Try to unplug the tv for 3 - 5 minutes remove and plug back in the video cable and turn it back on. If that would not work call the tv 's manufacturer to have the tv replaced or repaired. If this would not work try to remove the video card and use an eraser to scrape of unwanted dust over the metal part of your video card that touches the metal part of the video card slot, for the viceo card could have a weak signal so doing so will increase the data connection. If this do not work still call the manufacturer to have it warranted.

The moniter blacked out, blue light is saying the moniter is still on, but screen looks like there is no power. When you turn on the moniter, the screen shows up for a few seconds, then blacks out again!...


Unplug power. Unplug VGA cable. Remove back of monitor. (four small Philips headed screws along the bottom rear. Remove screws attaching Monitor to it's base. Carefully, lean the screen away from back of case. Gently unplug 25 pin cable from the screen.
Connect AC power.
Screen should power on Gray to White. Ble light comes on Blue.Flickers then changes to Amber.
Reconnect VGA cable. Monitor should work.
Close up the monitor in reverse order to opening it.
If these steps don't solve your monitor, consider replacing as cost of repairs may shock you.

The montier turns on then turns right off


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...

Even if i switch on my computer with moniter it doesnt show anything on moniter screen it remains black


Hello. With the computer and monitor OFF, disconnect the signal cable from the video card on your system. Next, turn on the monitor. There should be a bright green box with a pink outline of a video connector inside showing. If there isn't, and the monitor is definitely powered up, then there is an internal problem. If there IS a little green box, etc., the video card in your system is suspect.
  • 1) When turning on the monitor, do you hear the sound of the high voltage initiating?(i.e. you should hear some type of electronic noise like a vibration or crackling of static on the picture tube)
  • 2) If you do hear that high voltage kicking in, it may very well mean that the picture tube is dead and getting a replacement monitor is in your future.
  • 3) If you don't hear the high voltage, quite possibly the transformer that produces it(called a flyback transformer) is defective.
Due to the vast array of inexpensive monitors available, you probably should consider getting a new unit--the cost of a new display will rival the cost of the repair--and you get a fresh warranty to boot. If the picture tube is gone, there's no choice.---Rick

MONITER LIGHT IS GREEN BUT ONLY SHOWS A NORMAL SCREEN FOR 1/2 SECOND THEN TURNS BLACK


HI. I had the same problem with mine. It would flash the screen on for a split second and then turn black, the whole time the power light remained green. Upon opening up the case, I pulled the combo power supply board/inverter board out for inspection. I noticed one of the capacitors had a bulge on top indicating it was bad. It was the the 680uf 25v capacitor. I desoldered it, and soldered in the new one. After hooking everything back up, bingo!! Monitor now works perfectly. I couldn't find an exact match to the capacitance locally, but I had a 1000uf 35v cap in my utility box. It worked fine as a replacement. You can usually go within 30 percent of tolerance and be alright. Just don't go under on capacitance or voltage. I hope this helps.
