Question about LG KM900 Arena Cell Phone
My lg km900 screen got shattered, i have removed all the glass, but the touch screen no longer works. what should i do????
Hi,i think the inner touch pad of the LCD screen is bad and it needs to be replaced,here is a detailed guide to help you disassemble your LG arena;
Tools required: Phillips screwdriver, mobile phone opening tool, plastic tool such as a guitar plectrum or credit card, double sided tape.
STEP 1 Remove your back cover, battery, sim, memory card etc. Remove the four circled screws.
STEP 2 Run your mobile phone opening tool around the join of the front and back of the phone. Start at the top and then pull the phone apart when you can get enough of a grip.
STEP 3 A ribbon connector (circled) needs to be disconnected. It attaches like a plug and socket. Just lever this up to unplug. Next, peel the blue sticker off.
STEP 4 The circled ribbon connector needs to be disconnected. Just flick the black latch up and pull the orange ribbon away from the circuit board.
STEP 5 Pull the circuit board towards you. A little force is required but be careful as a cable is still connected to the board and you don't want to damage it.
STEP 6 on the left is a connector that disconnected when you pulled the circuit board towards you. Remove the screw, in the upper right corner. Disconnect the two ribbons beside the camera. Each attaches like a plug and socket. Just lever each one up to unplug. Lever up the white wire above the battery slot . Remove the blue sticky tape above the white wire.
STEP 7 Lift away the part above the camera. The ribbon connector needs to be disconnected. Just flick the black latch up and pull the orange ribbon away from the circuit board.
STEP 8 Pull the circuit board away from the phone. Note that the connectors,disconnect when you remove the circuit board. Lever up the wire at the base of the phone. Remove the 2 screws at the edges of the base . Peel back the silver sticker
STEP 9 Use your mobile phone opening tool to lever up the metal part bounding the screen . It's stuck down with double sided tape so using a hairdryer to heat the part may make it easier to remove
STEP 10 Slide something like the edge of a credit card or guitar plectrum under the right edge of the touch screen. Again, this part is held down with double sided tape which may be easier to remove if you heat it up a little first. You should replace the double sided tape when you put the phone back together.
STEP 11 Lift the touch screen from right to left.
STEP 12 Lever the two long stoppers out and then use the recesses as levering points to lift the screen out.
STEP 13 You should now have the LCD screen removed. Reverse the whole procedure for reassembly.
The screen costs only 39USD.
Thanks and take care
