pioneer sdp6091 blooming problem?	Can't Post

I inherited a pioneer sdp6091 that had a few problems. I have got one problem I just can't get a handle on. It was described to me as a blooming problem most likely caused from high voltage control problem. The left and right sides of screen are collapsed somewhat when first turning set on. After it warms up problem completely disappears from right side though slightly visible on left. Severity of this is directly related to if background is lighter. If backround image is dark it all but disappears.

I have included a picture of what I am trying to describe. I am not a repair tech though have a knowlegable electronic background and tools. Any help will save my sanity.
