Let's see, if this TDA6107JF is properly fed (180 / 200V), then its overheating is caused by a deterioration of this same IC or a "short" towards GND (earth or mass) of any of the cathodes of the Kinescope (TRC). There's no more! If that "short" disappears when the TDA6107JF is removed from the circuit, then to solve it you will have to replace this ADD ... with a new part. Greetings! Joansoler.

Hello fellow apparently if I have a short in gnd that is making me reheat the tda 6107jf and some resistance what I see is that the welding point is generating a spark I solved it but still thank you very much

Hi guys I have a short between the Gnd pin and the Rk in the middle of these two points I generate a spark voltages in BK 110V - RK 30V - GK 110V the The voltage loss is really generated by that arc between the two pins but I don't know how to correct this problem, someone can help me thank you very much partners
