The problem i have. Perfect picture top half of screen,the bottom half is complete but two or three bottom halves super imposed on picture.Would appreciate any help on the fault.I am an ex tv engineer of 20 years.Have been out of trade for ten years,this flat screen technology is nothing i have ever encountered.Many thanks for your time. Phil.

It is a guess without doing some testing.   My guess is the main board needs repair or replacing.  It is about 30 pounds to purchase a replacement board - if that were the culprit.

It may be that some wiggling and jiggling would clear up a bad connection of one of the ribbon cables.  Or, if you are brave, disconnect from the mains, remove the back cover and reinsert all the cables, connectors, etc. as one of them may be making poor contacts.
