After changing the faulty backlight and solving one of its problems, we found that the equipment kept restarting itself after being turned on for some time. | We found the ic408 on the main pci with leakage, it is a normal npn transistor. Just put some heat on it with a thermal blower and the TV will restart itself, so just change it and it's sorted. | EC | |

Turns on but the backlight lights up faintly, but very faintly | As is customary, a budget for LEDs was given, surprise when changing the kit that the TV lit the LEDs very weakly...the voltage that went to the LEDs with the defective TV: 81volts...after the voltage was resolved The LEDs went to: 117 volts.. | Cw21 of 1μF smd next to the c.i drive uw4 ( ob3352cp) was shorted and also the smd resistor rw48 ( 10Ω smd). It is difficult to find the datasheet of the ob3352cp which is different from the ob3350, sound is the pinout that I found by analyzing another board: pin 1- out for the LEDs (gate in nomenclature), pin 2- gnd, pin 3- sense in, pin 4- ovp, pin 5- inn bl adjust, pin 6- cmp (i.c decoupling), pin 7- bl_on (backlight enable), pin 8- +b 12 volts. | MIGUELTV |
