Antique Sony KP-5000 Help - Page 2

Andy, thanks again. You are a wealth of information.
Your posts should be taped inside the KP-5000's for future generations!

I think I got a bit closer with the horizontal lines of the grid. The focus improved in the aligned areas, to the point of where it is really not an issue. I guess it will never have the sharpness of a smaller screen, but if you are far enough back it really doesn't matter.

Only the left part of the screen is slightly off. The horizontal lines are just a touch droopy. The vertical lines seem to pull slightly to the left. Is there an adjustment that just does the left half of the picture or should it fall into place when the vertical lines are properly converged?

Thanks Andy, for taking me in as an apprentice projector technician.

It is comforting to know that the grid will never be perfect. I think I have come pretty close, except now for a few red vertical lines on the left which I may leave alone, or experiment at leisure.
The picture is now pretty good and watchable.

There is a slight out of focus on the upper left which can be seen on ScreenShot17. I fear that this is a yoke adjustment that I am staying away from.

The black areas on bright adjacent scenes are bright themselves, not pitch black as I would expect. It is more of a "movie theater black". The black on dark scenes (on full black station breaks) are really black.
On a conventional set, I would think that a problem such as this could be addressed with the contrast/brightness controls, but on this one I think there is a bit more going on here.

As the Little Old Lady has not found her manual yet, I am stumped as to the function of the VIR. It's Hue and Color seem not to do anything. It doesn' t seem to be for preset color, as I would have guessed. There must be an easier way to adjust the color and hue than requiring the use of the Fantastic 4's Stretcheable Rubber Arms.
Didn't Sony at the time let the remote have a dual function of controlling color and hue.
If they did, the method of operation escapes me.

Part of the apparent curvature is I believe due to the angle the photo was taken, but yes there is a good deal of curvature in the image.

I kind of like it though. It brings back childhood memories of Expo '67 and the Bell Canada Pavilion's 360° Round Revolving Screen. Mounties on horseback coming at you from all directions! But I digress.....

When the lights are out, one could imagine looking at a view screen inside a Flying Saucer.
For the ultimate in round screens though, you just can't beat a Planetarium.

Your set sounds very interesting, but given the extra bulk, seems like it could suffer from a low wife approval rating!

Hello Brooklyn. Love your set up.

As grantautry's set came from an ABC affiliate auction, I can only guess that that the Dymo label tape warning was probably to discourage the office staff from using nail polish remover or other substances on the lenses and mirror.
The big mirror must be easily scratched, as when I got mine it had visible scratches. Not what you would expect from a standard hanging wall mirror for instance. The owner's manual (which I don't have) must explain cleaning procedures for the lens and mirror in the do's and don'ts section.

Windex is not a very efficient or recommended way of cleaning lenses.
There are very good articles on AVS forum for just such endeavors. As I am no expert on the matter, I will leave you to discover them.

That repair manual sounds mighty interesting. I have no documentation at all on it. The cheapskate that I am, I am just waiting patiently for one to float by in cyberspace.

In the interim, if you could explain the function of the VIR. It seems to do nothing. Is there a way of adjusting the color and hue by using the remote?
Maybe the volume and channel change have dual functions?
It is very difficult to adjust without making many trips back and forth to the set.

Always good to hear from another KP-5000 owner. By my recollection, there seem to be about a half dozen of us at least. Unfortunately, the working sets seem to be in the minority.

With so little information on the internet about this set, it amazes me that this thread keeps coming alive.

Anyone else out there?

The infra-red (at least it's not Ultrasonic!) remote commander (RM-601W) is VERY simplistic. Volume, Channel Change & Power are all that it contains. It appears to be programmed before Sony standardized their codes, as it does NOT control their later products. You may get lucky with one of those fancy one for alls, if you have the patience to go though all the codes. I imagine finding an original remote would be like finding another KP-5000!

Your picture looks great. The alignment also seems very good. Apart from andy2000's excellent alignment advice (earlier in the thread), I could not add anything further.
