They can be acquired for low cost here in Europe (10 to 15 Euros for a used in good working condition machine). Never tried to open them. But in these machine generations, usually the lcd uses a cheap unreliable flat cable built from plastic where composite conductive material is deposited to make the trace wires. This kind of conductive material will brake with aging. I have fixed other models by simply applying hot air over the flat cable. I just use a regular air drier as the tool. I have posted here before this technique applied on a Casio but can't find the message. Jose Mesquita RadioMuseum.org member |
