| Posted: Tue Feb 10, 2009 3:15 pm Post subject: Has anyone successfully used old Barco EHT part in new Barco |
|
|
I recently acquired two Runco 1100s. They are essentially very late mode Barco Data 1209s. They have the newer EHT section. When I got the sets the owner said that one was "dead" and the other was his home theater projector and was working. I would like to test boths sets to see which one might become my primary projector. The "dead" set has a bad quad. I can swap the quad from the working set and the dead one works fine. The problem I have is that I would like to be able to run both sets more easily. While I don't have any new style quads I have plenty of older style quads and EHT boards.
I am aware of the service note that Curt has on the site that states you must change both EHT and Quad when moving from new to old. However I tried that with a known good old EHT board and a known good old quad and got no HV. It just did nothing (no EHT hold down light either). Looking more closesly at the service note "http://www.curtpalme.com/docs/BarcoServiceBulletin_R762716_New_EHT.pdf" there is a reference to a jumper that needs to be changed on the "frame." Quote "On the new frame there is a possibility to change the arrival of the DHV to either one of the above pins. A jumper can be removed and a new jumper soldered in the two other holes (note that to access the PCB the bottom cover of the projector must be removed....)"
Does anybody know where this jumper might be? It is clear from the matrix in that service note that new splitter + old quad + old eht + new frame = no HV which is what I saw. I am assuming that the "frame" Barco references is the "motherboard" that connects all the "daughter" cards together.
I am just trying to avoid swapping the new working quad between to projectors because it is something of a pain to swap.

You always come up with the "good" questions......
I remember seeing the jumper detail on one of the SBs - but do not remember where it was. Maybe Curt will trade old/new quads with you as the BG 808s unit he has should have the new quad....

Ah, you got those two sets! Nice score!
Shoot me an email to curtpalme@shaw.ca, I can offer you a few things regarding those HV sections...

If you are referring to the two in DC a couple weeks back then yeah, guilty has charged. I was surprised I got them as I was a day or two late from the intial posting and the guy didn't even respond to me at first. The you haul bit keyed me in and I made it clear I would show up with a friend and he wouldn't have to do anything. The really funny thing is you might remember the Crownsville projectors on Ebay and the reference to a employee taking the other two. Well these are the other two. The hours are highish but other than green the tubes look pefect. Green in both does show some wear and unfortunately in a relatively smallish area. Ironically I wasn't even looking for a projector but my RSS feeder that I use was still collecting hits for Barco projectors and these were close enough and cheap enough to interest me. I will send you an email. Thanks!

There is a jumper on the motherboard near the connector for the EHT. It can be moved
over to use the earlier type EHT. This can be done without disassembly of the chassis -
- if you have steady hands and some long locking forceps (hemostats) and don't mind
soldering in tightquarters, on the up side of the circuit board, etc, etc....(yes, I did it)
However - if the Quad is the only problem, you can run the earlier style quad long
enough to test the chassis. If you see excessive fluctuations in output then stop.
The tech sheet available here has all the info and a compatibility chart.

Thanks to Curt and Kal for all the tech info,

@Curt you have an email. All else being equal I would have gone for the 909s too, though I guess I can "slum it" with the Runcos .
@zGman thanks for the details I will check that jumper out. My soldering skills are fair.

Just to update this thread for posterity. A big thanks to Curt! Though he forgot to include the picture of what he was describing in his email to me, a study of the 1209s service manual made it clear what he meant. It is possible to modify the old EHT board to work in the newer projectors by soldering some jumpers on the EHT board which is easier since it is removable. So I now have an new old stock old quad and old EHT running my "main" Runco just fine. I didn't really like the new style quad as it was a bit noisy.
P.S. As I spent some more time with the Runcos, all I have to say is WOW! I had seen 9" sets before but never in my home theater with material I was familiar with. Even with my completly crappy temporary quick and dirty setup it is easy to see how much more revealing it is than my Data 808s.

Curt no worries. Without what you told me I would probably be trying to move that jumper and cussing up a storm. In fact I learned more about my projector by trying to figure out what you had told me so it wasn't a bad thing at all.

Secstate, how do you tell if your quad is old or new? What do you mean by a noisy quad? Was it squeeling a high pitch frequency you did not like? Was the jumper job pretty easy once you knew where to go? Do you know if a 1209/2 is old style or new? Do you know if a quad or eht from a Barco 500 work in an old style application?
I have a lot of old Barco junk but I am wondering which parts are really compatible.

Actually I have two units . Both are all LPBs. Other than green of course they are mint. I have a Barco Data 808s with the higher resolution P16s and I am actually shocked how much sharper the 9" set is over the 8". I am guessing it has a lot to do with the optics.

Tom posted the details on the parts numbers and that of course is the best way to tell for both EHT and Quad. For the quad they look identical but the plug for the new quad has one of the pin holes filled. So you cannot plug a new quad into an older Barco. The EHT is easier to identify as the PCB on the newer EHT is bigger and it has two LEDs on it rather than one. Once you see a new one next to an old one you can immediately tell the difference. All that said the part numbers are the easiest way to tell. Your quad and EHT from the 1209/2 should work with modification. I am using the same part numbers as would have been in a 1209/2. The EHT I am using is actually from an 808 and the quad is new old stock from a 120x series. So yes you 1209/2 quad and EHT are old style. The cutover to the new style was sometime in 1999 I think. The /E designation on a Barco means it came from the factory with new style HV section from what I understand. However it is supposedly less reliable than the older version.
The new quad made noise in high contrast scenes and on startup. It may have been partially defective. I was extremely lucky and got two Runco 1100s. One had dead quad and the other worked or appeared to. However it was noisy and it would periodically go into EHT hold down. I thought it was the quad and so I modified my old EHT and replaced the quad and EHT with old style. However it went into EHT hold down still so then I swapped the G2 Focus and Diagnostic board and that finally fixed it (that advantage of having two identical projectors). I stayed with the old style quad because the are supposedly more reliable and I see 0 difference in the operation of my projector.
The jumper is just a wire that is next to the quad plug on the frame or what I call the motherboard of the projector. It is pretty obvious. The 1209s service manual that is floating around on the net (thanks Tom) has the jumper clearly labeled but it would be a pain to get to from the top and a pain to remove the bottom of the projector. The mod that Curt suggested on the EHT board is a much better idea and allows you to use an old EHT in a new or old projector once modded (you still have to be careful not to mix and match new with old eht/quads). I did not post the details here because Curt gave them to me over email and I didn't want to make something public if he didn't plus the picture of my mod would show my pathetic soldering skills and I didn't want to publish that on a public forum. However if you or other interested parties PM me I will send you the mod instruction and a photo of my mod so you can understand what I did. It is very simple since even I can do it .

Runs upstairs to check......
LPB03 are in both units. What is the difference if any?

jkruger, a totally random question for you. What was the production date of your 1100? I assume it is the one in your avatar. The reason I ask is the Runco "artwork" on yours is different than my two which were made 5/00. My two just have Runco in gold lettering centered.

I don't remember what the date on it is, maybe 1999? Let me check my old posts, I'm sure it's in there.
Found it.
