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

He built his own smart strip.  The problem is the TV won't go on when power is applied to it via the relay (my crappy TV does this too, so I'm interested to see if this can be hacked).  The other issue he may have is whether or not the TV remembers the last input selected (AV1 or whatever).  Mine also doesn't do this.  :banghead:

Definitely a candidate for getting a different TV.

Hmmm..... now that he has mentioned that you HAVE to absolutely push the button to turn it on after power is applied it most defineately is a momentary switch.
Odd that it would have an IN / OUT detent like that though.
None the less, if it is momentary you might possibly try "holding" the power button down, as if you were turning it on, but don't let go..... THEN apply power by plugging it in. This should at least verify if it will be bypassable. (some require that you actually let go depending on the circuitry of the tv itself)

That is a problem I have but got around. The TV comes on to Ch1 everytime. I got a cheapie modulator from Jaycar for $15.https://secure4.vivid-design.com.au/jaycar2005/productView.asp?ID=LM3873&CATID=31&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=372 I just plug my AV cable into that, tune the channel into one of the selectable frequncies on the modulator and hey presto!!!!

now if only the TV would turn on...

I cant check untill tomorrow, maybe monday depending on how things go. but if it turns out that it needs to be pushed and released am I stuffed?

There must be a way around it...

Also if it is a momentary switch, will using the relay to hit it like I described in the first post of this topic kill it?
