Hi, someone know where can I, find tech manual for repair the PTV in my Sega Wave Runner,? thanks for any help you can give me.

You should just point the remote at the screen... the sensor is usually inside.
I've had the STK ICs go bad which cause convergence problems, although my Waverunner monitor was actually dead because of a large resistor (0.18 ohms I think) on the convergence board being open. I misread it, replaced it with a 1.8 ohm, and I got bad convergence, then realized it was supposed to be 0.18, and everything was fine.
Here were my threads:

and

Oh, and reading back through my thread, I see my remote didn't work either.
That group is a great place for information as well.

I'm not sure whether Mouser has the ICs, but I know MCM has always had the ones I've needed. You just gotta be careful, I always hear people talk about bootleg or no-name branded ones basically being junk, where they either don't work to begin with, or fail after just a few minutes. I think I got one of them before... I had an older RPTV with a convergence problem, I replaced the IC with a cheap one, it looked good for a few minutes, then went out of convergence again after a few more minutes.
I don't think I would socket it though, I believe there's quite a bit of current running though those pins. When replacing them, for some reason they seem tougher to desolder than a standard chip, and the traces seem to lift easily, so just be extra cautious.
