Panasonic SA-PM30MD is displaying LOCKED when in "Digital-In" sound mode. Sound stops, not sure if this is due to the "Locked message" and if it is how to fix this problem.

If the sub has a volume control, turn it down then turn up the volume on the amp to the very high volume you mentioned. If it still has very low muffled sound, then we know the problem is about the amp.

This may sound like a silly check, but verify that the tape monitor switch is not engaged. What is the quality of the sound when turned up? Is the cound clear or raspy?

Thanks,
Dan

SOURCE: no sound in hdmi mode unlock flashes on display I get sound in cd

Its asking your permission to unlock the setup menu. When you hit setup, and it says "unlock," you have to hit one of the navigation arrows on the remote control. Once you have unlocked the menu, you can assign the audio to that HDMI input.

The only solution you can do is open the unit, maybe the track rail is jam. If ever you open already the unit push the tray outside and push back inside so it will align again. Hope it will helps. Whatever the result feel free to ask.

Thanks for using FIXYA...

First enable the surround sound mode for the selected input and verify that the media playing is recorded in some mode of surround sound.
You can however, acheive surround sound from 2 channel sources with dolby prologic or prologicII sound processing, or other proprietary modes that your receiver might have from the manufacturer.

If the only thing not working is the optical input, it is possible that the optical converter is defective. Without seeing the actual unit and testing the IC, I can't say for sure. If you have test equipment, let me know and we will attempt to track this down.

5CD changer SA-Ak640 will not open disc trays just diplays "CHGR ERR" is locked on disc 5


The loading mechanism has jammed somehow. When powered on, the unit attempts to get to a known position. If that fails, the message you indicate is displayed. The only way to resolve this is to dis-assemble the unit and rebuild the mechainsm. This should NOT be attempted without the service manual. There is a particular way to re-assemble these so that the gearing is correct. There are small gears and levers that need to be aligned properly. Also, there may be a broken lever or gear that needs to be replaced. I have rbuilt a number of these and the parts (if needed) are cheap (<$4 total).

I wold suggest that you bring this to an authorized Panasonic service center.

I have a panasonic SC-PT850 DVD home cinema system, and although it says it is DTS and Dolby 5.1 compatable but it does not give out any sound at all when i play Blueray films or Playstation 3 games which...


Not so much an answer more a shared problem with a slight insight. On the Panasonic manual page 40 http://www.panasonic.ae/EN/Manuals/SC-PT550%20-%20850W.pdf
It states the following: This unit can decode the surround signals received through cable TV box, digital broadcasting or satellite broadcasts. Refer to your equipment’s operating instructions for details. Only Dolby Digital and PCM can be played with this connection.
So it sounds like the SA-PT850 unit will decode DTS from an internal source ie DVD but not from an external source ie ps3 or WDTV which is a shame because I own a WDTV. The solution for me is to convert the dts to ac3 (Dolby digital) which works great. But not sure if this is an option for you.

F61 error


If memory serves me correctly, the F61 message is teh shorthand for protect mode. There is a problem with the output section that is being detected. The unit shuts down to prevent additional damage to either the amp section or the speakers. I'll look up your specific model for more details. In the meantime, check the speaker wires to be sure that they are not frayed and crossed.

Technics surround sound system


Use whatever TV sound output conforms to your receiver's input. If an optical or coaxial digital sound output is available, that is the way to get 5.1 surround sound through the SA-DX1050. But you have to assign the correct input (COAX, OPT1 or OPT2) to the selector (TV, DVD, CD). See pp 12-13 of the operationg instructions for D-Input instructions. If you don't have the manual you can download it at Panasonic.com.

No sound on DVD mode


Make sure when you select DVD mode that it's not set to "6 ch". (The display will say "DVD 6CH") If you are in the 6CH mode, Use the remote to switch out of this mode by hitting the DVD button again. Hope this helps.
