Hello everyone.
I'm working on a friends computer. She doesn't have a lot of money
and she says she really needs it working. It was just shutting down randomly. It got to the point where it wouldn't stay on for more than a few minutes, if that. I decided to open it up and found six OST caps with bulging tops.
The OSTs are all rated the same, 1800μF, 6.3v. They have the markings RLZ O734 on them. I believe they have something to do with the voltage regulator circuit. There's a total of 9 of these 1800μF caps on the board. I was going to replace all 9 of them.
All read leaky with my ESR meter except one which is off to the side by itself. It's reading around 3070μF. Could this of caused all the other ones to go? I was thinking maybe the power supply caused the problem even though the power supply tested fine with my power supply tester.
Also, I'm not 100% sure what capacitor replacement I should go for. I read that the RubyCon MBZ series would be a good replacement but I couldn't find them for sale on BadCaps or on DigiKey. Any suggestions?
Thanks.
