My 420 is quiet.

The video shows that snackdragons' is clearly defective (though I'd remake iw with the audio turned down).

If JVC's are generally as reliable as I think they are, it seems penny-wise and pound-foolish not to take care of him.

If they can't observe it the next time they get it, I think a reasonable solution would be to give give him a refurb 420 in exchange for his unit, or if not available a refurb something else at a good price.

Thanks for the reply. The audio was not raised or lowered. That's straight from a google pixel phone mic.

I was referring to the loud, rather distracting music; the clicking would be much more noticeable w/o it.

Have you put your ear up to a JVC on start up? All of them that I have owned, before the current generation, make funny noises on start up. My 3000 is the first one that I have owned that is pretty quiet. I am not saying his 420 is in spec or not in spec, but I will say, I would not expect it to be quiet on startup. My 45, 57, 600 and 640 all made funny noises on startup. If you have a model not from the current generation, put your ear near a vent on startup and see if you do not hear funny noises. Now those noises should not be loud and the E-shift buzz should not be loud, but I definitely can hear the E-shift buzz during a movie at times. That is why I do not use E-shift on my 3000.

Well my 540 makes the woodpecker sound on startup when the DI initializes. I think that's normal, or at least mine has always done it. The sound his made in the video went on quite a bit longer than mine. I guess I don't know if the 420 is any different though.

OTOH, all the noise I could hear it making during playback despite the volume not being turned down on his receiver is not normal. Mine does this now that it is not working correctly. Dead quiet when it was new and it's within 3 feet from my head.

Can't say that I have.

My projector is a bit inaccessible, high in a closet and firing through a hole in the wall, so it also has noisy auxiliary cooling fans.

My RS-420 makes the DI startup noise, and has some e-shift noise, but no clicking during operations.

Yes, I was just referring to the startup video. That sounded pretty normal to me.

Lens Shift Issue?

I was hoping someone could help me out, I have an issue that's driving me insane. I have a JVC DLA-X570R that I got from BestBuy (I have some suspicions it was a refurb) and I've been using it pretty heavily for 2 years (it has about 2500 hours in eco mode).

I've had about 4 screens in that time, and I've fiddled around each time with lens shift to get the perfect image. However, I can't seem to get the image to line up with screen anymore (it's crazy off now, or results in bad keystoning), so I'm wondering if the lens shift is failing? From looking at the lens of the projector, I can move the image to the top-right, center, or bottom-right, but not the left. Lens shift still seems to work in all directions when I try to use it but I cannot get the image to line up anymore.

So, my newb question is, are there multiple motors at work in lens shift, where perhaps one has died and is now making my life hell. Or is the issue with my fiddling around with the projector and screen?

One other issue I notice is that when I hit “Center Lens” the image move towards the center and stops (eyeballing it, it doesn’t look dead center) and I get a message “adjusting, please wait” that doesn’t fade away. I can back out of the lens centering and that breaks lens shift, zoom and focus until I restart the projector.

Can anyone confirm with their unit if this behavior is normal?

Sounds totally abnormal, and you said yourself it wasn't always like that.

I’ve never tried the “center lens” function before, but yeah, combined with everything else it seems to suggest that something is up with the lens shift/motor.

Closing the loop here as I was able to fix my issue.

It seems that what the projector thought was centre has moved up and to the right over time, so it thought it couldn’t go to the bottom left. I went to the service menu and reset the lens centre by eyeballing what looked like dead centre based on the image coming out of the projector. And viola, the image can now go back to the bottom left and onto my screen once more. I might email JVC and see if I should expect this to happen again over time.

Thanks for the help.

Thanks @T-Bone ! I do enjoy the 420, and will for sometime. Another thing is darkening the room, I think that has made a huge difference to me anyway.

A few minutes later the projector shuts down and throws a code.

I have another thread going that outlines my back and forth with the various manufacturers. It was suggested that I hit this thread and look for a combination of button presses to factory reset the device. Nothing’s turning up with my searches and 2800 posts is a lot of reading!


Wanted to hop back on to simple say, great warranty and customer service at JVC. It took a while to source the part but they have replaced the processor board completely under warranty. Top notch service!

