    I have a 10 years old 48'' sony kpef48me2 RPTV.
    last year (after 9 years of working perfactly fine) the tv started to
    loose focus.
    Most of the times the TV is out of focus, but focus seems to change
    all the time. Somtimes the TV goes back into focus for no apperent
    reason and can stay that way for hours (or go back out of focus in

    Does anyone know what can cause this problem, and wether or not i can
    fix it myself? (and if not, how much should it cost and does it worth
    the investment or am i better of throwing that TV away?).
