fender frontman 15r

Hello everyone, I just recently bought a brand new fender frontman 15r amp but it started to get this annoying hum out of nowhere.
So i tried to fix the amp for the first time and decided to open it up and take a look but everything seemed to be in order. When i put it back together, you could barely hear the gtr so i am now stomped about whats wrong with the amp.

If anyone can help, it wud be much appreciated...

Is it possible that you have the speaker plugged into the wrong output jack?
The schematic shows an internal & an external speaker jack.
You must use at least the internal jack.
As to the hum, it sounds like a lousy solder job from the factory.

i dun think so cuz i didnt rewire anything. Unless it came that way... If u have a schematic of this model it wud be great help though cuz ive been looking and i only found a .pdf and its taking forever to download.
Also, the hum didnt start rite away when i first turned it on. took about a month after use for it to start thx for the comment

It is brand new, it has a warranty. That is what warranties are for. Take it in for warranty replacement.
