 there is a noise comes from the transformer for a few seconds when its switched on at first then no noise for about an hour.
Thanks Alan.

mac18:
Hi again just run this set with the back cover off and over a period of two and a half hours no noise at all
put the cover back on and after ten minutes the noise is back again.

tv tony:
try spacing the two inductors apart at the top of the panel, we have known this to cause ringing as well, in severe cases we have had to put one on the print side of the pcb, well crack it,
tony

mac18:
Hi again tried separating the two inductors and its just the same cover on noise with in the hour and cover off no noise at all beginning to think along the lines of the transformer getting to hot or just faulty.
