Here are the tubes on the pg6200 that I picked up a few weeks ago. They look to be pretty cooked and it would seem that the previous owner didn't set the raster size correctly. The blue tube looks to be workable, but the green and red look like they are toasty and brown. What would be the best course of action here?

Another thing that I noticed was that all 3 tubes needed to be bled badly. After taking the lens' off and turning the unit up on it's butt, there were no air bubbles moving around on the face of the tube. I have started the unit up once just to ensure that all 3 tubes were working, but shut it down immediately after that.

So, what would you guys suggest? The electronics seem to be in good working condition, and I am on a shoe string budget.

Honestly I would look for a different machine, it will likely cost more to retube that one, than it would to get one with clean tubes, I would look for the same model with good tubes so you have 100% backup parts, in the meantime I would use it as-is within the wear and live with the wear.

Where are you? I have three tubes from a 6200 that look pretty much the same. You can have them for the cost of shipping. Send them to VDC for rebuild.

are mutually exclusive, AND if you've ever seen the terrible quality of VDC rebuilds, I'd imagine you'd be a little more hesitant about recommending "rebuilds"...

There are lots of projectors to choose from nowadays, and they're all pretty darn cheap. Set up and run that burned NEC till you find a better condition, cheaper replacement. I'd bet even in their burned condition you'll have a pretty good image. I've had NEC's with at least as bad tubes as that and they can still make fine images...

Elaine is right, of course. I've no experience with VDC, but I believe they charge somewhere around $500 per tube for rebuild. $1500 to me sounds reasonable to me given I preferred my NEC to the BG1208 I have now. If it weren't for the plethora of other faults with my NEC, I would have sent my tubes to VDC.

On the other hand, I think you can get an NEC from Curt with good tubes for about the same. Which would probably be a better route.

Food for thought anyway.

I wouldn't spend any $ on the PJ.

I'd either:

- Find another NEC 6Xtra or 9Xtra with better tubes and keep this for spare part (some parts are interchangable between the 6 & 9)
- Get this one working for little $, set up the image within the burned area, live with it and save up for a better condition PJ
- Part this one out it you can't get it to work cheaply and save up for a PJ in better condition. The lenses alone use to bring a good price

Don't the 6pg and 9pg use different tubes or is it the same tube number's between the Xtra's?

I'm 99% sure they are the same tubes. Mainly the same boards. Just different firmware in the 9 that allows higher bandwidth.

I'm a green kinda guy, not alpha sprout eating eco terrorist green, but green none the less. Things have sure changed since I discovered this site just a few years ago. I just saw another thread stating VDC is no longer rebuilding tubes. This sucks. I loved my 6200 with toasty tubes and the complicated set-up. Damn, I learned a lot from that machine. Even with the toasty tubes it still had a great pq, except for white scenes which were brown or pink. A year ago I wouldn't have hesitated re-tubing it, but it happened to fail just as I found two BG1208/2s (one with brand new tubes in it) and a tab-tensioned motorized screen for next to nothing on craigslist.

I'm hoping once I get Craig here in the near to distant future and have a proper calibration that I will be as happy with my BG1208/2. I'm starting to think that by the time I get my HT done and am ready for a proper calibration that buying a 9" machine and not calibrating it will be more economically feasible and a better end result.

I miss the days when money was a factor in deciding which CRT PJ to get. Now it seems many of you are just biding time until a good digital comes out. That's okay, Lexx21 and I will still be watching our toasty tube CRTs and thinking we have the bee's knees in HT!

Correct. 6/9PG tubes = 8/9PG+ tubes = E8508.

6/9 PG Xtra tubes are the P16 that do not work in the PG or PG+.

Frankly, run the set as is. I might have a set of OK but not perfect tubes here, I know I have some brand new R and B, but they are $130 each.

You'd be surprised how good the pix will look, until you widen out the phosphor, and see the extra 20-30% brightness you'll get in the virgin phosphor area. If you can live with off whites, then you can get some use out of the set as is.
