MY LG GT540 IS ONLY 3 WEEKS OLD. I MADE A CALL OR 2 AND A FEW TEXTS LAST NIGHT AND I WANTED TO MAKE A CALL THE NEXT DAY BUT ITS SAYING THAT CALLS TO THIS NUMBER ARE NOT AVAILABLE. I HAVE PLENTY OF CREDIT...


The phone is three weeks old, you are paying the freight, your phone is not operating as advertised and your carrier is not sure what to do. Take it back and make them show you how to work it. If it doesn't work for them and they can't fix it make them replace it.

Joystick problem


The joystick tends to be a bit of a problem on the K series. It's not so much the build quality - it is extremely strong and durable.

The main weakness of the joystick is the poor shielding from dead skin etc that falls into the gap, floats around, and gathers in the base of the joystick. This gums up the joystick, meaning it needs to be pressed HARD to push through the **** and operate the micro switch.

It is impossible to clean with brushes, cotton buds, cmopressed air etc. The crud needs to be broken down and washed away. The simplest way to do this is with electronic contact cleaner. This stuff comes in a spray can, with a long thin tube that fits into the trigger head.

This is what you do:

Go here to learn how to dismantle your cell (that link suits K750/W800).

Once you have the cell in pieces, grab the mainboard and contact cleaner and come back here.

Fit the tube to the triggerhead and spray the contact cleaner deep into the base of the joystick. Blast it in there for a few seconds then let it drain a bit, then repeat several times. Then repeat. And again. Get rid of all that crud messing up your beautiful cell icon_smile.gif

You'll feel a bit freaked out using contact cleaner. It runs off the circuitboard like water or very fine oil and you can't help but wonder if it's going to cause damage. But the beauty of contact cleaner is it evaporates without leaving any residue, and so it won't damage the mainboard at all. It also shouldn't set off water damage indicators.

Don't spray it on the lcd though (just incase - my k700 one went a bit funny, but then came good after a day). Keep the lcd away from the spray area.

Give the board a minute or two, then reassemble phone and test joystick. You should find a radical improvement. If still not 100%, try the whole process again, untill you can get no more improvement.

If after that it still isn't working properly, then your up for a new mainboard or to have a new joystick soldering in.

Hope that helps any game peeps out there who wanna fix their joysticks themselves.

It got mine sorted - it's like brand new icon_biggrin.gif

My sony erricson k750i phone's joystick is not responding


you have to clean the joystick by using contact cleaner. open the cover of joy stick, there is a switch inside it having a metallic cover. use contact cleaner and let it for few minutes.
DONT FORGET TO REMOVE LCD FIRST. it can be damage with contact cleaner. i had a bad experience of it.
btw it happens with sony ericsson phone joystick problem.if joystick problem still persist u have to show it to sony ericsson repair centre or your warranty center of mobile.and u can also use the keys your keypad keys for up down left right.
thankyou.

Z525a screen comes on but stays vacant.


If you have access to a laptop computer that has an Infrared Port or Bluetooth communications, you can download your videos and picture files via either of these two methods. I use an old IBM Thinkpad 600 with IR port to download mine. You have to put your z525 phone into Infrared mode first, its kind of tricky with out seeing what you are doing. First, open your phone, press upper right (-) sign to get menu, click joystick control down 2 times then right 1 time. next press upper left (-) sign to select. next joystick right 4 times, and down 1 time. press upper left (-) sign, then joystick up 1 time. press upper left (-) 1 time. Your Infrared Port will now be turned on, and your I.R. enabled laptop can now receive the files from your phone. Close your phone, open it again, press upper right (-) , press joystick down 1 time, then left 1 time, then press the joystick center select button 2 times. Joystick right 1 time, press joystick select 1 time. press upper right (-) 1 time, joystick down 5 times, joystick right 1 time, joystick down 3 times, joystick center select 1 time. Hold the lower left corner of your phone toward the I.R. port of the laptop, it will receive the first photo file in your camera pictures file. Another possible method would be to obtain a usb connector cable for the z525 phone to connect it to your computer. Using the usb cable the computer would recognize the phone, you could click on the phone icon, under "MyComputer" and transfer the files to your hard drive. I hope this helps. -Mike
