Wat zal ik zeggen, geen goede combinatie. Ik heb ook een behoorlijk aantal Bose 100V audiosysteem panelen voor deze klant gerepareerd. Een eenvoudig ding maar het gaf een flink probleem. Niet zo vreemd nadat ik het relais en de connector … Lees verder

This is the connector from a 1700 euro cable (Merlin Gerlin / Schneider) Just plastic and cat5 cable, a fine example of very bad engineering. The 3 “hooks” broke because the construction is very weak. After some fun time with … Lees verder
This scope is a bit confused. Is it a Fluke or a Philips, or both. Philips on the front, Fluke on the top of the cabinet. Not much wrong with it. It had starting problems, the PSU wined and there … Lees verder
Because I get more and more secutest for repair, I experimented with several fixtures. Secutests are a pain to work on because there is no room and there are dangerous voltages inside. There is a PCB with big relais: This … Lees verder
These burned things began their lives as resistors. The problem is the pcb is fried too. First step, make pictures and a sketch and then I mill away the burned section. Then I make an insert and glue that in. … Lees verder
Tĥis is the pcb from a G&M Secutest. It was not working like it should. The problem turned out to be some vaporized traces inside the 4 layer pcb, a LM358 with ventholes, a dead 555 from the boost … Lees verder
A peltier powered dryblock from Isotech that stopped working. There was no current flowing to the TECs (peltier elements). That can be caused by a dead controller, dead PSU or dead TECs. They should have a very low resistance so that … Lees verder
This one had a few fried resistors due to a short caused by damaged isolation from a wire. I first removed the resistors. The picture above is after cleaning with IPA. The pads are loose but not damaged. The black … Lees verder
Fluke uses a resistor divider to tell the processor in what position the switch is. It is made from a sort of carbon film. At the picture above you can see it. This meter has also a problem … Lees verder
This tester is made unchanged for many many years. It can deliver 5kV and do 100mA. This unit was as dead as an instrument can be. The biggest problem was the power supply transformer that was dead. it has several … Lees verder
