How can I plug my old amp to new TV with no headphone socket?

[roboplops]

I have an old Denon amp with the red and white sockets and a new LG TV with no headphone socket. There's no sound when I connect the red and white into the TV and no optical input for the amp. Please help, I need my bass back! Cheers, Emma
