[QUOTE="chscag, post: 1407761, member: 46727"] No. The only possibility that I can think of which would prevent the screen from coming on I've already mentioned in my previous post. It's possible that either a connector was damaged or a video cable. Sometimes it almost impossible to spot that kind of damage. And may not have been your fault. As a machine ages inside due to heat build up, cables get brittle and connectors begin to separate. Remove the front display panel again but try to keep all wires and cables intact if possible. Make sure nothing hot gets grounded and turn the machine on. Then gently wiggle the cables and connectors from the display to the logic board. You may be able to find out that way. [/QUOTE]
