    Resistor value identification

    Hi guys, what is the resistor value of R7201? Not sure.

    Thank you

      Can it be 1,78Mohms?

          No. The '1' is a bad cad to pdf conversion sideband issue.

          Which exact model are you reviewing? Which motherboard? The shared screen does not display the required details.

              Hi mon2, LENOVO Thinkpad P1 Gen2 - Wistron 18809-1, schematic attached. R7201 position, marked as "1D78MR2F-GP".

              Thank you

                  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.

                      Nice find. Never noticed that before, thought it was a manufacturer part number or something. So the D probably stands for decimal. So....

                      1.78Meg 0402 1% tolerance

                          I decoded it for 1,78Mohms too...

                              by jinu_j
                              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...

                              Need help to replace burned resistor in 350w atx psu
                              by mikey5791
                              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...

                              Klein MM400 resistor identification
                              by redbaron1007
                              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...
