Yanmar 3YM30 engine hour display

[yoda]

Like many, my engine hour display has failed so I have no idea how many hours the engine has done. Following searches online I thought changing the LCD screen was the way forward however it appears my tacho is an older variant that does not have a replaceable screen. Does anybody know of any specialist electronics company able to interrogate the unit to find out the hours to date? I don't want to repair it as I now have a separate hour meter but would just like to know for curiosity sake the hours done.

Many Thanks

I have a very early 3YM30 (built 2004) with the older style key panel and the VDO tacho has a replaceable LCD - I have done it with the part from AK Speedo - https://www.akspeedo.com/vdo-yanmar-volvo.php - they also have a video of how to do it.

As above, replaced my 2006 vintage LCD with an AK Speedo part. A straight forward process, just follow the videos and go slowly.

Not sure if this is any use to you. I remembered it coming up on here before and tracked it down.

Unfortunately my tacho is different to these and is not repairable in this manner.
