K800 Display & Backlight ways - GSM-Forum

rjsoo7 · 10-05-2006, 00:16

Hi freinds,

I have K800 that had no White(Back) Light .. It was because of Water spilled on it.

Now I managed to turn on the phone , everything is OK except :

1- Back light
2- Flash light

Anyone knows the part responsible ? and where it is located

Thanks

Hallo,
Can you please make clear what jumper exactly you place?From pin 1 of the LCD connector to where?
Thanks a lot.

It works !!! I solder the no.1 lead anode to TP3100 spot and my k800i baclight is back !

What is groud, isn't it rather Ground ? (sorry for my bad english)
Where can i solder the ground An example of a ground spot on a k800i pcb plz !
Is it really important to solder the ground ??? Because i just solder the n.1 lead to TP3100, without soldering the ground, and the backlight works !

just make the jumper as picture that load from boengo, without the connecting the "groud". just from pin 1 to the point near the connector
