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. If there is a short circuit in the circuit again after the repair, how will you notice the short circuit despite putting resistance in the circuit input
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
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.
Resp Sir! Very Nice Sir. Sir My HP Monitor Balack Sreen CPU Connected after Vertical Lines Sir Where the Problem Sir Please Advise Sir. -- ChinnaRao Paderu Andhrapradesh
hello your video concerning food interests me. I have to admit that I didn't understand anything. can we remove the mosfet and cut a line and it works? help me I don't understand. I want to understand .
sir i have a question about mosfet removing and replace to wire from schematic if you 300v and gnd are connected i think a short have can you explain pleaase and big thank
when turned on, there is no image, the indicator is still on, the screen lights up, there are black stripes on the candinsator for the backlight, 40 volts.
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
