Page #2 has a resistor part decoding scheme posted. Suggest to hunt for other schematics with the Think Engine part to compare this value. Will review later.
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.
hello, i have the gpu in the title and a resistor fell off that i need help finding the resistance of. does anyone have the schematic or the resistance value? see images below for the one missing....
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...
I managed to blow the fuses in my Klein MM400 multimeter and when I replaced them I was still getting a cal and error0 message. I started looking around the board and found one resistor that was testing OL and has a visible burn mark on the top of it so I can't tell what the value is anymore. Its marked as R19 on the board and I included a picture below of what it looks like.
Does anyone know from working on these what the value is or have this exact meter they could open up and check the value? It's not my only meter, but it is my first real non harbor freight meter...
