We have a 04 Hyundai-Kia Superturn 10 with Fanuc Oi-TB control. Had the power go out the other day when running it and when everything came back on started machine up and everything was good for about 10 minutes. The screen had nothing but lines on it so figured the screen went bad. Ordered a replacement LCD screen for it and installed. Everything came on and worked for about 10 minutes again then just a blank screen. IF you turn machine off and wait it will come back on but go blank again like something is getting warm then messing up.

When looking on Internet we found some info that said to be sure to change a parameter to color instead of b/w I guess for it to work but I don't know where that parameter is and what to set for it. I've looked in the books that came with the machine and can't find anything showing the parameter settings. Downloaded the Fanuc TB Lathe Control manual and can't find it there either. Anyone know here it is and what to set it to? Also I'm not sure that will fix it as it seems like a board going bad or something with it working for about 10 minutes then going blank.

I haven't contacted Fanuc yet as I am hoping to figure this out. I'm not really electronically savvy on the boards and stuff but any information would be greatly appreciated Thanks!

Looks like an issue that could involve a few potential culprits,
like a failing board or something thermal-related.
When the display works for a few minutes and then goes blank,
that definitely points toward something potentially overheating or a loose connection somewhere.

I want to ask the stupid question...have you checked parameter 3123 screen saver activation time? I'm guessing yes but need to ask ;-)

Best regards,

I have not. But I don'[t have a book that shows what parameters do what and which options there are for them. I will check it though . Thanks! If it is a screensaver thing how would I get it to like turn the screen back on when it goes blank? Just pushing a button or something? Now to add to this once the screen goes blank the program will continue to run .

That is kind of my thinking also but wanted others opinions as well. If it is a board which one would it be do you know? I'll try to go through the manual and see if it tells .. Thanks!

Yes, pushing one of the function keys under the screen or the right left arrow keys should revive it if it is just the screen saver. Change the 3123 parameter to 20 minutes and see if it reacts differently. Yes, you will need to turn on PWE and do from MDI mode.

An update. I called local Fanuc reps and their tech guy said it was probably the cable going from Main box to screen. We did a continuity test on it and all was good. He also said if it wasn't that to try and take the video board out and clean connections then reinstall. Did that and still nothing. Before that it had gotten to where it wouldn't even come on for a few minutes, just light up and say not support.. It does have a video card in it for a CRT screen according to the list Fanuc supplied but the screen we got is supposed to be compatible with that. Of course if the screen doesn't come up I can't get the hydraulics to turn on either so maybe something besides video card? I know when it would come up for a few minutes then go out it would still run program even without the screen. I emailed their tech late yesterday and am waiting to hear back from them. Also would anyone happen to have a copy of the parameters for this machine? We were just getting things set up on it when this happened and never got a the change to download them. Thanks for all your help!

I have an operating 2004 SKT21LMS with an OiTb control. Tell me how to download the parameters and I will make a file and send.
