Hello friend still in the fight with the Oscilloscope, I made some progress but I still can't fix the problem.

Good afternoon friend I don't understand anything about oscilloscope maintenance anymore in these three areas I have already checked almost everything and found nothing abnormal and now I am completely lost, in the power supply I found two electrolytic capacitors of 4.7x160 completely dry the C1532 / 1533 I changed it with the hope that it had solved the problem more and I don't know what to do anymore.
