Hello,This is a common indication that the power supply board has bad filter capacitors. When the capacitors go out the power board can not start up correctly so you get either a white screen, a flashing power light and no display, a flickering display or no power at all. The repair is easy, it just requires replacing the bad capacitors on the power supply board. About 10 minutes and a little soldering and your monitor should be as good as new. Here is a link to a repair kit with the correct parts to do the repair.http://www.ccl-la.com/catalog/product_info.php?products_id=145
your power supply probaly has bad capacitors on it. you need to remove the back cover and look for crowned and leaking capacitors. any electronics repair shop should be able to replace the m.
I would make sure that all the cables are securely connected to both the monitor and the pc computer (screwing the screws from the cable to the port will help hold the cable in). Beyond that, the issue is likely with the monitor and not something that can be fixed by the end user.
If the device is still in warranty (and checking the cables don't work). I would recommend sending it back to ViewSonic to have it fixed.
tarkan271, Will you please let me know asap when you get a genuine copy of the ViewSonic schematic for the "switch-mode-power-supply" and "inverter" circuit. Don't you know that they are "top secret" documents? You absolutely must do a NEW comment here on fixya if you find some documentation!! My suggestion to you would be to call ViewSonic and ask them if you can get a .pdf file sent to your e-mail address of the schematic and BOM. Good freaking luck, guy!! 12fixlouie
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. You canobtain the best user experience for video playback and gaming via HDMI.VSD220 is equiped with a micro HDMI input for connection to an externalHDMI-compliant device.

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

The problem is seems to be in power supply section. it may be need to repair by electronic technician, after using any monitor 5 to10 years there may be power section or lcd panel may be damage.
First, I'm not a Viewsonic representative.
* Check your warranty. call for support.
*** Following for information only.***
* No signal means no usable signal for a specific input on the TV or monitor.
* If it's just a monitor and not a multi-function TV that also has a Computer to video input then you need to check the device that's hooked up to the monitor as single function monitor's usually only have one input.
* If this is a TV then you need to go to the TV menu and check the "Input Source" to make sure it's on the input plug your using. (I'm using HDMi-2 on my laptop to TV)
* If it's not on the correct input then there will be a different signal (DVD, VCR, etc.) or none at all (No Signal) if those units are turned off.
* Unplug all devices (to reset) and count to 10. Power up and perform set up to your existing configuration.
* Note; as of Jan 2018 most cable TV are not broadcasting in analog (chan 3) and must use a digital tuner to get signal. Some cable Co. provide converters (for a fee?)
* Check with your service provider for more information.

PS, If you do have a damaged input (or feed) then check your video device for alternative outputs; IE: RCA Vid-Right-Left audio, HDMI, Split video (Y-G-B), VGA, S-plug, etc.
