* Is it flickering "in color" or is does it shift in brightness without changing color?
* Does the problem affect the whole screen, or is it visible in bands/streaks?
It's unlikely that a surge caused a problem, but let us know the answers.
It's an unnamed monitor, a generic one most probably. My video card is SiS 650. The monitor's an LCD type.
I tried it on another computer, and it's alright there. The flickering is 'in color' as you say. Usually, it's in straight lines that vary in width, and appear randomly around the screen. Though sometimes, the screen is turned into the color of the flicker for a second or two, before reverting back to normal flickering. The color is blue-green for some reason.
I hope you can help me, and it would be better to email me so that I'll receive it right away. Thanks in advance.

If it's an LCD screen, the most likely cause its that the flurorescent backlamp is nearing the normal end of its life (in the same way normal fluorescent lamps burn out - by flickering and blinking). A tecnician should be able to replace it.
If it's a CDT screen, the most likely cause is dust on the picture tube shorting the high voltage to ground. Get this fixed as soon as possible, or the high voltage transformer will burn up.

i havent tried this mon on a different computer or vice versa...
the flickering happens once in a while.. and it happens on edges of the screen.. u'd see some bright white fuzziness.. or it sorta resizes the screen a bit and then back to normal... hopefully this is fixable.. i really dont have the extra cash for a new mon now.. sighs..
Hi !
I'm also experiancing flickering issues with my laptop.
When i bend the screen at certain angles it works flawless, but then again on most angles it just flickers. On thing I've noticed is that when theres a dark background, black in particular it flickers even more. I don't think there is an issue with the video card, although i suspect that there might be a cable thats loose.
The computer itself is very new (HP Pavillion dv8000 only 5 months odl) so I don't think that its the backlight thats seen the best of its days yet... Thankful for any help I can get....

hi,
i have a 15" toshiba 5200 series Satellite laptop. the screen flickered and it went black. but there is an outline of the active screen image, but super super faint, but there. it is the inverter that runs the backlight? maybe it is a connection at the lcd or at the inverter (unseated connection)? and how will i know if it is the inverter. i would hate to spend 70 bucks to find out the lcd is toast.
last question: is a 15" lcd screen for a toshiba satellite pro 4600 a suitable/compatible replacement for the 5200 series lcd mentioned above? how can i find out? i have access to one but it will cost me 120 bucks
thank you everyone.
