Power supply waveform

Hi
Attaching the power supply waveform. It is not clean. May I have any suggestions where to look into.
I have changed driver transistors.
Thank you.

Found the problem it was the driver transistors as they damaged the board too bad some pins which not suppose to touch had resistance on them due to carbon.
