This was a challenging dog of a repair, but after too many hours I had to give it up. Items checked, replaced or repaired. LCD cable - replaced LCD connector - replace and repaired Invertor - checked backlight - checked LCD - checked Lid Switch - checked The LCD was first checked with a known complete lid from another DV1000, the unit still showed same result. So backing up
- checked the LCD connector first.
- noticed connector had internal damage -replaced (same problem)
- noticed motherboard pin 29 was also blown off motherboard - repaired (same problem)
- lid switch check for open/close continuity - passed
- backlight - passed
