    Help identify a resistor

    Hi,
    Recently i kind of busted my Proskit
    MT-1210 digital multimeter by putting my probe on a hot ground instead of cold ground while measuring a diode on secondary power rail.
    My issue is I am trying to test and replace any damaged resistor. There is one resistor on the left bottom part of the colour green,silver,white,white,black. Can anyone advise on what is the value and how do i test it on a dmm. Appreciate all the kind suggestions.

      Which resistor R?? the colors you mentioned would be 0.99Ξ© 0.5% I see part of a resistor stuck to the greese on the bottom left of your picture.

        I think the OP meant the one near D1 on the upper left, probably because the picture is now rotated CW by 90 degrees from the description?

        Either way the it would be tough if it actually discolored due to heat. That picture has a lot of weird things in it...

          Hi,
          Identified the resistor as 0.99 ohm and tested it as working part. Eventually found out a damaged resistor at R27 (600ohm).
          Now i can go ahead with the repair.

          Thanks for all the input.

            Dell 2209WA - power supply - Fusible Resistor replacement
            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...

            Can a resistor lose resistance after hot air?
            by MidnightRoller
            I am curious if a 0402 resistor could go from 43 ohm to 0. In electronics class and my experience a resistor can degrade and gain resistance all the way up to not being able to conduct at all. I have never heard of a resistor decreasing in resistance and becoming 0 ohm or a dead short… that's not the direction they fail… or so I thought.

            I was attempting to remove a wson8 chip on an iMac motherboard and it required a lot of heat, on one side of the chip were 3 0402 resistors that were very close. I popped the chip out unintentionally out of the tweezers and sent those resistors...

            What resistor ohm will work better to repair this waterpik?
            by artvandalai
            The resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y
