A few weeks ago I had trouble with my dishwasher (Model: Elektra Bregenz GIF 3003 X). The problem was, that the dishwasher suddenly switched itself off during the washing program.
During the last RepairCafe I got a Marantz PM7200 amplifier in my hands that had a very interesting fault.
Whenever the output signal reached a certain level, the amplifier switched the outputs off (as I learned later on, that is called the protection mode). This symptom could be provoked by either increasing the input level or increasing the amplification by turning the volume control. The effect occurred on the left and right channel. It didn’t matter if I put a signal at both or only at one channel. Also the source of the signal didn’t matter.
Recently I scored a broken Fluke 233 on ebay. On the pictures it seems that the meter was in good shape. Only the display seems to be broken.
After some years the batteries inside the Olympus high voltage flash pack die. Olympus does not offer replacement Batteries. You have to throw away the whole battery pack and get a new one (which is about 200 €).
I thought that – before throwing it away – I give it a go and try to replace the batteries myself.
