    hi,

    i have a second hand tv that produces sounds only after maybe more or
    less 1 hour. Picture was fine but the only prob is that sounds does not
    come on instantly.I tapped the tv chassis but nothing change. i checked
    the speaker but it's working. Any suggestions regarding this problem.

    Sorry, i did'nt specify the model coz I forgot to list it while leaving
    home.


    thanks in adv.

    sounds like a dry joint ,
    and only when the set has warmed up the
    joint expands and then makes electrical contact

    try looking around the audio stages , or if you don't know where that is
    try all over to find a dull or cracked joint
    you may need a good strong light , and a mag glass
    also wiggle component to see an movement on the soldered side
    if this can be seen
    then suspect that ..

    cheers
     
  4. Perhaps the video circuits haven't put their clocks back and the video
    arrives an hour ahead!
