7210 powers up but no display - GSM-Forum

GB904150 · 01-02-2004, 00:31

Hi,

I've got a 7210 which powers up but just shows blank screen. I have tried flashing with 4.74 firmware with cheap china flasher but still nothing.

Do I need to change the lcd or is this because cheap flasher is not good enough to solve problem?

thanks to all.

raheeeeb 100% right , you will also notice that if you try to press on the screen connectors it displays , then you can fix the loose contacts.
