Same problem here and, as far as I can say, only on PGM/PST. The fader has already been replaced, the problem remains the same.

The situation just get worse! The staus holds even when I am doing sth else, like moving the Box Mask / Effect Send!!! The EIC guesses that might be a network problem! Any other suggestions??

Yes, all lever arms were calibrated many times when we were trying to fix this problem. I don't think it's a phasing issue either. I still think it's a lever arm position update problem. GVG never solved this, nor were they ever really interested in solving it other than the usual reset this and that, drain NV ram, reinstall the latest version, etc. Few if any clients were reporting this error which probably led them to believe it was a plant problem. Everything was removed from the network that didn't need to be there until the Kalypso had it's own network, then LAN wiring was replaced and double replaced including routers, hubs and switches as GVG was leaning towards a network traffic problem. Basically, anything not inside a box labeled GVG was swapped out at least once to no avail. Good times.

It had never happen when using the auto trans or the keyer mix buttons. Does it mean that it should not be the phasing thing? The EIC said he has calibrated the faders a couple of time. And the GVG guys has actually come to change on of the fader. But it just doesn't improve....... um.......

have you tried calibrating the M/E levers, that is something you can do yourself. you hold down all five? keys in M/E2 in the transition module (ALT/SHIFT/KEY SPLIT/?/?) for a couple seconds until the panel menu comes up.

I've been seeing this problem with one particular switcher for a long time, probably v4 or so. It doesn't happen with the auto trans, it's only with the fader arm as if the lever position stops updating somewhere midway through a transition and then it starts again, usually with the arm near the end. I've seen it on PGM/PST and ME3 for sure, but I don't use the other lever arms enough to know. This switcher was a very early version, the one with the external CD ROM and the nice hard buttons that should never have been removed on the menu panel. I don't work there anymore as of last year, so I don't know if they still have this problem.

I hate to ask this but did anyone check timing before the new facility went on-line? Sounds like H phase may be off on some source(s), that's why it happens. Does this "burp" happen when going to or from a certain source? Does it happen when you use the auto trans button, try a longer duration? Are you going through any analog to digital or d to a converters? Any SDI to HD or HD to SDi converters? There should not be any memory, except if you are in SECAM, in line. If timing is good you could try draining the NVRAM and clear the box and then remap the switcher and before building an E-Mem see if the problem still happens.
