The display microprocessor(computer within your unit) may be bad. This IC is responsible for processing any and all IR(infra red) commands from the remote, as well as scanning all the push buttons on the front of the unit. If you're interested in having your unit repair, please visit me website at audioserviceclinic.com. You may contact me there. Thank you.

It sounds that the Closed Caption function [CC}, is not set to ON. Set it OFF. Push the button marked {CC} at the remote control once to get rid of it. If there is no CC button on the remote control, you have to enter its service mode option to deselect it. If you wish to get more details about how to enter, adjust and exit the service mode, check the site linked here.

Hello
Check the cells in the battery compartment of your remote control handset. Replace it with new ones and check. Still you poise this problem, the intensity of infrared rays come from your remote control, or the sensitivity of the infrared sensor inside your bose front panel system may have the trouble. Just replace the infrared LED of your remote control with an other one of same type. If it does not helps you, repalcing the infrared sensor will reftify your problem. OK.

The sub is bad.the power supply inside the sub is your problem.If your unit comes on it could also be a defective dsp pcb in the sub.everything in the sub runs the head unit.If you send to bose they have a 175. flat rate.

I got my bose remote to work when I did a system update on the remote. Turn the TV on. Select the TV video input that connects the system. On the control console, press and hold setup until the system information screen displays. line 5 will display the currently installed console software version. on the remote press any button. Line 10 will display the currently installed remote software version. Do a bose system update. On the control console press setup. on the remote control, press the down arrow until update is highlighted and press ok. make sure yes is highlighed and press ok. on the control console plug a clean usb drive into the usb port.when prompted, remove the usb drive and connect it to a computer. open the drive and double click on the download_launcher file, which should bring you to an update page on bose.com. Once complete, put it back in the control console. When the update is complete remove the usb.

Press Display / " i " Button on TV remote, on-screen display will disappear.

check the voltage setting on the power supply that connects the power cord to the media center. Mine was set to 230V. Changed it to 115V and the video starting working.

Unplug the power cord and plug it rght back in, I had this same problem and was troubleshooting forever.
