One day it went black, if I turn it off then on I can see a perfect picture for half a second


If this is a LCD monitor, most likely the invertor or the bulb is not working correctly. If you shine a flashlight at the monitor you should be able to see the image. What has happened is the back light is not lit to display the image. If you are handy at repairing electronics you can swap invertor and bulb from the other monitor if they are the same model and size. It may require some soldiering though.

The picture wont come on and the tv shuts off after 10 seconds then the stand by button blinks


the picture tube blew out you need to just replace it mine costs 250 if your tv is newer you might still qualify for free bulb replacement like i did but you have to have your reciept to fax to them so they can ship you your free bulb and then you place the bad bulb in box and return. the button blinks you need a new bulb they are good for 2 1/2 years if you keep it on always and use it for computer monitor like I do. but that is what your problem is.

Monitor will not come on but power light comes on


Based on the numbers of viewsonics I have repaired, It is probably in the power - inverter board and not in the video board.
Since it is a 17 inch, there is also a chance that one of the bulbs is bad, but that is less likely.
If you can take it apart and send me a picture of the board to [email protected], I may be able to see if the board has the obvious problems.

No picture on my x5g-komodo7 monitor


A reddish picture is the classic symptom of worn out backlight bulbs.
Sensor circuits usually shut down the power to the bulbs in a second or so.

Monitor blacking out intermittently


Monitor going black after a few seconds can be causd by a faulty power supply or inverter. Some monitors have both as one unit.
Sometimes it is basic failed capacitors, After that then I would look at transistors.
The average monitor from 17 to 20 and sometimes the 22s have usually 4 bulbs in them. One bad bulb will also cause the inverter to not fire up.
Bad bulbs usually show pinkish tint, or flickering or are dark at center top or bottom of the display.

Possible_backlight_issue


Hi goldeneye, Sounds like the backlight inverter board. Don't mind the explaination I just cut and paste this solution from one of my others. It's a very common problem. LCD's use four small Cold Compact Fluorescent bulbs to back light the display. (thats what gives the LCD it's brightness allowing you to see it) The inverter board runs these lights and when they go bad they will typically show symptoms like you have or the monitor power light comes on and you have either no display or a very dim display. If you ever have one that has no display but the power light is on you can check by shining a flashlight directly into the LCD from the front (right into the screen) if you can see an image then it's either the inverter board (most likely) or the CCFL bulbs have gone bad. The inverter board and CCFL's are replaceable. Good Luck, El Duderino
