Question about Mag Innovision LT782S 17" Flat Panel LCD Monitor

1 Answer

Screen goes black after a few seconds.

Mag 700p. Problem comes and goes, but happens a lot. Power light stays on steady green.

I've looked at the boards mounted on the back of the case and everything looks fine--no bulging caps, cold solder joints, etc.

Any ideas?

Someone mentioned that a NPN transistor is often the problem; which component is it? Is it the one located next to Z201?

Thanks in advance for any help.

When the screen goes black shine a flashlight on it. If you see a dim image the back light needs to be replaced. Otherwise check the inverter as that may be causing the problem as well.

Hello,

The picture board on your monitor is bad, since it goes off after few seconds and the power led or button is on, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer or service center within your vicinity to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

Monitor comes on, I can see everything perfect then goes black


"Most" newer monitors will let you know if the are no longer receiving a signal. Sounds like the backlight is burnt out. Try getting a bright (LED works best) flashlight and shining it at the screen at all angles to see if you can see any of what you were doing. If the backlight is on the fritz, either return it on warranty or buy a new one.

Monitor goes blank less than a second after turning on.


Beautiful screen, lasts about for a few minutes, goes black. Power button still green. If I turn it off, and then back on, it works again for a while. Any ideas?

My Sony comes on then both sound and picture goes black.


After being on a little while, the screen goes black (no audio as well) for 20 to 30 seconds. Green light stays on. Then, picture comes back on and takes a couple of seconds to get up to full brightness. About 5 seconds or so after the video comes back, the audio returns.

Until this morning, has only happened a couple of times a day, now happening more often. About 3 times in last 20 minutes.

KDF-E55A20 is about 3 years old.

MAG Innovision LT1919WDb flat screen goes black


I had the same problem. I contact the manufactuer and they refused to fix it. They said it would cost an additional $100 to have it fixed. I have not even had it a year. I thought products sold in America were suppose to last longer than a year? What has happened to companies standing behind there products. Beware of this monitor!!! DO NOT BUY IT!!! LT1919WDB
