How to repair the pioneer receiver after plugging to higher receiver
edwin_teope68 this could be as simple as a blown fuse or a couple of bad capacitors/ diodes etc. The first thing you want to do is to open it up. Your amp has a separate standby assembly just before the transformer that the power cord connects to. Check on that for any damaged components, traces etc. Post some good pictures of your boards with your question. That way we can see what you see. Adding images to an existing question
If all that was done was to plug the unit into the 220V line, then there is a good chance that the damage is limited to the standby circuit. As stated before, please post some pictures of the unit. Follow the power cord into the unit and try to get photos of both sides of the board that has a small transformer on it. That will be the standby supply. Dan
I fear you have done major damage by plugging it into 220. You need to take it to a repair shop to get it repaired.
dont over complicate things. Step 1 is to check if the fuse is faulty. change the fuse if it is still not working try to go to a repair centre. Check cost effectiveness of repair
