As the subject said, when i was removing my amp from my car, the input jacks for sound broke off inside the amp input, i dont know how to get it out as the white and red holes are too small to fit pliers in, when i took it apart, the computer board was glued down so i couldnt reach anything. any ideas?

Re: broke ******** in amp input
If the center conductor of the RCA plug broke of inside the RCA jack of the amplifier, you may be able to push it out from the back. If that's not possible, you may have to remove the jack from the board, disassemble it and then push the center conductor out. If you send me a photo of the jack, I may be able to offer more suggestions.

You didn't say whether the player is connected by 2 RCA cables (analog) or by digital cable. If by RCA, does the player have a headphone jack? I had a player once with a piece of a headphone that broke off inside the jack, muting the analog outputs.
No way to do that unless you can figure out a way to remove the part. The contacts inside that plug determine where the sound goes. No way to turn it off unless you remove the broken part. If you feel confident enough, remove the back of the TV and remove the broken piece from the jack.
One can overtighten the input jack and "un-rivet" the jack. They are not made very well !!! OFTEN when they appear loose, they HAVE un-riveted the threaded sleeve from the metal inside the jack... that USUALLY requires REPLACEMENT of the jack itself.
The cabinet backs on a lot of these have to be PRIED out as the Tolex covering often makes them tight.
The amp portion is often retained by screws from the top and or sides AND even the two holding the handle on... there are many different configurations. Sometimes the amp comes out the front, sometimes the back. It is easy to shear off the speaker wires when removing some of them.
I'm pretty sure t6hat the output jack is a sealed unit(contacts inside soldered to the surface of the circuit board. You may be able to grasp the center shaft of the plug with a thin jawed hemostat or really skinny long nosed pliers and pull it out that way. Make sure the amp is off and unplugged from the wall. If that doesn't work you will either have to get it removed at a shop or disassemble the amp to remove the circuit board and unsolder the jack and replace it or get the broken plug out of the jack once it is unsoldered. I've never had a Line6 apart yet but thats probably the type of jack they used. Thats because it has to be electronically isolated from the chassis. Hope this helps.
You might be able to fix it yourself. Input jacks vary some you can use a pin or straighted paper clip to push the broken cable out. Remove the screws on the back (you my need to disconnect the speaker). If the jack is accessible (some are sealed ) using the clip or pin try to push it out from the back side of the jack.
If that doesn't work you are looking at about $50 to $70 replace the jack.
The safest way to fix this is to take the amp apart to get at the jack. If the jack is a solid black plastic shape, then you should replace the jack completely. Otherwise you should have access from the side of the jack to remove the piece of hte plug that broke off.
Hum can come from all sorts of places in an audio amp system......
The shielding on the input cables may be broken.
An earth somewhere can be broken....which then allows "ground loops" to form and unbalances the earthing...causing HUM....
Your note about reducing the controls to zero and the hum is still there leads me to believe that the power filter capacitors or some other filter capacitor in the DC supplies have dried out.
Capacitors can also go "open" which can cause low level sound and HUM.
The motto is "Capacitors get "old" and cause hums"....
It looks like its time for a full service....the amp has done you very well over the years and its like anything else needs a service now and then to maintian the quality of sound expected...If there is one capacitor showing you its getting "HUMMY" then there will be others in there as well needing replacement....
High heat can kill an amplifier so while its getting a check over there will be checks for other problems in there as well..Hot running resistors which can dry out adjacent Capacitors...
