    Default Sony CTV KVHR36M31

    Hi all,

    Has anybody had anything to do with this model B4? We have one that intermittantly comes up with an error code on the front LED. It flashes 10 times. Service manual is coming but back-ordered. It weighs 90kg and the customer is, err, not very happy as its a recall. Funny how all the jobs owned by people like this become recalls or the parts go on backorder or whatever

    When you do things right, people won't be sure that you have done anything at all

    Hi there,

    Yes he is right, I had the same issue too. Ended up being the same IC. You can also purchase them from WES very cheap.

    Thanx fellas, 2 IC's on order, will just replace both and soak test for a year or two. Will let ya know what happens.........
    BTW, in the service manual where it says to clear error buffer, step 2 reads "press (8) then (12). That appears to be a misprint. There is no 12 button. I did it by trial and error and came up with (8) then (0). Good ol' Sony always manages a misprint or two in every manual.

    Yeah, I bet. Oh, by the way, the Sony appears to be fixed. I'm not going to say IS fixed 'cause then it will stop for sure, you know how sensitive Sony's are when you talk about them......

    As for recalls always being associated with certain types of customers, remember O'briens Law which states

    " Murphy was an optimist "
    Common sense isn't !!!

    I had one of my techs ask me if I had ever encountered a Sony KP-FW46M31 with this strange fault that set would not turn back on after warm up and shut down. Checked the unit over and found the same LED flash sequence as indicated in the early part of this thread. Turns out it has same IC's and Loc No's and same cure to boot!
    Thanks techs for posting this cure, it has inadvertently stop me asking for a cure on the forum just because I check posts every couple of days!
    You want to do what exactly with that screwdriver?

    I have one of these tvs..no faults yet but being a tech myself have always run it in eco mode. less beam current less problems. anyway ive heard that the caps on the powersuply need replacing once its 5-7 years old. still...good tv..compared to the plasmas from same era.
