    Same problem-the monitor light is "on" (green) but the screen is completely black. All connections checked...



1 Answer

Shine a flashlight into the monitor, if you can then see what is usually on your desktop, then your backlight has a problem.

Hp P6000 fans stop after 15 seconds. Hard drive light stays on. nothing on monitor

dead PC, DESKTOP PC ,as old as 2009.
the fans tells you the PSU shut off, for cause.
fans, so you saw all fans turn off or just 1. or 2 of 3.
my pc has 4 fans many have 3;
CPU fan stops ,cpu overheats , PC goes slow or dead. clean the lint off it.
GPU fan , video goes dead. if it overheats.
PSU fan is inside the PSU if it goes bad, PSU is bad.
no monitor stated, is it CRT or LCD is it 15 years old.
if the monitor is 2002 or newer the OSD screen works
even with PC turned off, press the select button see that OSD screen ? telling you the monitor is not dead in 1second flat;
i caN NOT understand why the HDD lamp glows,
if the PSU shuts off , most LEDs go dead, on my PC
the standby LED on the MOBO glows, unless you pull the PSU power cord.
your HP PC came with 9 different mobo, during its production run.
at least. so answers come harder from that reason.

here are some simple tests.
test 1
power on, hear fans run
does the DVD drive (or cd) button eject work,.?
do all fans not just 1 or 2 worK? look for all fans clean the lent out
or things will overheat,
PSU can be bench tested or in the PC case.
using a jumper wire, even the HP service manual covers that.

power on the PC (after keeping monitor on for 5 full minutes)
test 2
the Screen must say, "hit ESC key to enter HP setup" BIOS.
press the ESC key on the monitor
if no text shows up that is a dead PC< "text above missing{"
if the PC told you to hit another key do so.
The ESC key , activates the BIOS brain. this cause
all those pages to work as seen in your service manual;.
if BIOS is dead that is a bad PSU (monitor ok)
or CPU is overheated.
bad ram, take all sticks out and test 1 by 1, ask how. !
The PSU will shut down on up to 12 or more faults
but never shuts down the standby power bus. unless AC line pulled.
IF the PSU has fan as most do this is the first place I look.

rubina576, I see you haven't looked at the "date of manufacture" on rear of your VE155B!!!! Retrevo .com lists unit as time to retire. The long,"very thin", "cold-cathode-fluorescent-lamps" that provide a "constant" bright, "white light" on the reverse side of the LCD PANEL, have "worn out" and are very "tired"!!!! You can see typical lcd CCFL's at: and click on "products" you will see "lcd backlights" !!! YOU ARE NOT QUALIFIED TO CHANGE THEM. A technician will need to do it. Very time consuming procedure. If your ve155b menu button on monitor can't fix brightness for you, then your options are: 1. check with viewsonic to cost out a refurbed VE155b if you can. 2. Trade in unit for new wide-screen 2010 or 2011 lcd monitor. If this was of some help, please rate my response on fixya. By for now. 12fixlouie north of Windy City.

19"ViewSonic LCD Monitor wont work at all !!

If you have the pc on and the monitor light stays green, take a flashlight to the screen. If you can see the images while shining the flashlight into the screen, they will be hard to see but they will be viewable, then its most likely the back light. The vx900 takes 4 bulbs and they are about $12 US each. Anyone who knows how to solder should be able to replace them.
