Do you have set-top-box or antenna-cable directly to TV?
You have connected TV with received via HDMI, but that won't work in this direction - TV has HDMI INput only, not output.
You can use HDMI to connect HDMI-out on DVD player for example to HDMI-in on receiver and HDMI-out of receiver to HDMI-in on TV.
But to get sound from TV to the receiver, use spdif optical or coax cable if TV supports that - this way you will get surround sound.
But also your connection via analog white/red RCA plugs should work, but only for stereo sound.

we bought a flat screen tv and now surround sound does not work with tv but will work with the radio on surround sound What is w
rong

in your dvd player remote there will be sound options in that you can change the sound modes like(jazz,rock,music,.....etc) by changing u can get more sound. If still u are not getting if the two wires of the speakers are touched each other sound will be low check it and u r problem will be solved

Are you connecting from your DVD player to receiver using an optical cable or simple AV cable?

Das TV make cracking and poping noise when you unhook it from receiver?

It must be about the sound quality need of your amplifier. The sound processor simply needs to get clear signals from sources such as fm/am receiver, dvd/cd players etc. in order to manage'em to give you the optimum surround sound. If the fm receiver has an "FM MUTE" option, I recommend that you turn it on. By doing so, you'll receive only good quality fm stations, furthermore your amplifier will let you get surround sound. The second issue you mentioned has its own answer inside. Use a "new" cd player, you can get optical cables, digital coax cables to improve the performance if you like..
