:help: Hi,this set will play tv or AV normal for few minutes and the video will disappear ,while the heaters are on and the eht normal and sound ok.all voltages are normal.I changed all eletrolitics caps on the B+ ,190v,12v,5v and 3v rails.This is an old set.now i suspect the x ray protection circuits ,but all seems well.But when no signal applied no aerial input the set dont loose video till it goes to standbye,telling that when much current is drawn (video or lopty current)is then that the fault happens.
