I am looking at the schematic and i dont understand why is it important to have a 0,1 Ohm resistor. Does it have to do something with the 2 mosfet (Q3 and Q4) in series? What if i just replace it with a wire? thanks

Can you post a link to the schematic? Why do you think shorting out a resistor and it will work fine?
The resistor has a purpose, it failed because the mosfets are shorted. -
The current resistor also plays the role of a fuse, if the Mosfets burn out, then they take with them the SMD resistors, diodes, zener diode and PWM, definitely change the PWM (if you don’t replace it, the Mosfets will burn out instantly the first time you turn it on) and check everything else...Attached FilesComment

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi
I am trying to repair an ancient Dell 2209WA Monitor which suddenly shut off with a pop sound. On investigation found that one of the fusible resistors had blown. Further investigation identified multiple components as faulty because of which the fusible resistor blew. Please refer the attached circuit diagram showing the components that were found to be damaged.
1. FR950 - blown fusible resistor - 0.2 Ohm 1W
2. Q950 - shorted Q950 MOSFET - 650V 10A N Channel Mosfet
3. R835 - Blown Resistor - 20KOhm SMD resistor
4. D930 - Shorted Schottkey Diode... -
I have a quad charger that is split into 4 separate sections and one section doesn’t charge anymore. I have located what I think is a thermistor and on the shrink tube it says 125 degrees C. I cut the shrink tube and it's a 33 ohms resistor. It measures a little less than 1/2 inch in length. I am including pictures of it. Please help me identify it. So, it should test at 0.4ohms and probably go up in resistance with the rise in temp. On the board it clearly says R for resistor. But it has to be a special one.
Resistor shows orange range silver gold and green lines.
Thanks in adv... -
Hello guys, I had a problem where I didn't know the value of the burnt SMD resistor in the power supply circuit of the BenQ G922HDAL monitor.
In one of the parts, there is a burnt SMD resistor which leads to the LD7560GS IC as shown in the picture below.
How to determine the appropriate SMD resistor value for this condition? Thank You... -
