    TECO TL3291RW. No 12v/24v on PSU (fsp228_3f01)

    Hi, I'm hoping for a bit of guidance again. I'm getting 5v standby but no 12v or 24v.

    I've checked Vs and out on IC1 and read 0v on both. Looking at the schematic I can't understand where Vs is coming from and what I should be checking next.

    Any help is appreciated, Thanks.

    that diagram was drawn up by a fucking monkey, it's almost impossible to follow!

    start by checking the 2 fets driving t1 for shorts.
    and change any electrolytics with a value lower than 100uf

      Vizio E701i-A3 backlight only and now no backlight

      Hello all,
      I’ve tried to repair TVs in the past with some luck. Toms repair manuals got taken down and now thats a bit harder.
      I picked this TV up hoping for a quick fix. When the TV would power on, only the backlights would come on. The owner told me they heard loud screeching before it shut off. This alone makes me want to think the main board has an issue.
      As I researched, I found the TCON/driver boards were an issue on this unit. I went in troubleshooting the TCON but found good voltages on the TCON. I followed shop jimmys guide to test the transistors and they seem okay....

      Wine Enthusiast 170 Bottle N'Finity Wine Cellar Model # 273 02 70
      by magik20
      Hi everyone,

      I'm hoping someone might be able to offer some guidance on repairing a Wine Enthusiast N'finity 170 bottle wine cellar, model 273 02 70.

      I recently acquired this unit for free via Facebook Marketplace, hoping to fix it up as a gift for my wife. I have some basic electronic skills (comfortable with a multimeter, basic soldering, identifying components) but I'm definitely not an advanced technician.

      The main challenge is that when I picked up the unit, the main control/power board had already been removed and the previous owner said it needs a...

      Seeking Guidance on Motherboard Diagnostics

      Hello everyone!

      I hope this is the correct place to post this, if not please let me know and I will post in the appropriate location.

      I'm venturing into the intricate world of board repair within electronics, and I'm reaching out to this community for some guidance and shared wisdom. I have tried to do some research myself and find this information on my own, but I don't know what I don't know, and that is really starting to become an insurmountable issue that I cannot overcome. The only person I had nearby that I could turn to passed away recently so I do not have anyone...

      Acer Alienware Nitro 5 (GH51G LA-L181P Rev: 1C) & Dell Alienware M15 (GDP50 LA-k452P Rev:1) - Both Shorted PCH (SRKMA)!
      by reessi
      Hello:

      I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


      I started on the ACER:

      Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
      All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

      I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...
