Luckily, my old Chief mount could handle the larger JVC. It came with various mounting arms and i used the larger arms which fit the new JVC. Sadly, Chief no longer makes mounts...
Chief still makes mounts. In fact, I think they make the best mount out there.

I should have clarified... Chief no longer makes mounts that will fit the current JVC projectors. The one i have is a huge mount that was nearly the size of the projector. It is an aluminum frame that has slotted holes. You align the mounting holes in the projector to the slotted holes in the frame to fit...

If it's not a BIG screen, it's not a theater...

What you are saying is not correct. Chief makes mounts for the current JVC's. I think what you are trying to say is the Chief universal mount no longer fits the current line of JVC projectors. Hardly any universal mount fits the current line of JVC projectors. Though some people have extended the arms farther than manufacturer recommendations and or use extension pieces to make them fit. Instead, you should just buy the correct interface plate for your existing Chief mount.

This is correct, Chief has custom Mounting Plates for all the JVC Projectors. The only one requiring a new mount is the RS4500K because it is 85lbs ....

In reply to Hardvark's post regarding the RS1 that fell off the coffee table. I do happen to have a need for a parts chassis RS1. I've got an RS1 in our office that we're trying to stretch out that just had a power supply failure we think. I'll be happy to fund shipping if your parts unit is still available and powers up. Thanks, Mel

Question

I have an RS-1 with an RSVP with isf calibration.
I'm still super happy with the picture but the cooling is becoming more and more of an issue.
I have a thermal aux fan mounted over the top to supplement to cooling.

I've been through the forums trying to find fan replacements.
So far all I've come up with is either used fans or JVC asking for $425
110 QAR0449-001 DUCT FAN $83.79
59 QAR0447-001 LAMP FAN $144.
21 QAR0446-001 DUCT INTAKE FAN $122.
71 QAR0448-001 DUCT PS FAN $77.75 (Exhaust)

Has anyone been able to source any modern day equivalents?

The JVC RS-1 is now ten years old... At that age, manufacturers are no longer required to inventory parts for a product... You might just want to consider buying another projector, used or new that is more recent. You would not want to buy expensive parts for it now and find out shortly another issue arises and there is no parts for it...

If it's not a BIG screen, it's not a theater...

Whoa! Was hoping the forum had some enthusiastic “fans” of the RS series.

The RSVP with the ISF calibration unlocked and of course a bit’o TLC, still make this a wonderful projector.

Just hoping to swap out some fan’s.

I am not trying to discourage you but just stating some facts that you should consider... I have a RS-1 as well that has served me faithfully but I do notice that the colors are not as rich as before. My guess is that the D-ILA panels are fading over time.

If it breaks, I will not repair it... The RS-1 has almost no value now and the latest models are far superior to the RS-1 in every way, they are a lot brighter with better colors and the contrast is far deeper than the RS-1.

If it's not a BIG screen, it's not a theater...

Hey Thanks Jon,
I’d pull the lamp and examine for any grey spots on the mirror surface of the bulb.
This can turn colors drab.
Then clean the optical block, with a lens cleaning cloth.
I do this with a head mounted flashlight, to see any anomalies

Update on those inexpensive Osram bulbs from Bulbs America:

After 50 hours I had to bump the power setting to high on my RS1 to keep the brightness optimal.
After 100 hours, I'm now tweaking the picture settings; increasing the brightness and contrast to compensate for the bulb dimming. (And not so successfully, of course.)

I think it's clear now that these bulbs have a more rapid drop-off in brightness than the original JVC models. I still enjoy my RS1 after more than 10 years (has it really been that long?), but I think it's time to replace.

I have a spare, brand new, unused Osram bulb I might slip in. Why not enjoy the brightness if I can?

In the end, the lower price is nice, but I'm not going to keep buying them.

-Pete

Colors fade when the D-ILA panels age... The colors are no longer as vibrant as before...

Hey Jon,
Okay, although I spoke to an engineer at JVC last week about an install I ws doing and he mentioned that in his experience he's only seen the optical block yellow with age, but that's from smokers. ¯\_(ツ)_/¯ ॐ

Tired of seeing bogus dates shown on forum threads, I am adding the actual dates to my posts.
I replied on June 26, 2017:

Thanks Pete.

Last year I installed the BHL-5012U lamp intead the of BHL-5009.
It sucks that it's expensive but, It's the best lamp the RS1 has ever had.

I have a case of osram bulb's, among other's, and the issue is finding one that has no defects whatsoever.
That's why there is such eradict pricing on these bulbs.
The less expensive the lower grade, due to found defects.

The 5012 also has a metal case, so there's no off gassing of the plastic in the projector.

If some manufacture could come up with an LED replacment that would solve a whole host of issues's.

For those of you reading this thread in reverse order... Here's an update on my use of the Osram bulb from Bulbs America.
After 150 hours I saw a rather significant reduction in brightness. To watch the newest episode of Game Of Thrones, I decided to put my SECOND brand new Osram bulb from Bulbs America.
I was very disappointed! This second bulb seems to be only slightly brighter than the bulb with 150 hours on it.

Cosmuk's note about the bulb's quality is spot on. I'll look at the BHL-5012U; but it's probably time to think about life after an RS1.

I would be looking at the great closeout deals on the RS400. Big step up from the RS1.

The RS400 deals are pretty good now. About $600 less than the RS420.
Would you guys recommend spending an extra $600 to get the RS420? I know that's an impossible question!
