Question about ViewSonic VX910 19" LCD Monitor

2 Answers

LCD monitor problems.

I have two Viewsonic LCD's: models VE700 and VX910. The VE700, turns on, shows a gray screen for 3 seconds then black screen, the power stays on. The VX910, turns on, I see all the bootup process, when it gets to windows shows the desktop for 2 seconds then black screen, power stays on.

I have tried them both on 4 different computers, same problem. I have tried other monitors on the same computers, all work, so I know it's not a computer problem.

What can be wrong with the LCD's ? Inverter ? Backlight ?

Much appreciated. Thank you, Ed.

Re: LCD monitor problems.


If the monitors use seperate plug in power supply EG 12 to 24volts it could be that at fault.
Or it could be the invertor at fault.
I have had some success repairing invertors if you can use A meter remove invertor Panels & check accross the coils with meter set to ohms all the coils should read identical chances are you will find one set of windings either dead short or open circuit. This will be the faulty coil hopefully as your monitors are all the same make the coils will be the same.
Carefully desolder faulty coil & fit one that reads good from a doner board.
Look for any SMD type fuses & check or replace them & thats it I have done quite a few now using this method.
Give it a go.

I have a ViewSonic VX910 LCD monitor. I turn it on and it comes on for a second then goes black. I did replaced all five capacitors in the power supply board, but it didn't help, still the same problem....

AllI can think of is that a tripler or inverter could be breaking down, causing the unit to go into auto
shutdown mode. Some devise is breaking down, and causing the unit to shut down.
Not an easy problem to troubleshoot unless you've got a schematic and tech skills.
Hope this helps

I turn it on and it comes on for a second then the goes black

You need to open it up and inspect the capacitors (look for bulging top/seal), burnt inverter transformers, resistors, etc. in the power supply/Inverter board first, post back what you find so we can guide you further. See example of failed Viewsonic monitors:

Monitor turns black after 2 seconds, Viewsonic VX910

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:

My screen turned black and began flashing.

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 and , 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.
