The tv is completely dead, no standby led nothing,, measured voltage across main caps and found voltage fluctuating around the 160Vdc range..
located 2 bad parts in the LED drive circuit,, Driver IC AYN6HB and an FET.. i can find a replacement for the FET fine, but not having any luck locating the driver IC.
I removed both parts and used my led tester to supply voltage to the backlights but the tv will still not turn on..
voltage on all of the regulators is 0V
Does anyone know what a replacement driver IC would be for AYN6HB and also can give me some idea where to look for the power on issue,, can't find a schematic for this unit anywhere
