Hi guys
In my spare time to upskill myself I buy joblots if stuff to fix , or attempt fixing and get some experience
I have a r460 that I wanted to fix and give to my nephew
As shown there is a burned ferrite bead, next to a high/ low side VRM pair on the back side of the card
I'm gonna try replacing these pair of VRMs. I wondered how hard they are to remove
I have a decent sequire solder iron and hot air, though may need to get a hot plate.. Seems these VRMs have big contact plates and could be welded

So I purchased a faulty GPU on ebay Palit RTX 3060 .. It had a broken fan ( it did not spin at all )
Long story short , is the PWM control of the Card seems to be intermittantly faulty
Long story
I replaced said fan , seemed to work for a while , until randomly the fan starts spinning at 100% ( around 3.2K RPM ) for no rational reason ( temps and performance are ok ) . Now fan spins , though several times a day the fan decides to run at 100% for several minuites a time .. Then resumes normal operating ..
bear in Mind the card can be cooled sufficiently...04-28-2024, 02:30 PM -

I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.04-27-2024, 10:55 AM

I recently purchased a used MSI GS66 with password locked bios.
If I'm understanding correctly, I can fix this by re-flashing the bios. Except I need a copy of the original bios because the updates don't have complete information.
Maybe I need to download my existing image and copy information (something something DMI) from there to the newest BIOS update downloaded from MSI?
Or maybe I'm supposed to request for the original, if any has it unlocked can they send it to me?
I'm tried following different threads here, but its confusing because MSI...Today, 06:58 AM -

TV: JVC LT-43C888 (purchased in 2018). This is a smart TV with Netflix, Youtube, Freeview and other applications via 'Viewd' app store
Problem with TV:
- Netflix stopped working so i tried to do factory reset from the TV menu.
- I confirmed on-screen but the factory reset did not happen even. It did not take me to 'first-time installation' screen as mentioned in the manual.
- After waiting for some time, the TV went into a boot loop.
- JVC logo comes on the screen and LED light flashes for some seconds, then it reboots again and the same thing happens

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
