    philips 42pfl3704d/f7 resistor size

    I am working on this tv and I found some bad resistors. R603, 604,605,606. If I look at the parts list of the service manual it says they are 470k ohms 1/4 watt. What is on the board and all the resistors in that area look to be 1/8 watt in size. Is this a service manual screw up or a design screw up. Scratching my head.

      Going up on wattage is fine.

          Problem

          This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

          Does anyone know the value/size of the cap and resistor where the thumb is?

          Thx...

          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...
