the inverter board has an issue, take the monitor apart and see if there a Capacitor that is bulged or leaking a brown goo from it, if there is a blown capacitor then replace them with same type and heat rating. after than put the monitor back together.

hope this solves the problem.

PS the inverter board is the Board with the big transformer on it its normally the yellow/brown colored board.

For this >2 years monitor, first place to look will be the power supply section, look for caps with bulging top, post back what you see inside so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

The problem can be caused by bad caps in the power supply, bad inverter circuits, bad lamps. You need to open it up and look inside first and report back what you see so we can guide you further, see example of failed monitors due to bad caps here: http://s807.photobucket.com/home/budm/allalbums

It can be one of thses: bad caps (bulging top or bottom seal) in the power supply, bad backlight inverter circuits, bad lamps. You need to open it up and lool for bad caps first, then measure the voltages across the filter caps, you should have 5vdc and 12~18vdc (there are two power supplies: 5vdc for logic, 12~18vdc for backlights citcuits) Post back what you find so we can guide you further, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

Check the power supply first for bad caps, then check to see if you do have 12vdc feeding the the inverter circuits, worst case will be the lamps, see example of failed VIEWSONIC monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

the two small bright patches are actually bad pixels.there is nothing to worry about as upto 5-6 bad pixels are fine.these bad pixels do not spread generally so no reason to worry.in case the number of bad pixels on the screen increase to more than 5-6 then you can get your unit replaced by the manufacturer if in warranty.

Getting another power supply will be costly exercise mate may be easier to get quote from a local tech if it is just caps that have vented and then weigh up the price difference as LCDs are quite cheap now.

common problem. your power supply needs to be repaired. you probaly have blown capacitors since it is not completely dead.

Hello,

This could be caused by a few things. First, be sure the capacitors you used are low ESR. You can't use capacitors from Radio Shack, they can damage the electronics. Second, on the bottom of the power supply board you will find 4 transistors, they may be blown out. Check them with a multimeter or transistor checker. If the transistors are blown, we carry them is stock if you need them.

You are not alone. I have a Viewsonic monitor that does exactly the same thing. Wasn't sure if it was the monitor or a "bug".

possibles problems are : 1 ) blown fuse at the power supply 2 ) cold solder , inspect the PC board for burnt or cold solder , good luck , AJ

Try unplugging it wait a while and plug it again. Sometimes that cures the problem, but I can't promise you it will. i had an HDTV that did that. I unplugged it for a while, and it never did it again.

carl_p90, I don't know what you are capable of doing in the matter of "checking" the unit's "switch-mode-power-supply/CCFL voltage INVERTER circuits"!!! I have responded to another VX910 that you should read first. (kimespinoza Nov 04, 2009) The only option I did not mention to her was to do the visual inspection for the possible FAILED electrolytic filter capacitors on the SMPS/inverter combo board! Visit YOUTUBE for cilps of "LCD monitor disassembly" and "LCD monitor repair" videos. The longer ones are more helpful! Also check out www.ccl-la.com/badcaps.htm to see what is involved in doing your own repair work if you discover BAD CAPS in your unit. Then get back here if you need some assistance. Tell us more about your VX910 such as age, approx total "on" hrs of use, and results of doing the "FLASHLIGHT TEST" that every LCD owner should know how to perform when encountering a non-sleep-mode BLACK-SCREEN of DEATH!!! I will be checking for a comment from you after you do some research on your problem. Here is a clue!! Do you own any of the NEW style CURLIE-Q screw-in CFL light bulbs! Same technology lights up your LCD PANEL!!! Only you have thin, straight lamps hung on rear of your panel. Bye for now. 12fixlouie

Kim, The LCD display requires WHITE light so you can see all the colors on the screen. Most BLACK screen problems will be a power supply problem internal to the monitor. I monitor is still under warranty, have Viewsonic repair it. Here are a few more options that could be available if unit is out of warranty. 1. Trade in for new widescreen display. Please note that the electronics technician at the store will evaluate your monitor and try to repair it for less than $10 in parts! He or she will keep it as a spare unit or sell your monitor for $40 - $60 to a buddy that needs a spare or second monitor. 2. Check to see if Viewsonic has a CASH+old unit swap-out program. They ship you a REFURBISHED same model unit w/ 30day warranty. Yes! They will REFURBISH your old monitor and ship it to another customer. But that's only if a swap program is in effect! 3. Check with a local TV/LCD monitor repair shop, to see if they refurbish LCD monitors with new or rebuilt "switch-mode-power-supply" / "inverter supply" / "cold-cathode-fluoiescent-lamps" . 4. Most costly option. Buy new display AND have your VX910 repaired and kept as spare unit! Before you do any of the above mentioned options visit (FYI) YOUTUBE and search for and view the longer (8-12 minute) video clips of "LCD monitor repair" and "LCD monitor disassembly" to learn what the most common causes of LCD BLACK SCREEN failure are and what parts are used to fix them. Also visit www.ccl-la.com/badcaps.htm and www.lcdparts.com , www.badcaps.net for more information. If your VX910 falls into the FAILED CCFL backlight catagory get back here to fixya and let us know what option you will persue. If this was helpful to you or someone else, rate this response on fixya. 12fixlouie by for now.

After some research it seems you have an inverter problem. If you a EE wiz kid, replace some caps/transistor (MOSFET) chips/and a fuse and your back in buisness... Or www.lcdrepair.us will charge you a flat rate to get back on line. It's always an option to upgrade to that 24" touch screen you have been waiting for - black friday is just around the corner.

Take the side cover off the PC make sure the graphic card is seated firmly in its slot. This has no doubt moved when unplugging or putting it back together. Check other boards and connections while youre there. Hope this helps ............cheers from Scott
