KRP-500a Calibration Help

Rotorsport · 06-06-2009, 5:48 PM

Hi,
I have just purchased an eye-one display LT and ran thru the greyscale calibration using HCFR only to find that the Blue is reading what I think is way too high.

The set is a Pioneer KRP-500a and is running in pure mode with all colours set at 0. This is my first attempt at doing this and I may be doing something wrong. I have read thru the greyscale for dummies guide and setup everything as per recommendation. The i1 is not new and I fear it may be way out of calibration.
Please see attachment and give me some feedback as to what the problem may be.

Many Thanks.

What colour temperature setting are you measuring?

This was taken measuring 100% white running in pure mode which correct me if I'm wrong should be D65.

Why should it be? Every set is different. Your source can also affect this measurement. Put it in USER col temp and adjust it to D65.

Gordon,
Thanks for your input. I’m new to all of this and appreciate the help. What I’m trying to work out , is the i1 faulty. Below is an extract from Phil Hinton’s review of the KRP-500 and based on this I was expecting the TV to be very close to D65 out of the box. I have tried two different sources and two test discs both of which gave similar results.
So just to recap I’m running the screen in pure mode with colour space 2 and gamma 2 and checking against the rec709 gamut. Am I still missing something here?

“Well the latest Pioneers have two colour space selections and in previous models [colour space 1] has been over saturated against the rec709 gamut and [colour space 2] under saturated. However it has changed slightly on the KRP-500A in Pure mode. Now in this selection [colour space 2] is exactly right when it comes to the rec709 gamut. So this is the only TV we have ever measured out of the box that has not only hit almost all the points for primary and secondary colours, but does so with an almost flat greyscale and temperature of almost bang on D65.”

Thanks.

What Phil measured is pretty irrelevant to your own as I have noted.

If you want to know whether the probe is broken you need a reference to compare it to or to send it to manufacturer for verification.

Well my suspicions were correct, the probe is faulty.

How did you find out?

I purchased a new one

Let us know how you get on with the new one, Im tempted to get one myself. Currently trying to calibrate my 428xd with a spyder 3 borrowed from work but Im not sure how accurate it is. i have read that they can be hit and miss and dont work so well with Kuro's.
