Hi,

I have a problem with an Hitachi model 27AX1BC. When TV is plugged, a high
hiss comes from
T901. I have changed STRD6602 (IC901) with no change. There is no voltage on
relay coil RL901 resulting
in no click. Also, IC901 comes very warm.

Does anyone know what the problem is?

Thanks in advance,

Marcel Noël
