Samsung T240HD/black screen help...

[haiggy]

Hi there,

I purchased a Samsung T240HD monitor a few years ago and have been using it every day since. Recently I have run into a problem where my display will not turn on every time. The power to the monitor turns on however the backlight does not turn on (if I shine a bright light on the monitor I can see a very faint picture). This only happens some of the time though. Some time it turns on fine, other it just stays dark/black. I have tried googling my symptoms but don't seem to find an answer as to what exactly could be the culprit.

Any body have any idea what may be the problem? Bad capacitor? Inverter? I think the backlight is fine as it works great WHEN the screen turns on. Any help?

Thanks!

Figured I would write back since I came across your post. I got one of these monitors almost 3 years ago and it is still working strong. Unfortunately my brother got one awhile after me (He saw me running the PS3 on it and fell in love) and his just died. Didn't even get the kind warning you're getting now although my laptop did what you are describing for white awhile before it finally kicked the bucket.

Pretty much what you're looking at is most likely a bad backlight. Sometimes it could be a bad power inverter but I shy away from that assumption. So you're either going to end up replacing the backlight yourself, buying a new monitor, or trying a more interesting approach. ( http://www.instructables.com/id/A-very-Simple-LCD-Backlight-Fix/ )

Too bad I got here a few days late because I would have just recommended getting out on Black Friday and buying a new one then. There are several guides on the internet for replacing backlights yourself you just need to look for them. ( http://www.inventgeek.com/Projects/shorts/OverView.aspx for example)

I have a T260HD. Sometimes it just doesn't wake up from sleep so I turn it on and off. I'm not sure if that is the same issue you're experiencing, though. Good luck!
