I have a Sony 32 inch TV KV32XBR85 with a weird pincushion/horizontal
problem. The picture alternates between two problems states: one where
the top and bottom of the picture are stretched out (like a corset) and
a second where the picture is pinched about an eighth of the distance
from the top & bottom (like an urn). At power on the picture tends to
be in the first state then flickers back & forth between the second
state, eventually settling on the second state. It's a bit hard to
describe so here are actual pics of the screen:

I haven't opened up the set yet. I tried the smack test, without any
effect on the picture. This is a nice TV and definitely worth fixing
IMO. Any tips on what to check, common failure parts or rebuild kits
would be much appreciated. TIA.
