TV power problem, relay clicks, only turns on when you hit it
 

I have a Toshiba 27" made in 92.

There is a bit of a problem with turning it on. Turning off is always
fine. The remote doesn't turn it on, but I hear a relay click. Also,
doesn't turn on with the front switch under normal pushing...but also
hear a relay click.
The only way it turns on, is but hitting the front "ON" switch really
hard, to move or jiggle the set, or the hit the ON switch followed by
hitting the set in a certain sequence.

I believe it may be the relay, or some kind of mechanical part or
connection because you seem to need to hit the set to turn it on. Would
like some opinions before I pursue this farther. I'm not a TV repair
expert by the way.

Anyone have any suggestions... anyone know what the relay looks like?

No kidding. :-)

It sounds like the set may have a dry joint. I suggest you reflow all
suspect solder joints before you make the problem worse.

... anyone know what the relay looks like?

It is usually rectangular with 4 pins. It may have a transparent case
through which you would see the coil and contacts.

you will need to resolder the power supply and high voltage components
where heating and cooling cycles have led to the solder becoing
cracked. if in doubt, have a tech do this simple and hopefully
inexpensive work, or you could end up trashing the set.

A wild guess.... to be sure!

Less wild than the two previous posters call for COLD SOLDER JOINTS !, I
would even bet a case of beer on it. We could get the O/P to umpire the
call.

I traced the Relay on another TV with the same symptoms same way, was
surprised by how small it was. These contacts are supposed to last a
hundred thousand cycles !
