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...Today, 12:07 PM -

I've got a lenovo thinkpad E495 that originally wasn't turning on and was acting like a bios issue. The battery was charging when the charger was plugged in and the laptop would act like it was starting and get stuck at a black screen with the backlight turned on. I tried reflashing the bios with a file I found on another thread on here when I searched for E495 bios ( I included the bios file below as well as the original bios I read from the chip). When I replaced the bios chip I got the lenovo logo screen to show up and was able to start the self test diagnostics and everything except the mouse...Today, 03:42 PM

Hi there! (I hope i'm doing the right way to ask this)
I'm working on a Dell INSPIRON 15 7559, with service tag CZ4X2J2.
Im sending both BIOS and EC .bin file and ask if someone can Clear ME it for me.
I guess it's only BIOS to be cleared, but I'm sending both.
It's taking too long to show the DELL logo.
I took this files from another original Dell motherboard which stopped working.
Best regards!
Thank you in advance!...Today, 09:36 AM -
Hello, I am back again, sorry for disappearing!
I was working on an Asus motherboard which might have a bad PCH.
So I had this Graphics card which seems to be showing something on the screen but it's full of artifacts, and I decided to make a new thread because I was in a wrong path!
I reballed the A0 channel, and then removed both A0 and D1 vram chips and the card is still showing the same artifacts with only a bit of change on the corrupt lanes.
I am starting to suspect the core.
I tried tserver memfa test but it gives me an error :[B] [error][Framework]...Today, 02:54 PM -
Hi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all...04-18-2024, 01:15 PM

Hi All
Been a while since I have been here, and a bit rusty.
I have the above laptop motherboard that was working and now the charging circuit is faulty.
Have 19v in fine until it hits PU4403 - not shorts I can see and thermal cam reveals nothing.
I have swapped out the ISL9538 and also the two mosfets (PU4403 and PU4405). Have 2.8v at the power switch, which pulls low when pressed - charging light comes on and goes straight off
Below are measurements (pin names are per the datasheet for the ISL95338 (couldn't find one for ISL9538,...Yesterday, 03:25 AM -
Hello Guys,
I am not familiar at all with plasma tv's but i tried my luck anyway since business is so bad. We gotta try, right?
Anyway, the original problem was a tv clicking and not starting due to a short circuit on the Z-Sustain board (on the right side from the rear).
I found two transistors shorted (30F123) and changed the gate driver ic's as well. I think they were FAN73711. I soldered for dry joint on power supply, Y-Sustain and Z-sustain. Started up the TV and the short was gone so i had an image but.....
Lots of colorful speckles on the image and also there...Today, 11:01 AM -
