Helloooo, i'm trying to repair this cheap 12v "5A" power supply i was given a while ago and even though i said i was not going to repair it due to how cheap and crummy it was, i was board and so i decided to pull the power supply out of my scrap pile (or what was left of it since i started taking it apart) and put new parts into it. And even after fixing most of it up it still has the same problem as it did before fixing it. The problem appears to be the circuit is pulsing on every second or two almost like it's in short circuit protection mode except there's no reason for it to be at all. The output voltage does rise up to 12v under no load so it does not appear to be shorted.
If anyone knows what's the cause of this problem then i would like to know, thanks.![Biggrin](https://cdn.badcaps-static.com/images/smilies/biggrin.png)
(PS: The main reason i repairing this power supply is so i know how to fix similar issues in future repairs)
