Monitor display problem

Its data cable is broken inside from the computer side or from the monitors back side.
it could be confirmed by shaking the cable one by one from both sides. Than try to change the cable

check your video input im id the right place. sometimes poor quality cables can do the same thing.

Hi,
If you are looking for a repair manual for your Compaq MV 5500 CRT Monitor, you will most likely not find one as CRT's are not designed to be serviced by the average user. Servicing a CRT is actually very dangerous work due to the high voltage and current the monitor can store.
However, if you were just looking for a user guide manual, I found one for you here: Click Here.
Hope this helps. If it does, please accept and rate the solution! Contact me with any more questions you may have. Thanks for using FixYa!

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

check your rams that may not properly installed.

if that is installed correctly then change BIOS battery....


no prob.

dry soldring in video board

First open cpu cabinet.
Then refix RAM memory.
Pull cmos cell for 10 minutes so all settings of motherbord are defaults.
Then pull porcessor fan and processor clean dust from all chip and parts.
Remove pci cards from pci slot then check.
Let me know if you need more assistanse.
Thanks.

The video driver may have reverted to a standard VGA driver or your
video driver has stop working and needs reinstalling.
