    So... Blue screen console. I baked it with my usual process 350 F for 7 minutes. Console does not display anything now however, is recognized by my computer when put into RCM mode. Nothing happens when a payload is injected.

    Charges normal, 0.42A. Voltages around M92 seem reasonable. Thoughts?

    LCD does work, I did verify with another console.

    After plugging into charger with good bat, it never boots / kicks up to fast charge.

    I've seen this on many consoles and have never successfully fixed (blank screen but charges normally).

    I have replaced BQ/MT/P13.

    Almost like my Switch I've got from ebay.
    At first I had a blue screen, I pressed hard on the SOC and it stopped showing blue screen.
    Now the screen doesn't show anything, even the backlight will not turn on.
    Slow charging appear to be fine at 0.4A, didn't find shorted caps.

    you have a shorted Tegra chip, probably the board has flexed at some point and some solder joints are cracked.

    one of my switches had the same and after a reflow I found a shorted rail where the MAX chip near the left speaker connector, and I ended up taking the Tegra chip off .. short was gone around the board. I havent put it back on since i have broken pads (this board was badly bent tho..) if I get to fix it.. Ill let ya know!
