by caspianDear members,
I have a linear variable power supply with unknown brand name that I used for voltage injection.
Then it failed. I discovered that its transistors (Q1 and Q2) are shorted.
In addition, I discovered that its zener diodes are defective.
I can replace the burned transistors.
But I do not know the model of the zener diodes. the model number is not marked on the zener diodes.
Therefore, I cannot replace the zener diodes.
I do not want to test the zener diodes in a test circuit to discover their model or value.
no schematics are available... -
by hobostoveHey there guys. I've got a Corsair power supply that's come across my bench dead. I usually don't mess with power supplies, but it's a slow week so I'm giving it a whirl.
Taking it apart I heard a screw rattling around inside, and when I got it apart I found a couple blown components near what I think is the 5VSB area.
There's a 22ohm resistor that's melted and open, but it still has the bands.
The other part is a zener diode and it's top went to jesus, so I can't read the marking.
It looks like the diode connects the source and drain of a TNY284... -
by nev1001Hi, I'm looking for a bit of help trying to fix the audio unit from a Maestro Mayhem 4.1 gaming chair please.
The chair has a few speakers and vibration motors. All was well, for a while, but now the sound is gone.
It may be significant that I discovered my son was powering it with a 19V laptop charger when it should run on 12V - it did fully work, for bit.
I think an issue could be a zener diode (or capacitor) which has shorted out.
The board's bluetooth input still works, the vibration motors are working, so is the line out socket but not the...-

by sam_sam_samI have bought this Zener Diode for this project what size and wattage resistor value do I need to use to get near 50 watt output
I bought this from an eBay seller but unfortunately they only had one
I bought three from Vetco Electronics these are Sylvania ECG5185A 9.1@10w A to Stud what size and watt resistor do I need to use to get near 10 watt output
I bought three of from them to also make battery packs with this output power limit in mind
I want to use this battery pack and turn it into a 9.1 output battery pack output to eliminate using 9 volt battery... -
Hi,
Finally replaced all of the shorted 4148's and resistors and an blown tl431 on my FSP300-60GTF after 5VSB going crazy and destroying it self. Those components also made the secondary transistors appear shorted (while in reality they weren't).
Powered it on through my dim bulb tester and they (bulbs) only flash once meaning primary caps are getting charged, but that's it. No 5VSB, PS_ON voltages.
I am sure I have replaced the components correctly and that there weren't any shorted/blown traces left.
Any ideas where to go next? - Loading...
