Repair Oscilloscope PM3055 - Repair-Tutorial

This video is not about paranormal topics this time, but about a repair of my Philips PM3055 oscilloscope.
The oscilloscope could not be switched on after many years of use. Only a high pitched tone was audible and it did not turn on anymore.
Quickly the culprits were found. Since this oscilloscope was built more than 30 years ago (1986), the electrolytic capacitors of the power supply are therefore completely damaged.
In this video I show which capacitors are involved and after their replacement, everything worked properly again.
Below I have listed all the capacitors with their direct link at Mouser.com.
Good luck with the repair and....
Stay tuned :)

In diesem Video geht es diesmal nicht um paranormale Themen, sondern um die Reparatur meines Philips PM3055 Oszilloskops.
Das Oszilloskop liess sich nach vielen Jahren des Einsatzes nicht mehr einschalten. Es war nur noch ein hoher Ton zu hören und es funktionierte nicht mehr.
Schnell wurden die Ursachen gefunden. Da dieses Oszilloskop vor mehr als 30 Jahren (1986) gebaut wurde, sind die Elkos des Netzteils stark beschädigt.
In diesem Video zeige ich, um welche Kondensatoren es sich handelt und nach dem Austausch dieser, funktionierte alles wieder einwandfrei.
Weiter unten habe ich alle Kondensatoren mit ihrem direkten Link bei Mouser.com aufgelistet.
Viel Glück bei der Reparatur und....
Stay tuned :)

Hi, do you know how to turn on the XY mode on that scope?

[@transcommunication_switzerland]

Hi, since I no longer own this oscilloscope, I can't help you. But here you can find the complete manual www.qsl.net/vk5bar/AHARS-Resources/Philips%20PM3055/Philips%20PM3055%20Operating%20Manual.pdf

Maybe i have found something:
To enable the XY mode on the Philips PM3055 oscilloscope, follow these general steps:
Power On: Make sure the oscilloscope is powered on and properly connected to the input signal.
Select Channel Input: Choose the channels you want to use for the X and Y axes. Typically, the X-axis signal comes from the horizontal deflection input, and the Y-axis signal comes from the vertical deflection input.
Vertical Signal Setup: Adjust the vertical sensitivity and position knobs for the Y-axis input channel to properly display the signal on the Y-axis. This will control the amplitude and vertical position of the signal.
Horizontal Signal Setup: Adjust the horizontal sensitivity and position knobs for the X-axis input channel to properly display the signal on the X-axis. This will control the timebase and horizontal position of the signal.
Select XY Mode: Look for a mode selector or a button that switches the oscilloscope from normal display mode to XY mode. This button might be labeled "XY," "X-Y," or "X-Y Display." Press this button to enable the XY mode.
Adjust Display: Once in XY mode, the oscilloscope should display the X and Y input signals as a waveform on the screen. The X-axis signal will control the horizontal position of the waveform, and the Y-axis signal will control the vertical position.

@@transcommunication_switzerland Thank you, i will try it, i think the manual says it's "X DEFL". I wonder why they didn't just do section about XY mode
