    OK. Can you check if anything happens when you try both orientations on the USB C connector? Check that you are getting charger voltage VB on pin 9 if the M92 and similar output VEX to the BQ on pin 28 of the M92. Check internal power...

    Have you checked the fuse? Let's start from there and work from that. Search the forum for pictures and location if needed. Sheriff Sent from my SM-G975F using Tapatalk

  4. SheriffBuck replied to the thread Black Screen issue after replacing BQ Chip.

    4v isn't enough to drive the backlight. That's either backlight "off" or there is a fault. You should expect 17v here. Sorry if this sounds offensive, but some of the items circled are inductors and will test as shorted. You may only have been...

  5. SheriffBuck replied to the thread SX Lite blinks blue and green but the screen doesn't turn on.

    I've had one of these. It's extremely easy to damage the connector and with the backlight delivering 17v, its very easy to trigger a short and burn the track out. It's a compromised design frankly as it's hard to disengage the power with the...

    That's great news. Can you offer a step by step on the process for anyone that may want to have a go at doing this operation themselves please? If certainly appreciate how to reflow the ram.... S. Sent from my SM-G975F using Tapatalk

  7. SheriffBuck replied to the thread What does pin 34 on m92t36 ic do?.

    Hi, Pin 34 is a setting pin for dead battery scenarios and may not actually be connected to anything. I can check it for you when I get back to my bench next week. It may well be wired the same way as pin 33, so you may want to check that. It...

  9. SheriffBuck replied to the thread Capacitor in short circuit.

    This is a smoothing capacitor that sits between VBus from USB and ground. If you've got a short here, then you want to check your USB soldering if you replaced it or for bent pins, the two large mosfets that hang off this line and finally the...

  10. SheriffBuck replied to the thread Error Code 2101-0001.

    Just to add my thoughts on this one. If you remove the M92T and power up, you get this error. :) @Pintglass and @FXDX are on the money here.
