    Re: Fixing a DAC-19M005 Power Supply - check my DX:

    Hello Guys I have a blown FET Q206 and resistor R210 burnt.
    I understand from previous posts that R210 is 10ohms ,was wandering which transistors are Q201,203,204 and 209.
    Also can "blackrider1" please post the schematics again as the Megaupload site has been taken down.

    Thanks
    Samir

      Post 74 has the parts list for the transistors.And post 83 shows the schematic
      Whatever I do, I consider it a success, if in the end I am breathing, seeing, feeling and hearing!

            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...

            Denon AVR 1908, High pitch noise on Surround back Left channel after long overhaul
            by karatzdi
            Hello,

            I know some might say... just buy another one. Sell it as parts..!

            So had this AMP for quite some time. Recently I saw light smoke coming out of the AMP. Had my fire extinguisher close by. Just kidding. Turned immediately all devices off from mains.
            Let things cool a bit, and opened up the amp device. I clearly saw on the main board which hosts the 5X amp (5.1), 3 10 ohms 1W resistors had their leads looking black, while the rest of the remaining 2 x 10 ohms were brownish as being installed from factory.

            Spent some time downloading the Service...

            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...
