Akai 42" Plasma, no picture

[mbates14]

I have a 47" Sony bravia LCD I cant figure out whats wrong with it. it seems to have 2 large heatsinks on the t-con board.

first turn it on, picture is doubled/flashes/ghosts and appears to be missing odd scan lines.

as it warms up, the better it gets and it gets perfect. slowly though its taking longer and longer before it gets better.
