|Pioneer LCD problem or feature!|

I recently got an old 17B II for a song - in good condition except a strange feature in the display.
Firstly, the LCD is dark even when the calc is off and viewing angle is narrow when operating. Slight annoyance.
Secondly, the odd thing is that you can read some text through the LCD. The text is in the top right hand corner of the display, mirrored in relation to the calc and reads: "3-A7088B-DL NOSPE" on the top line and "C374M" just beneath. Neither of these lines obstruct the actual display segments.
Reversing the text gives: "EPSON LD-B8807A-3", "M473C". Presumably, this is the component name for the LCD?
The calc cannot have been opened in the past.
Anyway, the point of me mentioning this is can it be got rid of? I am wondering if the LCD has suffered a bit of high pressure or temp extreme during its life which is why it is dark and this text shows through.
Has anyone come across this before or can offer any advice please?
