Question about ViewSonic VP191b 19" LCD Monitor

1 Answer

Monitor Blanking I have a ViewSonic VP171b that goes black at random times (anywhere from 10 minutes to 3 hours of being turned on). The power light for the monitor stays on (green), but the screen goes completely black. There is no warning (doesn't flicker, or get bright, or anything like that). I have to turn it off and leave it off for some time (usually between 1 and 5 minutes) and then it works fine again for a while (again random length of time). It does it not matter what program I am running. I have updated and re-installed the monitor and graphics card drivers. I have opened up the case and 'fanned' it and it didn't appear to help (not overheating of the graphincs card, cooling system in case working properly). Wiggling the connectoins doens't seem to make a differnce either. The monitor has worked fine for about a year before this happend. It was plugged into 220v 50hz (within the monitor's rating) for about 3 months before the problem started to occur. It is now plugged into a transformer (120V). Any ideas? My guess is the backlight, but I'm not certain. Is an LCD monitor easy to fix by yourself?

Viewsonic has trouble turning on-- seems to backlight (screen lights, makes an electronic hum), and then go to dead (yet the green power indicator stays on).

Hi, well if this is the inverter board, then its probably more cost effective to buy a new screen, same thing if this is the cathode lights. Reason for that is the technician will charge to replace, so cost will get anywhere from 50 and up. Only one question, how many years old is it? I do believe Viewsonic has 3 year warranties.

ViewSonic VP171b resolution problem

If you went from a standard screen to a wide-screen, you have to upgrade the video card.
Also, try going into the menu option on screen and have it automatically detect settings.
First thing you should do is update your drivers.
Should have said that first.

VX922 monitor, blank screen, blinking power light

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>
