Hi David, I doubt it has anything to do with the LCD cable. It sounds like you are caught in a restart loop. Can you access the BIOS and view all the attributes? Can you boot into safe mode? Can you access the recovery menu? Have you considered a repair install? What OS is the laptop running? Did the customer do anything right before the problem started (downloaded a bunch of Win Updates, installed new software, etc). Any chance this could be a malware infection at play? Have you tried running a malware scan at boot via an AV rescue disk?
Liquid seeping from a LCD could be due to a temperature extreme or physical shock. I don't know if the substance in a LCD is conductive - that could easily cause weird problems. I think a display replacement should be considered.
Hi The Dev, A smart test move on your part! Who knows at this point? However, I'm guessing a clean install on the original hard drive might solve the issue as well. Also, please consider Mutagen's suggestion when looking at a total repair solution that's right for the customer. Good luck with your efforts from here. my2cents
