Wont come out of stanby mode ??

Only thing you can do is look to see if there are any fuses you can replace. One other thought is did you test the wires from unit to speakers? A little mouse could have nibbled through them!

We regret to inform you this model did not include Blu-ray player codes for LG players.

an f61 error occurs on a Panasonic home theater system when the speaker cable wire connections are wrong. This situation is likely to happen if you just purchased your unit or moved the system and try to reconnect the speakers again. Polarity is key in a successful setup. The positive and negative ends of the cable wires must match the input of the main unit. Retrace your speaker wire connections to clear error F61 I think it's for helpful for you.

Have you looked at the manual?

Believe it or not there is a seller on eBay who offers a one-price fixit solution for your unit for $100.

That aside, these types of systems are designed as a package to be used as a unit. Otherwise they might have standard connectors. Another closely-related Panasonic SA-HT system might work for you but I doubt anyone manufactures anyhting to adapt non-standard speakers to standard electronics.

They actually say on page 9 of the manual:

"Use only supplied speakers
Using other speakers can damage the unit, and sound quality will
be negatively affected.

I would interpret that to mean 'use these speakers only with similar Panasonic electronics'.

try use dvr/vcr 1 video input and dvr drgitl optrcal 2

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.

It is most definitely okay.

Hi...
The 4 wires are 2 for the treble/midrange 2 for the bass.
You can tie the wires in parallel ( one wire from one pair to another in the other pair and repeat) but you need to know how many "ohms" the stereo can handle.
Should say on the back of the rack system

From the manual, you may have seen this: Switch off the unit, determine and correct the cause, then switch the unit on. Causes include: ?Shorting (bare wires touching) of positive and negative speaker wires. ?Using speakers with an impedance lower than that rated for this unit. ?Straining of the speakers through excessive volume or power. ?Using the unit in a hot environment without proper ventilation.
