You can easily load images, videos can only be uploaded if they are on YouTube. If you have the video uploaded to another place you can just put the link in.
Please don't type in all CAPS, it is considered SHOUTING and rude, plus it is harder to read especially with so little punctuation. It all runs into one sentence!
You should have returned it when you realised the CD player didn't work. Your issue now can easily be fixed. It is likely to be damaged capacitors just due to age. Nice little audio system.

Are you using just the speakers (designated DV-200) or the full
Teac DV-C200 DVD Audio/Video Micro System?
You would need the digital optical cable out from the television to a digital optical cable input on the DV-C200 system. Digital is not like a normal signal in the way that analogue AM radio and FM digital radio differ. In fact it is more like DAB radio.
The best thing to do it Google the manual for the television and the speaker system and read the input and output specs.

You can purchase a download copy of the TEAC AG-V8500 Owner's Manual here: https://www.manualscenter.com/manuals/teac/agv8500-owner-manual.html . The first five pages of the manual are displayed on the web site.
I hope this helps. I can not find a free copy of the entire manual online.
