Mike - I am somewhat confused with above. The only thing resembling above I can find is in Utiiity:Preferences and then I can toggle Auto Power on to be either Off or ON
I changed mine from Off to On - is that what you meant to setup correctly for using direct AC off?
One of my goals is to not have to routinely use the Marquee remote - just to power the projector on and off using IR controlled outlet |
Yep, that's it!
Auto Power-up On/Off
If Auto Power-up is set to On, the projector automatically powers itself up
when line power is removed then re-applied. For example, if power is
temporarily interrupted due to a lightening storm, the projector will
automatically power itself back up when power returns. If Auto Power-up
were set to Off, the projector would require a manual power-on.
Note: Upon automan’c power-up, the most recent display adjusmmts may be
lost if they were not yet saved in the current setup memory

A sort of unrelated question that does relate to another post in this thread (see above standby comment (BTW to WTS - standby is a different state than what was being discussed which was power off but outlet powered (fans running and maybe battery being charged)
What is the purpose of Standby? I have like 18000 hours on my PJ and maybe 300 or so in standby. I never use standby. Is there some reason to sometimes go into standby ( I realize the tubes are energized in Standby so they are using tube life but I suppose they are not burning the phosphor while retaining a good setup since everything stays warm).
So is standby appropriate to use instead of power off if you are coming back to watch in say 1/2 hour - or would it still be better to power off and save tube life?

In "standby" the Marquee is basically in the video mute mode. Meaning all electronics is 100% active, with only the signal from the BNC's being disable from getting to the tubes.
When you turn the marquee "off" with the remote. most of the electronics turns off from the LVPS. And the filament volatge to the tubes drop somewhere between 3 and 4 volts. So in the off position, the tubes dim a bit from the decrease of filament voltage they get, and most of the voltage rails are disabled from the LVPS.
Your Marquee has been in the full on mode for 18000 hours. The reason you would find this is usually from two things happening:
1, it was used in a 24/7 operation or it was highly used--left on without a signal to it.
2, somehow they forgot to turn it off or put it in "standby" after each use.
The "standby hours are low in comparison. Not sure what was going on there, unless they did not always for get to use standby.
Don't get too hung up on saving the chassis and tubes by wanting to turn the set off when going to the bathroom or during dinner time. Just make sure you mute or disable the video and don't worry about anything else.
After all, It's a Marquee!

Yes - since I bought this several years ago from Clarence I have put maybe an additional 1000 hours at most on the PJ. As I mentioned I never used standby before - maybe I will start using it now but the tubes still appear to have no wear or maybe a 9! (They had to have been recently replaced before I got this or it was a babied PJ). So if they really are good for 5-10k hours looks like I will be suffering halos for the rest of my life? Probably better for me than getting glycol leaks and messing with a 9 incher!
The only other thing that bothers me about the fan and heat is that last summer I would get occasional loss of sync after several hours of operation. It has disappeared through the fall and winter - but if it comes back again during the summer I will have to maybe insulate the ceiling above PJ better and then leave the power on to outlet to cool things down to lessen the heat inside PJ

To the bold text in your quote... NO, dont use stanby for long periods !!!! Standby just mutes the video but keeps the tube heater filament on full, so you will burn out the tubes faster, not the phosphor the guns. Shut the PJ dwon or since you have seen no issue just pull the plug. Standby is for when you might have to stop the movie for a half hour or so to take care of something then you can come back with out waiting for the PJ to warm up.
the sync issue in the summer can be from the boards expanding more and loosing contact somewhere on the CLM(most likley) or another board due tot he extra heat and humidity. Cleaning all contacts of all boards may help. But it can be a cold solder joint somewhere on the CLM or DPB.

Careful here. I have several commercial installs that I'm running in standby, and that has been the case for years. And on a lot of installs that's what was required..
There's a reason why we keep them in standby... And no, you can do so without damaging the tubes. fact is, there's very little difference going on between 4 and 6 on the filaments. the tubes stay on either way... and so that you'll know, it takes a many hours of use to "burn out" the tubes that wa , and you're not likely to do so in standby period.
Much like the high end audio guys who leave their tubes sets on all the time. There's also a reason for that...

I always thought that keeping the PJ in standby was not a good idea, i am sure i have read posts of people who have
bought marquee's with mint tubes and no wear but they have extremely low emissions? then when they are asked for the hour count they say 1200 hours on and 10,000 in standby, and the response is there you go, the standby hours killed the heater's! What am i to believe now? I'd like to know for my own use as well.
And for the bold part i marked, yes this is to minimize the shock of a cold turn on, but on the marquee that is done by leaving it pluged in no? there is about 2.5-3.5 volts on the heaters and that is not enough to were out the guns, but at full 6.35 is another story or am i misinformed?

