Question about Panasonic SC-HT500 System
Panasonic SA-HT500 system is always in stand by position both disk player and subwoofer lights are red. Any hint?
Hi and welcome to Fixya.
This may sound foolish but just do it... Check the wall outlet to make sure that there is a good connection for the power cord. Unplug / Replug in the cord. I would go so far as to recommend using an extension wire cord for troubleshooting to see if just by using a different power source from a different circuit breaker that the unit performs normally.
If the sleep function has been activated it will automatically go into standby. Press the sleep button on the remote and cycle through 30, 60, 90 and 120 until OFF is displayed. (I would think by now 120 minutes should have passed and this was not the problem)
Usually when a system goes into the stanby mode it has recently been powered "on" either from the user plugging the unit into thewall outlet or after a power loss. Depressing the power button on the remote SHOULD bring the Home theater system out of the stand by mode unless the batteries are low in the remote or the remote is not functioning correctly. (Try the AV button also)
If the remote does NOT function... First off check remove the batteries and check the terminal contacts for any form of corrosion. (Use a DRY 3M "scotch brite" pad to clean corroded contacts if they are corroded and make sure to remove any cleaning pad debris after cleaning)
Remote controls can be fussy when foreign matter gets under the rubber keypad feed on the carbon faced surfaces. Most of the time the remote just stops working all together. The only way to get it to work again is have the remote controls contact surfaces cleaned. Requires dis-assembly and cleaning.
Aditionally if the remote was at sometime dropped the batteries can come lose in their mounts.
The printed circuit card can crack and tear a mini-electrical conduit ribbon.
The Remotes' on board "IC chip" or terminals can crack loosening a contact to the chip.
Lastly there is at least one Capacitor inside the remote that the 2 electrical contact pins can fail from the remote being dropped or falling on the floor.
At this point all things point to the remote...
There is the possibility Amplifiers on board IR recieving circuit has a problem but that is very rare.
If you need more assistance just repspond here. Thanks again for using Fixya! Kelly
