Replace the batteries in the remote with fresh ones. Take your smartphone and use the front facing selfie camera to to see if you see a flashing red light when you press a button on the remote with the front of the remote facing the phone. If you can the red light, the remote is working.
The speakers have quit working or the wires that connect to the speakers are faulty or there is a source component that is malfunctioning on your stereo that needs to be repaired or replaced.
There's so much information missing from this question, but assuming this is a DVD changer, it's a disc error. Either the disc is upside-down or backwards and can't be read, is too dirty/scratched or unsupported and can't be read, or the entire mechanism is jammed or malfunctioning. If there are discs in the tray and you can remove them all, remove them and see if the error goes away. If the tray will not open, either take the cover off and remove the discs, or bring it to a service center.
I think I have this unit. Did you turn the balance control firmly in both directions fully left to right? If you could get behind it, you could spray it with electrical switch cleaner. If you changed speakers over and you checked the wiring connection on the unit and and on the speaker, then it will be an amplifier stage issue, perhaps a failing capacitor. You can look for that. If not, Sony Service Centre.

Have your device being fully plugged into an outlet that works and turn off and take off any serge protectors and if it is still not working your device might be broken and needs to be repaired or replaced.
Get a CD cleaning disc from Walmart or Amazon. There are two laser optics, tracking and read/write/ It sounds like both of yours are dusty with either causing the issue. The tiny brushes on the disc clean the lasers.
Humming is normally bad shielding or grounding within the plug. Sony are also a strange company and do things _their_ way. Also cable come in different qualities and with good audio equipment buy the best with gold flashed contacts, copper stranded cable and good screening.
Hi,
Please double check that you're using multiple cables from your blu ray and not just one. A coax cable can connect your bluray player to your amp and then another cable from hdmi output can connect to your projector.
If you need more help in figuring out exact cable types and detailed home-theatre setup guide, you can reach out to dolby as well by calling 415-558-0200. They do home theatre setup as well.
Thank you.
Were these discs labeled CD-R Digital Audio? This compact disc recorder can't record to CD-R data disc for computers. See the manual on page 7. The manual is available here: https://www.sony.com/electronics/support/res/manuals/4246/42460761M.pdf .
Apparently, there is a header section on CD-R Digital Audio discs that tells the RCD-W100 that the disc is for audio recording. The work-around would be to process your audio files on a computer and then write the music to the CDs that you currently have.
I wish that I had better news for you.

Hi,
please shutoff your home theatre system for 5 to 10 minutes and double check that you've not plugged any of it's cords into incorrect jacks. You can then power on and check the device's buttons again. Thank you.
