Oh, in that case the one in Toltekradiation's link above is still touchscreen after all, as it has the U2 chip according to the pictures in the product description.

Still looking then for a non-touchscreen TFT!

I think Toltekradiation's link above is OK if you select "No Touchscreen".
They simply use the same pictures for both options.

I just saw your PM, i'll reply in a minute.

Hi Xavier,

you mentioned a couples of posts back on this thread that you have some spare TFTs that you could test and possibly ship one to me. If you still have those, I would be happy to buy one from you.

Thanks,
Phil

Hi Phil,

How is your preenfm3 ? Metal box from van daal ? inserted in headers or soldered directly ? What PCB version ?
I try to gather infos to see if preenfm3 with display problems have some similar features.

PM me your shipping adress and i'll let you know the details.

Hi Xavier,

I wanted to thank you for sending me the replacement TFT display!

I haven’t had the time yet to install it, as I just moved to a new job and home and have been busy with that. But I very much appreciate your attention and help with the TFT display issue!

Thanks a lot!
Phil

Yes I echo Phil's comments- thanks for your support Xavier.

Others who are replacing TFT screens in Van Daal's FM3 builds may want to note that, because of the case design, Van Daal used long leg headers to connect the TFT to the PCB, so the display directly touched the clear plastic cover in the case and held it in place. The replacement TFT screen will probably have short leg headers. Therefore when you put the new TFT in, the TFT display height will not be level with the screen opening in the case, and therefore won't hold the clear plastic screen cover in place in the case.

If you really wanted to you could do some soldering work to put long leg headers on the new TFT screen. I haven't done that, I've just used duct tape around the edge of the clear plastic screen cover inside the case to attach it to the case. The display does sit a little below the plastic screen, but I haven't found that to be a problem.

Unfortunately I still have the same problem... firmware 110, built up by Van Daal.

Hi,

Reasonable prices for the TFT are back on amazon : around 18€.
Search for "2.8" ILI9341" and check the back of the PCB.
I bought several times the "Hailege" brand. It works fine. It has an additional touch layer, so double it will fit in your preenfm3.
