I have a panasonic sa-ak630 and it works and everything i just dont have any sound at all

IF the lcd display is fading, the only thing that you can do is send it in to be serviced.

However it is ideal to search around the repair stores in your area to find one if you are lucky.
For new set log on to the Panasonic website.

some time problem with settings restore it. or problem with amplifier

Internal power regulator have failed. Contact any service technician. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

F61 is the shorthand for Panasonic machines to mean protect mode. See the link below for a generic explanation of protector. Specifically, in your machine, either the regulator IC has failed or the output amp IC has failed. In any case, the repair will not be cheap. The output IC costs between $75-$125 depending upon the specific IC.

If you go to www.encompass.com you should be able to find the part you need. I could not identify it but they have just about all the parts in the unit. If you can't identify the part, encompass has a research group. Send them an email with the part description and model number of your machine and they will get back to you with the proper part number. Let me know if you need anymore help.

Set the time via the remote control and this will stop the demo running every time you turn it off.

there is a button on the left side that says "-demo" on it. hold that button until it stops...
