Re: television goes again by hitting the top of it?

I will look into safety measures before working on the inside of the tv and
i certainly will not try working on it with the power turned on.

Thanks but I want to give it a go myself, for 2 reasons, the cost of
servicing compared to buying a new similar tv and I am reasonably handy
myself with although limited electronic knowledge. I know there can be
dangerous voltages left in the capacitors after turn off so I presume if I
short the power plug phase and neutral pins to the earth pin I will
discharge any voltage in the caps. The fact that it responds to a tap on
the top of the tv makes me think it is probably not in the circuit board,
it has settled down at the moment but the next time it goes haywire I will
trying tapping different parts of the tv and see if i can narrow things
down a little there before opening it up. Is it possible for dust to cause
this sort of problem or are there no conductive parts exposed to the dust?

Probably a bad solder connection on the circuit board, or a component
that
is going mechanically intermittent. Take the set to a service centre, and
get it properly fixed.

Hi there, I have a 12 year old sony tv that just suddenly started having
problems, first sign of trouble was that when you turned it on no picture
would come up, that includes osd, and then after about 10 seconds it
would
automatically shut down to standby mode again, no matter how many times I
tried it just kept doing this until that is I gave the top of the tv a
whack
at which point all was fine again for sometime but then most of the
picture
would disappear and there would just be flickering strips of picture near
the top of the screen and then if I did not give it some more whacks it
would turn off again. Any ideas as to what this could be, could it be as
simple as dust or is this the last dying gasps of the cathode ray tube,
why
would a whack help the tube to go again?
