I have another CX with a bad LCD that could be a possible donor. Probably with a rework solder station. Blowing hot air might damage other components. A trick I came across recently for desoldering surface mount chips (I think it is on UTube somewhere) uses a Halogen car headlamp. These emit quite a lot of heat and is sufficient to melt the solder. You might be able to mask the plastic part of the chip to protect it a bit. Sunglasses required ;-) cheers Tony |
