Hacked up TV Universal Remote Question

<< < (2/2)

ChadTower:

He's been working on this issue for a while now, tried a couple of different approaches.  The main problem is that the TV power on signal circuit for this TV doesn't really fit the requirements for this project without a fairly advanced hack that he isn't capable of doing yet.  Not to say he's incapable of figuring it out, mind you, he's definitely acquiring the skills as he goes.  But this TV has been more of a PITA than a TV has to be.

If he just wants it done, get another TV with the easier type of circuit.

If he wants to learn as he goes, he's doing a good job of keeping at it.

Keep on trukin man.

I had a similar problem(i think) with my tv.
I made the mistake of glueing in the supports when i put in the tv.
So when i later realised i had to do something with the power switch, what a pain.

The buttons on the tv looked they pushed straight in. After cutting the plastic away, the buttons inside on the board went down. Kind of an "L" shaped thing on the back of the exposed button.

The buttons on the board had four pins each. Kinda wierd i thought. So i soldered one wire to each pin on the under side of the board since i couldn't get to the pins between the button and board.
After trying a couple wire combos, i figured out which two turned on the tv.
Done.

Another option would be:
I'm not sure what the IR is that you are talking about.
But try and move the remote sensor eye thing on the tv to a different place. Just by extending the wires to the eye, you should be able to move it where ever you want it.
Try putting it behind the glass of your bezel. Or drill a little hole in your CP box just big enough for the little eye.
Then you could use your remote from outside the cab to turn on the tv. With no hacks even.

You could send me a pm with a pic of your board and i might be able to tell you where to solder.

Hope i could help or give you some new ideas

What about hacking a little 3v transformer to the battery compartment so it never "runs out of batteries"?  The transformer would need to be plugged into an outlet that's always hot, of course, and would still lose the code in the event of power failure...
