Thanks for the info Curt. I have a G90 here that sounded like it had a similar issue. That is until you described it further and it's not the same problem at all

Thanks, Curt, do you mean to take out the HV splitter and the PA board and send them to you?
May be I should first take it down from the ceiling!

You can do almost anything on the G70 and G90 without having to take it off the ceiling. Hopefully your ceiling isn't so high that you need to be on a tall ladder... I hate that!

I removed all three RGB HV lines and the error code 33 is still there. And then I think I'd better try to remove the HV line from the HVPS and the eror code is gone but of course without the HV, there will be no light in three tubes. And after I reconnect everything, the error code 33 is still here.
Just a side note for someone who would try to unplug the HV line from the HVPS, without discharging via the tubes, beware the HV can stay long! I have removed power plug for over 10 minutes before plugging the HV line back, the spark still scared me like hell!
So then, back to my problem, Curt, excuse me for my unprofessional guess, can I assume it is the Splitter fault or it can still be the PA board? Do I have to send both or just the Splitter to you?

correct, the "empty hole" is all the way towards the back of the splitter and it's actually not empty, should have a silicone cap over it.

In yet another stroke of Sony Engineering genius you need to remove the Blue tube in order get the spliitter out . I just looked and there's a ground wire to chassis directly under the blue tube and there's also the Gray wire bundle back to PA board which would be hard to manipulate with blue tube in place.
I have a couple of extra splitters here that I know for sure don't leak if anyone needs one. $50. delivered to US.

I would send both parts in for testing. I've never had a splitter go bad, but it's possible I guess.

Yeah, I figured it out the hard way. I have tried everyway to take the splitter off without removing the blue tube and finally I have to bite the bullet and remove the tube.

Yeah, but the tube is pretty easy to remove.
Can you not try a new splitter by just hooking the HV wires to it and letting it dangle from the projector? If it solves the problem then you can actually pull the splitter and swap it properly.

I haven't thought that! So the HV lines from the HVPS is actually the same voltage as the RGB HV lines? And how about the control lines from PA board to Splitter, will that be the killer as well?

You are confused.
Nope HV= High Voltage 34 000 volts. Nothing to do with the RGBHV. That's Red, Green, Blue, Horizontal, Vertical
Thosw lines are completly seperate. They cary 0.7 volts max on the RGB video and 1 volt max on the H+V lines.

No, by mean of RGBHV, I meant the R High Voltage, GHV and BHV from the splitter, definitely not the analogue signal RGBHV.
