    lg 34px3rva

    Hi folks
    1st post so apologies for any noobiness

    Ive been given an old LG plasma to look at 42px3rva which has the seemingly common sound but no picture problem.
    I opened it up and saw a blown 350v cap on the y sus (c26 I think) which I replaced.
    When I put it all back together a resistor right next to the cap glowed red and blew.

    Now I cant see what value the resistor is.
    So, 2 questions please
    Is it common for it to be another failed component on the y sus which has caused this and if so is it worth replacing the resistor?
    Does anyone have a schematic for this board or otherwise know the value of resistor I need?
    Many thanks

    Andy

      Sounds like a power transistor or something has gone shorted.

      You need to upload photos of the boards, the whole TV with back off, the damaged area, etc etc.

      Also, check the model number, Google only returns this thread as a result so I expect you've got the number wrong.

          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

          Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
          by chth96
          I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
          Since then, This AC/DC adaptor have been out of order.
          But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
          After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
          Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
          And Is there any possibility that it will suddenly explode as well as to be out...
