Tractor Numeric LCD Display Issues: Fix Partial Digits, Replacement & Soldering Tips

Question

Hello. The counter in my tractor does not display the whole digits. I dismantled it, I am looking for a solution. I do not know how to find the right display to replace it. I tried to heat it with a soldering iron, but probably too high temperature on it flooded the front glass. Please advise me about this do.

If there are no cold solders, the display needs to be replaced.

Is it cold February at the displays or at the control board? I have been looking for such a display for two days, but I have not found a similar one. 50mm long 17mm high, four digits.
What to pay attention to when looking for such a display I have already talked to three TV service technicians and each of them only offers help in soldering a new one. It is best to commission this repair to someone appropriate, but in my area I have not found anyone so far.

If only so that it cannot be re-soldered Apparently that's what you need to get. Enter exactly what type of car it is, it will be easier to search.

Tractor model; Deutz Fahr Agrocompact 70F3 Nothing will help on the website, only a new counter As for my question about the number of feet, all of them I found were symmetrical

I corrected all February on the board and it did not help. Unfortunately, I can not find a similar display with 15 pins. I guess no one will help what to do, you have to drive like this; Subject closed.

Wait.
The display works, did the heating do it?
The display is made of glass with ITO tracks. Legs are mounted on these paths. They are often additionally glued to the glass. I know that if there are no cold solders there is probably no contact there. Try to pinch them with a probe from the gauge. If something improves, it can still be done.

In the first photo you can see some kind of slime on the display. Is it just some debris or a damaged display?
