Re: My power light keeps flashing.

Diagnostically this isn't a signal that the company lists. This therefore must be a short. Bring this in for service and let them know that your device wont power up. I'd say it need a nes switch or power supply. Hope this helps! Thanks!

Standby indicator flashes

When the "Protection" indicator comes up the display panel of my receiver or the On/Standby LED is flashing, does that mean my receiver needs to be repaired?
The "Protection" light comes on when the receiver's current sensing and thermal monitors detect some unusual operating condition that, if left unchecked, might damage the amplifier. This can happen if there's a dead short in a speaker wire or if you're using very low impedance loudspeakers at high volume for an extended length of time. On older model AVRs you may see the word "Protect" on the receiver's display. More current models will indicate a flashing red light on the Standby LED when a Protection circuit trips
n thermal cases, the circuitry will automatically reset after a few minutes of cool down and the Protection indicator will go out and normal operation will resume. If the protection light came on due to a speaker wire short, low impedance condition or a bad speaker, the receiver's power will need to be turned off to reset it. Before turning the power back on, all speaker wire connections should be checked for their integrity at the receiver side and at the speaker side. If the protection light goes on immediately after you turn on the receiver, disconnect the speaker wires at the receiver side and retest. If the receiver's protection light goes off, then there would still seem to be a problem with one channel's speaker wires or speakers. Connecting them one by one and retesting should allow you to find the problem speaker or connection.
If after checking all your connections, the Protection indicator stays lit, you may need to "initialize the microprocessor (see the FAQ on that topic) or take your receiver to an authorized repair center for a diagnostic. The "Initialization of the Microprocessor" or "reset" procedure can be found in your owner's manual on current model AVR product. Please note, this will erase all setup configurations in the system and require the system to be setup again. You may want to mark down the settings before resetting your receiver to aid in the setup process. If you had an installer setup your system, you can contact them for assistance and any associated costs that may apply to setup the receiver again would be the responsibility of the owner.

Instead of resetting rear speakers each time.....

I have found a similar problem with the rear speakers on this unit (needing to be reset each time the unit was turned off), but found a quicker way around it.....with both the main unit off and the rear receiver off: turn on the rear speaker receiver, then the main unit. If the blue light on the rear receiver does not come on, turn off the main unit, and turn it back on again. This has worked for me ~50 times or so and has worked repeatedly. It's faster than going through the reset phase each time. Also when turning off the system, turn off the main unit first, and then the rear receiver. Sometimes I also simply leave the rear receiver on since it pulls only 4 Watts. Hope this helps any users.....(it also works on my boyfriends older generation model).

1 Turn on SE-FX65 2 While pressing [>>/>>'] ] press the numbered button [3] on the remote control until "P" lights in the home theater unit's display The indicator on SE-FX65 turns green. 3 While "P" is displayed, press [I/D SET] 4While pressing [>>/>>'} press the numbered button [3] on the remote control.
This worked for me. I moved and lost the FX65A, and Had to buy a replacement off ebay,

My Panasonic SC-HT995W keeps on flashing W and the rear speakers wont work. Ive tried turning off all other wireless devices but it still persists

I had exactly the same problem. My unit worked fine until a loose power cable resulted in the receiver being turned on and off a couple of times in quick succession and then after this the a/c in light on the rear speaker was lit but the wireless link light would not come on (and the 'W' on the main unit flashed constantly). The solution for me was basically a reboot. This is what I did;
- unplug the wireless receiver
- unplug the main unit
- remove the digital transceiver unit from its slot in the back of the main unit
- plug the main unit back in and turn it on - the 'W' won't flash as the transceiver has been removed (not sure if you if it's necessary but I made sure it was producing sound to the front speakers)
- unplug the main unit again
- reinsert the digital transceiver
- plug the main unit back in, turn it on and set it to produce output/sound (the 'W' will be flashing)
- then plug the wireless receiver back in again
...presto the link is made, the 'W' stops flashing and the rear speakers work again.

Hope this elaborate reboot works as well for you as it did for me.

The screen keeps flashing rear chk and the rear speakers are not making any sound.

I had the very same problem, and found that if you power up the receiver in DVD/CD mode, or tap the function button to display DVD/CB mode, the Wireless Rear Speaker AMP will automatically recognize and turn on the sound. This work around was not posted anywhere in the manual, just 1 of many workarounds I have had to put up with this system to work. Right now my fan went and it just keeps shutting down, I have had this system for about 15 months and very disappointed with the quality. My DVD player stopped working a few months ago, so now the system is rendered useless, not even sure it is worth fixing at this point since it is no longer under warrenty.

Jvc th-s3 won't turn light flashes briefly and then goes out


from my experience, I think your player is having a power problem. It must have received excess voltage/irregular power supply which has damaged an IC or capacitor on the power board of the player.

Sometimes this excess power supply might damage the player's main board. This is why it is advice able that you use step down for your player, because DVD player don't need excess power as something might be damaged.

To solve this problem, you will be needing a meter. Open the player, use the meter to read the components on the power board as it will help you discover the component that got damaged and you can then replace the bad component.

But if you do not have the knowledge of fixing this problem, you might be needing the help of a service technician.

Take care.

Rear Wirelss speaker do not work

With the main unit turned off, press and hold [REMAIN] on the home theater's remote for 4 seconds. (The REMAIN button is directly under the 7 button). Once held down for 4 seconds, the Volume Indicator on the main unit will turn on for 1 second. Release the [REMAIN]. 

Press the [RESET] on the back of the Wireless Receiver 2-3 times. The Standby/On LED on the front of the Wireless Receiver will blink 3 times
Turn on the main unit. The Link LED on the wireless receiver will light up if process is done correctly. The front of the main unit will no longer say REAR CHK and the rear speakers should now function correctly.
