Problem with compaq MV 520 monitor

As you mentioned, your Compaq Presario MV520 is using Windows 98 OS. As we all know, dial-up connection is the only available internet connection at that time so obviously Win 98 has dial-up LAN connection. However, you wanted to have wireless connection on that PC so you need to install a wireless adapter to that PC. First of all, most wireless adapters that are being used for desktop PC are wireless USB adapter, so you need to have a USB port on that PC. And also, you will need to check if the software for the wireless adapter will be accepted by the PC because since the PC is using Win 98 OS, we are not sure if the firmware of the wireless adapter will be compatible to the PC. Basically, my answer would be not possible.

omg an antique monitor
a relic CRT monitor?????really?
is it really MV320????or a typo.
MV500s are CRT (heavy cathode RAY TUBES)
you model is rare now, no photos of it by you.so...
if not a CRT pig.
then it must be a flat screen monitor
the first ones, up to year 2010 used crapppy
CCFL back lamp tubes that are bad now. all are.
(unless never used)
call CCFL fail these ways.
dim.
white now yellow
dead.
blinks, or is intermittent,or strobes.l

the backlamps CCLF tubes are dead. all do that, or just die .
crt monitors
are junk and a fire hazard, trash it.

CRT fails more ways
sure dim,sure dead.
but it has 3 guns , RGB , red green blue.
the red gun loves to go weak first , red phosphors
are weak (a physics deal)
one trick (long long ago is to up the red gun levels, to compensate.
or lower Green/blue guns.
gun means "electron gun" deep inside the CRT neck

The CRT has even more bad effects, failed.
a huge endless list , if you want.we have it.
with photos

osd not display so that menu statust

My guess is that the ON/OFF switch is broken.

It's time to responsibly recycle your old CRT monitor, and buy a new LCD monitor.

you turned the brightness down

download.com has alot of free utility's for cleaning up a computer. Good Luck.

check the signal cable

the monitor is on its way out.
no fixes here. not worth the money.
you mention it is CRT. time to get a new one or go for LCD.

it could be th epower supply and it could be the monitor.
power ON button should not flash orange regardless what you do. it should stay green. then orange. not orange to green to orange.
try the monitor on another PC if you can fine one.
the other thing is are the 2 monitor similar (CRT to CRT and LCD to LCD), you can't mix the the two, they will work but need different video driver to function correctly.

Here is what you have been asking. q901 --- K2645 q902 --- KSP44 u90 --- uc 3842P It seems you problem is in the power supply switching circuit. I hope this will solve your problem. Please let me know if this has solved your problem junr7
