Burned LED panel (03 rulers with 08 LEDs each ruler and the LEDs are 6v) and each LED has 6.6 volts on top of it.... | Modification to reduce current (link on YouTube the nel 350: https://www.youtube.com/watch?v=fliqgp62tps) and then it deals with the tc-40d400 but the power supply is very similar to 40ds600b | Modify resistors r7837(1r), r7835(1r), r7826(1r), in my case I modified them to 2r7 and the voltage dropped from 42 volts to 38v. detail that the manμFacturers are dishonest and when you turn on the TV the voltage comes at 48 volts, then the pwm corrects it and drops to 38v, turn it on today, turn it on tomorrow and tsound it goes... in other words with this voltage above normal over time The LEDs will definitely go out... | MIGUELTV |
