Sony Trinitron model KV-35S42 wont turn on?

We have a Trinitron TV Model # KV-35S42 Manf. date 2/02 and suddenly it just wont turn on. When we push the power button on the standby/timer light just flashes. We have tried various troubleshooting techniques and were told to call a TV repair man. My mother and I live on a limited income and have decided that we could almost buy a new TV as cheap or cheaper than to have this one repaired.
