Mac works normaly on battery but when i plug megsafe charger the board is going hot and charges to much amps .
also pin 17/18 on u7000 resistance is 150 omhs ??
fixed backlight bad chip .
"pin 17/18 on u7000 resistance is 150 omhs"
You mean U7100; fix that problem.
Check R7150-52, their traces and solders to U7100.
I hope you talk about resistance between pins, not to ground...

it turns now ON ! when i unplug the LIO Connector it turns on but when i plug the battery its charge to much amps . but it stays on with battery when unplug charger ?
I tries 3 lio boards and flex cable still the same board looks clean. The problem is only when i plug the battery in and starts charging to much amps .
"The problem is only when i plug the battery in and starts charging to much amps
----------------------------
it turns on only on battery without charger but dont charge"
You really mix the things and make hard to understand you.
Don't charge, but take too much ampers charging; very unclear/confuse, as I said...
Please specify:
- does it turn on on charger only?
- does it turn on battery only?
- does it turn on with both charger and battery connected?
And use original Magsafe 2 charger!!!
- does it turn on on charger only? --- Yes only by SMC bypass !!
- does it turn on battery only? ---- Yes , just by pressing power button or shorting smc_onoff !
- does it turn on with both charger and battery connected? Yes , but the board is getting Hot on both magsafe2 and powerDC !
