    Good beginner repair projects?

    Hello!
    I learned a lot the last weeks about repairing and how power supplies are structured. Fixed two TVs (even though it wasnt really hard since one was a backlight and the other a ribbon tape trick fix).
    Let's say I got a basis of knowledge from where I can start to repair easy projects.

    Looking on local online markets, there are sometimes faulty devices for free. But where to start?

    I try to stay away from notebooks and mobile devices. I don't believe I got the experience, even though it feels like I could do something, after watching hours of notebook repair videos.
    I also try to stay away from TVs, because they are big and I already have two laying around and the faults are oftentimes very tricky to find or cannot be fixed do to panel/tcon/panel stripe boards faults. But it is fun.

    I thought about audio devices like receivers, but they are pretty rare and a lot of times it is just the CD tray that is not working.

    What do you guys think would be a good device to start on, maybe with big components and less chips?

    Just depends on what type of device there available and weather or not you want to get your hands dirty and weather or not you are willing burn up a few things along the way but I can guarantee you that if you do your research on Google is going to be your friend if you can find the right type of video and the right person doing the video and how much real experience do they have and weather or not you understand the concept of what the person is trying to convey in the type of repair that they are trying to do

    You can be successful in doing some type of repair this how I learn to repair switching power supplies and Servo drives but one thing I would highly recommend you make for your self especially if you are going to repair switching power supply make sure that you make your self incandescent light bulb tester that is used instead of the fuse that is in there just in case things go horribly wrong especially if you do not know the history of what the issue the person that had the switching power supply

    One you should be aware of is that some switching power supply do not like to have a current limiting device in series on the power supply rail may switch on and off this why you need to have several different wattage lights if can still find them 100 , 200 , 300 watt ones if you can not find the higher wattage bulbs you can always parallel a couple of them or more to get the current limiting that the switching power supply can deal with without blowing up components on the board if there something wrong with a part of the circuit this is the reason why you start with a low wattage light bulb if as bright as it would be if were plugged into an outlet then either it is the wrong wattage light bulb or there is a short circuit in the switching power supply board the first thing you need to check is if the light bulb is as bright as if it were plugged into the outlet does the switching power supply have voltage on the output side of the power supply if so then use a higher wattage bulb and see if stops turning on and off if dose is the voltage output what the data plates says if so then you can try plugging it into the outlet and see if works correctly or not

      you could target sattelite recievers if they are still as popular as when the D-Box and D-Box2 were available.
      most faults are the psu board.
