No there are many diffent things. for your set has about 480 viewing lines or resolution where as hdtv has twice that. impossible to match it but you can take a hdtv signal and convert it work on your older set. good luck

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..
