tv sound comes after 1 hour

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.

All of the above is required if you are to expect any kind of pertinent

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

 

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

 

Sounds like you're watching too much porn...
