Hitachi picture cuts out

I have a hitachi CT4532 45" projection screen TV.
And the problem is the set will work for a short period of time once
turned on but will soon lose picture. The sound is still playing, I
can change channels but no picture. One I changed the channel
immediatly when this happened and the picture came back for a few
secs. Otherwise I have to turn it off and wait for about 15 mins
before a picture will display again(then dissapear after a while). I
replaced the horizontal sync transistor a few months back. But that
had different problems when it was broken. Just blew the fuse and then
nothing.

Any one have an idea where to start on this ?

Additional questions would the service manual be worth purchasing ?
And if I cannot fix this on my own any estimate on how much it will
cost ?
