Question about ViewSonic Computers & Internet

1 Answer

Viewsonic VX2235 22" Flat panel monitor has been gradually declining with powering up, blinking on for a couple of minutes and then goes black with green power light indicator. Turning power off for a while, then turning back on with like results. Every once in a while it will flicker on showing the screen saver, but as this problem has progressed, it's now preventing my computer to finish it's post at boot-up. Sounds like a probable power supply problem. Any other ideas?

Connect the monitor with another desktop. If if works then problem is with your ram/graphics card or motherboard with inbuilt graphics. If the monitor functions the same way as before have a look at the pins on the connector. Bend/dirty pins can play havoc. If they are ok take the monitor to service centre.

VA902b Viewsonic monitor just went black this morning while working. Tried updating driver. Reboot. Does display during startup and goes black again. Monitor problem or hardware? I have 2 monitors.


The best thing to do to isolate the problem is to connect the problem monitor into a known working CPU. If the same problem occur, then the problem is the monitor. You may need to check if the power light (LED) is blinking or no light at all.

If there's no light, you may start replacing the power cable if the cable is detachable. But if it's built-in to the monitor, then send it to the authorized repair shop. They need to check if the panel is shot.

Thank you and good luck!

ViewSonic 19" flat screen monitor goes black - intermittently


Hi,
There could be a problem with your display card settings or the display card itself. If you are using Windows operating system, make sure that you have the monitor driver installed for that specific monitor. This is to ensure that Windows only allows settings for which your particular monitor was designed.
Let me know if I can assist you any further regarding this.
Best wishes,

The monitor blinks


That is a faulty inverter.

The inverter is an high voltage board that supply power to the back light lamp. In your case it is faulty and it is cutting power every now and then.

The part should be tested and replaced.

The blinking green light on VX922


If there is a flashing led on front of the monitor, that indicates a fault condition.

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.

If under warranty contact Viewsonic to find out a Viewsonic service point.

If you want to repair at your own expenses, just locate any good qualified repairer.

Problem with 17" ViewSonic Monitor


The same problem w/ my viewsonic E70 17" monitor.The viewmeter or viewmatch color on screen do not appear when power ON, although the green led power is ON.

But if you rest your monitor for about 10 hrs or more the viewmeter will appear when you power ON the monitor.

You can now start your CPU.

Remember : No viewmeter screen on monitor when power ON, means no supply coming out the picture tube or high voltage.

But if there is Viewmeter on screen , this normal and OK>
