DETAIL:
Some TFT LCD's FRU P/N46H5355 may fail with a symptom of:
- LCD screen is completely white or grey. An external CRT will work correctly.

The failure is caused by an intermittent connection within the LCD assembly and occurrences may increase by opening and closing the LCD.

All P/N46H5355 FRUs with this condition have been purged from FRU stock. Use current LCD FRU P/N46H5355 to replace defective LCDs.
