Hi...
For all about say WITHOUT TRANZISTOR solution !!!
Please read here...
One copy display..or original display need 5.6-5.9 Volts for good light..
The display led is in series vith board led.....
In schematicd...Vled- Vbat=Vdisp+Vboard=5.7V+3V=aprox 9V...
VLed= aprox..13V
How can..without tranzistor(inverter)..with 3.6V on Vbat....power the 5.7V led?
Is simple electronics here...look on schematics....
Only solution is replace transistor from inverter( ok...repair inverter)..or change display led with one at 3V and put in paralel with board led..
TNX...
P.S. For all who want without transistor solution and all who put smooth picture on forum...
