    Audiovox FPE3706 clueless

    This is my neighbors TV that was under a blanket in their garage. The main power supply fuse is good, I have never heard of TL capacitors so I switched them all out for UCC KZN/KZM series. The 2200uf 35v cap had a failed bottom bung and I multimeter handling failure made me think that the 470 ohm 5W fusible resistor had also failed open. When I fired it back up, I was showing good 5v standby voltage. I pressed the power button and heard a distinct POP. I figured the fusible resistor was gone again but it tested out at 450 ohms. I also noted scorch marks around one resistor (R558) that I believe is marked 70 ohms. It metered as 10 ohms ( still in circuit). Checked all the SMD fuses on the inverter board, they are good. Any opinions? Thanks!

      I guess I should include that the original gripe was no picture, no backlights. Power light shows on.

          So what DC voltages do you have at the connecor now?
          Willing to help but I'm no expert.

                  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 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...

                  What are the pro's and cons of replacing a 1/4 with a 1/2 resistor same ohms?
                  by Baste
                  Hello,
                  As the title says. I bought a cheap Asus ROG Strix 750-watt PSU, which was posted as defective. Cables are complete, and the entire PSU is in good condition, of course, aside from being faulty. Long story short, upon checking, there is no +5VSB. Looking at the components, I found a blown resistor. I swear, looking at the bands, the color is pink, pink, gold, gold. I dunno if I'm color blind or this is the way resistors are coded.

                  Please help, did I decode it correctly at 2.2 ohms (red, red, gold, gold), or what could a pink, pink, gold gold value be? I bought a...

                  Is this a fusible resistor?
                  by bluto
                  This is from the power supply of an LED shop light. The light went completely dead suddenly. I removed the SMPS board and it looked really good except for some bad solder joints. I touched all of them up but the light was still dead. I then found this open resistor that was between the neutral wire of the plug and the transformer. The color bands seem non-standard. Does it indicate 13 ohm, 30 ohm...? I am not sure. What should I replace this 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...
