nkwai Posted January 8, 2018 Report Share Posted January 8, 2018 Hello, I have a problem with a V130, some horizontal display lines just disappeared (see attached picture). I still haven't tried anything because I thought it would be best to ask here first if someone maybe knows the solution. The only idea I have is to open it (like when adding ports) and clean the contacts. Any help will be appreciated. Regards Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted January 8, 2018 MVP 2023 Report Share Posted January 8, 2018 I would first be checking the ribbon connector insertion. It is very easy to not push it in far enough before reclamping. If cards have been added then it is the likely problem, as you have to undo it for some add-ons. Owing to it being fiddly and awkward it can seem to bottom out, but it isn't in enough. But use care in any manipulations. Undo the case rear and then carefully lift out the "first" pcb by holding the connectors. Check out the install instructions here: https://myzone-kza3sadj.netdna-ssl.com/wp-content/uploads/2015/12/installation-guide-V100-17-RS4X_ET2_S-ET2_17-PB1.pdf They will give you the details about the ribbon, bottom of page 2. Hopefully that will be the issue. Pls advise back. cheers, Aus Quote Link to comment Share on other sites More sharing options...
nkwai Posted January 9, 2018 Author Report Share Posted January 9, 2018 Thank you for your answer. Opened the PLC today, cleaned all the contacts, double checked the ribbon, but the display is still the same. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 10, 2018 MVP 2023 Report Share Posted January 10, 2018 I'm afraid your display driver has gone bad. Unitronics PLCs have a two year warranty - how old is it? Joe T. Quote Link to comment Share on other sites More sharing options...
nkwai Posted January 12, 2018 Author Report Share Posted January 12, 2018 Hi, it's well over warranty, it think it's around 9 years old now. Thankfully there is a PC near, and the PLC is connected to the network, so I using Remote access for now. I'll contact the representative for my country to see if it is possible to repair it, or a replacement is needed. Quote Link to comment Share on other sites More sharing options...
MVP 2023 Joe Tauser Posted January 12, 2018 MVP 2023 Report Share Posted January 12, 2018 No repairs on V130s. Good idea on using Remote Access! Joe T. Quote Link to comment Share on other sites More sharing options...
nkwai Posted February 2, 2018 Author Report Share Posted February 2, 2018 I contacted the importer, and got a new LCD (yes it is possible to replace), now it works again Also after tearing it all apart, seems thet the ribbon cable mentioned above is just for the keyboard, the LCD is connected directli to the main board through the pins you see after removing it.

Bad Ausman! Thanks for letting us all know the good result. cheers, Aus Quote Link to comment Share on other sites More sharing options...
nkwai Posted February 2, 2018 Author Report Share Posted February 2, 2018 For anyone interested, a picture of the back of the two screens (on the front is just the screen). On the top the old one, on the bottom the new one, interesting to see they completely redesigned it. 1 Quote Link to comment Share on other sites More sharing options...
MVP 2023 Ausman Posted February 3, 2018 MVP 2023 Report Share Posted February 3, 2018 The new one is so much simpler, ain't technological progress great? Wish they could upgrade my brain so easily. cheers, Aus Quote Link to comment Share on other sites More sharing options...

How did you manage to access the hmi remotely? i have the same problem and i have a PC but couldn’t establish a connection between the PC and the PLC what cable did you you use? how can i configure the communication settings from the screen if the screen is dead?
