2 options comes in my mind...
Put software upgrading CD manually in player and let it finish software upgrade process.
If this trick doesn't work, you need to replace digital process board or need to replace on board ROM, if you can.
let me know if you need further info.

What r the codes for ge universal remote for kirsh home theater system model k3

Set-up (Programming) procedure is too much to type in here, and is not practical and it will differ brand-to-brand remote controls. If you wish to get more; check the sites linked here. The site has set-up code list & set-up procedure to many popular brand remote controls. The site has general set-up codes to check with TVs and other devices are given, in the order of the 'device's brand name list' in alphabetical order. Set-up code list to many brand remote controls also is given. Pull up older posts. Search the sites by type in the brand name to your device in its search box at the top right part of the display window. It will help you to find the document easily.
Programming Notes
• If your device does not respond to the remote after trying all codes listed or your brand is not listed in the code list, use the Auto Code Search method to program your remote.
• Sometimes the first code that "works" with your device may operate only a few functions of your device. There may be another code in the code list that performs more functions. Try other codes from the code list for more functionality.
This is a trial and error procedure; and quiet time consuming. You might have to check different codes said for your device.
Search the site by type in the "brand name" to your device; to which you want set-up codes; in the "Search box at the top right of the display window" to get gathered related posts.

Cd, tuner and all other functions work except the sound.

Where do i find a firmware update for RCA DTV_SLD50ARQ-2015. and how do i install it since it tells me download metadata fail

You must follow the instruction at the RCA website to update the firmware, my advice? If the player is working ok leave it alone, firmware updates if done incorrectly (one small missed step or mistake) can and do render the device being updated useless.

BOSe Wave Radio - Disk "not readable"

I had the same problem with the disk unreadable error and took my unit to a authorized repair dealer about 100 miles from where I live to have it fixed. It ended up costing me about $300 to have the CD unit totally replaced which is almost as much as I paid for the unit in the first place. I am like a lot of you that used the CD very little although the unit was about 3 years old. I think Bose has a problem and would like us to think it is very rare. I bought a Lifestyle surround system about 14 years ago that has a CD and have never had a problem with it so needless to say I am very disappointed in the Wave II Radio/CD system. I am fairly certain the problem will occur again, but only time will tell.
