T720 T722i External LCD Display Flickering Fix - GSM-Forum

Rocklobster · 04-20-2004, 21:29

I found a simple solution for anyone experiencing an outside/external backlight flickering problem from replacing a mismatched generation LCD screen.

There's generation 5 (originally used on the T720 which is part # LPH9029-5), and there's generation 6 (used on the T722i which is part # LPH9029-6).

Use the MSS ".display" file(s) below for the correct version of LCD you have installed. (delete the .TXT extension after saving)

Please note that these files apply to T72x models ONLY, do not write these files to your phone if you do not have these models!

Hope this helps anyone in need:

I have a T720 which came with display model LPH9029-6. I can't get the outside LCD to turn on anymore (after unlocking it). If I put the gen6 flash on, the internal display stops working and external turns upside down. gen5 flash makes it work, but external LCD backlight stays off. If I update to T720i software, the display works (with the gen6 file) but I lose 400 phone book entries and VoiceNotes
