SOURCE: bad connection between laptop and lcd projector

i am using an LCD projector Epson and keeps on breaking down. supplier will insist that PC is causing the damage. Is there a posbility that incomplete connections in the cabling will cause breakdown, missing grounding maybe in Hor-vert sync? Or can it really be the PC? The PC normally sends video/sync signals only. I dont know if it sends a destructive signal to the LCD cpu to get damaged.

The display connector contact on the motherboard is loose. If you can open the casing, you'll see a ribbon cable from the LCD part connecting to the motherboard. The connector is usually rectangular and connects downwards. Try pressing it in firmly.
