Is a two leg diode in a zener looking package. The voltage across is -98v and -80v respectively. I took the part number from the service manual, but does not give me any more details. It could be a germanium diode. The pcb marking shows a regular diode. I am pulling my hair out. The dvom off...
After two weeks of pondering I think is a good idea to make an opening and install a case fan. Should I go with 120mm? blue leds? will it run all the time?
Replaced mbr1045 diode rectifier on heat sink. No luck. Power supply still runs hot. I mean hot as in I can only touch the heatsink with my finger for about 2seconds. There are so many parts (transformers, chokes, zener diodes, transistors, ic). I wish could identify to +12, +5 and -5 voltages...
I am out for shopping for a lcr meter. I have a hard time deciding between Agilent U1733C and B&K Precision 879B. Besides Agilent costing double does anybody owns any of the lcrs?
I have replaced a couple of blown electrolytics including the 2200uf one. Now the combo runs but with issues. For example, the power supply runs scorching hot. The hottest spot being the rectifier diode mbr on the heat sink, just behind the 2200uf electrolytic that bursted (not shown, already...
