In this video I am repairing a power supply board from a Samsung TV. The part number for the power supply board is MK32P5T (BN44-00213A). The TV was showing the stand-by led but refused to turn on. It turns out this was a common problem with a simple fix.

Voltlog #34 – Fluke 77 Teardown & Repair, Varistor Replacement

In this video I’m opening the Fluke 77 I scored at a recent auction to show and repair a small issue it has. One of the MOV (metal oxide varistor) in the input protection circuit had suffered damage probably while protecting the rest of the circuit when a HV signal was applied to it’s input, so I decided to replace the MOV.

The original MOV part number is V910LSX1399 specs: 910V 10% 1mA
The replacement MOV part number is Panasonic ERZV10D911 specs 910V 1mA
