55-60 degrees C on the heatsink, if memory serves. Maybe a Peletier
cooler is in order for them. :-)

Hi,

I have a Samsung TV TXE2545 mfg 4/97 in my shop with
half a picture (bottom half) which is linear (normal). At the center (top
of
half of picture) is a bright horizontal line. Above, the screen is black.
I scoped the input signal (pin 1) to IC301 TDA8350Q and it looks normal.
Pins 4 and 8 have a little above normal voltage. Could the cause
of this problem be IC301?

Thanks in advance, Brad

Vertical IC, but there is an upgrade for those sets also. They
(Samsung) recommend adding some components to the vertical section
(zeners and ceramic capacitors, I think) to stabilize the circuit.
Someone may have that information available.

They run as hot as a firebrand, or at least did when I worked on
them.
