My monitor is a 19" Envision LCD widescreen. It's brand new, barley 7 1/2 months old. About a week ago I was on my computer and it went black on me out of nowhere. I heard everything in the background still and all the lights indicating the computer and monitor is on were on. I turned the monitor off then on again, and it showed everything perfectly until about 2 seconds then it just went black again. I tried this monitor on a completely different computer and it did the same exact thing. I took out my video card, still did the same thing, re-installed drivers, still did the same thing, restarted my computer, still did the same thing, changed power cords, still did the same thing. I'm sure that it is not my computer and it is the monitor. I have no viruses and haven't tampered with my monitor in any way. It sits in the same spot as it always does, has never fallen, had anything spilled in it, is not kept on all day (I turn off my monitor whenever I'm not in front of it) etc. It happened out of no where and I'm quite upset since it's pretty much new. Can anyone tell me what this may be, how to fix it, approximate costs, etc.?

Hi there,

well tell me the screen isnt on warranty ? if it is then go to where you have bought it and then change it there. if it isnt on warranty then sometimes lcd screen gets spoilt when there is humidity thats the disadvantage with lcd screen and also if there is an inteference zone nearby. as for the repairs i cant tell you exactly as i dont know the degree of damage inside the lcd screen. but repairing these screens is somewhat costly and its better to buy another one.

hope this helps

Hi all,

My suspicion is that this is a capacitor problem. If the screen is turning off every two seconds or so and then it comes back for another few, that could mean that the capacitors are not charged (or in other words, the capacitors are not able to retain the charge long enough to transfer it to the other components).

My suggestion hence, is to isolate the power board (the one that has the socket for the power input), check if any of the capacitors (the tall cylindrical structures) have bulging tops, if they do, try to replace them (Novices please bear the polarity in mind when you play with capacitors) with ones with higher rated ones (especially the voltage rating, normally these would be rated for 25 volts, so try getting one that is one step higher.TYGA

I hope this helps,

Pls Get back with your views...

I had this same issue. For 3 days, I recycled power to get it come on - up to 25 times! For the first day, it would shut off again after some minutes.

But after a while, it would take less times to get it to stay on AND it would stay on longer.

By the 3rd or 4th day, it works just fine again - no problems. That was 2 weeks ago.

This all started when I powered down my monitor off for an evening, so now I've decided to leave it on all the time.

So there is hope it can heal itself.

It's the LCD's Inverter ... you have to replace it for it to go back to normal again... believe me inverter is the crook. i repair lcd monitors that's why i know the problem.

I to have this problem. I changed out my monitor with another one in the house and it still goes black. Only solution was to keep turning it off and on until it stayed on, praying the computer don't turn off. Unfortunately it did....any advice?

I also have dual monitors and I started having the same problem after i hooked up my back-up drive, I had to keep restarting and restarting, i finally decided to unplug the power cable from drive and i haven't had a problem since. My recommendation is to go buy a bigger power supply
