TM172PDG18R PLC screen going blank

[Kunal_ch]

Hi,

I raised a concern regarding the TM172PDG18R PLC screen going blank in the post "TM172PDG18R screen sporadically going blank", where I was told that this is due to some hardware issue in some limited cases (after hardware update was done).

Could you please let us know which batches (MM/YY of manufactured products) should to be investigated to be on the safe side? 

Today we quarantined x3 PLCs which were going blank for a second, every 20 seconds. All of them had serial number "2025W07xxx" (belonging to the same batch).

Any idea of the dates would be greatly helpful.

Thank you.
