Hello, unfortunately this is usually due to hardware problem, In this specific situation it is most likely the problem with lcd panel itself (electronic on panel). Sometimes it can work after the units becomes cold (not working for some time) and you power it on again.
Anyway if you are not familiar with electronics , please visit proper service center, due to the high voltage inside.
Hope this helps.
I am sorry to say that, that mode of resolution is not compatible with this monitor, you must select from one of these modes;1920 x 1080 @ 60 Hz1680 x 1050 @ 60 Hz1600 x 1200 @ 60 Hz1440 x 900 @ 60, 75 Hz1360 x 768 @ 60 Hz1280 x 1024 @ 60, 75 Hz1280 x 960 @ 60, 75 Hz1024 x 768 @ 60, 70, 72, 75 Hz800 x 600 @ 56, 60, 72, 75 Hz640 x 480 @ 60, 75 Hz720 x 400 @ 70 Hz
It is either a faulty or loose connection or a bad cable.
If your pc video card is separate from your motherboard, you can open the case and pull it out - then push it back down to make sure its in there solid. If it is not a separate card, then the connection that you hook the monitor cable to is bad and needs to be replaced. Check the pins on the cable. Count them. Make sure they are all there and none have been broken off. Count the holes in the connection to verify how many pins there should be on the cable itself.
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.
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.
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.
PC not beeping
PC not texting errors post.
PC not blinking codes on LED or caps lock or POST ERRORS !
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)
test monitor on end good PC? yet?
WHY DOES THIS SEARCH SHOW.The Viewsonic VSR220 no such thing.?Turn the monitor around, 180 and see the TAG sticker with real model toldno PC told , what PC is this?this ? VSD (D key is next to R) so huge typo"?https://www.viewsonic.com/eu/products/lcd/VSD220yes that is a PC (android)but can do monitor like duty. too.it needs service.if screen is dead, it has power problemsas the screen must at least show a viewsonic splash as power is turned on.try it on a 2nd room AC power jack yet:?if in warranty take it back to the storeor call viewsonic for help.the android PC can use an HDMI cable to a PC and works as a monitor.too.the manual states"4.5 Connecting to HDMI-compliant Devices via MicroHDMI InputHDMI (High-Definition Multimedia Interface) is a compact audio/videointerface for transferring uncompressed digital audio/video data.

Hello Edelberto, this monitor does not disarm by the back to disarm the monitor, you have to remove, with great care, the front frame and there you will see the obstacles you have to remove the panel assembly and the platelets
I hope you can disarm it, comment the results
Greetings Franco Dosil
Hola Edelberto,este monitor no de desarma por la parte posterior para desarmar el monitor, tienes que retirar, con mucho cuidado, el marco frontal y ahi veras las trabas que tiene para sacar el conjunto del panel y las plaquetas
Espero que puedas desarmarlo, comenta los resultados
Saludos Franco Dosil
