Monitor shows picture for 1/2 second then goes black, 22" display. also will not show display menus. have hooked another monitor up and works fine. also have hooked up to another computor and problem remains the same. indicator (yellow/green power lite) shows it's getting a signal ie green lite... x2gen 22" lcd display

As I scrolled through your solution a smile began to creep over my face starting with "this can be lethal." Each picture frame I scrolled past began to formulate my strategy. Your instructions could not have been more clear and precise, detailed, easily understood. When I reached the last picture my plan was put into action. Off to buy a new monitor lol, you must have the patience of Job. Thanks.

There are two problems, screen goes black after 2 seconds, red only. The problem is in the video processing board located on the back of the picture tube, it is well shielded against outside interference.

Hi!
When a monitor display image for a second and then goes to black screen... there are possible reasons why this problem occur..

1. You need to check if the high voltage ballast transformer of your backlight inverter is about to be burned... the transformer is overheating..that's why you experience the monitor working for a couple of seconds and then it will shut off until the transformer cool down again and then it will be ready to work again...

2. Check also the backlight inverter if it is busted...the backlight inverter is the light source responsible for the image display you seen on your screen. If this are busted then all that you will be seeing is black screen

3. You need to check the power supply section for possible loose connections and possible blown and bad capacitors..

the ballast transformer has direct effect on power supply section.. when there is overheating transformer,,, the supply current from the power supply section becomes unstable.. and will not be able to supply the remaining good working ballast transformer.

In case you do not know, the ballast transformer generates high voltage for the backlight inverter to work....

Please be advise that if you don't have the knowledge, the proper skills and the right tools to open the back cover of your monitor and replace its part...don't risk it...

Otherwise, bring your unit to a credible technician and avail of warranty if there is any.....


Much appreciated if you rate this help...thanks...

Some 22" Viewsonics will have worn out bulging capacitors in the power supply that causes this symptom.
Monitor Mike

Chances are that some capacitors in the power supply have failed. some monitors are known for this. The parts are readily available, but they do solder in.

There is a symbol of Two monitors on F3 Or F4 button

1. Press Fn key and hold it
2. by holding Fn key press F3 key

Your monitor will start displaying

try hooking it up to another computer to ensure
it is not the graphics card that makes trouble...

if still the same prob, check the net if there are
known overheating problems for that model,
i personally recommend to see a technician, as repairing a monitor could make things worse...

up to u, good luck then

Your monitor has a bad INVERTER, look on eBay.

blown capacitors this can be fixed I can help or advise you how to do it but it will require soldering internal components.

Try connecting the wires properly. try changing the VGA cable. i had the same problem my screen goes black some times and pink i changed the VGA cable it was absolutely fine!!!
