    TV resistor not making any sense

    Hello, I'm having an issue determining the value for a 5-band resistor on my LG 42PJ350-ub power supply. The bands in order are: Orange, Blue, Silver, Gold, Black. Tested out of circuit returned .6 ohms. To my knowledge this color combination should not be valid; and I'm hoping someone more knowledgeable than myself may be able to decipher this code.

    What resistance do you get when you touch your meter probes together? about 0.3 Ohms, then that is correct 0.36 Ohms + 0.3 Ohms for the meter lead. This resistor when it failed, it will usually go open circuit.

      is looks more like inductor to me http://cdn.instructables.com/FRQ/J6V...NQFK.LARGE.gif

        It's a 0.36 5% wirewound-resistor.

        The marking color "BLACK" means manufacture's series .

        Some for Nonflame type with BLACK marking ; or
        non inductive wire wound resistors(無感繞線電阻) ---> GREEN
        inductive wire wound resistors(有感繞線電阻) ----> BLACK

          This resistor is probably for the Source pin of the MOSFET or fusible resistor for the B+.

            The value must be right,i have here a fusible resistor marked .1ohm 1/2w 3% and it measures on my 87 fluke .3ohm,when i tough both probes together i get .2ohms since it's 3% tolerance then is within specks.

              Need help to identify and to locate a 0.33 ohms fusible resistor for power supply
              by gica69
              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...

              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...

              Replacing a Current Sense Resistor
              by Darren Hibbert
              Hi.

              Quick question.

              I have a laptop that is completely dead. I opened it up and it looks like the current sense resistor is blown. However, because it's blown, the value printed on the top has disintegrated and there is no schematic available for this particular laptop (Dynabook Portege) so I'm not sure what to replace it with.

              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...

              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
