Re: Keeping back lite on without signal

Mind you I wouldn't mind leaving in the logic board - but without a signal it still goes off after a count of 10.
makes you wonder....

thanks PlainBill - trier with logic card connected just the on/off cable cut didnt make any difference.

Re: Keeping back lite on without signal

That was a big help.
did as you suggested, ~ 3volt on the Bright and 5.1 volt on the on/off - arranged that - 1 quick flash then off.
thought to self, perhaps there should be time delay on the on off, so organised that with 1uf tag tantalum and diode with cap to +5 and diode to gnd on/off to junction, no diff.
Just tried waiting for count of ten and connecting on/off to +5 with a 100 ohm resister, comes on for count of 5 then off. Reconnected logic board and computer stays on.
Knew a girl like that once - but only...

Re: Keeping back lite on without signal

Thanks for the reply PlainBill
I have an 8 way cable between "logic board" and PSU/Inv it has 2 Vcc 5volt, gnd, on/off, bright, gnd, volume, mute. so between the on/off and bright perhaps?

I have a 17" Acer AL1717A LCD screen with a cracked LCD! I have removed the LCD and it makes a terrific Lightbox for viewing slides - however as there is no signal the lights go off after a short time. Can any one help me with a workaround to cheat it into thinking it has a signal.

Thanks