Athanasios,
I agree with Mike on this, standby is no issue.
The biggest problem is for the heater voltage to be above 6.35v, this is what kills the emission of the tubes.
As for the heat issues, The LVPS is no problem,
I would be more concerned with the hotter running HDM and FCM, they are the 2x hottest boards in a Marquee.
They are cooled by the belly fans, so for me, the LVPS is no problem at all.
Cheers
Steve

Well my loss of sync came back a couple weeks ago after it started getting hot again - after being gone all fall and winter
I was about to leave the CRT world and get a digital - PITA to be one hour into a movie and then lose sync. Happened again tonight watching a Blu Ray on PS3 so turned it off to come back tomorrow and then turned the lights on with wall switch dimmer; and noticed banding changing dramatically on the pj just by cycling the lights (with no video input) but Moome box with power.
So I began to wonder whether this could be external to pj - got and extension cord and plugged it into the bathroom's ground fault protected circuit and then directly powered the pj; and it worked fine for the rest of the movie.
So maybe its my IR remote controlled on/off switch or something similar in the power to the pj. I also noticed my lines in dark scenes really are affected by moving the extension cord.
So perhaps I will be able to figure this out after all and stay with my CRT.

Sounds Like the Dimmer switch. I would not put any Dimmer switched in. they can add EMI to the circuit. Some circuits in one the VIM can act as a radio reciever.
This could pic up interference from the Dimmer. Also dimmers add noise to the power lines . Also You should have all you sources and PJ on the same circuit to avoid ground loops, this is what you might have also.
Add an Isolation transformer to your system and you'll be very happy with the results.
I have a thread on this in the home theater construction forum.

Thanks
Could be the dimmer switch - but its a single wire on a push button that cycles three recessed lights by sensing the capacitance. The lights are normally off when watching so I think that's unlikely source during operation
Yes - I guess I have a number of potential problems that I will start looking into one at a time. The PJ ground loop is a pain as the PJ is powered off a circuit in the attic and it would be difficult to run power from the outlet where all the other equipment is powered. For now I will try an extension cord and get them on the same circuit and see if that addresses the wavy lines (pretty likely a ground loop or similar problem based on how the lines changed when I moved and twisted the extension cord last night).
On the loss of sync - I was hoping it was the remote power on/off IR device at the ceiling outlet. Reason being if its not that I am still not sure what is causing my infrequent but bothersome loss of sync (which is somehow also heat related but went away last night after powering off another circuit. I also used a separate power feed into pj since the one on ceiling goes from the front of pj to the back of pj to get to outlet and could be picking up interference. Then there are all the wires I ran in the same location up the wall from AV cabinet to the ceiling (including the vga to pj) - If I knew then what I know now I would have run the video separated from the others.

I would check that your belly fans are all running, possibly 1 has stopped.
This would cause the HDM to run even hotter than normal which could cause the loss of sync,
the 1 fan stopped also causes all the other boards to run hotter including the CLM and VIM.

I assume the belly fans are way up against the ceiling? If so they are not accessible to me. Due to the way I mounted PJ (threaded rod penetrating the ceiling and secured to angle irons attahed to trusses in the attic - my pj is permanently mounted. If it comes down it will probably stay down. I don't think there's a way for me to check filters if there are any either.
I realize this was not an optimal mounting - but its a fact for my install and limits what I will do to troubleshoot.

The HVPS side has the biggest hole to look through.
First you need to remove the large plastic side cover, 6 screws (1 is in the ACON connector plate)
You can take off the top side covers off, hopefully you have no screws installed on the top
Shine a torch through the hole to see if the fans are all running.
If a fan has stopped, then you will NOT have to take the projector down, just the tubes, HDM FCM and their sleeves,
this will get you to the belly fan tray section.
There are no filters in the Marquee
See how you go, post back to let us know.
Cheers
Steve

Steve and Athanasios -
Thanks for the response and advice. At this time it appears I am dealing with two separate problems (1. heat related but very infrequent loss of vertical sync, and 2. sets of interference lines that are only visible in fade to black scenes). And from my recent experience there is a possibility that the cause of both of these is external to the PJ. So I may try some external things before pursuing things inside pj.
I am going to try to enjoy and watch the PJ for a while - and if the loss of sync comes back (like it did last weekend and which went away when I changed power input) I will power pj from another circuit again with an extention cord (next time I may try the circuit my AV equipment is powered from to try to see if its possibly ground loop related) That action will get some potential problems out of the loop such as my IR controlled power switch at outlet and the ceiling lights powered via a dimmer and a set of OTA antenna preamps that are on that circuit.
If its just the dancing lines in FTB scenes I am beginning to suspect the ground loop plus a whole lot of induced interference from about 10 AV cables I have running right next to my VGA/bnc cable to pj. I think to troubleshoot that I will just get another cable and try it out in the open and see if my lines go away.

ground loop issues are a pain to diagnose. But OTA antennas and cable/Sat boxes whose cables are grounded on a different location usually are the fault.
I had to run a ground wire from my Sat distribution box, that was grounded right in the main electrical panel box. all teh way over to my av cabinet and ground it there. cleard up a Hum i had as well.
