Hi all!

Yesterday I took apart my console and cleaned all the dirt out of it. After that I tested the console and it worked good. Later when I tested it again, it wasn't working anymore. I only hear a click on the tv when I power it, but no sound and a black screen. I checked the motherboard for damage, but it all looked good. I also did not see bad traces or anything. I cleaned the pins on the motherboard and on the cartridge, but still the same problem.

Can someone help me to solve this problem?

Thanks in advance!
