I have an Aspire 5736Z. Screen goes black at random times, acts like bad connection. Any help?

This happens when laptop is connected to AC power or just battery -- so not a battery issue.  I can get the screen back by moving the lid, but sometimes it's not easy -- maybe getting worse -- upsetting!  Will this require disassembly?  I understand there could be a BIOS update, but I hesitate to try that with this symptom.  If the problem is a mechanical issue, software won't help.

Thanks!
