This device came in as a liquid damage machine. There was very little corrosion on the board and all of it cleaned up very well. It appears to power up properly, drawing about 2.3A. If I let it sit long enough I get a couple of faint vertical lines on the screen but no picture. With LCD...

This customer has now been here three times with his A1989. He reports the complaint as closing the lid in the morning, battery at 100%. After work, he notes before opening the lid, the device is very hot. He opens the lid and the battery is much lower. Until now, I have not been able to...

No lights on charger. .369v @ L7095. Injected voltage at L7095 but all which heats up is L7095. Where to go from here? **UPDATE** Never mind. There's a ton of liquid damage on the underside of the board.

I re-checked, and yes, there are .300v on L9580. I found one on ebay.

.OL on all coils page 92 except L9521 = .177v and L9530=.300v

This device came in as a No Power complaint. I noted 5v .400a on all 4 USB ports. Verified no DFU. Noticed U9500 was getting hot and at this point, I noticed we had 20v. With battery charge ribbon cable disconnected, drawing about .150a. With battery charge ribbon connected, current climbs...

Thanks!

I actually can't even see the board number anywhere on this device. I looked it up on ebay to get the number which is apparently 821-04012. It's A2941 SN:LKXCDX6D7P Anyhow, the customer says they spilled liquid and now the screen doesn't work. External video is working, lcd panel is on...

This is a 820-4924A A1502 model. The backlight is intermittent. Worked for an hour, then went out. I was checking the board for damage and I found heavy corrosion at Q7700 P1/2/3. I removed that component and cleaned the pads. I've got continuity between pins 2 and 3 and from the schematic...

I have not tested external video with the internal LCD disconnected. Here is an edited picture showing the white line.

A2141. When I power this up, I get the power chime, but then all I'm seeing is this single horizontal white line across the bottom area of the screen as pictured. I have connected this to an external display but I am not getting any output there. Does this seem like a board issue or screen...

That's got it working. Thanks!

Trace repaired. I now have .135v on C8411p1. Should I have 12v there with power connected but screen disconnected?

I saw it lol.

OK, a display from Mobile Sentrix, but still not working. I may be on to something though... this is right where the damage was - see image. I also have 12v on C8401p1, but no voltage on c8410p1

OK, that's why I asked haha. ok, I'll just buy a screen for testing.

This is a A2159. Will an LCD panel from a A2338 work? I have one of those I can test with.

I have 3V3/5V_S0SW_LCD. I do not have power on J5100/10.

A2159 came in for no power, liquid damage(see attached image). I cleaned the corrosion from those two locations, and noted that the USBC pins on the power board were burnt from the event, so I replaced that board. Machine now draws reasonable current, running at 20v properly. I have a hot...

OK, thank you for all your help! See you on the next one!
