Head-unit Concerns, need HELP!

[j0nbunklah0m]

I have a head-unit that doesn't turn on sometimes. Everything is wired up correctly, and it works "most" of the time, but sometimes it wont turn on. Also it will not play sound through the speakers randomly, and if I turn the lights off and back on then it will work again. Not sure if the headunit itself is messed up or if it could be a relay or technical issue i'm overlooking. Thanks in advance

I;ve got one for sale for $30. Try it out, if the issue still happens, you know it's something else.

Could be a bad connection, incorrectly wired, radio fuse needs to be replaced (restricting power), or radio is defective. If you have already checked all of these, then you need to have a shop diagnose it.
