Sony KV27EXR20 sound no picture
 

I have a Sony KV27EXR20 and am experiencing sound without picture.
Picture was briefly intermittent then went blank. On power up I get
the degauss. Even though the picture is
dark. I can feel static on the screen and when I shut down, it
collapses to a visible vertical white line and fades away. One email
response said the CRT is gone.
Your help is appreciated.
