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...

Hi everyone,

Sorry for the person who’s going to read all this !
I'm on a Nintendo Switch Lite, motherboard HDH-CPU-02.

While replacing the left joystick, I had to remove the motherboard to access the connector underneath. When I lifted the LCD connector latch, it broke (the plastic had become brittle over time), so I replaced the entire connector.

During the desoldering of the LCD connector using hot air, three small components located just below the connector (likely 0402 capacitors) came off and remained stuck to the bottom of the...

Dear All,

I need assistance creating clearMe bios. The laptop is shorted PCH, after PCH replacement laptop can ON but cannot boot. Power supply current reading is 2.5-3.0 Amp.

Model : G512LW-WS74
SN : LCNRKD009429512
CN : ANE9

Attach backup bios.

Thanks for your help.
Best Regards....

While removing the glue, I tore off one resistor, marked in the photo. If anyone can, please measure it and tell me its value.
Regards.

Hi to all forum members,

Got this faulty 350 watt atx psu dirt cheap from a local online seller as i am keen to use it as a learning tool to repair faulty power supply.
The faulty part is quite obvious from the burn area near the 16pin KA7500 BD pwm. The fuse is still intact with good continuity.

Upon power on ac, there is 5vdc standby power on cathode of diode D14 and about 10vdc on cathode of diode D13.(This should be the aux power to generate the 12v and 5v rail.)
Initially i replace the two burned resistors near my marked red arrow to 200 ohm resistor...
