One time I'll try do that , the tv work fine, but after short time can back, may be the power MOSFET of forward work so hard with 300 volts. Hope you are lukie this time. Excusme my bad English, Im Spanish from Argentina.

Hello Tevz I have been very trill with your levelled deep and vast knowledge in electronics I really appreciate your relentless instructive posts of which am one of most benefited .may GOD reward you, I had a pfc issue with 26 inch Samsung lcd when I did the bypass it couldn't work .Please help how do I boost 300vdc to 390vdc to make it work thnx a lot

@tevzTVTevatronics 2 ай бұрын

The only way to boost it to 390 volts is to repair the PFC. There are resistors connected to the main capacitor that you can modify to somehow start the main power supply. Example a resistor connected to b+ of the main capacitor value of 3.3 mega ohms. try to parallel a 2 mega ohm of that resistor which is connected to the B+ main capacitor.

Pienso que para aumentar la tensión de 300 voltios se podría intentar hacer un doblador de tensión como traían los viejos tv de TRC que servía para trabajar con 110 y 220v.

why did you cut the trace that power the PFC circuit IC? removing the PFC transistor and diode was not enough?

If I was the customer and saw how you undertake this repair (if indeed you are actually repairing it) I would ask for a refund and take the TV elsewhere. Absolutely brutal removal of components with the least possible amount of tools - try solder wick
