    A client brought me in to try to “rescue” his picture quality. Starting with this comment I can already tell that the hairs are standing up on the back of Michael’s neck. The client wanted help and didn’t have unrealistic expectations of a calibration thanks to endless pitching on my part. His problem was a very grainy picture and washed out color.
    Starting by turning off all of the auto functions my thoughts were that this may correct the grainy picture due to the dynamic contrast. No luck. So I commence calibration and find the largest issue. At IRE 60-100 greyscale colors were spot on. Below that everything goes haywire. For cuts you only have adjustments for red and green and at that only 15 steps. Blue is through the roof with green low but red much below that. Could not gain any ground on error below 60 IRE.

    Philips with the results of this calibration and some good argument by the customer has chosen to replace this display. My question is did I miss something? Was there anything that I may have been able to do to bring this closer even with the tiny amount of adjustment that this set offers or was it just a defective display?

    Question is … was there a SM where there might have been greater levels of adjustment range?

    Lots of sets are like that … minimal range in the user side and macro range in the SM.

    I have not seen a Philips set in a long time …last one was a CRT set I recall.

    Sometimes on the low end … you might adjust it and let the dE readings be your guide. Get it to as low as it can get and double check it with your eyes.

    Regards

    Michael,
    That adjustment was from the service menu. Client is thrilled with the picture as long as the image is bright and cheery. This LCD set doesn’t even have a backlight control. Here’s hoping he does well with the replacement lottery. Philips is going to send him the first 52″ they get. No matter what model it is. I don’t suppose I could get Greg to accept this as one of my 10 calibrations. LOL

    As long as the explanations are there … you did your best and to the best the TV is capable.

    It should be acceptable.

    Send it in.