So first time really powering the projector up. It’s been a journey, I’ve now officially owned it for 2.5 years. A now have a very basic -don’t laugh - question.

The lens is roughly 15 feet from the screen. Screen is 155” 2.39 format. I assume with the lens shift that the projector will automatically detect the format. Then, I play a 16:9 source, fit to screen, save. Then play a 2.39 source, for to screen and save. If that simple assumption is correct, I run out of zoom in 2.39. There is still about an inch on either side of the screen that does not fill. Pretty sure at that throw it has enough zoom.

Appreciate the assistance.

According to the calculator at www.projectorcentral.com you would need a minimum distance of 16'8" to fill a 155" 2.39 screen.

I don't think the projector will automatically adjust based on source, you have to toggle between presets to use the zoom.

Doh, yup, absolutely right. I gained an extra 6” of throw pushing the projector to the back of the cabinet and I’m pretty close. I’m sure full zoom will hurt the picture somewhat but from what my eyes saw last night, not a big deal at all.

I do have another question regarding HDR. I’ve never experienced it on a projector before so really don’t known what to expect. I watched Terminator last night and 95% of the movie the picture was absolutely stunning. There was the odd scene however, where you could barely make out what was going on - super dark. I’m sure this will vary with the film and I’m only 1 in at this point. Just wondering if this is a normal thing? Also, I’m assuming a person wants to switch from the HDR profile when watching a non HDR film as well.

Thanks for the help.

What player or source were you using?

To get the best you need to use HTPC-MadVR, second best is Panasonic UB-420 or custom curves (which you have to first calibrate your projector). Also, assuming your projector hasn't been calibrated after the update, your gamma may be way off, hard to say.

Source is a Panasonic 820. Definitely going to have the projector calibrated but I just can’t wait!

Are there any “try these first” settings kicking around?

@Gouie , getting calibrated does make a difference. If you have a laptop, then as @Dominic Chan linked, there are some great curves to load. But yes, that movie does have some dark scenes, especially the train ride. Enjoy the projector, and the 820, as I have both. Feel free to use the slider to adjust as needed. I think this film might be about 1000 nits....so you may need to adjust. I could be wrong too as I am aging more every day....

I’m through 6 movies in two days now, really enjoying the combination. Thanks for the guidance and I’ll definitely be searching for a local calibrator.

Silly question number 3; slider?

The Panasonic UB820 has a Dynamic Range Adjustment slider that lets you adjust the overall brightness of HDR.

The JVC’s gamma Picture Tone also does that.

Original JVC lamp dropped 20% after 500 hours, haven't tried Dominic's new lamp yet. Was hoping for 10% drop or less. At least it's a lot better than the old JVC's where I would average around 30% to 40% after 500 hours, with the lamp sometimes failing shortly after.

This was running the PJ near sea-level in High Alt mode, though it is in a closet (albeit a very large one). It's winter though, so the room was cool. I only ran Lamp High for less than 1 hour total out of 500 hours, and was always in High Alt mode (high fan).

Not bad, but not quite what I was hoping for given some other users reports.

My original RS540 lamp is down about 20% in just over 700 hours, so not that far off. Table mounted in a basement room that is always cool.

Still struggling a bit, have a couple of questions.

I’ve run through a few recommended settings and things are looking really good but slightly washed out. Im looking for suggestion on settings to play with? I’ve moved the gamma correction to 2.6 and it seems much better just not sure if that’s the right setting to be changing for the wash out effect.

Regarding source and HDR vs Natural; I’m using an Apple TV 4K so regardless of whether the film is 1080 or 4K the projector is seeing it as 4K. Is that normal? Does this mean I use the HDR setting for everything coming from the Apple TV?

Pretty remedial questions I know

I wouldn’t just move the gamma correction unless you know what you need to correct. Check the output settings on your Apple TV, it’s probably set to 4K. Personally I run everything at 4K SDR from my Apple TV because it has good upscaling and I do not like the HDR picture of my 420 even after have it professionally calibrated with custom curves added.

Also you can get a calibration disk and play with that for help with contrast and stuff. If you have the funds I would have it calibrated, best thing I did for mine.
