My LCD just started flickering. It's constantly doing it during dark scenes. It's not the lamp, it's the LCD. Any idea WTF happened?
Damn this is the second modfied LCD monitor that has not lasted. MbayQ's turned green and now Lifter's is messing up.
It's really strange. One thing I should mention is that I moved to a new house. It's setup in a room built in the garage. There's a TV in there that gets a lot of nasty interference so I think there might be grounding problems. I think I'll try it in a different room.
I highly doubt the panel is pernamently damaged, but it is possible and it worries me.

At first I got very light flickering from my LCD but I assumed it was a cable sitting to close to another but now it happens much more frequently no matter how I arrange the cables but only runing 800x600. 640x480 is totaly flicker free. kinda weird, Im going to try a diffrent vga cable 😕 Im leaning toward picking up one of the NEC's off ebay to replace my hacked up 14"lcd
Lifter, have you made your enclosure yet? (I've been off this forum for a while)
Try shielding the enclosure from inteference, this should fix the flicker and maybe help improve the image from what it used to be.
Flicker is usually a sign of low refresh rates. But thats for CRT. Lcds refresh differently. Maybe worth changing the refresh rate tho.
Check the wires too, maybe the move hurt a joint.

I've managed to get rid of the interference I saw on my regular TV. I did this by grounding the satellite diplexer. The flickering is still there.
My projector has 1 component input (via Viewsonic N6). When the Xbox is plugged in, everything works fine (moveis and games). No flickering, even in very dark scenes. When I plug in my Hughs HD satellite reciever (which is hooked up to an antenna as well), I get flickering during dark scenes.
I'm going to try different cables, and try unhooking the antenna, etc. Just a matter of trobleshooting via process of elimination. The good thing is that since the Xbox works, I know the panel is not damaged or anything. I think it's the cables because they don't fit on there very securly and they are very long (verses the Xbox's component cables which are short and fit nicely). Thanks all for the advice.

The problem could be earthing. If there's difference in the ground potentials of antenna and power. I have this prob with my TV-tuner card. If I touch antenna and PC the same time I get small electric shock. The solution is galvanic insulation. You can buy these little devices from an audio shop. Usually they are for line audio (RCA connectors) but I've seen one for antenna cables too.
You can measure the voltage difference between your panel and satellite receiver, if there's any voltage, that could be the source of flickering.
Hope this helps.

Hmmm. If there is no flicker while your X-box is in, then i think we have safely ruled out the possibility of an lcd problem. it sounds like inteference from the satilite signal. or reciever. try viewing it through a computer monitor and see if it remains. A tv wont do it, cos tvs are much more forgiving then monitors.
