Figured its a dead gpu so I did a reflow with some chipquik and yep it came back to life for a few minuets and then when i restarted it the board booted up to a bunch of multi colored flickering squares. Into the...

    Crest CP500HT vs CP500D

    Ok so the CP500D is on backorder at the moment. My question is the degassing and the digital gauges that important or make it that much better? What settings do you use to clean the boards?

    820-332 green light no power Q8930

    No Title This is what the area looks like once I removed it. All 6 pads have continuity. PPBUS_G3H short still present. I can see the exposed copper for PPVIN_S5_HS_GPU_ISNS might be touching the exposed copper circuit for pad 1 and 2 on Q8930. The PPVIN_S5_HS_GPU_ISNS copper seems pretty loose...

    hot air station

    I have a FR810 and the digital adjustment drives me fucking crazy. I wish they made the same machine with manual knobs. Or at least make a different digital control panel thats quicker to use.

    Hello, I have a 820-3332 with liquid damage. I have never worked on one of these boards before. The only thing I can see visually is Q8930 which isn't looking too good nor is plane around it. I see what look like many little vias next to it which have lifted along with the res of the exposed...
