Vx922 monitor will not come on every time.

Since you hadd confirmed that the monitor is faulty with a swap then it seems that the input signal processor is faulty.
Only a signal test will confirm the fault in the stage , so check from the power supply section to see if the set has tripped off due to a protection- if so check the output drivers.

The monitor shows no signal probably it didnt detect the tower
Ill be advising you to remoev the cable that conencts the cable
used a clean cot or rug clean both ends of the cable , clean also the area whre you plug in the cable , the ports on the monitor and on the CPU make sure its clean .
Then plugged it in , in case nothing happens
try to used another cable that conenct from the monitor to the CPU
you may aslo try to used other CPU to checked if monitor is working fine or try other monitor to checked if the port on the your CPU is working fine

sounds like the power supply inside of the monitor is going bad. did you replace the cable from tv to the wall?

check your graphics card. or try replacing your video cable.

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.

You may want to tey another computer or another cable or update your video card drivers. Otherwise look very closely and see if you are able to see a very faint image of your background picture or icons if you have any.

Really im not kidding it might be a backlight issue.

Really if this happens then you may want to contact viewsonic to see if it still in warrant. Reminder that most of their monitors have a 3 year warrany from the date of purchase. So make sure that you have your proof of sales/receipt/POP/invoice or what ever you want to call it ready. This model is old so they will ask for it if its a first time repair.

Get the RMA, I had no problems whatsoever with thecustomer service folks. They answered email within 1 business day, shipped off the monitor last week...

I have the same problem with my VX922 as do MANY others. The problem seems to be caused by leaking/bulging capacitors on the circuit board. The only solution is to replace the faulty capacitors either on your own (which is fairly easy if you're good with a soldering iron) or send it to Viewsonic and have them fix it.
