Possible LCD monitor heat problem? - Tilted Forum Project Discussion Community

BulletCatcher · 04-14-2007, 06:12 AM

I have a Sceptre X22WG widescreen LCD monitor and have been having a bit of a problem with it lately. If the montior has been on for awhile it will just go blank. The time it takes to happen depends on what I'm doing. If I'm just working or surfing I can have it on for an hour or two before it goes blank but if I'm playing a game it will happen within 10 - 20 minutes.

It doesn't shut off as the power light is still on and it is still recieving a signal but the the display is all black. If I turn off the monitor and turn it back on the display comes back but only for a few minutes before going black again. At first I thoughtit was a cable or driver issue so I attached a new DVI cable and updated the vid card and monitor drivers and the problem went away for a short time but 2 days later it stared happening again.

Upon further investigation I noticed that the vent slits along the top of the monitor are very warm to the touch when it goes blank. I rigged a small fan to blow into the slits yesterday and have not had a 'outage' since leading me to now believe the problem is heat releated.

I've done some searching but am unable to find any information on heat issuses for LCD monitors so I guess it's not a common problem to have. I've only had this monitor for a few months so it should still be under warrenty so I guess I could RMA it for a replacement if it's defective but would really prefer not to have to go through the hassle especially if I'm wrong. Has anyone else ever had a heat problem with thier LCD monitor? If it is a heat issue am I ok with just having the fan blowing on it or should I just send it back if possible? If it's not a heat issue then what else could it be?

It does sound like a heat related issue. I have a 19 inch Acer, and it NEVER gets even warm durring heavy use. Sounds to me like something in the unit is having electrical current issues, and that is causeing it to get hot. I would atleast CALL the manufacturer and get a potential RMA case started. It might be a common issue that the manufacturer has, but without asking, you will never know. Good luck and let us know what you find out!

sounds like heat, start the RMA now, and good luck getting one with Sceptre. if that doesn't work, strap some fans to it and good luck.

BulletCatcher, where is the LCD placed? Do you have it mounted to the wall? I have 3 of those units and they do get very warm. I used to have them mounted onto my wall in front of my desk, but that caused the heat to get trapped inside the units, and they'd go blank. Just like you're referring to, make sure there is nothing blocking the back or sides of the units. If it still goes blank, take Dilbert's advice. RMA's are not easy with Screptre.
