    Haier HLH376bb not powering on opened to find issues

    Hi all

    any help you can point my way is much appreciated

    so I have a Haier HLH376bb with powering on issues I have opened it and found a bad cap and in the removal process as it was glued down with the white glue I also broke a resistor which was right above it on the board me and my fat fingers

    I have already got the service manual for this set but I'm not really clued up enough to understand it yet and my main questions what replacement cap and resistor do I need I looked on digikey and trying to work out the right parts completely lost me as they have about 7 or 8 pull down menus asking for info that I don't know

    I have attached pics of the bad cap and the resistor and the board and uploaded the manual for anyone that can help me out

    once again thanks everyone for any help you can give me

    the resistor is R41 on the board and the cap is C32

    The resistor is 0.22 Ohm MOX (Metal Oxide) type, 1/2 Watts. You should measure the resistance, it may be OK, you have just scratched off the coating but did not damage it.

      However, the coating forms part of the flameproofing, so would be best to replace for long term safety and to prevent further damage in case of failure.

      If you make an order with Digikey you can get both at once:

      (Cap -- looks OK -- check dimensions)

      (Resistor)

          Re: Haier HLH376bb not powering on opened to find issues

          For the cap, I just searched 150uF 400V in Digikey, selected the first one with leads from a respectable brand. No narrowing it down - Digikey website found only the caps matching my search. For the resistor I searched something similar to 0.22 ohm and this was one of the first results...

            Wow thanks to the both of you for your help in tracking down the right parts just ordered them from digikey once I receive them next week and there installed I'll post an update hopefully all will being working placing this Lcd as number two that I've repaired

              Did you check that capacitor before you ordered would fit?

                Yep the one you found was slightly longer but there is space below so hopefully all will be well

                  hi tom66

                  so just got the parts back from digikey the capacitor is spot on but the resistor you found is completely different as you can see in the pic's below not that I'm complaining because its no big deal as they were only a few cents would you be able to find the right one Ive tried looking but again but I am still a bit confused with selecting the right resistor and also they may of just sent me the wrong part if so I can send them and email I've added some measurements to the pics this time to help in finding the right size

                  the color bands on the old resistor are red red silver gold
                  and the new are red red silver gold white

                  once again thanks for the info and any help you can give

                      dear
                      Original register is 1/2 watt but new register is 1/4 watt so please find 0.22 ohm 1/2 register

                        Use the Digikey search box. I am not an automated ordering system.

                          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...

                          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

                          Hoover FM216LI cordless vacuum refuses to charge
                          by flat-earther
                          I have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.

                          I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
                          5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.

                          So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries....
