Question about ViewSonic VG2021m LCD Monitor

1 Answer

This viewsonic has a unique problem: when powered up, it enters the screen brightness dialog and rapidly cycles between selecting bright/contrast submenus, circa 4 cycles per second. Unresponsive to any controls, and rebooting it has no effect. The rest of the screen will respond to software operation. Sounds like a logic board problem to me? Or a broken microswitch, even though it feels like it is working properly..

Sounds like your monitor is going bad. You might get some more use out of it if you power it off for a couple hours and try again but my guess is this is a heat-related failure that is common on ViewSonic monitors.

How do I adjust lamp brightnesss for a Viewsonic PJ550 LCD projector?


hi,
may be ur projector lamps reflector may be faulty. when it comes to the end of its life. the coting inside th reflector will get bubbled and it will peeled of. that's why the light is very low. u can't increase the brightness of lamp. because it is connected to a well regulated power supply. and the supply voltage is as per the specifications of the lamp. you can adjust the brightness through menu. for that press MENU button and selects PICTURE 1 using down arrow and then press ENTER. select BRIGHTNESS and press ENTER. using up and down arrow adjust the brightness. if still not get the desired brightness lamp should replaced.
ok

ViewSonic E70fB Brightness & Contrast problem


Sounds like the buttons or the button panel are messed up. Or it has gotten moisture in it.

The only time i have seen this was when one of the buttons were malfunctioning, and we ended up replacing the monitor.
