Sony KV-1311CR TV/monitor video problem

[Phil Nelson]

I bought this Sony KV-1311CR new about 25 years ago and have used it almost daily since then. The photo shows a problem it just developed -- slanting sort of herringbone (?) patterns all over the screen.

Any ideas where to start? I'm familiar with 1940s/1950s TVs, but this kind of new-fangled rig is mysterious to me.

I posted the (4-meg) Sams manual at http://antiqueradio.org/art/temp/2393_2n.pdf .

Thanks!
