|
|
I recently got a free Runco DTV-1100 projector. It has 3500 hrs on it. The green tube has a 4x3 wear pattern on it.
The guy who owned it watched soap operas off of a vcr on it believe it or not. The red & blue are near perfect.
My question is does anybody know the approximate cost of a replacement tube? The tube says P19 LBD 03HKA on it.
How hard is it to swap out? If switched out tubes in in a non-LC before but this is new to me.
Last question is I currently have a Ampro 3600HD with basically new tubes that I have used for the last couple of years.
Should I just leave it as is or is the hassle & cost of retubing (not to mention hanging) the Runco worth it?
Thanks
Gary

I'm guessing the tube will cost anywhere from 500 up,I've been looking for a new or good green p19lug on the cheap but to no avail,I can't justify spending 1k on a new green considering what I paid for the set, hopefully tou will have luck in your pursuit.
Changing the tube is bloody easy,providing the new tube has the lc hardware attached,should'nt take nore than an hour to remove and replace.

At this point VDC is your only choice. $1695 last time I heard. YOu're NOT going to find a good used green tube, they are the first to wear. If I had 10 here right now, I'd personally have sets to put each one of them in.

First off congrats and when did it start raining Runcos? There seem to have been an amazing number showing up in the last month.
As to the hassle that is your call. If you have done swapping an AC tube then an LC tube is no harder. Barco's are very easy to work on and the 1209s service manual is floating around the web if you look hard enough. Finding a good used green is going to take nearly as much luck as getting a free Runco so maybe you will find one  . If your 3600HD has the higher resolution 8" tubes (white/white insulators) then you would might be surprised how competitive your 8" set is. Only you can decide whether it is worth the hassle and $1600. Personally for me it probably wouldn't but I am not as picky as folks here are (I got a Barco 808 with new at the time now 500 hour higher resolution P16s). Personally I would set it up and decide for yourself burned tube and all.

Ok, maybe this discussion is a little off-topic, but here it goes:
You should look at it another way: If you just buy a new 9", the the price for a perfect picture can still be considered low. You will even increase the price performance ratio of your system. At least this way of thinking gets you somewhere in the quality game and gives you much, much more satisfaction.
Another tip for anybody getting a projector cheap these days: Get it properly calibrated and you will have a picture that is five times better (just a figure). After a calibration the price/performace ratio of the system is higher than before!
The total price for your system may be still very low considering the quality picture you are watching. The price performace ratio of your system only gets higher after a calibration if you got your projectro cheaper!

Thanks for all your input. I kind of figured that the tube would be somewhere north of $1500 so I just have
to decide if I want to dump any money into it. I also have a G90 floating around here with a burned 16x9 raster
so it's usable- it's just very flaky and throws codes about every 10the time you turn it on.
secstate-could you elaborate on the higher res tubes with the white leads? I haven't looked inside the 3600
for awhile but I think they are red.
Also if I decide to keep the Ampro are these HD-120 lenses on the Runco worth swappping out with the HD8's
on the 3600? They are not color corrected. I realize they would need an adapter. Just a thought
Thanks again

I was referring to the ceramic (glass?) insulators inside the neck of the tube. You will see two long insulators on either side of the gun within the tube. If they are yellow/white they are the lower res most likely 180DVBs. If they are white/white usually they are P16s but sometimes PT18 then they are higher resolution tubes (smaller spot size). The difference in my Barco 808 going from 4500 hour 180DVBs to new high res P16s was night and day even though the 180DVBs had clean phosphor. Now how much was due to the high res nature of the p16s and how much was due to the fact the tubes were new, I don't know. But hi-def looked a LOT better with p16s (both 720p and 1080i). The higher res tubes were standard on later models of the Barco 1208s and Cine8 (later models). Some Ampro models came with them from the factory. In fact my P16s were for an Ampro retro unit.
The HD120s lenses are for liquid coupled projectors and, in any case, would not bolt to your Ampro 8" set anyway. The color filtering in the Runco is in the C elements not the lenses in any case.
Since you have a G90 floating around as well I might sell that and the Ampro to fund the upgrade to the Runco. All depends on how you value your time. One thing to keep in mind is that these things are depreciating so you want to figure out which one you want to use and then sell the rest while you can get $$$ for them if you care.

Honestly, unless the tube wear is way too small of a tube area (like it is with NEC's alot) or really bad, I'd set it up as is instead of spending the $1600 for a new tube and run it for a few more years until digital gets even better, then swap it out with a CIH set up.

Well, I had a 180 tubed Barco with a new green tube and a P16 tubed barco with a new green tube (and the red and blue tubes had about the same number of hours) and I can tell you that the P16 tubes were WAAAAY sharper. Now, in my case, the variable was also the chassis (1208/2 vs. Cine 8), but the chassis mostly accounted for lack of noise and such, I think most of the sharpness was the tubes.

This is a picture of a 90 IRE raster. It is not precisely converged and it it being projected on a white
wall- but you get the idea. I think in you would notice it in normal use. The projected image is 110"
diagonal which is the size of my screen- so the burn in is pretty much to scale.

Yep, it was set up incorrectly and way too small of an image area. That is why I said "unless the tube wear is way too small of a tube area" which in your case it is. You are in a pickle--depending upon how much you paid for the PJ. If you paid much less than $1000, then probably worth retubing. If you paid much more than that, then retubing may be the only option--but I wouldn't be happy about it. YMMV

Gary got it for free Dave, he is a total bastard.
However, unless you are a CRT pj freak Gary, like us, it may be simpler for you to sell it on, it's going to cost you $1500+ and lots of work and learning to get it up and running.
Depends whether you are up for it

I've got a line on a Barco 1609 in Phoenix for little enough to make shipping compelling... The LC chambers SHOULD be the same (don't quote me!) but tube and operating condition is unknown.
So far the seller has been non-responsive, which did not bother me as my sister and bro-in-law can't store it for me anyway. Should the seller re-appear you wants I should put you two together?

OK, for free, I'd go for it. It is alot of work, and it is a pain, but if you like the look, you'd have to spend at least $3500 in the digital world to be in the same class of machine. So, $2000 for that picture is pretty good! So it is what you are up for.

Well I just got my HD Fury II today so I think I'll go home and throw it on the Ampro and see what it looks like. I might get
ambitious and set up the G90 at the store and throw a Bluray on it and see how that looks. Maybe the raster burn on that is
livable.
I am sort of a CRT freak. I've had a Sony 1001Q, a D50, a G70(which went belly up) my current 3600 HD. Now I have this
Runco 1100 and a Sony G90 sitting next to me. The best part is I have never paid for any of them. I still have all of them
except the G70. I have 3 more customers out there with G90's that I'm waiting for the call to replace them with a digital projector.
