I have question about FW900 flyback transformer. It is as I understand it one of the most failing component on FW900, right?
can it be transplanted from other Trinitrom monitor model (21")?
is it possible to buy a dtp94 right now?
the DTP-94 has a reputation for maintaining stability over long periods of time. You can always measure the native primaries of your trinitron and see whether the chromaticities match up to what they're supposed to. However, if you are a professional calibrator, then yes, you need to periodically have your instruments certified.
My DTP-94 is years old and is as accurate as my brand new i1 pro. Many other users have commented on the remarkable stability of this particular instrument, and it has a well earned reputation. I'm not saying factory calibration is useless - I'm saying that it might not always be necessary depending on your needs, and that there are cheaper ways to see whether it has drifted.
...For the enthusiast and regular users, this may not be the case. You need to stop, think, ask and answer these questions: How much valuable is your monitor to you? How long would last if left uncalibrated and without proper maintenance? Is your monitor a integral and key piece of equipment in your workflow? Can it be replaced with something equally (not similarly) effective?...
H-K shorts can easily be diagnosed with the Sencore CR-70 and the CR-7000. If the unit has an H-K short, the tube is done as the short cannot be removed by the instruments.
I know there are many work arounds for fixing certain types of shorts, but working with the Trinitron tubes of the GDM and CPD line of computer monitors, we have never been successful in removing H-K or any shorts involving HV and/or the cathode/focus lead.
Make sure that ALL color calibrators, spectrophotometers, spetroradiometers you want to purchase are factory calibrated before you buy them.
If not, then the readings will be way off targets, and is money down the drain. Make sure that the company that manufacture them is still in business so the instruments can go back for service and be factory calibrated before they are used.
Hope this helps...
also, just got the following reply from a Sencore rep when asking about differences between the CR70 and CR7000 (other than that the CR7000 tests 3 guns simultaneously):
"There are few differences in the display on CR70 an analog meter is used with the CR7000 it has a sliding Good/bad scale. The CR70 requires the user to setup all of the parameters (K, G1, G2, F1,F2) where the CR7000 does not require that which makes setup and testing much quicker. Other than that they both perform the same function and you should receive the same end results with both."
Hey Vito. I know that landing is only supposed to be adjusted if you have any discolorations on the corners. But it looks like the landing adjusts the geometry on the corners for me as well. Does this possibly mean my screen is magnetized? Also - you have a PM.
Interesting, found this confidential Sony Bulletin on DAS and WinDAS.
It has a list of compatible signal generators. However, in WinDAS you can set the configuration to manual, and use a different signal generator.
One thing that struck me is that some of the compatible generators only have pixel clocks up to 250 Mhz. That doesn't seem fast enough for 1920x1200 @ 85 hz. Maybe WinDAS only requests 60hz at that resolution?
