i have V3X no light on LCD and no dISPLAY

ALready changed LCD,FLEX, not help..

Check the PCB board for liquid damage. Sometimes after a long period the board becomes greassy try to give it a 30 min isopropenol bath see what happens. Or u can try to reheat the board so that all the chips resolder to the board. your choice :d

Hi
Damaged or broken Testpoint resistor is usually the cause of this....especially after an unlock attempt.
Remove Testpoint resistor and make jumper over those 2 points....or solder jumper on top of Testpoint resistor.
Good Luck.
