The headphone jack on the shelf system is for connecting headphones. It is not an input for sound from an iPad or other source. Buy a lead with headphone jack to red and white RCA/phono. Jack goes to iPad. Red and white goes to Game Port Audio in (bottom edge of unit). Select the GAME input. Play your music.

Hi the reson is your stereo needs to be on groove mode to get max power out of your system

Radio Shack has anadapter catalog number 278-0291. It takes some effort to push the 278-0291adapter onto the FM UNBL 75 ohm terminal so wait until you have the 278-0291installed before you connect your 75 ohm coax on to your new adapter.This will resolve your FM screw on F connector antenna interface issue.I see others trying tohelp suggest using a 300 ohm to 75 ohm transformer match unit, this isn't what is needed. Your receiver antenna input IS a 75ohm input.

This usually indicates faulty wiring, or miswiring. Disconnect the wires, one set and turn the unit off and on to see if that elimates your problem. If it does, the wiring or component is at fault. If you disconnect everything and have the same problem, it's an internal fault with the unit and will have to be troubleshot. Get and estimate first, to evaluate whether or not it's economical to keep, or replace with a new one. Good luck, hope this helps.

Seek professional help.
The lasers are not as expensive as they used to be, get an estimate.

There are bad solder connections on the printed circuit board where the audio output ic;s are located, or some of the interconnecting plugs may need to be reseated.

take out any extra speakers unplug and replug,and if problem continues your fuse is broken.
