Have a Motorola XTS 2500 III. The display has been replaced and since that moment, it shows nothing more, but lit the backlight! Programming it was the last Astro 25 Portable CPS Version 8. Is it possible that a new display driver is required? If so, this is only the program by a newer version of CPS?

Sorry for my bad English ... i'm coming from Switzerland ... and here can nobody help me with this problems.

There is no new display driver, like what happened to the XTS3000's 2 versions of it's display.

Sounds like there is a problem with the radio itself - not the display.

carefully inspect the connector where the display plugs in for bent/disformed pin.

You can power the radio with the front cover off, gently press the display
connector while powered up and see if it comes to life. There may be
a cold solder joint on the radio's side of the connector. Seen this problem
in the waris radios a few times before.

Good luck

Thanks for the tip. I tried but without success. The backlight works from the display. Where can I still here after an error? Or is there a way of testing?

I just repaired a unit (XTS2500) last week with the same symptoms. The problem was the with the flex connector. It had several bad solder connection, and I had to re solder the connector. It was very hard to see, so inspect that very carefully.

Jim

this part on the first 2 pictures or another part on the other pictures ?

Picture number 4, it was the bigger connector. The bad contacts were closer to the outside edge of the radio also.

Was the old display working before you changed it? I assume not, but I still need to ask. I would try the display in another radio, or try a known good display. Is your radio a factory radio? Is it a Model 1.5, 2, or 3?

Yes before it was broken then everything worked. Is a Model 3!

How did the other LCD get damaged? Dropped, crushed, did the old one just stop working?

Have you tried another LCD, or tested the replacement? It would not be the first time that an LCD is DOA (bad out of box). That is the first thing I would check.

That display was pressed. Not so much but it was nothing more readable. Therefore, it was exchanged.

No, unfortunately I have no other displays available. This is my Problem and here i can not buy any ...

Where was it exchanged? If you cannot buy any, the exchange had to come from somewhere right? Maybe try exchanging it again and say that the display is bad out of the box... Just a thought.

Yes, I'll probably try this path to a new display.
I thank you in any case for good help! If anyone has an idea that he should only post;)

I have rarely seen so good forum! Respect! Keep up the good work.
