I can say without much doubt..........No. Sony has the market cornered for now. Their 4k stuff goes from
about 10K to 20K with very little discount available. JVC and Epson have in between models, priced from
maybe 4K to 10K but they are sort of hybrid being between our current standard and true 4k. I would like
to consider one of those but am undecided on that front. If I were a younger guy I would get the Sony
for now (I did !) and wait perhaps 1 to 2 yrs for a quality 4k under 5 thousand. My problem is time, I might
not be here long enough !!!! Home theater stuff is a moving target, I've never been able to catch it.

Hi Alan,

I didn't know you were a fellow Mits owner. I just checked in here today on a whim, but I still love my 92840. It will have to do for me until something reasonably affordable comes along in the 100" 4K/HDR range. That will be several years from now, I'm afraid, but unfortunately a projector and screen won't work in my room. And having been at this screen size, I know I can't go smaller.

Regards,
Mike

Hi Alan,

Without knowledge of your room, obviously can't dispute your reply. I am not an advocate for front projection, but it has
worked very well for me. I have a combo living/dining room with regular lighting (no dedicated area) and just placed the screen
against the wall behind where my 92 was. One thing for sure, the 92 gathers attention, but can be a bear to move. I carried the
Sony up the stairs myself (quite proud of that) and came away with a larger picture. One downside I neglected to mention is that
this particular projector has no sound....you must use your receiver for audio. Most probably do anyway, but you don't have the
option when you go this route.

Hey Mike! Great minds DO think alike.

Only a 73740 here...and now these guys got me thinking about projectors....again.

The Mitsu has served me well since 2011, but I am seriously considering the 75" Vizios....just want to wait and see what the pricing is on the M series before jumping on one of the P series.

I think I will end up going with a Vizio as well since the 4k projectors and OLED TVs are out of the price range that I'm interested in and the size I want. It will be hard enough going from my 92842 92" to a 75" Vizio.

Hi,

You said Sony, but if you carried a 92840 up a set of stairs by yourself (or anywhere at all for that matter), you have every right to be proud of that.

Mike

My mistake in word phrasing. It took 4 of us to carry the mits down the steps. I just
meant the Sony which is a much larger picture seemed silly in being able to basically carry
the thing single handed. The 92" is a classic for sure and never failed to turn heads with
"wow, that's a big television". Ironically the projector screen gets not much notice at all,
until its got a picture on it ! A big picture in any form is the way to watch things.

Hey, dumb question here... but what liquid are you guys using to clean your screens and/or projector lenses? Thinking it's time for a tune-up.

Put it in the classifieds. http://www.avsforum.com/forum/255-rear-projection/

I have a 73742 and was wondering how to tell if the screen needs to be cleaned. Due to the texture of the surface of the screen, I have a hard time telling if there is any dust on it.

If you've never cleaned it, I can guarantee you will see a BIG difference once you do.

Wait, are you talking about just the front of the screen?? That should be cleaned on a regular basis and is very easy to do...cleaning the interior of the screen and the mirror is a bit more complicated, but very worthwhile.

I'm assuming you have to remove the screen if you are going to clean the mirror and the inside of the screen? I've not done that, although I do have the service manual and see the instructions on how it's done. Did you have to re-do the geometry settings, etc. after re-installing the screen? I did all the geometry work back when I received the TV, taking most of the "bending" around the edges out. Any recommendations on what and how to clean, and maybe more importantly, what to stay away from?

Where in the manual are the instructions for that? I'm not seeing it.

The screen removal instructions are in the Service manual, not the operating manual that comes with the TV.

I have removed/reinstalled my screen multiple times and have never had to re-do my geometry settings.

It helps to have a second person when taking off the screen, but I have done it by myself multiple times without issue.

I know you should not use any window cleaners with ammonia. I just use the same glass cleaner I use for my eyeglasses and a microfiber cloth. If you are so inclined, there are products made especially for cleaning TV optics/mirrors...I've never found the need for anything that specific though.

It's not difficult...there are a dozen or so screws on the back of the TV (all marked with arrows) and two under "pop-off" covers on the front/bottom/center of the TV. Pull the bottom of the screen out from the TV first, then lift the the entire screen up to remove it. Reverse to re-install. If you have short arms, get someone to help you!

An electric screwdriver makes the process about 5 times faster.

Do NOT over tighten the screws when re-installing! They are easy to strip...ask me how I know.

alignment of picture 82740

Apologies for my lack of avsforum skills, but I can't find what I'm seeking and I'm sure it's here SOMEWHERE!

I have a 82740. I really like the TV for all these years it has served me well, I do not relish the cost of ever having to replace it. I have really only one annoyance, and that's the picture geometry. If I didn't know better I'd never notice, but since I used to install/repair 3-tube CRT projectors I can tell my 82740 needs some adjustment. When I bring up a video game from my PS4 that has uniform content around the edges, I can see my picture is not centered, the right is a bit "taller" than the left, and I have some pretty noticeable pincushioning on the right side.

So, long story short, is there some sort of service or alignment menu I can get in to adjust the projector geometry? I'm sure hoping this is not mechanical mis-alignment such as mirror and such. Any help appreciated!

You need to go into the Service Menu. WARNING! You can jack up your TV messing about in the Service Menu, so BE CAREFUL!

Hey, thanks for the pdf!!! I had been searching and searching here and could not find a service manual for my 82740. Found many links to older chassis' like V37 and such but none for our models.

For those seeking a manual, the xx740's are a V45+ chassis, the xx840's are a V45++. I only found the manual online though by doing a search for "service manual mitsu v46" and voila! The instructions in it are a bit different than what Augerhandle posted. It is too large for me to post here.

My TV is actually down right now as the lamp faded out on me during a PS4 gaming session yesterday but two new 915B455011 bulbs are arriving today.

Follow-up: Bulbs arrived this morning so my set is back up and running. So for the first time ever thanks to what I've found by checking here, I was able to go in and adjust all the geometry's and get rid of the keystone and pincushion that have slightly annoyed me for 5 years! Sheesh, all it took was a day of getting off my butt and remembering AVSFORUM was out here. THANKS ALL!!!

The instructions I posted were from the Technical Training Manual for the V45, V45+, V45++, V45C, V45CA, V45CB, and V46 (Laservue) chassis series. It's interesting that yours is different.

What I found was apparently incomplete, yours had more (the blue and red lines sections).
I wish there was a H and V size adjustment. The overscan is more than I'd like. Will have to fiddle with bringing in all 16 points, though I'd prefer to shrink it optically rather than digitally (losing pixels). Not a big deal though as I'm sure that would mess with the projector focus which I don't want to deal with, as it is it is SO much better than before, I love straight lines!
