    Re: Honda XL 600 LM 1985-1989 PD04,Resistor blown up and losted

    What is the IC's part number? Is this a tachometer?

    i missed that, was looking at the discoloured one.
    lets see the track-side to see what it does

    2 ceramics, 1 tantalum, 2 diodes and a chip to test too - i doubt that resistor killed itself anymore than epstein did

    R2?

    That's going to be quite hard to figure out what it was, I was wondering how to derive 9Ω or 39Ω from a missing resistor... probably will need to locate an identical board or do a complete reverse engineer of the board and where each wire connects ...

    9ohms or 39ohms
    remove it to test it - then test that zener diode thats probably shorted.

    Hi guys a friend of mine give me this old counter it's for Honda XL 600 LM 1985-1989 PD04.
    He opened it and found a resistor that was blown up. Then he lost it. I knowing it's not easy to fix it, but I just guess (maybe we can) thank you so much

    Sony Bravia KD-50X690E blown resistor
    by x_orange90_x
    I just picked up this tv yesterday and the previous owner said while watching tv he heard a loud a pop and then the screen went dark. I removed the back cover and found the source rather quickly; resistor R8601. A chunk of the ceramic had blown off exposing the inner wire. Due to the damage I cannot make out the colors of a couple bands. I likewise cannot find a datasheet for the power supply. I tried pulling up pictures of the same board online but the resistors have different colored bands which I half expected as I've had this happen before.

    The power supply is 715G8413-P01-001-0H2S...

    Arcade PSU blown resistor ID
    by redbaron1007
    I'm working on one of the PSU's in my backlog today that came out of an NBA Jam arcade machine a year or so ago. The PSU is a Pan Yes brand with a model number PY-TV-C. From what I remember the 12v rail wasn't outputting anything. I opened it up and was reminded that the resistor at R28 had blown it's shell off and I have no idea how to ID a replacement for it. (see pictures) The color bands that are still intact a little are brown, black, missing band/bands, and what I'm assuming is silver. When I check it with my DMM it's reading 100ohms exactly but I don't know if that's what it's supposed...

    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
