If the 2 transistors of the high voltage oscillator are working very hot, the most likely fault is a defective high voltage transformer. To troubleshoot this kind of problems, the ideal is to have another osciloscope of the same type as donor for spare parts. The first thing I would do is to replace this HV transformer by another known as good working and look if this solve the problem. |

Hello; problem solved. The fault was the capacitor C1061 (33nF / 63V) which was leaking. After replacement, the traces are fine and sharp. Cdt ;) |
