My infinity tss-1200 subwoofer was working and then turned off while listening to music then on and then off. The red light is not turning on nor the green. Is it blown or is it something simple?

SOURCE: Red light and thumping sound,

If your talking about the thump thump sound thru the sub when in standby mode, here's a fix if your good with a small soldering iron. Remove the amp from the sub. Locate U301 on the limit curcuit. (the small circuit card standing up right) Replace U301 with a TL074IN (www.alliedelec.com part #248-0012) .35cents +S/H also remove R263 from the preamp board,add a new 1N4148 diode(#935-0242) .05 cents to the pre amp board. Connect the Anode of the new diode to the Anode of D101 and the Cathode of the new diode to the Cathode of D108. Replace amp and test. Thump thump should be gone.

There's a seller on eBay who has a fixed-price repair for it...

which may be cheaper than sourcing the part and getting it installed it yourself.

SOURCE: a low frequency all the time from the subwoofer. Infinity tss-450 (120 vac)

Try hooking the speaker into a different input device if the problem still occurs most likely the built-in amplifier is shot & has a bad capacitor or other component. You can also try remove all RF emoting devices far away from speakers like cell phones, devices with motors like fans, or any other wireless device or least turn them off. Sometimes other devices on the same A/C circuit can cause interference, computers, tvs, etc.

How do I remove the speaker enclosure of a infinity tss 1200 satellite speaker ?


You should be able to remove the front panel of the speaker just by pulling on it. They are typically snap in screens. From there you will see the mounting screws and can take them out one at a time.

Why does Infinity TSS-1200 subwoofer make grinding noise?


If it isn't brand new, it sounds like the voice coil is striking. This can be caused by damage to the suspension system or simply an overheated voice coil inside the sub. No easy fix unless your handy at rebuilding speakers. I would suggest buying a new one or sending back under warranty if it is still within warranty period

Sub will not come on and light is offf on back it as a tss 1200 sub


The first thing to check in this situation would be the status of the internal buss fuse. If that is broken I would recommend replacing it and re-assess the situation.

Infinity tss-1100 sub problem


hey buddy, I have the same system, and although I haven't experienced it on this one, I had the Harman Kardon equivalent to the TSS-750, and the sub did this same thing. It was a loose RCA connection, and, as I was well outside of warranty, I took the amp out of the back and just re-soldered the connection myself. It now functions flawlessly for my bedroom setup. I hope you get it all worked out on your system! I can't imagine using this awesome system without its deep notes!
