I’ve been getting some comments on my HP f1703 flat panel display fix. Yesterday on Instructables, leevonk posted Repair a Flatscreen Monitor for $15. This is a good (non-specific manufacturer) tutorial on actually replacing the inverters and backlights.
Remember, even if the backlight isn’t working, you should still be able to see an image on the display in bright light (e.g., you should be able to see a boot screen or your cursor move) if the rest of the display is working correctly.
