Viewsoniv VA 902 LCD 19" monitor

check for any blown capacitors at the power supply board.

I would like to understand if the screen atleast flicker when the system is turned on. Is the screen power led lit on or flickering. In case you have no signal on the screen or no blinking also, you may have to get the lap for a HW repair as it could be a lap monitor HS issue. Else it should show atleast the initial screen while boot up as the screen would be working with the basic Bios Instructions which doesnt have any driver or complicated OS Code to run the screen. So ideally it should work at the initial stage of Bios to confirm that the screen has no hardware issue. Good Luck.

You might need to change the input on the TV. I'm almost certain that it will have a DVI and Coaxial input among others.

Check the monitor for an input button or pull up the menu and see if there is different input selector.

Hi,
I think your signal Cable is not connected properly.please check. Is your computer booting. Can you see HDD acivity LED blinking in your CPU?
This should solve your problem.Best of Luck.Please rank me appropriately. If you want any clarification, Please get back to me

I recently had the same problem occur on my LCD Panel and this is the response I received from ACER.

Thank you for contacting Acer America. I apologize for the inconvenience that you have experienced. If the green power on LED blinks rapidly, it means that the monitor is not getting any signal from the computer. It is possible that the monitor may have faulty internal component, I suggest that you send your monitor to a local repair shop to have it tested properly.

Respectfully,
Acer America

Hi, This has happened to me a few times. I found few thing that it can be,

1. The motherboard has a fault so will need replacing
2. Cpu is burnt out or faulty so will need replacing
3.Problem with graphics card

start from bottom, what you can try first is reseting bios by locating the jumper swith keep mains plug out . If you need help with this let me know. Also can try battery take out but doest always work properly. Hope this has helped. Thanks

This is the same problem with my 4 VG800 Monitors, you should be able to find the correct capacitor on your monitors by following the same procedure, I'm sure the boards are similar. Just get the correct value capacitor and try it in parallel with the initial filter capacitors right after the DC power in.

Alright, I had 4 VG800 monitors with the exact same problem. The front led is blinky OR constant reddish/orangish OR picture is white with colored vertical lines OR no picture with whistling from the back of the monitor and backlights illuminated. All problems have the same solution. You need to disassemble the monitor (2 screws on the back, remove lower front button panel, remove 2 screws holding panel in and remove speakers, then remove panel and unplug speakers. Now remove lots of tape and screws from the cover in the center of the monitor). Now that you've exposed the amplifier board and the VGA to LVDS board, you want to look for the pair of 25V 100microfarad capacitors that are nearby the DC power in (they are right next to the black "100" inductor). Desolder the capacitor farthest from the DC jack and replace with an electrolytic with the same specifications. If you want to check that this is the correct solution please put the new capacitor (WATCH THE POLARITY) in parallel with the capacitor there want watch the front panel indicator go green and the monitor work properly.

I'll be posting and Instructable entry in the next few days on the process, watch for the username Waterppk on the website www.instructables.com
