I just replaced this chip and did the usual soldering of bad
connections on this 14 year old Sony.
Although the set now looks great the regulator IC runs too hot to
touch. The set has been operating for a couple of hours now but both
the chip as well as the heat sink are too hot it seems. I ESR'd the
caps in the power supply and they all look OK. Maybe hot is OK for this
circuit but I just thought I'd ask if anyone might have any thoughts on
this. Thanks. Lenny Stein, Barlen Electronics.
