Well I just got my RS1 mounted to the ceiling and everything else hooked up. I started playing my XBOX for about twenty minutes and all of a sudden the projector just shuts off COMPLETELY!!! No flashing red light, no cooling fan, nothing. The standby light wasn't even on. I checked the sleep mode and it was set to OFF so I knew that wasn't the problem. So after about ten minutes of thumbing through the manual, all by itself the standby light comes back on. Is there something wrong with my projector? I have it running through a brand new power conditioner too, so there shouldn't be any power issues.

Hummm... I'm certainly no expert on the RS1, but your projector's behavior is obviously bad for its health and, as most people are probably thinking, isn't something JVC would want the projector doing. To me, the interesting part of your post was the "new power conditioner". You may want to plug a floor lamp or something into it to ensure it's up to snuff because your symptoms sounds like either a bad power supply on the projector or a bad power source.

Of course, this is a total guess on my part. Best of luck!

That sounds suspiciously like the problem Rob Tomlin had (http://www.avsforum.com/avs-vb/showthread.php?p=10692992&&#post10692992) with his RS-1.

Is the power cord plugged in good to the back of the projector?

how come I'm not hearing anyone talk about plugging in their projectors to battery backups?, although this might not have made any difference in your case, but all projectors should be placed on some sort of backup power source in case of a powerfailure or brownout, hot shutdowns can end or significantly shorten a bulbs life real quick and there are battery backups with line conditioners built in, APC is one of the companies that make one.

I think most people have their pj's ceiling mounted, making it difficult to connect to a battery back up.

I just tried skipping the power conditioner and just plugging the PJ directly into the wall and it happened again. Should I try the high altittude mode? It must be heat related.

Where are you located? if you are way above sea level you may try the "high" altitude mode.

The only causes of a shutdown like described should come from the filter being clogged, air intake being blocked, stop timer activating, or an external power problem (not the RS-1). If these are not the reasons and it happens again, you should contact JVC support.

Unlikely but possible...replace the mains cable to the unit. If it still shuts down it sounds like the JVC is faulty. Modern switchmode power supplies are pretty robust. I wouldn't bother with the power conditioner.

There is a "hide" button on the remote control, if you accidentally pressed it you will think your unit is dead, press that "hide" button again & voilla! That should do it. It happened to me too.

I've had the same problem with 2 different RS1s in the same installation. When tested off site, they work fine, but in this one case it shuts down completely, like you pulled out the power cord. I have installed at least 5 of thes in other systems, and have had no problems. The old Sony D50 and a loaner JVC work fine in this installation. The shutdown occurs whether there is a signal present or not, any ideas?

I've heard of this RS1 shutdown problem happening to several folks now, but I've yet to hear what the root cause is with the questionable PJ's.

Call your dealer ....

It has come to our attention that using mounting bolts that protrude further than 30mm into the case can interfere/deform some of the internal ducting and cause overheating/shutdown of the projector.

If you are experiencing what seems like a heat related shutdown after 20-30 minutes, check the length of your mounting bolts. I would use bolts that will tighten within 5 or 6 turns from thread engagement.

Cheers,

I agree, your dealer should be able to exchange it for you under warranty if Tom's suggestion does not fix the problem.

I can confirm that the complete shutdown after 20-30 minutes is caused by the screws in some universal ceiling mounts. I replaced the screws with shorter ones, and the projector now has run for about 4 hours without any problems. As a bonus, that also eliminated a pretty bad ground loop problem I was having.

Glad to hear the problem is apparently solved...

BTW, there is a note about mounting screw length in the owners manual...not that any of you would ever bother to read it... :-)

Cheers,

Interesting. Not at all like my first RS1 issue. In fact, I am paranoid about long mounting bolts. On every PJ I have ever had I always take a toothpick or other narrow, soft probe (with the PJ unplugged, of course) and check the depth of the bolt holes before I use any bolts. In my case, the Chief mount fits great (including bolt length).

So far (after about 7 hours) my second RS1 is doing fine....

As for altitude, I am just over 900 meters (about 975). Since the room is normally quite cool and I never use high power bulb, Jason did not think I needed to use high altitude mode...

Are the bolts that come with the Chief RPA-184 the right ones, or are they oversized?

Thanks,

Patrick

Though I am not 100% sure...I know that the Chief RPA-184 was custom fit to the RS1 (including the bolts). I also know that I have sold many, many, many, many Chief's with the RS1's and not a problem with any of them (related to the mount that is).

That seems to be the case - mine fit fine with the bolts included - and I checked legnth before hand.

I removed the screws that were part of the rubber feet that ship on the projector, and used those screws in attaching the projector to a universal ceiling mount, but did not measure the legnth of the screws. I had the "mystery shut off problem" with my first projector almost right away, and it was replaced by the dealer. The second unit has been working fine for weeks, again using the screws from the factory feet, but I just had the first mystery shutoff with it the other night, which has me know wondering about the screws. Can anyone tell me how long the oem screws are so that I don't have to take the projector off the ceiling to check? Does anyone have a source for "safe" size screws so I can eliminate the issue? Thanks.

I mounted my HD1 on a Chief rpm184 about a week ago. No shut down problems yet. I used a long toothpick to check the depth of the mounting holes and only one was short enough to worry about. Unfortunately, I don't remember which one was short. In any case they were all deep enough for the 1" screws supplied with the rpm184 kit.

The screws in the rubber feet are about 1-3/8", and might be too long for that one shallow hole. It's hard to imagine that 3/8" could do that much harm, but maybe so.
