Help diagnosing Motorola Quasar/WU821FS

Hello Guys,

Great forum here! I just picked up this old Motorola Quasar model # WU821FS

The audio comes through great, but the picture is nothing but snow, and occationally a black bar on the bottom warbles it's way through with a thin green line above.

I'm really a novice with old tv's(this is my first purchase, got it cheap). I'm wondering if you all could get some sort of feel of what the issue might be by taking a look at the pic w/ the set turned on.

Thanks to Dave at JustRadios, I was directed to a schematic over at Sam's. I'll be getting one of these for any future servicing needs.

It appears that the last time this television was serviced was 1982 w/ a 2 year picture tube warranty. I am the 3rd owner, but the 2nd owner received it after moving into the house (1st owner left it there), and had it stored away from the get go.

Thanks for any help!
