HP/Compaq :: DV4t-1000 Screen Flashing

my daughters DV4t began having video issues. The unit had been flawless for a year but after the unit had run for 5 to 10 minutes, every 4 or 5 seconds or so it would begin flashing a pencil thin green line horizontally across the entire bottom of the screen. The longer the unit ran the larger the line would become until it consumed the entire task bar. It demonstrated this behavior in normal mode, safe mode, and in BIOS mode. I tried everything I knew (drivers, BIOS, etc…) to solve the problem without resolution.

Luckily we have an extended 3 year warranty with ADP. The unit is/was just over its initial 1 year warranty period (Christmas). The unit was returned for repair and HP replaced the lid, LCD, and associated parts. I’m happy to say that in 8 days the unit came back with no issues and in flawless condition, but I must also say that it’s a bit disappointing that such a failure should occur so early in it’s well cared for life.
