    820-3332 lcd enable

    i cant get lcd enable to be sent, i can force backlight, i reflowed u8900, but was missing some rails, so i replaced it and the rails showed up, i now have pgood, but no matter what ive tried i cant get lcd enable to come on. im almost 100% sure this lcd is fine.

    820-3332 no internal display

    no i touched up all the solder joints on u9000, i just touched up u8900 even tho it looked fine and its lasting longer than 20 seconds this time, "jumper removed ofc" so i guess i had a bad solder joint, but i wounder would my jumper have caused any issues?

    820-3332 no internal display

    i have a 820-3332 that came in for no power, after diag realized its powering on fully just no internal display, checked smc_lid and realized it was 0, repaired and got screen for about 30 seconds, then black. figured out after a few seconds i lost PP5VR3V3_SW_LCD_ISNS, so i jumped it from pin 2...

    820-4924 no battery

    ok so i guess im gonna ask a stupid question. how does one remove corrosion under the plastic battery connector if ultrasonic does not remove corrosion.

    820-4924 no battery

    i ultrasonic-ed it once already, should i give it another go? and this happens with all batteries i put in, so it cant be a bad battery

    820-4924 no battery

    sorry inm not to sure what to do from there, the 10k resistor is good, so why is it not pulling down. jumping pin 1 to ground workes to stabalize battery power,
  13. A

    820-4924 no battery

    yes ppbus stablized and so did the power pins, tho it won turn on. im guesing bc its shorted to ground battery wont work
  14. A

    820-4924 no battery

    the 10k resistor is measuring 10k ohm and yes its pin 2 is tied to ground so it should be pulling down
