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

Viewsonic VX2835wm monitor that powers up with a good screen for a couple of seconds and then goes blank. I replaced the power board and it still does the same thing. Could it be the on/off switch?

FIRST WE DO NORMAL AND LATER TRUE CAUSE.
gee that is normal on all monitors and by Energy Star laws too.
the monitor if the PC is dead or in speed mode, shuts of in 15 to 90 seconds, all do, every one. the monitor has self sleep, all do. everyone ever made did. even back to CRT days.


and the OSD button goes dead after. that. too. fooling the untrained.
here is the first tests, NO PC connected at all
power on see power light glow correct color
then see Viewsonic splash screen push the menu button now. quickly, if button dead hold it for 10 to 15 second to reverse the button lock now, see OSD works.

if you test the monitor on a good PC not in sleep mode the but working PC, your monitor is ok.

this monitor is very very old, 2004?
it has CCFL back lamps not LED<
and all fully used CCFL lamps are now no good, used 8yrs a day at 5years are no good. that is why we use LED back lamps now.
this is what they do: all do , used fully.
1: goEs dead forever, (vast did)
2: INTERMITTANT . (BINGO YOU ) OR INVERTER DEAD.
3: DIM BULBS (like me. lol)
4 TURN YELLOW FOR WHITE screens.
5: STROBEs. (FLASHes)

AND A VERY EXPENSIVE SURE, THAT. AND LABOR.

that means just what it tells you
the PC is dead, PC video dead or video cable unplugged , dog chewed it , pins bent or plugged in wrong on 1 or both ends.
or monitor not selected to the correct input port (OSD)

PC power lamp glowing not amber or blinkikng
PC fans spin , PSU fan and CPU both
if PC has GPU card in PCI-express slot it must be use those ports only for video.

NO PC told
PC dead.
PC not stuck in sleep mode , hold PC power button for 10 full seconds to end it, (cold boot that is)

Viewsonic VX2880ML 4K monitor, front vontrols won't work, help.

power on and power on led glows normal , not yellow or flash.
then this happens splash. attached, 2014 made.
then that tells you screen is NOT DEAD is it? now? here?
(PC is dead or missing)
  • NO connections on 1 or more inputs.
  • NO sync
  • no signal
  • OUT OF RANGE
and goes black screen NEXT,. if all that fails power supply is bad.
if all that works the menu button works for 15 seconds turned on with no PC, and also works on all PCs if connected to one that are all good and not sleeping. test the monitor on 2 PCs if confused.

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.

When i changed my old monitor with ViewSonic VE155B Black 15" LCD Monitor, the beautiful pictures previously stored on my computer appear too dark. i checked the settings of monitor, but the brightness n...

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: www.rexim.com 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.

The view sonic VA1701WB display is totally white on the screen during up the computer and i check the CPU is booting up but at the same time monitor screen is totally white please reply the reason.

It can be due to:
Dead T-CON board on the LCD panel assembly due to blown fuse or just dead board.

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.
