Flickering crispy screen

old monitor , no PC stated, nor cable used < VGA>
test this old monitor on 2nd PC, if fails the monitor is bad.
it is 14 years old today, 2005 made
all this old are bad the toxic CCFL lamps go bad long ago.
best is the recycle center, it and buy only monitors and laptops
2010 or newer, or you get CCFL backlamps again.
the monitor this old has near zero street value, and repair costs are huge, nobody puts $1000 saddle on a $5 15 year old horse,
The CCFL panel can cost $100 and 1 to 2x that for labor
a used monitor is like $40 ,even walfart sells them called refurbs.

i would suggest a different refresh rate. should be in display properties.

bad monitor none told but 2010 and older have CCFL lamps that 99% are all dead now, EOL>
test old monitor on other good PC, to see if monitor is bad
and see if the monitors OSD button is dead if is the monitor is dead.
power on mon, under15seconds hit menu and OSD must pop up.
that is 1 of 20 causes I can do 19 more and 19 more tests but I full stop here.

CCFL lamps die at 20000 hours, even 5 years old possible.

Have the same problem. Old laptop works fine connected to Sharp Aquas LC 46D65U. New HP 17 envy connected by same hdmi cable has intermittent flickering (screen shuts between 1 and 2 seconds. Computer works fine on other tv's. .HP tech support says its not the laptop. TV's 5 years old. Tried 2 HDMI cables. (one suggestion was to change the tv output to 1080i or 1080p opposite to current selection, but I havent figured out how to do that yet). Wondering if its a window 8.1 issue....windows 7 works fine on the old laptop.

tad older post but not too old, and ignored.
it's an old monitor lucky you it works at all,
after all most are dead now, 99%
15 years old today.
if the OSD is dead under 10second from, power on
the Montors CCFL tubes are dead.
the fail these ways
1: dead for ever.
2: work intermitantly (you)
3:Strobes.(means flashing like in a DISCO)
4: only 1/2 screen dead, (2 tube displays)
5; turn yellow, for white
6: dim, for ver.

never seen any 15 year old CCFL screens good.
not me unless parked on self for 10 years.
the clue is on last page, in your manual, the word "
mercury Hg toxic, it's there, means CCLF tubes here)
the cure is 2010 or newer monitors with LED back lamps
do that now, end the pain of #1 soon to happen.

It looks like your UP button contact is demaged.
SOLUTION is to insert a piece from your business card mostly above the button to adjust it down or up. It works fine.

Hi,
I'm writing to you on a screen that is rolling and sometimes flickering right now. I've tried 3 different screens on the same outlet, and they all have the same problem.

1. If you have any speakers near your monitor, try moving them away, this might help because they might not be shielded enough.

2. Try another screen, if the problem persists, it may be your power outlet.

3. If you don't want to spend money on a new screen, spend some time looking for a 3-prong grounding adapter.

I used the 3-prong grounding adapter, those little adapters that plug into the wall using 2 prongs, and then you can plug a 3 prong appliance into them on the other site, and it helped make the rolls not appear as often, and not as dark.

I think it is something with my power or the plug I am using.

Hope this may have helped a tiny bit

I would bet it is the cable or connection. Have you tried connecting the monitor to a different PC?

adjust your screen at the back of tv flyback down you see the fucos and screen adjust the sreen ok

I have 2 of these monitors and have this problem. I was so frustrated turning the monitor off and on until the white line disappeared that one day, I punched the screen. And it worked! So now whenever this happens (about once every other day) I use my palm and smack the lower left corner of the monitor until the white line disappears. I like the color on these screens so I don't want to replace them until I have to. I will NOT buy another Lacie though.
