Nonsense. FM is included in MOST tv cable subscriptions- make sure your subscription includes this service. Do you have another receiver/tuner to test with? Check all the connections between the cable entrance and your tuner; eliminate all splitters for testing. If you can get another tuner to work on your cable, it may be time to check into your tuner- There is no difference in signal level between tv and fm- your receiver is not gonna burn up! If it has a 75-ohm cable input, use it!

Usually, a hard reset can be done by unplugging the AC cord from the AC wall socket, and re-plug it back after 15 minutes or so. This is true for most electronic devices. If you wish to make a system reset, you should enter its service mode option, and is really a semi-skilled work. If you wish to get some details; check the site linked here.

try my tip: http://www.fixya.com/support/r3554406-testing_your_remote_controller you will know if it's defective or just a matter of configuration...

The volume control shaft lube, over time and heat exposure, will flow down and corrupt the contact between the volume twister and the spring loaded sensor. Pull the cover off the tuner, locate the volume control and take out the two screws holding it in. It looks like a small circuit board with the volume twister attached.
The base of the twister is hooked to the circuit panel by four metal tabs. Pry these guys gently away and pull the twister free. There will be a metal disk at the end of the volume control shaft, and will have a goopy lube residue on the face of it that can be cleaned with electric contact cleaner or some other kind of solvent. Wipe it clean,(do not immerse) reattach, and test. Worked perfect for me.
Good Luck,

Try holding down the advanced surround button and power button. If the unit locked itself into protect, this should clear it.

Run HDMI from FIOS to TV directly, then run Digital coaxial or optical to the cbl/sat audio input of your receiver. That's it. If you have any more questions, just post a comment and I can help more.

Its over heating no cheap fix. But wait if u buy an eternal fan n place it on top or behind it will do the trick. Try blowing on top when static happens n sound comes back on.

It is possible that you have switched it from a surround mode to stereo mode. Instructions on how to select a sound mode begin on page 36 of the manual, which can be viewed at the link below.http://ec1.images-amazon.com/media/i3d/01/A/man-migrate/MANUAL000033275.pdf

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for intermittent shutdown.
