type and then find somewhere reputable to get one from. Will let you know how I get on!!
