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

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

Thanks for your reply, JDL…

And thanks for confirming that swapping out the display is a possible fix for the screen going all white.

I’ll go that route after I check back with Xavier at the end of August.

Thanks,
Phil

Hi Xavier,

if you try your spare TFTs and think they might be a fix to the problem, I’d be happy to buy one!

I’ll contact you at the beginning of September.

Thanks!

Phil

Oops, seems like the person who asked me for an update might have been the one who tried a different display!

So, I guess that didn’t work out after all.

Hi,

after a long time away from my music equipment, I’m just coming back now and am currently using the PreenFM3 remote controlled via the editor software without ever looking at the display of the synth. So I haven’t attempted to fix the display yet.

I just read in another thread on this forum that someone might have successfully fixed their display by installing a different display. The person provided a purchase link for that on Amazon. My impression is that I should just buy that display instead of trying to re-solder the display that came with the PreenFM3 kit.

But I probably won’t deal with that anytime soon and am quite happy using the PreenFM3 through the editor only.

And just to say it again: I love the synth engine and the sounds I’m getting from the PreenFM3!

Yes, that’s true. I forgot that I tested it before with the internal sequencer and also got a blank display.
I just don’t remember ever editing any parameter and the display going blank at the same time. I guess that’s why I thought that changes on the display from editing may not result in a blank display.

I haven't used the USB Jack for MIDI in my setup.

I guess I’m still hopeful that there may be a solution to the blank display other than me having to resolder the TFT.

Thanks for all the attention you have already given this!

Hi Xavier,

sorry it took me a while to report back!

I did some extensive tests with Firmware 105, but the display also blanks out with this firmware.

This time, I used a stop watch to check how frequently the display goes blank. With four MIDI tracks playing four voices in the PreenFM3 the display went blank far more frequently than with just one MIDI track.

I remain a little skeptical about the TFT connectors causing this. But I will, at some point, resolder the TFT in the hope that it solves the problem.

I could be wrong, but my impression is that the display only goes blank with display activity from external MIDI data but not from display activity when using the PreenFM3 knobs and buttons. If that is so, would it be reasonable to think that a PERF screen without the oscilloscope would not go blank?

Thanks,
Phil

Great! I will try that firmware and report back.

Hi Xavier,

I have one more question about the display going blank:

Whenever this happens, pushing MENU and + always gets the display back to normal. The CONFIG setting to auto detect sometimes works, but eventually there is always a moment when it doesn’t work. That’s when I need to reset the display manually.

Wouldn’t it be possible to fix the auto detection to always work?
Or could the reset simply be automatically done at regular intervals?

Thanks,
Phil

Hi Xavier,

I tested the modified 107s firmware. My impression is that the slower update rate of the TFT hasn’t improved the issue and that the display goes blank just as often as it did with the regular firmware.

I guess I will have to try to replace the display connector and solder it directly.

But, in any case, the issue doesn’t really affect the usability of this great little synth!

Thanks,
Phil

Hi Xavier,

if you have any more insights about possible solutions for the blank TFT or anything else I could try to diagnose what’s causing it, please let me know!

Thanks,

Having looked at the files Vurt provided, I was able to export txt files from my own waves with Audacity that work with the PreenFM3.

Thanks for the help!
