Hey Austin Texas Buddies? Can anyone help me out?

mike_frontier · 01-24-2003, 01:15 AM

Well I finally made some final decisions on my theater system and equipment and now I need a big favor since I am not the knowledgeable about it and that’s doing an SPL test (correct). Can any of you guys here willing to help me out so I can get the best sound and setting calibrated properly? Also my RPTV might be off a little and I do not know anything about red push or how to set it. The instruction manual sucks. But if any of you guys can help me that would be great! Let me know?

Thanks

The 1st 2 pics is my current theater setup.

Take a look:

Mike, for your Mitsu RPTV red push issue, do a forum search in the display area - this forum, AVScience and Hometheaterspot forums - tons of info available.
Speakers: First, I'd build a shelf with a vertical brace or two on the back, extending downward to rest on the back of the TV (maybe rubber tips on the bottom of the braces), so you can place your center channel on top of the RPTV. You won't be happy with the center channel speaker to the side of the TV. White van speakers???? Are you one of those guys? "Studio Monitors"...mmm-mmm...where can I get some?!

I've got an analog RS SPL meter and an Exel file fill-in-the-blank form with extrapolated/extended frequency intervals you could use also.

Hank,

The Yamaha speakers is my setup as of now. Thats with the 2 towers on each side of the RPTV in the pics at that link

. The pic you are talking about is the Warlf Zaldek speakers I tested, that center is huge and was way heavy and did not trust it to be on top of my RPTV

.

Hahaha about them white van speakers,, yea I got suckerd about 4 years ago. I was on my way to Best Buy to buy an car cd player for my wife old honda accord and as I got out of her car a guy stopped behind me and showd me these speakers that said they were retail price of 1200.00 or some crap like that. I was not interested. Then all BS to the side and about 10 minutes wasted of my time. I decided to try to hear them at least so I had at the time a littl 100x2 Pionner car amp and lucky I was the speaker wires were long enough to come out of the truck so I plug the pair of White van speakers and they did not sound that bad. So I spent the money that I was suppose to buy my wife car cd player with on these speakers LMAO.
But there really not bad at all. In all honestly the 2 12" 3-ways rocked in stereo mode, nice treble. But oh about the price..I remeber getting them for 180.00 for the3 pair and at that time I don't even think best buy had floor speakers for less then 200.00 for a pair and espically 12" 3-ways

Mike,

In order to adjust the red push you will need to use the service menu, which of course your owner's manual will not tell you how to access. I used to know the code, but I haven't messed with a Mits in a long time. As Hank said though, it should be easy to find doing a keyword search of (Mitsubishi Service Menu Code) on any of the popular RPTV/calibration forums.

I should caution you though that unless you have a color analyzer, and/or have a lot of experience calibrating RPTVs, I would not jump into the service menu and start messing with the RGB push & drives. While it may look like you have a red push problem, it may in fact be a green drive issue. The only way to be sure is by measuring the color temp and analyzing each color output. Worst case scenario, always remember to write down the current settings, so that you can always get back to where you started.

Good luck, those Mits are not fun to calibrate...

I know of several ISFers who charge more for Mits sets because of their calibration issues. That said, the effort is almost always worth it for the improved PQ. While you are in there, you may also want to evaluate your convergence. In my experience Mits sets can only hold their convergence for about a year, so if its been that long since it was last calibrated or if its a new set, more than likely it could benefit from a little adjusting.

Good Grief! You're wife shoulda smacked you upside da head.

Hank,

She did slap me on the top but close to the back of the head,,, but still kinda hurt. She was pissed b/c she still had a honda tape deck and I had a set of 12"s that I really did not need. DOH!!

Nils,

My RPTV is a Samsung. By looking at the manual its not called red push, but it called Red Convergence and it can be set w/o getting into an service menu from my understanding, but maybe this Red Convergence is not the same as red push?

Jonathan DA · 01-24-2003, 03:42 PM

Red push and convergence are two very different issues. If your problem is convergence, you can mostly fix that via the standard menus without entering the service menus. Just enter the convergence section of your menu and use the arrow keys on your remote to adjust the crosshairs, boxes, dots, or whatever Samsung uses until everything lines up. That should get you started.

Nils Luehrmann · 01-24-2003, 04:30 PM

My mistake, I read Hank's response and he mentioned that you had a mitsu.

The best way to determine whether your problem is with convergence or with your gamma settings is to run those specific test patterns found on VE or AVIA. I have both if you would like to borrow one. If it is a convergence issue and your set allows for convergence calibration without going into the service menu then you should at least try and fix the problem that way. I would be very surprised however if that type of calibration is very thorough. Most sets I have encountered have offered no more than 10 points of convergence. I suspect that by going into the service menu of your set you will be able to fine tune the convergence with a 72 point grid pattern. Also, when you are doing convergence, it is a good idea to start from the center of the grid pattern and spiral out. Doing so will save you from having to go back and fourth between grid points as you make your adjustments.

If the problem is related to your gamma settings (which unfortunately is the case for almost all new and uncalibrated TVs), then I would recommend you hire an experienced calibrationist armed with a spectroradiometer, color analyzer, or optical comparator who then will be able to set the gamma correctly.

For future reference to any one considering RPTV, Toshiba's are the easiest to calibrate and maintain their calibrations the longest. Mitsubishi's are the worst in both respects (excellent PQ though once done). Sony's will hold their calibration well, but calibrating their gamma is complicated by the fact that each change in a drive or push results in a 100 degree or more difference. Compare that to Toshiba's which change only about 10 degrees. I have never worked on a Samsung, but I even in the case of Mitsu's and Sony's, its just a matter of practice and patience and eventually you can get it perfectly calibrated and have a superb picture.

Nils,

I have the Sound & Vision Tune-Up DvD and set the contrast, brightness, tint and color and looks good (I am sure avia is better). Also my RPTV has this options called Wizard auto focus, which sets up the focus automatically, but can I tell the difference? Not really. RPTV is new to me that why I need 2nd opinions and help if I am doing everything properly, I read the manual... but its not to much info on allot on what this RPTV has to offer in the setup menus,, so I just do not want to mess anything up ya know?

Hey guys maybe you can give me an opinion. I am seriously thinking now to return my RPTV for an Theater Projector. The price is about the same which is about 1600.00 and today I was at Frys and saw one that looked pretty good. But since I do not know nothing about them maybe you can assist me and let me know what the pros and cons owning an projector versus my RPTV.

The model I am looking at is made by CANON and the model# LV-S1. Now please forgive me since I once again have no knowledge about projects like you all have. But one main reason why I like projector is it takes up less space and I can always make the view size larger which is always great,,,,, oh and it can be portable

.

But here is the link the the canon specs. Let me know your thoughts on it?

Thanks guys

Nils Luehrmann · 02-01-2003, 12:25 AM

First of all, the LV-S1 is a data grade projector (300:1 contrast ratio is the most obvious way of telling). While it may do a decent job as a laptop presentation device, for video it will fall well short of projectors designed mainly for video.

There are some video grade projectors that can be had for about the same price. The one getting the most attention due to the positive reviews and rock bottom pricing is the InFocus X1 (MSRP $1,600; 1000 lumens; 2000:1 contrast ratio; 3000 lamp hours; and faroudja DCDi video processing chip set). Its only obvious weakness is resolution, but as long
