| Posted: Fri Dec 12, 2008 11:28 pm Post subject: Marquee recall memories |
|
|
The projector and I have been at odds for a few days. When I hooked up the computer, I set up a new recall memory. Everything comes in the same source.... the 5BNC That used to be fed from the little transcoder I have that I use the DVD player and cable box. Now that I have the pc in the mix, I have an old kvm switch in place. The vga output of the pc to the switch, the output of the transcoder to the switch, and the output of the switch to the projector.
I still have to manually go change the component to vga cable from the DVD player to the Cable box when we switch between those, but they are both run through the transcoder.
I have three recall memories set, one for the dvd player, one for the cable box and a third for the pc. These are assigned to channels
Channel 1 = source 1, recall 1 (Toshiba HD-DVD ---> transcoder---->kvm switch-----> pj)
Channel 2 = source 1, recall 2 (HD DVR cable box -----> transcoder ------> kvm switch -----pj)
Channel 3 = source 1, recall 3 (PC vga out ------> kvm switch ------ pj)
I noticed a huge shift in convergence when I installed the switch. Went to each signal, put the projector on the correct channel for that device, and cleaned up convergence and saved, but I swear each time I switch between sources and call up the correct channel, the convergence is off again. My recalls are not locked. At this point, it also looks like it has messed with the electronic focus as well. the largest problems appear on the left side of the screen. The blue especially appears "bloomy" on that side.
Is there something I am missing? My convergence changes and saves should only be affecting the current recall memory I am using, correct? (so far I've just done touch-ups, I haven't zero'd out and started a convergence from scratch for the new signals I've added) while I am in any given recall memory, that should only affect that memory, correct? Or if I reset convergence, will it affect all memories?
I assume that if I go into the service menu and zero the green convergence that this affects any and all memories?
I think at this point, it's the best thing to do, if anyone has any advance advice, I'd appreciate it before I start in....
Thanks!

No, ASI is not on. I turned that off per e-tech's article when I first set up the pj

If you don't lock your recall memories after making changes, all changes are lost when you change to another source/frequency...

I cannot switch sources any other way without the kvm unless I physically move cables around. Not sure what you are asking me to test. The transcoder is just there to take care of the component signals and send out rgb. The input cable on the transcoder is always attached to it. Sometimes it's the cable box attached to it, sometimes it's the dvd player - it's a matter of popping the components off of one and slipping them on the other.
I have it warming up right now. It's my intention to do a complete convergence for each source on it's assigned recall then lock them and see what happens then.
I guess my main question at this point is..... what paramaters are linked to recall memory and what are global? Convergence and geometry? Is electronic focus global or per recall memory?
If I reset green from the service menu is that global? Resetting convergence while in a particular recall is NOT global... right?

Just to be sure I understand you.....
I'm not changing sources as the projectors sees it. It sees everything as source 1 because everything comes in the same 5 BNC. The signal from the dvd player and the hd cable box are both passed through the transcoder and are output at the same frequency.
I must have misunderstood. I was working under the assumption that locking the recall memories made it so you could not SAVE changes to them once they are locked. That they had to be unlocked to make and save changes, but I was not aware that even after you saved changes and switched to another recall, it would wipe out the settings you just saved. So you are saying that I need to lock all my recalls, then everytime want to make a change in convergence, I have to unlock the, make the changes, save, then re-lock them? It's never displayed that behaviour before and I've never locked the recalls and switched between recall memories quite often without it losing settings.
The way I've always understood it was that it would dump your changes if you did have it locked when you made adjustments then changed recalls or powered down.

Thats your answer right there, the transcoder is sending the same signal , your PC has different timings,resolution,front and back porches etc, you need to set up the recall for that and save it(lock it). The two other sources must have pretty close timings tec for the convergence to stay intact. But i bet they might be off a bit if you look close.
remember that CRT is a multi scan display and it reacts to its input frequency, so each input must have its own set up and then lock that in so it wont change. If you need to change it unlock it make the change then lock it again.

Now I'm about to be peeved. I went through all three, setup and convergence, saved to their individual recall memories, and locked each one after I was done before going onto the next setup. I completed the last one and locked it. Went back to one of the others, and its out of whack. Double checked everything. The recalls are all still locked.
It seems to affect the left side of the screen more than the others, also screws with the focus and geometry This is utterly frustrating.

Just a thought - checked your backup battery voltage lately? don't see how it could affect
since you didn't say you had powered down, but something is awry. Typically there is no need
to lock a recall memory to save the data, locking just prevents it from being overwritten.
Earlier question - RGB focus control is global (sadly enough - Barco is for each memory)
Convergence on green, including raster shift, should be for each recall memory.

Hmmm I wonder if its the Chips on the CLM need cleaning, Have you done this at all? As a quick check you can push down on al chips in the clm on a flat surface witha twel under the board. press on each chip until you can properly clean them all with Caig deOxit. Also check the voltage on the battery, it should be 2.5-3 volts.

I had not powered down. As for the cleaning. How often does it need to be done? I've had this one less than a year and I'm sure Curt had it up to spec before he shipped it. I have another for parts. I'd need some guidance as to what board I'd need to scavange from the other to see if that fixes the problem. I'm about ready to stick the input board in it from the other one and put the pc on that...

PS. I appreciate the help so far. I was just bragging on how trouble free this pj has been. Should have kept my mouth shut

I've been researching and found a few others who had this issue. Seems most people don't ever post back to say if they resolved it or not. Seems there is a lot of back and forth about ASI and ASR. I have verified over and over that ASR is off and per the readings on the E-tech site:
"UTIL, 1, 4 ASR On/Off: This toggle enables or disables ASR and ASI as discussed above, and is selectable per input port, not globally. "
I read this as saying if this option set to off, you don't have to worry about either of them messing with you.
As of last night when I switched back to the DVD player from the pc and found that it indeed had jacked up my locked setups, I went in to see how bad the convergence was (always worst on the left side) with the geometry jacked up as well It also seems that when this happens, the lines on the convergence grid look very "bloomy" and soft focus, and the blue started to twitch and jump when I went to try to clean up the convergence again.
Any ideas?

Never heard of this. Is there suitable substitution?

Hello
Not so. Adjusting locked recalls causes new adjustments to be lost. Trying to adjust a setup created in ASI will be lost also.

DeOxit can be found at radio Shack, do not look where all the other radio shack brand cleaners are, they hide it away so you end up buying the radio shack cleaners. Look where they keep all the PCB blank boards and Bread boards for electronics.
it should be there, if not ask but insist on the Caig DeOxit and Pro gold contact protectant comes with it,
Aslo pic up an IC chip puller if you dont have one allready to pull up the chips and clean the contacts. I use some Caig sparayed into a shot glass and dip the tip of the tooth brush and scrub the pins. make sure you remeber the orientation of each chip . Also clean the board with denatured alcohol and tooth brush after. Then last i ad the protectant to the pins and place them all back in.
Most of you have going on sounds like a software issue. I hope...

Can you run two video input boards on these? I was in the process of pulling the one out of the spare pj but it has cables attached to it, which leads me to believe only one of these can be in the projector. Is the connector on left side of the bord for add-ons like the Moome boards?

I've always given them their own setup and each has always had it's own recall memory saved and assigned in the channel list.
I've pulled the board. I don't have any of the cleaner right now and I'll have to clean myself up a bit before I venture out to radio shak. I gave each of the chips a press to be sure they are seated well. Nothing looks awry on that board. No signs of anything having been hot or burnt I gave it a good dusting with some q-tips All of the solders look intact as well.
