poisenoire Posted March 19, 2019 Share Posted March 19, 2019 Greetings, One of my (3) T3 in-wall 7" recently stopped responding to the top section (C4 icon, back arrow, close) rendering it fairly useless for easy navigation. If I touch the top section it seems to be miscalibrated and highlights the second row section (room selection, etc..). However, every once and a while it will work briefly for one push then reverts back to the incorrect calibration. I have tried factory reset, remounting, complete power down but can't get it to work consistently. Any ideas? All are powered via POE and I'm nowhere near power budget issues. This has been stable for 2.5yrs and just started on a very lightly used panel. The panels with heavy use are doing just fine. Thanks Quote Link to comment Share on other sites More sharing options...
digitaltrader Posted March 20, 2019 Share Posted March 20, 2019 I have 2 units doing the same Quote Link to comment Share on other sites More sharing options...
DLite Posted March 20, 2019 Share Posted March 20, 2019 I have had this problem with two different T3 portable units. Both times I had to get them replaced, as it was determined to be a hardware problem. Quote Link to comment Share on other sites More sharing options...

digitaltrader Posted March 20, 2019 Share Posted March 20, 2019 Mine were 2 months out of warranty....both with touch screen issues yet barely used. Quote Link to comment Share on other sites More sharing options...

Cyknight Posted March 20, 2019 Share Posted March 20, 2019 The T3 Series Touch Screens auto-calibrate during boot up: To calibrate the TT7 & TT10 touch screens, press and hold the button on the top right of the unit until "Do you want to shut down?" appears, then press OK. After power down, press and hold the same button from the prior step to boot the touch screen back up. To calibrate the WALL7 & WALL10 touch screens, press and hold the top button to the right of the reset pinhole until "Do you want to shut down?" appears, then press OK. After power down, press and hold the same button from the prior step to boot the touch screen back up. Quote Link to comment Share on other sites More sharing options...
Cyknight Posted March 20, 2019 Share Posted March 20, 2019 That's the only 'calibration' there is on T3 screens Quote Link to comment Share on other sites More sharing options...
Unsocialtoaster Posted March 21, 2019 Share Posted March 21, 2019 Unfortunately the tabletop screens are quite well known for this very issue The top and bottom bars both seem to stop responding, sometimes one or the other, sometimes both.

This is definitely a mfg issue and should be covered out of warranty. C4 are you listening? Quote Link to comment Share on other sites More sharing options...
Gary Leeds UK Posted March 21, 2019 Share Posted March 21, 2019 Can say no on the listening bit - We just lost one with the same issue which is also out of warranty Dealer says I need to buy a new one - Will give me a good rate. Still should last longer than 3 years Quote Link to comment Share on other sites More sharing options...
poisenoire Posted March 31, 2019 Author Share Posted March 31, 2019 Thanks all - that's what I was afraid of. Doing reset and even remounting did nothing. Very surprised to hear of this failure rate on here. My other units are acting fine so hopefully this is isolated. Like others - this is out of warranty but still only around 3 years. Definitely should last longer than this C4 could at least offer a prorated repair cost option. Quote Link to comment Share on other sites More sharing options...
digitaltrader Posted March 31, 2019 Share Posted March 31, 2019 Maybe we should approach C4 as loyal customers. A little concession on their part would go a long way for their most vocal customers. Quote Link to comment Share on other sites More sharing options...

K Wise Posted April 26, 2020 Share Posted April 26, 2020 I have the same issue. Unit is not yet 4 years old and used 4-5 times a year, maybe. What was the final resolution to this? Is C4 offering any type of assistance? Thanks Quote Link to comment Share on other sites More sharing options...
deeonline Posted October 23, 2021 Share Posted October 23, 2021 I had multiple issues with T3, more with 7" screens than 10", though. It starts with a partial touch loss, then out of calibration issues, then more screen space stops responding. Quote Link to comment Share on other sites More sharing options...
