Hello,
As a foreword I'm relatively novice with component level audio gear repair. My amplifier stopped producing sound and I currently have no funds to buy a new one so I need any help to repair it. I know "no sound" is one of the most common problem but there were other symptoms so some of you seasoned repairman might able to pinpoint the stuff I have to check. I did download the service manual from manualslib the "no sound checklist" is a bit intimidating.
So i bought it working. First symptom: speaker protection relays on the audio board were clicking...05-06-2024, 10:16 AM -
Hi
I have a Citronic AC-1USB.
When I run a turntable into it and then try to record it. The volume is too loud and distorting. In the red. Mainly 12” Singles. I haven’t tried a CD into it yet. I’m wondering if there is any way to bring the volume down inside the unit itself. Change a part or two. Put a small pot somewhere as there are no adjustments at all in there. I’m looking for the schematic but not found one yet.
Heres the circuit board inside.
Cheers

Hi all,
Looking for advice please, regarding those 2( film capacitor?? - honestly not too confident if are film capacitors). Short version of story : I bought a stagepass 500 active speakers, and found those components nearly blown. I know they are 1= L 125. Any advice where I could find them to buy, and also what else could lead to this fault?( I have a multimeter and soldering iron and I can get fixed if someone could give me some instructions)
Thanks all05-13-2024, 04:06 PM -
It's possibly a Chinese offbrand laptop that uses a generic series of motherboards called y116te. It has no image. All power rails are working. No bios dumps could be found on the internet. Tried similar bios from this [URL="https://www.badcaps.net/forum/troubleshooting-hardware-devices-and-electronics-theory/troubleshooting-laptops-tablets-and-mobile-devices/bios-requests-only/106647-thomson-neo14-bios-unlock#post1825903"]thread[/URL]. No difference. I wanna try cleaning the TXE region of the bios but cleaning TXE region seems too advanced for my skills. Please help clean the TXE region...Today, 02:39 AM

Hey guys, I have a Lenovo Ideapad 320-15ikb NM-B241 rev:1.0.
After turning it on, it runs for a few seconds then shuts off completely. No screen, no fan. After shutdown, a red light comes on and off fast. I've been trying to troubleshoot this for days now. It's never been opened up; the Lenovo sticker is still intact.
(!)I tried with a different BIOS battery, without any ribbon cables, on battery power, without the keyboard, and it's always the same.
Any insights on what might be causing this?...05-13-2024, 03:05 AM -
Hello,
I have a MacBook Air 13 inches 2014.
I have set a EFI password and I can't remember it : now I want to reinstall macOS and I can't because the MacBook is asking for the password.
I know how to remove the password with a usb programmer.
I plug the usb programmer to the motherboard and to my pc with usb, I read the EFI and I save it to a file.
Then I have to find this value in the file : $SVS because it indicate where is the password.
But I can't find the value.
I have attached the file

Hi All,
Thanks for reading. Based on the interesting fact that the vertical lines issue don't seem to effect the menus whatsoever but rather everything around the menu regardless of video is shown, I'm trying to set mine whether the issue is the main board or the t-con board.
Again what's baffling is that the menu is not effected whatsoever. However, any other video displayed regardless of inputs or when no inputs exist exhibits the vertical lines and seem to effect black areas only.
The lines are green in color when the tv is in "Game Mode" and...05-12-2024, 10:52 AM -
