I have purchased a GMC320+V5 recently and wanted to sell my old GMC-300. I have now noticed that the display starts to fade away on the upper right hand side where the battery symbol is placed.
The LCD is a
Wayeah LCM (2012.05.16) KM12232K.
Where can a get a replacement for a good price?

Best regards,
leescratchwood

Thanks for your help to all of you.
Attached is a picture of the display.
The PCB says KM12232K. As ZLM points out they are rare, indeed.
I am quite sure, that these here are identical:

(have a look at their specification/description)

I have ordered 2 pcs from them. I will comment after receiving the display if my problem really gets solved.

The old GMC-300 used a different LCD module and it is hard to find the replacement.

Hi,

I really don't know the construction of that model, but sometimes there is an elastomeric (flexible) connector between the circuit board and the display. If the pads get a little dirty or corroded on the board or display this could cause symptoms on the display. Remove the connector and clean the pads with a pencil eraser. This has happened many times on my digital test equipment and was solved.

Hope this helps,
--Terry
