    Love your videos! I've never put two and two together until this morning; staying home feeling under the weather. I went from watching Retro Renegades video to yours and I'm like wait a minute the background is practically identical down to the can of spray on the shelf 🤣🤯

      Haha yeah we share the same space and work together. Although I don't work on the consoles, I have no clue how to troubleshoot those so I leave those to my tech. I have however had him on the nickstvrepair channel in the past for some repairs if you go back in time.

    Nice job, those smd diodes short out to quite often as well. Great video.

    The vacuum is definitely cool but I see what you mean about it sometimes being finicky and requiring maintenance

      Hey Malek,
      Yeah I left in some of the strugles that I experience because I legit experience this every other time i use it. Okay maybe not every other time but often enough that it's kind of annoying to use. I only really want to bring it out if I have a lot of joints to do like 15-20 joints to desolder, then it makes sence at that point.

    What are you doing to start the board? Jumping 2 pins? I must have watched all of these videos by now. I’m mesmerized lol. Excellent job.

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน +2

      We connect a battery to the ground with the black wire (negative) and the red wire (positive) goes to the PS_ON command line. So we apply 3v to the on command line.

    • @robbo6460
      @robbo6460 หลายเดือนก่อน

      Thank you for that information. I’m officially addicted to your videos lol. I’m working on an RCA surround sound receiver and It has the switch on the front panel. I’ve been trying to figure out how that switch wakes the board for testing?

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน +1

      Glad to hear I helped you form an unhealthy TH-cam addiction haha!
      But seriously thank you for watching the content, I am glad you appreciate it!
      As for the RCA surround sound receiver typically on off switches will either momentarily (the time it takes to press the power button) allow a low voltage (typically 3v) to pass through thus sending a signal to the circuit board to turn on, or in it's resting state it has a 3v line constantly present, and when that voltage momentarily drops below a certain point the circuit board will turn on.
      You can make that voltage drop by temporarily shorting it to ground.
      Hope this helps

    Thx Nick for your excellent repair tips. In selecting a replacement transistor i read we should consider 3 things voltage.. current..Rds ?

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน

      I have not ever taken RDS into consideration. This could be a big mistake on my part, and it's possible I have simply been getting very lucky all these years, but it doesn't seem to ever have been an issue for me. Do you have more information on why RDS is important to consider? And is it better to go higher and not lower or vice versa? Or does it need to be close to the same within a 20% tolerance or something?

    • @BrianG-x4u
      @BrianG-x4u หลายเดือนก่อน

      @@NicksTVRepair A lower Rds means the MOSFET transistor is more power efficient and produces slightly less heat.

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน

      Thank you for sharing this information. I will make sure to keep that in mind for future repairs. Lower RDS = more efficient.
      It's comments like this that help the community! I know I share a lot of information but I love it when you share information back with me because then I get to learn as well so thank you for that!

  • @mehdiahmadi2785
    @mehdiahmadi2785 หลายเดือนก่อน

    Nick, one question? When the input fuse of the TV power board is not burnt, the MOSFET transistors are not short circuit, but there is no output voltage. In your opinion, which part could be the problem?

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน +1

      Could be a shorted diode, or a resistor failed open. Also could be an IC failure. Is this for this exact model power supply?
      We do offer a mail-in repair if you want us to take a look at it.

    Thanks for this video can you please inform how much its cost for such similar problems including parts and labors charge

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน

      Each board is a bit different depending on how much work there is and the value of the repair. If you have this exact power supply, we have a flat rate service which is linked below:
      nickselectronics.com/products/adtvg1950ab2
      If you have a different power supply we don't commonly service, I would recommend you send it in for us to diagnose and we can quote you from there.

    Is there a discord server that you're on by any chance?

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน

      I don't know why but I strugle with discord. I don't really like it, it's to confusing to use.
      Best way to reach me or my team is support@nickstvs.com or to send messages on TH-cam. I don't check them more than once or twice a week though because I don't have enough time but I do usually check them a minimum of once per week.

    Hello, I have a power supply AP-P397AM-1A that has voltages of 12.6 volts and 3.49 volts on the mainboard connector, but there is no voltage on the TCON connector, what could be wrong? Can you help?😊

    • @NicksTVRepair
      @NicksTVRepair  หลายเดือนก่อน

      Unfortunately, there are a lot of reasons for that to happen. I can't really help you unless you send in the board for me to diagnose and fix. PS It's most likely that the mainboard is causing this.
