    I blew up my safety fuse (is that what it's called in English?) two times by trying to connect the tv-out of my laptop to the front s-video connection of my JVC HV32P40B.
    The consequence was that the geometry on my AV channels was messed up and that the colours on the component channel too. After finding (googling) out how to get in the Service Menu I fixed geometry (I have none experience in this, so it was trial and error). Now what rests are the colours on the component video channel. For your info, my Nintendo Wii, Sony PS2 and dvd-player are connected via component, so I'm sure the problem lies in the tv. I tried switching the values for colour and all but got nowhere near how it should be.
    Did something blew up and needs it to be fixed?
    Or is it a matter of filling in the right values?

    Perhaps someone has a list for me with (standard) values that should give a good coloured picture???

    Sorry! But you do need a TV Engineer to have a look at your TV.
    Due to you blowing the safety fuse twice.

    Sounds like the EPROM has corrupted and quite possibly blown another component?

    First need to set or replace the EPROM.
    The colours?
    If Grey scale is required it is not that simple.
    R-G-B Cut off and Gain settings are required.
    Just replace the EEPROM it should come pre-programmed from a JVC spares Agent.

    Good Luck!

    Thanks for the reply.
    I'm still waiting for JVC Service Centre to call me back. They're gonna tell me if they're going to pick it up or try to fix it at my place (I hope the latter).
    We'll wait and see!

    I'd also be very interested in a standard colour list on the JVC Service menu.. The picture on the 32WFT1EK i bought looks very very green. any ideas about how to correct this would be very much appreciated!

    Yeah, a service guy visited me 2 days ago, but couldn't fix it. It's kinda logic, since the SCART av channels as well as the tv channels were good. Since changing the colour values in the service menu would apply for the tv overall, the good channels would get bad then.
    So they have to come pick it up and investigate at their place :(

    Da Burridge,

    Don't write off your TV just yet. My first check would be your Scart lead and socket. Give them a good wiggle to see if the colour returns. I have come across 2 sets recently with the same symptoms that have been fixed by new lead or socket.
