Hello,
I have DSO5102 fpr ,pre than a year and the scope was working great until recently.
All of the sudden, the vertical and horizontal position do not work anymore.
I see the signal but can not move up or down nor can I move it left or right.
Also, Volts/Div and Sec/Div doesn;t work, do not change scale.
I tried to upgrade a firmware to the latest, didn;t help.
Let me know what could be an issue and how to fix it.
Thank you,

The keyboard should be fault. Please contact your seller to replace a new keyboard.
Calibration sometimes passed somtimes gives different error nubers.
My problem
No signal connected - both lines (channels) move up or down.
Most often movement is from middle to upper or lower possition out of screen and back.
Time for this movment up or down is in miliseconds.
Lines sustain in upper or lower possition for less then second and go back.
Repetition time of error is from few secconds up to 30 minutes.
When signal is connected - DSO measures fine but the same interruption as
was described without signal.
It is not suitable for serious work.
Could you guess what should cause this error ?
thank you Karol

In my humble opinion, it's very hard to find a reputable and trustworthy online casino. The only casino I can recommend is Ice Casino bonus code casino because people trust it. There you can find the biggest number of various games from table games to slot https://icecasino.eu.com/no-deposit-bonus/ games.
