Hitachi plasma intermittent ghosting

Hitachi plasma 42PD4200

I've got an intermittent picture fault. Full sharp colour picture goes to blur and ghosting for 5 seconds and then back to full colour.

I thought it was LVDS board but swopped and no difference made.

VA & VS voltages spot on.

Any ideas would be welcome.

Check or change SMD electrolit capacitors on Y-SUS board C-18,C-36,C-72 all 33uF/25V

Cornboats:
Many thanks for replying. I check out over the weekend and let you know.

I've a lot to learn- What made you suspect these?

Cornboats:
I've checked all 3.

they are 33mf, 28mf, 102mf.

are these electrolytic?

my esr meter doesn'tseem to work on them.

Cornboats:
I checked the 15V rail and its only 117.-11.9V. I was told it came from the Y-sus board but not sure where to look.

Any ideas anyone?
