Hameg HM1008 Scope
« on: November 08, 2018, 04:17:32 am »
Hi, I have got 4 units of Hameg HM1008 all with the same capacitor blown on the power supply. Has anyone else come across this problem?What could be the possible reason - all the units are maybe 6 years old. I haven't removed the pcb yet so don't know the function of the cap for sure but I'm assuming it used to filter out the main AC in.
Can you please help me to identify the make of this capacitor
Thanks in advance

Yep, exactly that.
They're one of the X or Y class of caps and not necessary for operation.
Replace with non-translucent case varieties.

The capacitor is in the line filter section  before the bridge rectifier, if i recall this capacitor can crack on the casing and fail ?
