Screen Warm?

**askthefool** · 06-08-2004, 04:44 PM

I finally got my entire system working. I used it for about an hour, and when I got home and felt the screen, it was a bit warm?

I'm using a Lilliput. Is that normal?

Yes.

Bump for more answers. I want to make sure I'm not pushing too much power to it or something.

It's an electronic device, so it will get warm. Just like a home monitor and a television. There are components inside that will release heat.

Where is the monitor installed?

what voltage are you supplying it?

Yes they get warm.

yes.,aSH,. thats normal.. if its in direct sunlight, that add's heat too..

I'm in Arizona half the year, my screen gets hot too!

at the moment it's my inverter which is getting too hot.

should be gone later in the year

Its normal, much of the heat is being generated by the CCFL (or is it CCFT?) supply - some heat is generated by the flourescent bulbs - you should notice the right side of the panel to be the hottest - right where the inverter is on the PCB.

Future plans to beat the heat.

Plan A - mount a fan to blow in that area - not sure how well it will work, maybe a peltier cooler? Nah, they generate more heat than they suck up.

Plan B - buy a CCFT inverter from JKL - remote locate it so it is slightly further away from LCD panel or use combination of insulation and fan so LCD isn't cooking. The wires between the inverter and the LCD backlight are high voltage AC, so I want to use Silicon wire and keep them as short as possible so they don't propagate AC electrical noise everywhere. I'd also have to hack into the VGA controller board and cut the power to that section of the board, otherwise it will still generate heat.
