I'm stumped. The on/off switch opens when off. I would expect that to shut off all power to the set. The heaters are lit when the set is off, but there is no HV. Wierd. I'm pretty sure those sets get the heater voltage from a winding on the flyback, so HV and heater should come and go together. Is it possible someone rewired the set to get heater voltage from someplace else? Even if so, the heater only burns a couple watts so I wouldn't expect any noticeable heat. Perhaps a leaky or shorted capacitor across the power switch? Nah. that doesn't explain the heater staying on but no HV. Charles mentioned the deguass coil staying on. That would hum, and make a mess out of the picture, but it would run warm, at least until something (thermistor?) dies. Try unhooking the deguassing coil and see what happens. RCA used to activate the coil when the TV went OFF, not ON, so a leaky thermistor might keep it going. I dont think I have ever seen that design on a Samsung, but there's a lot of stuff I have never seen. Still, all of this deguass talk doesn't explain the heater staying on.
I'm going to bed.
