I have a power supply I'm trying to fix. I've narrowed it down to 2 bad transistors. They are marked ALG and BKD. They are smd sot23 package. Does anyone know what these are or how I can Identify them? Thank You!

Re: Identifying Transistors for Power Supply
ALG - LM4040BEX3-2.1-T
BKD - AME8570AEETBF31Z
maybe
but they arent transistors - so you may be looking at them wrongly -

Is having the schematic the only way to know for sure?Comment

Power Supplies should be boring: No loud noises, no bright flashes, and no bad smells.

Re: Identifying Transistors for Power Supply
What I gave you is the 100% ... Read the "Marking code" in the datasheet , and so in any datasheet of the BDK ..
Hard luck stj ;

Re: Identifying Transistors for Power Supply
nice try but you could read the datasheets of the part numbers i gave too.
truth is a lot of codes are used more than once.
my databook shows some codes relate to as many as 10 or more devices.
it's a total shitshowComment

Re: Identifying Transistors for Power Supply
why dont you just get yourself a book of smd markings?
i have a thread on the forum with a torrent for one.Comment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
Hello Everybody,
Trying to repair a power supply from a Russound CA4 Multizone Controller (picture attached)
Russound no longer supports it but were kind enough to provide a schematic of the power supply (pdf attached).
The outputs marked 12v and 20v are all measuring only 1v.
The board is clicking, which I think means it is in something called hiccup mode when the flyback transformers switches because of an internal problem or something else on the board Overloading it.
The capacitors physically look clean (no bludgesor leaks) and... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem...
