hay guys, had a couple questions..

1. difference between a 6 and a 9pg xtra.
2. i know you can do the 6 or 9pg plus to 10pg board swap
3. can you do a 6 or 9pg xtra to 10pg board swap?

i have my 10pg still, i have a set of 6pole magnets for it. and i want to take it to an xtra if possible still has great tubes and its lives on the floor of my laundry room.

thanks guys

and hope to see ya saturday.

You can make a 10pg plus, but not an extra.

To make a 10pg into a "plus", you MUST swap the system and video cages. Then re-use the gain and video output board from the 10pg to keep the CRT calibrations. The System cage swaps to all the plus boards, as well as the F-drive AND connection cable between it and the system mother board. (one extra pin on the plus F-drive) The deflection board swaps as well. Unless you cam make franken-yokes, the dcpc board won't be used. It doesn't need it.

I did this to my own PG10 (Runco990) and I think it was worth it. In particular the ability to really fine tune the convergence.

The Xtra uses different tubes and neck boards which will NOT work with the PG, PGplus and PG10 tubes, so that's out. The deflection board is also different. In fact, most of the Xtra is really a different projector inside. As you already know, the PG10 is just a PG6/9 with bigger tubes that are pin compatible.

You will keep the original power supply, HV supply, C-drive, gain and video board and the front input board. You CAN use the plus gain and video boards, as they are actually the same, but your reference white balance is stored in the PG10 set, so keep them if you can.

Then just do a white balance adjust using the menus in the "plus" system. Mine came right in by hitting kelvin and store.

Good luck.

I'm trying to make a 10PG plus from a Runco 990, I have swapped out the required parts, the projector starts up and projects a signal, but im not able to get the I/R remote to work, and using a wired remote, it will only except one command per minute.. it seems that there is a huge lag. any ideas....

Thanks
Leonard

Did it work before you started modding it?

yes,
I think Im screwed now, I did an eprom reset and now i don't get any menues....

I've never done an EPROM reset on a PG, so I'm afraid I can't help. try putting it back to normal.

Have you tried CTL+Display on remote? Also there is a switch on the SYSTEM board that disables the OSD, might worth a try

I bought the 990 5 years ago, bought it working. it sat for a year and when I went to set it up, it when up in smoke. several years later found a 9PG+ and swapped out the system cage and the video cage, tested it and it worked, I then stored the PJ intill now , when powering up I found the ir remote would not work, I used the wired remote but i have to hit the buttons serveral times to get any menus. May take 30 to 60 secounds to get a response..I though maybe a eprom reset would clear things up but now it just powers up, tubes light up with signal, but no menus on screen now. The tubes and chassis only have 450 hours on it, so you can see why I have not giving up and part it out..

If some one can tell me the board #'s that where in the 990 originally , I could have a new start point, as I may have mixed up the boards.
the donor PJ was a Runco 900 I believe.

You did not mention that if you changed any caps in the unit. Unfortunately the older plain and plus PGs suffer from serious capacitor leakage these days. Basically you'd have to change every single electrolytic capacitor in the PG. If theleaking caps did not cause already PCB trace damage, the new capacitors most likely bring back the unit to normally functional state. Leaking capacitors in the PG can cause every problem you can imagine. If you good at sodering I'd definitely would recap the set, or find a burnt tubed PG xtra, those do not suffer from capacitor leaking yet, but is more problematic to upgrade to 10PG xtra too.

You need to spend about 15 hours recapping every board in the set, and even that doesn't guarantee that it will work. gjaky is right, the caps leak all over the place, and I stopped supporting PG sets about 4 years ago due to nothing but problems with them. The hour count (or lack thereof) has nothing to do with the reliability of the chassis, it's simply age that is causing the capacitors to leak and damage the PC boards beyond repair.

I have Tinmans 10PG+ now and I can tell you it really throws a beautiful picture and having those extra adjustments is great.
This projector is amazing but I imagine that as Curt says recapping is a bitch.

I can't help with your problem sadly as I have never had to really do any work to my PJ. Curt came by and fine tuned it a couple years ago when it was in the ceiling of my last home.

Forum member Zolzar did a full capacitor upgrade to his -then new- 10PG he got a few years back, if nothing else he may can help you with a capacitor list.

The good old recapped 10PG is still running well. Rock solid convergence and a very sharp picture. Here is the link to the cap list. Definitely worth the time.
