Hi,
This kind of problem related to bad firmware saved in ROM that is part of main board so main board will be rpelaced to solve this issue.
It has nothing to do with power supply board that was replaced.
I'm not sure if main board is available some where as I could not locate it.
Thanks.

    LCD inverter board?

    Problem is in Main Board that has inputs jacks.
    Inverter board is some thing else, it provide high voltage to back light lamp to glow.

Hi aaron1970660,
Unplug the unit to the outlet then push the power on button for 1 minute to drain the voltages and refresh the board. Try to power it on again.
If the symptom still persist, your power supply was gone to out-of-regulation and/or missing some output voltages. Most common symptom of out-of-regulation was a bad filter electrolytic capacitor. Some gone leaky and some are dried which will result to dropped of voltages and disable the unit. Leaky capacitor has bulged/dome at the top and easy to recognized but dried capacitor has no physical indication. You must have a capacitor checker to determine its condition.
Missing voltages in the output stage was caused by open fuse/fusible resistor in line with a shorted transistor. You must know how to test this parts to pinpoint where the fault came from. Effective way to locate where the fault came from is by checking the output voltages...
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to look for an experienced technician to isolate the trouble. Also check if your unit is under warranty, if so avail it because the manufacturer will fix it for free or a little charged only.
Hope I helped you.
Have a nice day!
Thanks for using Fixya.

When i turn on the monitor its shows analog and then the screen goes blank but the power is still on what do i do? take note i think i need it to go back to the digital state its a viewSonic VG710s


First I would make sure the video out on your PC is working correctly. The best way to do this is by hooking your PC up to a different monitor to see if the second monitor operates correctly. If it does not then possibly you may have an issue with your video card. If you are interfacing to a laptop, make certain that you have the video out configured to output to an external monitor. This can be achieved through your computers control panel.
I also had a similar issue with one of my ViewSonic monitors and resolved it by completely unplugging the monitor from my PC and also for the electrical outlet. I let it sit for 5 or 10 minutes, hooked everything back up, restarted the computer and it corrected itself.
Hope this helps

I cant change my VT2230-M to the tv setting. I turn it on, the power light turns blue, and then the parrots come up. then the Monitor goes blank.


I had the same problem. It appears to be due to a bad tv tuner. Turn on your computer and leave the coax unplugged. Leave it for a while (15-30 min). When you see "snow" on your screen, you will be able to use the source button to change to another input and see if you can get a signal. I am running my cable through a dvd recorder and using the AV input to watch tv. Also, my HDMI, component and RGB work fine. After thank don't try to access the TV source until you have had your tuner replaced.

Have just hooked up my Viewsonic VA720 moniter as the main moniter to a new laptop that I have. The laptop is an ACER Travelmate 6293 running windows XP. When I come to start up my computer each morning...


You most likely have a capacitor that has changed value. When a capacitor goes bad it will work after it heats up. Sometimes a bad cap will have a bulging top or show signs of leakage. Sometimes can only be checked with a meter.

hi if your sure that all the power settings of the screen and the comp are fine then it points to 1 reason: the screen is heating up and the automatic circuit shuts it down... try locating it some cooler place or put a vent behind it... see if it does any help if soo set it in a cool place good luck
