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!

do you have ASI on or off, Also I would lock each recall. Leave asi or ari off, Some times they can screw things up.

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

[Nashou66]

What happens if you remove the KVM and put the PC into the transcoder and leave out the sat box and switch between the two sources? the same thing?

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?

okey dokey.

Away we go....... I guess I'll crawl up out of the basement sometime tomorrow......

Thanks!

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.

Headed off to bed its 1 am here !

[loribates]

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...

[loribates]

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

[loribates]

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?

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?
