Good day everyone,
Let me preface this with letting you know that I have a smalltime computer repair shop but do not have a lot of experience when it comes to board diagnostics. I am good at soldering etc but finding the issue if there isn't an obvious burnt component is not my strong suit.
The other day I got a customer come in with a macbook A1990 (motherboard 820-01814-A) that would not turn on and had previously been getting the warning message that the battery needed servicing. (Most folks seem to ignore that message, just like the check engine light in vehicles.)...

by jason123Hi all,
got this TV for a friend to look at. Non-responsive to PWR button. Main board gets warm, the the optical audio light is on. Faul pin is zero volts. I am getting 33v on Vdrive. 12.76V on B13 & A13. Vamp is 17.3V.
Disconnecting panel cable to main - no change. Disconnecting small ribbon from main to led driver board, backlight comes on.
Do do you guys think? I am thinking main board issue?... -
by AndreasbestHello!
Today i received a Legion 5 pro with motherboard NM-D562 that suffered water damage, no power at all, no led, no fans, nothing.
I measure 20v on PQ5401 at pins 5, 6, 7 and 8 but 0v at 1, 2, 3 and 4.
Is this normal?
Thanks in advance!
