Its a know fault with these sets - PDU's fail all time, look at avforums.co.uk

I have had some issues with high ESR readings in the capacitors in the scaler circuits in those units. Do you have an ESR meter to check the caps in circuit?

If the set is still in warranty, call for warranty service. If not and you feel comfortable working on the set, carefully open up the back and reseat all of hte cables and connectors. This can be caused by marginal connections inside the set.
Keep us posted on your progress and results.

Had the same problem. Was quoted $800 to fix. Searched the internet for 6 months and found this thread on avforums.com

Read through all the posts. Very simple fix, but you have to have some mechanical inclinations or you can cause more problems than you started with. I was up to 5 of the black lines, but decided to attempt the soldering these guys did and fixed it all for the cost of a soldering iron! Even if you decide not to attempt it, it gives you somewhere to start to tell a technician.
