I have A Compaq monitor MV 320? installed to my desktop. When the PC is started, the monitor shows a yellow ?. It does not show any display.. The trouble started with the display showing more of yellow color and finally blanking off.
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
yellow on a CRT is formed
when the green gun is powerful
and the red is weak and blue dead (or off).
RGB, see your wiki on how to mix the primary colors to get yellow,
so my guess is the blue gun is dead, at the least. (and happens this old)
see, there are 3 guns there and 2 more to fail , from older black and white, or what we call monochrome.
in old old days, we'd (1960s)we'd put on a gun booster to get all 3 guns more powerful
then balance that. (TV days old)
in your CRT, monitor there is a OSD display
if you look there, there is a gun balance adjustment, play there, and get lucky.
OSD is menu button, on screen display
stay away from the rays, and do not touch the 15,000 volts inside, or get to see Saint Peter, too soon, if you get my drift.

check the pin # 1 of video input cable { broken or Bent }
if it is ok then there must be a problem with the cable or RGB Processing Circuit { Normally Dry Soldering of a faulty IC in the circuit of CRT BASE} .
SOURCE: My Compaq Presario Will not even show curser after start up
reboot and keep pressing F5 go to safe mode if u can see the screen , u need a video driver ,or try reformatting and re installing windows,
SOURCE: out of frequency range set low resolution or refer monitor manual
TO RESET IT START YOUR COMPUTER IN SAFE MODE AND GO TO DISPLY SEETTINGS SET YOUR MONITOR AT VERY LOW 32BIT 800 BY 600 PIXELS IT WILL SOLVE THE PROBLEM THAN RESTART THE COMPUTER
SOURCE: out of frequency range set lower resolution
reboot the system by pressing F8 if your using windows OS and select last good configuration.
you can try also selecting Enable VGA mode (press F8 while rebooting and select ENABLE VGA mode).
hope this helps, please rate.

Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.
