Sony Trinitron KV32F300 Power and Sound Issues

Hello, I have a Sony Trinitron, model KV32F300. A couple weeks ago, it would not turn off unless unplugged, and it would not turn on unless plugged in. When plugged in, the volume display bar would appear and steadily raise from low to max and stay on max until the TV was unplugged again...plugging in would restart the process. Remote would not turn set on or off nor affect the volume issue. So, I think it may be something with the set itself. Any thoughts? Thanks.
