    What physically occurs during an ISF calibration that could void the warranty ? Is there any "physical evidence" left behind from the tweaking that leads a subsequent repair tech to determine a set's been calibrated ?

    Thanks

    It depends on what you want done.
    Physical evidence ...
    Duvetyne glued all over
    Lens Hood ...
    SVM disconnected ... can be explained away.
    Lens Striping ... can be removed and redone if needed.
    Too well converged ...
    Too Little Overscan ...
    Both are also signs of tampering ...
    Looks too good ... [​IMG]
    Many things can be explained away as something the dealer provided ... and dealers do provide some of these services too.
    Regards

    Hi there,

    * cup imprints on the screen
    * IR receiver relocated
    * interior repainted (black)
    * washers under lens mounts (Scheimpfluge)

    Most techs unless calibrators themselves won't notice though... unless of course you volunteer it.

    Thanks,
    Errol

    Thanks guys - I thought it was because you had a habit of leaving Corona bottle caps strewn about the interior, or perhaps writing smilie faces on the "Warrany void if seal is broken" labels...

    Will an ISF Cal have a dramatic effect on standard NTSC viewing ? I'm considering a Mits RPTV, but am hesitant due to comments on the inferior line doubler. Since cable is the dominant viewing in my household for now, this is a concern.

    Thanks !

    Answer ... it depends on how bad your set is OOTB. Nobody can answer that for you over the phone.

    We have to be able to see the condition of your TV to make any kind of blanket statement like that.

    It is like asking us for directions to NYC, except that you cannot tell us where you are starting from. Jersey or Japan ...

    However ... !! While we can never promise anything, in most cases, the client has been able to see some measure of improvement in their cable / satellite. Garbage in, garbage out.

    Regards

    Thanks Michael- it was a pretty dopey inquiry.... Next time I'll try to be a little more vague [​IMG] But hey, the only stupid question is the one you don't ask !!!
    Thanks for everyone's help ! If I can ever feel comfortable with this DVI debate, I'll actually purchase a d-mn RPTV and leave everyone alone !

    Sounds fairly scary to me. What does this service run ( a range ) ?

    I had my Mits 46807 ISF'd by Gregg Loewen back in February and cannot recommend it (or Gregg) enough. He did an outstanding job and my Mits picture looks absolutely gorgeous.
    If I needed any repair work done it would be very easy to change a few things back and no repair man would be the wiser.
