Question about Sony KV-20S20 20" TV
Hi, I got an old Sony KV-20S20 TV. I replaced the transistores in the HOT area and a D1877 transistor on the cold are. I replaced a small 0.47 ohm resistor befor the two transistor on the hot are. The tv can turn on but after 5 sec it always turns off. Measured the current that was 80 mA. I unplugged the ANOD and still have the same issue. What can I do?
Thx in advance

There should be circuit designations printed on the PC board. Without those, there are too many possibilities to give you anything useful. Can you provide those please?
