The manual can be found here: The X amplifier is at page 47, but I have a screenshot of the schematic attached. I then looked further into the schematic, realizing the X amplifier is more complex than I thought it would be, and I am clueless what to check next. I did the usual things, checking voltages and obviously dead components, but all looks normal. With the problem persisting even in the component tester mode, I am very confident that the problem has to be in the final X amplifier. I attached a picture of the scope, the X-Pos knob was in the center position, and the trace should have covered the whole screen. The same happens when putting it into 10x mag, the trace gets cut off on the right side. When put in X-Y mode the dot can't be moved to the right as well, and when moving the trace with the X-Pos completely to the right, it only covers like 2/3rds of the right side of the screen. The right half of the screen behaves like it is compressed to half the size. To the left it's drawn like normal, and when moving the X-Pos knob it behaves like expected. After being on for like 10 Minutes it suddenly stopped drawing the trace properly. Hello everybody, my Hameg HM 205-2 Oscilloscope has a problem with it's horizontal deflection. ![]()
