Hello Friend. you have to check the + b filter. it may be dry, check the polyester counters that were in series with the tsh. disassemble the yoke and make sure that the vobinas inside do not have a short signal or are sulfated as a green signal, and check that the + b has a tendency. Do not be high, if all this I indicate is good it has to be the flayback that has an internal short. Also check the large source filter and rectifier diodes, also check the diodes and filters that are after the choper. Cheers

If the TSH is the direct equivalent of the original in its characteristics.
Possible causes of damage:
-Voltage of high + B.
- Tuning capacitors or leaking Damper diode.
- Damage or short circuit between turns in the YUGO in its horizontal section.
- High oscillation frequency.
- Flyback broken.
Attentive to these details.
