D 900 no lcd - GSM-Forum

Crumarix1 · 11-27-2006, 22:25

Like I say, I have 2 D900, with almost same problem.

When power on, its appears only backlight, and nothing on the screen. On one it can see color vertical line, but very tiny, and not on full screen.I trayed change flat, with new one, and with each other, but result is the same.

Of course, also I trayed full flash ( USTPRO II ), but result is same.

I'm interested does it my problem unique, or maybe it's big hardware failure on that model, because many LCD support electronic elements is based on other side of keyboard,on seems to me, very tiny motherboard.

Both phone is looking very well, without any external damage,almost new.

I can test to change complete LCD Boards because I don't have at the moment any available , but I will tray and after that I will post result.

Now, I need any others opinion to solve my problem

there might be chance that the connector of the lcd flex cable got moist or dirty, try lightly brush the connector and the lcd flex cable first, then check the lcd flex cable if brushing doesn't help. Last resource is the lcd screen.
