Thankyou very much for your reply,

I had almost given up on this set. I will find the details you require and post back to you.

From memory the power supply is a PWB1420 REV F and in the LG plasma training manual its shown as the Korean version.

Will take the set apart in the morning and try and find the other details you require, thanks again for your help.
