Hoping for some clever advice here. My Tv panel has cracked and hence no longer showing anything useful other than crazy lines! There are a lot of cheap H5000 sets available out there but not so many H5500 sets. Does anyone know if the Tv panel and attached boards are the same in both models? I was hoping to buy a cheap one and swap out my broken one. The H5000 looks like it has slightly bigger case but is the actual tv panel used the same in each?
