no backlight after water damage.
Hello.
You're doing great job here!
I would like if you could help me too.
I have Macbook A1278 with 820-3115-B motherboard after water damage.
There is no backlight of screen (flashlight trick works) and keyboard. I check voltage :
I2C_BKL_1_SCL 3,3V at R9753
I2C_BKL_1_SDA 3,3V at R9757
LCD_BKLT_PWM 3,3V at R9704
PP3V3_S0_BKL_VDDIO 3,3V at C9711
PPBUS_SW_BKL 12,4V at C9712
PP5V_S0_BKL 5V at C9710 and C9714
PPBUS_S0_LCDBKLT_FUSED 12,4V at F9700 and on out Q9706
PP3V3_S0_LCD 3,3V at R9008 and R9009
PP3V3_LCDVDD_SW 3,3V at L9004
PPVOUT_SW_LCDBKLT 12,4V at C9020
PPBUS_SW_LCDBKLT_PWD 12,4V at R0910 and then 3,06V at R9715
and there it 0V at BKL_ISEN1,..,BKL_ISEN6, so this is mean that U9701 need to be replace?
Albo Magsafe works 1 on 5-10 tries. I have to plug it slowly and then there is green light and it starts (no battery inside).
Please help me with backlight and connector.
Thanks in advance.
PS: Sorry for my english
Questa è una buona domanda?
Did you check Q9707 to see if the backlight gets enabled?
