20 Most Recent ViewSonic G810 21" CRT Monitor Questions & Answers

You need to download the most recent video driver for the video card in the computer. Open it up, look at the video card and then google the name of the card for the latest windows xp driver.

The problem might not be related to a single problem... It could be the tube or capacitors or Hv Connector or focus controller or the main board, etc etc...

If I am asked to troubleshoot this, i'll start from the Hv connector and then Capacitors and then FlybackILopt, etc... and finally Main board, this will take an extensive process and time and even if a you go for repair, technician will ask you to pay approximately $200 (including the spare parts) and that's not worth, instead you could buy a new Lcd Monitor with that $200 but if he/she is paid less I don't think the technician will do it for you. He'll spend a lot of time and power and many equipments to test all the parts.
I would suggest you to buy a new one than getting it repaired, but it's up to you, it's only my suggestion which I think is better for you.
For your reference, I included one picture with detail description of a CRT Monitor.


I can only wish you good luck.

Thanks for using FixYa.

PLease press reset botton on your monitor display and see any different. hope you find a good result.

It sounds like it is on it's way out. The lifespan for a CRT Monitor is about 8 years (at most) witha  noticeable decrease in quality at 4-5 years. I have seen them last longer, but not much. I would recommend getting a new 19" LCD which can be purchased right now for under $125 online. (Still 200 at Retail store) Opening it up to clean it out is not advised. (the dust could be the only thing keeping it alive) JK
Good Luck!

will,just try to check your power options properties...and go to the power saving and select the power schemes..then you adjust the setting for always on power scheme.you adjust after 3 mins or below...i think the power setting of your monitor is set after 20 mins ...

if that is a new and have a waranty why did back to the store and need for the replacement if the monitor has a warranty ...so just bring that and need for replacement...

it risky if you always use your monitor that has a factory defect..i suggest to return to the store for some replacement of your monitor...coz your monitor has a warranty.

a mylar capacitor 0.22mf 100v may be shorted besides the flyback transfomer.

The problem is that it is on the verge of going out my mother had a monitor go out and it did the same thing. Also if you have any high frequeny things around your monitor thatr also migh be the thing. Try a magnet or demagnitze the screen if you have one on it.

Question edited for clarity Videos for ViewSonic monitors, various models. There are notches along the edge and you use a Spudger Tool. https://www.google.com/search?q=ViewSonic+VA2431WM+open+case ..

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.
