Turning the TV on with the computer via a relay??

It's almost certainly a momentary contact switch.  The question, I guess, is how many contacts it actually has.

The description makes me think it's a two seat momentary contact switch.  It only ever makes contact momentarily but it can be pressed in or out so a person can see if the TV is off or on.  Why they couldn't just look at the screen, no idea.

Trace the wires back from that little PCB and see if maybe you can't just short whatever it is connected to to keep it on.

I'm not at the same place as my cab at the moment but from memory...
The PCB only has 2 sets of wires coming out of it. one red and black and very thin which connect to the PCB near to the connection for the LED and IR receiver which I assume are 5V or maybe 12V and another much heftier pair which go to the main PCB which muct be the main power line.

I was thinking initially of just bypassing the little switch PCB entirely and wiring the plug to these two wres but if this doesn't also bypass the 'need to push the switch while the TV has power' thing then i'm up a suspiciously brown creek without a TV.

ChadTower:


The TV isn't running on 5v or 12v.  You should be able to get an idea of the purpose of those wires by their gauge.

I'd trace what is in between those two hefty wires and figure out what that stuff in between is doing.  It's possible you can just short those two lines and bypass the need for the switch.

I'm sorry, I don't know gauges. They are the same thickness as the wires coming from the power button of a computer... thin that is.

I'll have a closer inspection of the PCB tomorrow but the back side of the power button has a hulking great metal cover which blocks everything from view. I thought I had a photo but it seems to have dissapeared.



releasedtruth:

Any reason not to just use a Bits Limited Smart Strip? I mounted a hidden momentary switch and when you press it the PC/marquee/leds/TV/amplifier all come on and when the pc powers off, it all goes off. Plus it's a super nice surge supressor.  But yeah, looks like that would work :)
