Model vg2021m. it fall and now it doesn't come

Model vg2021m. it fall and now it doesn't come back ON. I plug in the AC cord, blue light comes up, then it flicks and shuts down. I took it apart and found that if I disconnec the wires going from the power supply board to the display (4 white/pink/blue wires), then plug in the AC power, blue light comes up, then orange light comes ON. I can turn it ON and OFF. Of course, no display since I disconnect the wires. It is a good monitor and I would like to fix it. Any ideas?

Try another cord/charger with the EXACT same power specs as the original. Has the AC jack in the laptop been damaged, loose connection, due to pulling on the cord while plugged in? Try to wiggle it when plugged in to see if there is any connection. The AC jack may need replacing, if your lucky.

No power from my laptop .... cord has power but computer wont power up. No lights coming on computer or anything. Cord has blue light on .


Can you try to remove the battery then plug in the power cord then try to power on the computer, if it still doesn't work, call you manufacturer as you might be having a hardware issue.
The power supply may not be working on this instance.

Sound but no picture. menus work.


I had the same problem. In the menu, the image button was grey, and could not be hi-lighted, and the screen stayed blue. I was using the AC power cord. I plugged in the DC power cord instead, and it "woke" the unit up. I switched back to the AC power and it works fine. If you don't hve the DC cord that came with the TV, try andy 12 volt dc output cord with a positive tip.

Television does not turn on


please check the ac plug at the wall and also behind the tv. most newer tv's have a cord like a computer that plugs in the back and they sometimes come loose. are the rest of your electronic components working ? if the ac cord is plugged in, your power supply inside the tv has gone bad. you cannot blame your 2 year old if this power supply has gone bad, this was "NOT" caused by playing with the remote control.

Viewsonic monitor VG2021m won't awaken


I understand the vg2021m has a 3 year warranty. Phone number for Product Support is (800) 688-6688. Give 'em a call and see if they won't fix it for free or some nominal charge. (OK! So this is the cowards way out.)

The power cord easily falls out on my model, try twisting the power cord where it plugs into the TV until the red light comes on in the front.
