Don't dump your CRT RPTV! - Page 342

Very limited need. I use mine for upconversion of 480i regular DVD material inside my Bluray player only. For all else I use component.

If your set has never been calibrated nor the optics cleaned - which is different from the coolant being changed, tho they might have been cleaned at the same time - then you're in for a huge surprise on how good it can actually look. Calibration always improves pix on CRT, usually making sets look better than new out of box.

Check out some of the screenshots in this thread. Start with page 260 and just keep checking them out, keep scrolling till you find the next set. Your set has the capacity for greatness too.

Overly blue no matter what is typically a grayscale issue, which any good ISF calibration would take care of.

If convergence crosshairs or grids are not lining up properly in one area or another, you gotta suspect one of those ICs is bad. True anytime the response to your convergence commands is followed only in a patchwork fashion, with some sections of the picture not responding. That's always been a bad IC.

We used to re-shoot guns when they were aging and weak, which brought them back fresh and strong. You would have seen a major difference in overall picture light level, esp. on your whites. But sometimes, just once in a great while, there would be damage done internally to the guns we shot, so we never shot them unless absolutely necessary. When necessary the improvements were dazzling, but the occasional mishap inside the gun resulting from that shooting was just not worth the risk.

Could be if you're seeing more blue than you should in the whites, that the blue was highly improved and red and green were not. If any of the 3 were not kept in step with the others, a new grayscale op would be necessitated, tho it most likely would have been necessitated anyway, just from the aging of the phosphors. All colors of phosphor do not age at the same rate. Which is why CRT tech - any tech that uses phosphors, including plasma - needs a grayscale op redone every few years.

The grayscale can be handled by any certified ISF agent, the better the reputation the better the quality of the work done. The rest of the work - about 70% of the total work done in my calibrations, the grayscale is only about 1/3 of the work done in mine - has to be handled by someone heavily experienced triple gun CRT tech, whether it's front projection or rear projection.

DK where the ICs come from in a kit like that - would not want you to be putting in factory seconds, which is what a lot of the inexpensive ones are, like from Electronix. When you pay labor for the replacement of parts or even when you do it yourself, the time/expense of that labor part of it dwarfs any minor parts price differences. So go for the gusto and get first class/top flight Sanyo ICs, like from MCM, Union Electronics or East Coast.

A grayscale op is dialing in the correct color of gray in your b/w images. Like the original Casablanca, in black and white. Which means .312/.329 co-ordinates on the Minolta Chromaticity chart.

Only when your grayscale on your strictly b/w images is the correct color of gray can you have absolute black where you should, and only then can you have the correct colors in your color scenes, once the color decoding is dialed in correctly.

I've got just what you need, tho you may live too far away. My 65" Panny CRT does 720p without even blinking. Last CRT RPTV made to do that, to have both 1080i and 720p native, neither converted or changed in any way. I have heard it can play 3D too, in 720p.

It's fully cleaned, calibrated, overscan reduced, color corrected and ready to go. Would solve all your problems other than the typical HDMI issue, which can be easily solved with an HD Fury.

b

Yes, buy a II or get a I from me. The Fury series is what you want for ending up at your set in component or RGB/VGA.

Whatever you do, don't hit the Default register! You'll trigger a self-destruct of all the factory calibration data.

When I got my service manual on one [b]of those Philips machines, that same advice was HAND written on it: Don't hit Default!

I am available for phone coaching if you want some guidance.

Maybe that's because people who paid lots of $ for both the 9" guns and their incredible size - their own private Imax - have decided that offing them in the nearest landfill would be an insult to their decision to buy them in the first place because they are such awesome sets, and are keeping them till they drop?

(hope so!)

Yes, I've heard the Mit DVI port is magnificent, and they really lost it when they designed their mulchy HDMI port later, like the one on mine that I will never use.
