Argh. Dell E172 TFT help..

Sirbendy · 23-09-2008, 10:22 AM

I've got an E172/173fb 17" TFT screen here that's fully operational, BUT...when it's at a "no input" state, it does the RGB colour cycle thing...looks like one of the kiddies poked the hideen Tech service menu.

Anyone got any ideas about how to get it back out of whatever self diagnostic it's in? It works fine, as I say..but the cycling is quite irritating!

I've got to tear one down later as well...they really are nasty cheap things..we've got some with degrading TFT panels, and others with popped electronics. I'm combining good panels with good electronics to make good kit out of bad.

If all else fails, I'll try swapping out the genesis display logic PCB with another one.

Cheers!

Are you using DVI or VGA? Try chaging the monitor input from auto to either digital / analouge.

Also I take it you have locked down the monitor menus / buttons?

it's news to me that you can do that..heh..

These only get VGA inputs. I've got one in front of me now that I'm contemplating putting under the knife...looks like this one has an iffy inverter.

Have you tried a new VGA cable? Also press and hold the menu button for 30s to lock the menus.
