Question about ViewSonic VX910 19" LCD Monitor

Viewsonic VX910 powers on, screen displays for 1 second then turns off

My Viewsonic vx910 had a problem that it would power on, display the screen for 1 second, then go black. After reading some posts I found that I had two 25V capacitors that were bad. I replaced them and now the monitor cycles on and off, on for a second off for about 2-3 seconds. It displays the picture fine when on. Any ideas?

Blinking on and off is not always a capacitor issue, it is usually caused by faulty transistors at the high output transformers that light the backlights. Crappy board design ! But fixable in most cases.

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: http://s807.photobucket.com/home/budm/allalbums

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 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.

ViewSonic VX910 monitor appears to have power supply issue. The power light comes on for less than 1/2 sec, then goes off for about 1 sec, then just flashes green. If you play with the switch and the A/C...


try running the self test on the monitor
Self Test:
turn off the system disconnect the data cable from the tower and connect only the power cable to the monitor and trun on the monitor if you see colour full bars then the monitor is ok then try to go BIOS and see if the monitor is working

ViewSonic VX910 monitor has a power supply issue.


Your monitor have a bad condensator in the PSU.

The only thing to do is to replace the Power Supply Unit (very expensive, more than a new monitor) or if you have electronic tools, found and replace that condensator.(cheaper way...)

or

Have you connected your monitor with a new power cord ?

Best Regards!

LCD monitor problems.


Hi.

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.
