[QUOTE="Kash007, post: 521208, member: 34373"] Hi all. New to the forum so thanks in advance. [B]Scenario[/B]: Tv with usb output > (5v to 12v adaptor) > 12v trigger used for opening and closing a motorised tv brackets [B]Situation[/B]: Tv on = tv bracket opens as expected Tv off = tv closes after prolonged period of about 3 - 5 minutes I believe this is because of the residual power being present and fading after this time. Because of this residual power, the signal to the 12v trigger is still present hence the bracket stays open. My question is, is there anything I can put in line to kill any or dissipate any of this residual power to close the circuit much quicker? Ideally I’d want the bracket to close as soon as the tv is turned off. Unfortunately it’s a stand alone tv with no amp or any other hardware that has a 12v trigger built in. The bracket does come with a remote control but I don’t want to have to use another remote if I don’t need to. And buying an ‘all in one’ programmable remote control is another solutions but an expensive and long winded one. The Current set up nearly works perfectly - it’s just the delayed closing that’s not ideal. There’s no setting on the tv where I can specify Usb Power options on the tv either [/QUOTE]
