LCD Display for W&G SPM-31
Hello Forum
The LCD on the W&G SPM-31, the 10kHz digit fades after several minutes, the part no is a LED 930-080-S-RF-P2H. Can-not find any information on the Internet for this part number, does any-one have any info, perhaps an alternative please. 73's Mike G4WYZ |

Hi Mike,
Can not help with a replacement LCD, but from the schematics it looks like that the display can simply be "recreated" with 7-segment LED displays. Regards, Peter |

Re: LCD Display for W&G SPM-31
Mike: are you sure it's not the drive to the segment? You can check the waveforms going to a "good" segment and compare. I thinkg there's a plug-socket connection in the drive chain? Worth checking that also.
NB I have one of these as well. |
