No sound on regular t.v. and dvd, works with radio

Iphone maybe korean ...

unplugg your tuner from the AC wall outlet then check the setting on the tuner do not try to watch and listen to the tv only try to listen to the radio or a CD and select the right option on the tuner to do so. If you have sound on any of the functions....radio or CD/MP3 then the problem lies on the setting not correct for the TV/VCR/DVD mode.

I’m happy to help further over the phone at https://www.6ya.com/expert/josh_87ce33216d7b2148

have you connected the optical cable. as the only way to get sound from the tv to the surround is via that link. the hdmi cable only send video and audio to the tv not both ways for some reason.

dvd format must be compitable with tv-if it is compatible change your video cable with new good brand one from (radio shack)or any electronic store near you.

Check the fuses inside?

when i turn my home theater system on it says f61 then it shuts off can u plz help me out here =[

your sytem is going into protection power regulayor ic needs to be renewed

If you listen to cd's and the sound dos'ent cut out then it cant be the amp. It could be the audio cables are intermittant between the amp and the dvd playerr or they are loose or corroded a little. or ppossible the input your using is going bad on the stereo sytem but I wouldnt think that the whole system was blown if the radio and the cd plays normal.. check out the causes I listed and let us know if you need more assistance\..:)
