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.
Here are links to some of the tools used in this video:
After replacing the battery in this iphone 5c, the phone kept rebooting itself without any apparent reason. By using a schematic and board view of the logic board I was able to find the fault and repair it.
In this video I am repairing an old 19 inch lcd monitor (Iiyama ProLite E481S) who isn’t powering up anymore. As usual with these lcd monitors, the fault is caused by capacitors on the power supply board.
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
In this episode I will be repairing my AVR ISP MKII programmer by replacing the on-board boost converter TPS61020 and I will also upgrade the 6 pin ISP programming cable to 1 m length.
