Loewe Calida TV has a red, cloud shaped shadow on the top right hand side on blue background and gold colour on a red background. the TV is 7 years old and been moved three times. It has never been dropped. I have been told it may need to sort of magnetic wand application. If yes can you tell me exactly what this is and who can supply this service

you are going to need an optical assy (A-1084-658-A) and it runs about $1257.50

It could be as simple as dust contamination in the LE or lcd chip. You need a clean room to work on this area of the unit and NOTHING you can do there would make that possible, short of spending a few thousand to build one. Before we added a clean room enviroment we simply pulled the LE and sent it in to PTS - who has one and reinstalled...
In your case take it to a qualified shop and you'll save yourself a lot of grief..

Blue lcd is burnt up.. Normally happens due to excess heat from poor ventilation or not changing the lamp at the required time.. Allways happens on the blue as blue light is the hottest wave length, and as the lamp burns, it shifts to that side. Nothing you can do but replace the lcd itself. From the image shown, looks like the unit uses sony lcds.. Sonys are well known for there burns.. No quick fix on this one.

convergence ic's are your culprit. they are responsible for aligning the 3 colors your tv projects onto your screen..

It sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel... replacing a new colour wheel will solve ur problem
