This is most likely the power supply board. The manual for it is here: http://servicepartsmanuals.com/repair/service-manual-pioneer-sd-582hd5-sd-532hd5-projection-monitor-receiver-2/

internal components probably need to be cleaned.... sounds like a problem with t.v. overheating

Sounds as though the output transistor(s) on the color convergence board are going bad or already have. If handy with Electronics; get service manual and check the emitter voltage.

The problem you are describing is known as a pincushoin problem. I'm a bit surprized that you only see it on the 1080i signal though. I've inquired at my Pioneer contact about this and will update this soon.

Stay tuned...

A microchip controls the color convergence. There is no easy way to fix it. A new chip will be needed.

had the same problem on mine.
Found loose solder terminals on the main power transformer, resoldered fixed it up about 5 min.

Its the Power Supply board

the problem with pioneer projection tvs is that when they made the boards they never used enough solder for the circuits and you get cracks in the runs. thats why heat and cold will effect it. I had the same problem and I took out the board and resoldered every track I could and it works good now but my remote wont work if anyone has any info or prints to this tv please post on here

the clicking noise is probably just the relay. I gyess it makes the same noise if ou turn it off manually with the remote? Does your TV have a sleep timer function? Check to see if this is enabled. You might also check the batteries. If they are old, or the battery compartment is dirty (leaking barteries etc) you might get strange behaviour. My remote lives a life of it's own, changes channels etc if the batteries are weak.
