i have repaired several lcd tvs now and this is the first one i have seen do this.
when you plug it in the light (yellow maybe? green?) comes on for a
second and then off, while this is happening there is a very high pitch
squeal coming from the back that seems to increase in pitch, then when
the light goes dark the sound goes away.
and then it starts all over again and continues until you unplug it.
i have cracked the case on it and looked through the power and
control board . i only see one issue on the power supply, the large
450v 150pf cap is just barely extended, have not discharged the cap yet
to see if it holds charge or not.
need help on this one, it is for a friend who is way down on their luck and really needs some good fortune
thanks in advance
