 |
|
| I'm fixing a screen flickering problem on an HP Laptop. I fixed the probelm by screwing in the screws on the screen tighter. However I'm afraid it may come back. Any Help. |

Three things could be wrong and if tightnening the screws fixed it then it's probably fixed.
Otherwise the screen will be dead soon and almost impossible to fix.
I recommend you avoid closing the laptop to prolong it's life in the worst cases.
1.Loose LCD connection fixed by tightened screws.
2.Thin fragile backlight bulb and 2000 volt inverter circuit are dieing and need replacement,
risking getting a big shock and breaking the bulb if you can even find another broken
laptop to take them out of, and also risk damaging the LCD.
3.Very thin wires going to the screen are ready to snap off the mother board. I can't even
fix those. |

Screen flicker is seizure-inducing! And I just hate it....
I didn't know about tightening the screws. However, sometimes simply adjusting the contrast can visually help - a lot.
Another thing about some laptops: The CD-ROM drive. Since an inserted disc spins at X = unknown rpm this can shake the laptop, which in turn loosens the fittings and filaments. I've been told to be certain your laptop is on a secure flat surface whilst running a CD-ROM. One person I knew had a laptop that would actually vibrate when she ran a CD-ROM! By logic, this would contribute to the problems as outlined by ValMikeSmith.

If its only loose screws, try some lock tight on the problem screw, I was having the same issues with my Compaq lappy, v2570, solved that issue. Apparently the backlight bulb are replaceable, and I have seen some hardware hacks using a cathode case bulb, but that requires some tricky wiring to work. One trick with lcd's to extend their lifespan is to use a black backround on the desktop, lite backrounds tend to cause more of a flicker on the screen

The are made with shoddy materials, the lids are to flexible, so the frame screws tend to pop out near the hinges, my next laptop will be a 3 hinge model

And sauter that! Or at least duct tape.
I have a Gateway & an Apple ibook (for transporting). I've never had 'flicker' problems with mine.

| Sometimes dirt can aucumulate behind the screen for which you can use an online monitor cleaner like here:- Online Monitor Cleaner |
