Re: rubycon shelf life
Higher Voltage rating is OK as long as it will fit the unit. They do not provide shelf life spec in the spec sheet.

Re: rubycon shelf life
If they're authentic BXA then no problem using them.
If they're eBay fakes, toss them in the trash.Comment

do capacitors have a limited life even if just kept in a box in storage? -
This is my first attempt at troubleshooting a board like this, I know I could just buy a new board but I'm curious to figure out how this works. I've been testing different components in the evenings this week and I think the problem is with the IC failing to start up for some reason. When the board is plugged in there is no standby voltage.
Then today it randomly sprung to life like a zombie but shortly died thereafter. I have no idea why it would have done that and its the first time I've seen it running. I discharged capacitors on the board last night, then it was sitting today.... -
Hi.
I have a laptop Dell Vostro 3501 which did not POST. When connected to power supply and turn it on, the keyboard backlight would turn on but nothing else. Sometimes there was 1 BEEP code indicating problems with BIOS.
Then I disassembled it to read the BIOS chips. It had 2 - 64mbit and 128mbit. I connected CH341A (with 3.3v mod) to both of the chips (still soldered on main board) and read them.
After I reassembled laptop back and tried to turn it on. Now there is no sign of life. Not even keyboard backlight.
Then I took the motherboard out... -
I picked this one up today.
Previous owner says no signs of life.
TV looks immaculate and its a 2022 model year so I thought maybe the one connect cable was damaged.
Got it home and put it on the Kill-A-Watt power meter and it was completely dead.
The TV model is QN65LS03BAFXZA - version: CB06
The One Connect Box BN44-01066D / BN96-54788Q / BN39-02470A.
I immediately remembered EazyBone's Samsung The Frame TV no power....One Connect thread and am preparing myself to tear the One Connect open and hunt for dead parts.
Will keep you all... -
Hello,
First of all im glad i've found this forum and i'm happy to start learning new things and sharing my knowledge with others!
Long story short : I have a laptop from work that has no power and no signs of life. My first question is: A 90W charger(19V 4.5A) is enough for this laptop? Because the original charger was 19V 6,4A(120W), so all the testing was done with the 90W charger because i don't have a 120W charger.
This being said, i opened up the laptop and i've inspected the MB and the components, everything seems fine, no sings of explosion, burn,...
