    There have been a number of threads about the performance of the Sony 32FQ86 when viewing RGB inputs. The complaint is of 'interference' and/or odd patterning which is only evident on RGB. I have been investigating this problem and I now know the cause and have a temporary fix.

    The problem arises because in RGB mode (either scart) Noise Reduction is turned off. This is not mirrored in the user menu where NR adjustments all appear as normal, they just don't do anything. Sonys NR circuitry is very good, it does its thing with minimal side effects and importantly one of its functions is to remove/reduce mpeg artifacts.

    I have been unable,to date, to discover whether the disabling of NR in RGB is deliberate or is one of Sonys not uncommon software cock-ups. It is however driven by the sets software (all versions). I have developed a means of activating NR for RGB and I'm looking for a handful of volunteers to trial it for me. I have been watching an fq86 with the NR turned back on and I have my own views on the visible changes, but I would like some more views as to whether I'm going down the right path.

    If you are familiar with the Service Menus and would like to help please post and I will pm you with the procedure. I would like to hear from you whether you find a problem with your RGB picture or not.

    Hi Howie,

    Have you had any luck with getting the fix permanent? I change far to frequently between s - video and teresterial channels to make it worthwhile setting on each time i want to watch an RGB feed.. i think it makes a difference.. but its hard to know if its not a sort of placebo effect.. from wanting the picture to improve...

    Cheers,
    Mick

    Mick,

    No luck making it permanent, the command seems to be written on the EEPROM, and I'm not messing with it.
    I think it does improve most pictures, but a particularly noisy picture can end up looking extra processed.

    Hi Howie,

    Do you think Sony would be able to fix this via a software update? If so would they be able to do it at people houses or would the set have to go back to service center? I wonder why its set to off in the first place!

    Cheers,
    Mick

    Howie, as you may have seen from my other thread on this page? I have just purchased this set and would be interested to know the procedure should I need it.

    My question would be - will I definately need it? Is this a fault throughout the range? I see that you have reviewed this set a while back. Any input in my other thread, from yourself, would be much appreciated as you are obviously clued up on this set and I am getting the feeling I may have ordered a poor set :(

    Not sure if this makes any difference, but all my tv viewing is done through Sky, not through the normal channels
