thanks Jana
Tried that.
i actually just redid all the solder joints in the area and anywhere near
the area. tried flexing the board. the thing is that this unit failed while
in an entertainement center and never moved.....
Probing it hot now... carefully....
i notice that there is no voltage on either side of the power on softswtich.
that would make it dificult for it to have any affect i'm thinking.
There is a smlal transistor on the hotside of the switching transformer. I'm
wondering if that is what must be turned on?. without a schematic i'm just
stabbing in the dark. can i hot wire the turn on ckt?

There is probably a cold solder connection, and when the board is sitting
in
the cabinet, it is being stressed in the fashion to have the cold
connection
not making contact. Pull the board out, and jig run it. Then you can put
pressure on and off the board in various areas to aggravate the fault.

i have this Z27A11S zenith tv. It will not turn on. i opened it and
changed
a few caps that appeared good to me.
put the board back in and it turned on. great! ah, no. once i put the
board
in and buttoned up the back of the set it would not turn on again.
hmmm
put the thing away for a while.
back to it today. opened it up and changed a couple more caps. and voila,
it
turned on. I turned it off. and turned it back on a few times. looks good.
put the back back on the set and it would not turn on again!. what gives?
pulled it appart and soldered a bunch of connections thinking its a
cracked
trace perhaps. now i cannot get it to turn on at all.

where is the turn on signal? this is perplexing. it is so close to working
i
am reluctant to give up and chuck it.
Can anybody offer some help or advice?
thanks
