My company built a machine for a customer using the T35 display (plugged into an original FEZ Spider Mainboard). The display that they are using (we believe) has failed, and only displays a white screen.
If they purchase a TE35 display and directly swap it into the machine, will there be any issues?
They are located far away from us and we are not able to make any code updates to the machine.
If they cannot just “drop-in” a TE35 display, where can old T35 displays be purchased?
I don’t think the displays are “exact” drop-in replacements, although I can’t confirm that. The screen initialisation is possibly different.
White screen is usually seen along with firmware update issues - is it possible the app has lost the screen configuration ? Can they re-flash the board at all ? Do they know if the app is running correctly otherwise?
They have confirmed that the rest of the app is running normally, they are just unable to see the user interface. The machine has several buttons, lights, audio indicators, etc. which activate at various times, and all of them are activating as normal.
They cannot reflash the board (easily). But might be able to be done if the TE35 doesn’t exactly swap in. By “Screen Initialization” do you mean that there may have to be changes to the code before the TE35 will operate?
Could the app have lost its screen configuration due to memory loss? (is this the kind of “lost” you’re referring to?)
I don’t have a T35 or I’d just offer to sell it to you for the cost of a TE35 replacement. I’d bet there are others here that do have a T35 that would be willing to do the same. I can definitely understand wanting to give your client a drop-in replacement and not have them worry with updating the firmware. Good luck!
Cool, I’m not familiar with screen-refresh parameters etc. I’ll have to look up what “backporch” means, haha. Because the screen is so cheap, we will probably just have the customer drop in a TE35 and go from there. Then support remotely if needed. Thanks all, again, for the help. I will report back to this thread to let you guys know if the TE35 drop-in works as desired.
Good news. The customer ordered a TE35, dropped it in, and the display/touch functionality worked normally. I believe that for all normal circumstances/parameters, the TE35 is a literal drop-in replacement for the T35.
