SL7550 Screen

Postby tdats » Wed Sep 12, 2018 11:24 am

I have a SL7550 (not an E version) with a broken screen.

I ordered a replacement screen from Wiscom. After a long backorder from Motorola, including a part# change, I finally have the screen. Putting it in the radio, I get nothing at all on the screen. It just stays black, no flickers, no nothing. Putting the old screen back in, it works as well as it did before. (Lights up, lines on the screen, etc)

The screens do look different on the back.

Anyone know if mother M had changed some hardware or something? If so, anyone know where I can get my hands on a non e series radio screen?

Trying to rule out something like that before I pursue it being a bad replacement screen.

Sounds like a sales support question for your vendor. They do support their sales, right ?

if you don't have access to MOL support, then yes, as stated, call the vendor. There have been several changes on those radios. The new one is the new version with the JTAG port visible.

What is the FW version in radio? Upgrade it to the latest first. I remember the situation with XTS3000 where display mfg. was changed and required new driver to work. Driver is part of firmware package. I can't guarantee, it's just my expirience with another series radio.
I am biggest fan of XTS2500 and ASTRO Digital Saber.
