Hello from Finland.

I have Philips TV 29PT8702 chassis: MD2.12E which whines a lot.
It has also odd phenomenon which looks like ringing or ghost.
Few vertical bars on the left and the right part of picture.

I have varnished the L.O.T. and linearity coiletc. but no help
at all. The whining comes (I'm quite sure) from L.O.T. I took
few pictures if you like to take a look of the phenomenon.

I now took a stethoscope and removed the chest piece and listeded
with the tube and the whining is NOT comiming from the L.O.T but
from the power transformer. The sound circulates so nasty that it
is impossible to locate the whining using only my ears.

So there must be sometkihg. I measured the ripples once but must
do it once again. Any ideas (modifications)?
