My e470 main speaker on the front speake does not work. Ive checked the wiring and memenbrane al all is in order. Does it mean the speake \r is blown. Can I have it repaired or buy a new speaker if so where?

Does your 12 volt remain at 12 after it shuts off or does it drop to 0?..This model was known for issues with the LED lamps themselves but Ive seen a number of sets where the LED's were fine and it was the power supply or main boards bad

sounds like an internal connection problem. open access panel and check the solder connection is not broken or loose. Be sure the metal mesh jacket is not touching the lead wire as that would cause a scratchy noise and feedback, or maybe near the internal cable causing feedback

you may have blown the one of the fuses in your car look in the fuse box and check the fuse for the clock ps if you find out what wires are what please let me know as ive got the same problem in my fiesta. cheers kez

if the sattelite speaker drops several times. i thing the filter of the speker are broken or the magnet of the speaker are separated from its coil. thats why they dont work... that mean you must replace a new sattelite speaker

The speaker protection circuit sounds to be engaged. This protects you speakers form damage if a fault condition occurs inside the amp. Generally speaking, unless you have good experience at fault finding electronics, then this may be a job for a repair guy. If you want to know more about diagnosing the problem, get back to me here. Good luck :)

Select different modes on the remote or front panel and make sure all speaker that you have hooked up are showing on display. Are the Lt & Rt channels at least playing audio? If you want, i can step you thur some steps to try in live chat if you want today. Let me know as i have experience in this area! Sincerely Guru Jay

Er so you plug the speakers into anther system and they work? Blindingly obvious but there is no fault with the speakers.

The center channel amplifier in the main unit isn't working. Check the warranty. If it's still in force Yamaha will fix it free. If out of warranty, they'll give you an estimate.

ok I thought I anwered this one but first thing to try is disconnect all your speakers and see if the light goes out if it doesnt then your gonna need a schematic and a working know how on solid state amplifiers. first check al the outputs for the speakers for dc If theres dc on an output then that output device is shorted or leaky. Ive have open drivers as well as current control transistors leaky or shorted to that made the protection come on.. Good Luck
