MB Air A1466 - No backlight after liquid exposure. What do we need to test, and/or replace? Thanks as always. Picture attached.

This repair is successfully completed. Thanks again for another very happy customer and helping me further develop the skills our shop has to offer.

MBP A1278 - Won't power on, only green light on charger, but dim blinking orange light. Minor liquid exposure and some corrosion noticed in the area just to the right of the battery connector on board. Is this worth attempting repair? Should we do testing to pinpoint what components need to...

Well based on some of the discussion on here the JBC seems to have no drawbacks (except cost) where I have read complaints, or disappointments in the overall experience of using both Weller and Hakko comparable products. Whatever we buy, our shop will need use this hot air station every day...

I am happy to report that our shop has finally earned it's way into being able to afford a JBC hot air station. The JBC people in St. Louis say the JBC JT-1D is the same as the former (discontinued) JBC JT-1A. Can anybody share personal experience using the newer JBC JT-1D? Are there other...

Still has flicker even with the Battery Indicator Lights disconnected from the board.

Are you referring to the LCD display connector?

Okay the flicker is not as bad at the moment, but it has been to the point where it's as if the backlight is flickering completely on and off. Also the backlight goes completely out when the charger is connected. If you connect/disconnect the charger repeatedly the backlight will come back on...

I just noticed all of your responses. Thank you so much. I still need help with this, so let me first get the short video uploaded later today, and then I will also follow the other suggestions. Thank again.

Hey guys I could really use some guidance on the above described issue. Should i just try to reflow the LED driver chip. I have already tested the LED fuse and it seems to be good. Thanks.

New cable solved the issue, again I can't thank you guys enough for offering this service and the YouTube channel. I have learned so much in the last six months. Look forward to how much I will learn in the next six months. :cool:

Looks like both of these cables I have are bad. I get 3 of 4 beeps on one of them, and 1 of 4 beeps on the other. Ordering a new cable, hope its good and will respond with update. Thanks again.

Thanks. I have verified that I am in fact using 2012 type flex cable. It did however come off a donor machine. Is there a way to test the cable with mutli-meter? I have tiny tipped fluke leads, that with enough effort I can probably get on the appropriate pins. Thanks again man you guys are a...

Thank you.

I am trying to find the board view file for this model. I did manage to get Open Board Viewer installed but I still need the file for this model MBP.

It is more stable with the kb and tpad disconnected but the fan kicks on and will not shut off since i disconnected kb and tpad. There is not corrosion at all. bad U5700?

Update: When the trackpad is disconnected it seems to be a little better but the a external USB mouse I have plugged in freezes for moments. Touching the trackpad connector when trackpad is plugged in seems to make mouse pointer glitch slightly.

MBP 13" Mid 2012 - Erratic mouse pointer, moving and clicking random places, opening windows and menus, without user input. When track pad is touched it seems to lose connection or drop before pointer can be moved one place to another across the display. Replace trackpad? Board problem? A...
