    Bush LCD42F1080P

    Hi,
    I have a power supply from this set which has the 3.3v missing. I've replaced the psu since I could not read the IC's that were damaged which were on the 3.3v line but was able to identify their part numbers when the replacement board arrived.

    The two IC's have been replaced but I still don't have the 3.3V supply.
    To test the other supply voltages I tied 5Vs pin to ON pin. (connector P201)
    Do you have to do something similar to switch on the 3.3V supply.

    Power supply board number is 6709900016C which I believe is also used in the Wharedale 42F1080P set.

    The testing has been done with the power supply on the bench and all cables removed except for the power cord and the one jumper mentioned above.

    If the circuit diagram is available then better still.
    Thanks

      The supply should be a 17pw16 for the model tv.

        Hello ReeceyBurger123,
        Thanks for pointing out my error. My fault in that I labelled the power supply incorrectly before putting it away. The picture is of the power supply I'm attempting to fix and on double checking it came out of an LG37LB1DB-EC set and not a Bush as I original stated.
        Thanks for pointing it out for me.
        Again if anyone has the schematic for the supply and would be willing to share I would appreciate it.
        Regards

          No problem haha we all make mistakes. I will see if I can get a schematic for you

              Hmm cant seem to find one for the psu, however I do remember there was a tread about this psu with the exact same issue as you have so will see if I can find it.

                Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
                by Tynan Dill
                I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

                Upon bringing it home and plugging it up, it showed a standby light.

                I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

                The screen seems to blackout and stay black, but with a flashlight I can see the display.

                With my Playstation 4 connected via HDMI, and running a game I can hear sound.

                Assuming...

                Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
                by sam_sam_sam
                I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

                One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

                Modification to a ZD-987 desoldering/soldering station using a external switching power supply
                by sam_sam_sam
                I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails

                I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time...

                Definitive technology SC 2000 subwoofer amp's power supply clicking and popping
                by JimBanville
                The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
                Opened it up and discovered the power supply is making a faint clicking or ticking sound.
                I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
                I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles...

                555 based power supply getting too hot
                by madan1
                Good day.
                I have an AC/DC -> DC PWM (rectifier + 555 buck converter) power supply with MDF11n60, which is getting very hot.
                The input is AC from a transformer and the output powers a 24v dc fan. The power supply is used to regulate the speed of the fan.
                After several runs on the bench power supply I noticed that the mosfet is reaching 80+C*. The mosfet reads fine on component tester, the thermal paste is changed, the fan is cleaned and with freshly oiled bearings.
                When powered directly from the bench psu, the fan takes ~0.7A on 12V. The current consumption is similar...
