IN MY VIDEO I'M DEALING WITH FULL HD 40 INCH DISPLAY PANEL, THE SET WAS GETTING ON WITH ONLY BACK LIGHT OK BUT NO DISPLAY, WHEN I DIAGONISED IT, I FOUND THE VAA(AVDD) LINE ON SCALER PCB WAS SHOWING 48 OHMS ON COLD TEST METHOD WHICH WAS ABNORMAL, FOR CATCHING THE EXECT SHORT COMPONENT, I HAVE USED 4 CHARGEABLE BATTERIES OF 1.2 VOLTS(2700 MAH) IN SERIES FULLY CHARGED, BATTERY GROUND ON SCALER GROUND AND BATTERY POSITIVE ON VAA POINT, AS I'M APPLYING AROUND 5 VOLTS ON VAA(NORMALLY 16 TO 17 VOLTS), IT IS SAFE THAT NO OK COMPONENTS WILL DAMAGE, AFTER CONNECTING THE BATTERIES I FOUND ONE PF CAPACITOR WAS OVER HEATING, I REPLACED THAT PF CAPACITOR WITH NEW ONE AND MY DISPLAY WAS PERFECTLY OK, HOPE YOU UNDERSTOOD MY POINTS, FOR ANY QUESTIONS PLEASE COMMENT ME, THANK YOU FOR MORE EXITING TIP'S ON LCD AND LED REPLAIRS PLEASE SUBSCRIBE MY KZread CHANNEL THANK YOU🙏.
