Cracked solder joint on the common mode filter choke pin. I also upgraded the caps to PANASONIC FM series and re-soldered a bunch of solder joints.

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... -
Hello,
I have a DJ mixer here, an Xone:92 by Allen & Heath.
When I turned it on, only magic smoke came out, so I turned it off again.
An optical troubleshooting has brought me quite fast to the
source of the smoke: two resistors look disproportionately black (see first pic)
Those are R73 and R74 on the master PCB. See second pic for the corresponding page of the service manual.
Behind those resistors are five OP-Amps (U3, U4, U5, U6 and U9).
My thought is that one (or more) of those is defective. I've measured... -
Hi all,
Wondering if anyone here can help – I have an Allen and Heath Xone:92 silver mixer with one faulty channel – channel 2 is only outputting on one side (right side) when set to a phono input. It works fine with a line input, and all the other channels work perfectly with phono and line inputs. I'm not sure when this happened as I rarely use the faulty channel – it could well have been like this for years! Any thoughts on what might be causing the fault and how it could be repaired? I can do some basic soldering, so I'm hoping I might be able to fix it myself.

Hello Badcaps!
I am trying to troubleshoot my Allen & Heath Xone:02 DJ mixer. I have had this for somewhere close to 20 years and have played music through it in one form or another pretty much every single day since I've had it, though these days it's usually from a wireless streaming receptacle (Apple Airport) more than the turntables that are also connected to it.
This week my music stopped working, and after a bit of a wild goose chase, I realised my mixer was dead. I checked the 500mA fuse in the device beside the power supply and found it was blown, so I replaced...
