Haii have a touch screen problem with my o2 xda atom.there is no responses when i touch the screenbut the screen looks fine.i have tried bought new lcd and get installedunfortunately the screen fail 2...


More than likely, the small ribbon cable that goes between the touch matrix and the connector on the mainboard is damaged. Ether the ribbon cable, or the connector(s) itself.

Touch screen shows wear and tear


Hi,
LCD will be replaced as there is no cure for wear and tear on its surface. Required LCD part number is appended below:
A1334748A... FTS BLOCK ASSY (35STMG07)
Available in Sony Parts Store for $154
If you are handy with electronics stuff repair then can replace it easily, remove side and bottom screws and take apart front and rear cabinet of camera. Unlock connector that holds lcd flexible connection wire, remove solder connection of back light source plate from lcd flexible wire, solder back light connections in new lcd flexible wire and insert it in jack on main board of camera.
Local camera repair shop will help you to replace lcd if you feel uncomfortable doing so.
Thanks.

My dell axim x30 backup battery needs replacing. Is this something I can do myself?


i believe if you are a bit of a hands on type of person you should be able to do this yourself.
but not without researching !

read this page, should tell you everything you need to know, from the perspective of someone who had to do the same changing of the CMOS battery.

http://www.mobilitysite.com/boards/x3-x3i-hardware-troubles/96005-x3-backup-battery-revealed.html

or read below:

quoted from: Tenc hi4U

DISCLAIMER : I take no responsibility for any damage you may cause to your Axim. The parts and proecedures described in this guide refelct my own experience with my own Backup Battery (BuB) in my girlfriend's Axim X3. Your mileage, parts, anbd experience may vary.

Tools needed for successful BuB replacement:
1. fine tip jeweler's screwdrivers (helpful if you slightly magnetize the tip)
2. Varta V20HR rechargeable NiMH battery
3. electrically conductive silver epoxy
4. strong needlenose pliers
5. electrical tape or heatshrink (razor blade or scissors to cut to shape)

But here it is step-by-step:

1. Pop little rubber caps from 4 corners of back covers. Disassemble Axim X3 with small jeweler's phillips head screqwdriver. Be sure to plave all parts in a plastic bag or other container (4 scres rear cover, 2 screws near port). Disconnect the ribbon connector towards the bottom of the PCB and the speaker wire (also on the lower portion of the PCB). Backup battery should be the green covered circular item under the pcb).

2. Locate backup battery, Cut away BuB cover, & CAREFULLY use strong needlenose pliers to grip and "roll" the leads off of BuB.Be very careful with the leads.

3. Mix dime sized batch of silver conductive epoxy (do NOT hot solder this battery, heat will lead to BuB damage and destroy lead connection to wire).

4. Apply epoxy to both sides (not too much)and afix respective leads to respective side (red lead goes to +, black lead goes to -). Secure connections with some type of clamp (I used a binder style paper clip, but a wooden close pin or something else that will hold the leads to the BuB while the epoxy cures (Mine took 24 hours to cure).

5. Recover new BuB with protective covering (I use electrical tape cut to the shape of the BuB. Covering WILL have to be form fitting to fit back into Axim BuB "slot".

6. Reassemble and charge Axim and charge.

Only works in playback mode


If when switching from playback to LCD then Viewfinder and no preview display is visible in either LCD nor viewfinder then the switch is not switching. If the red battery light is on try new batteries as some functions are unavailable with low battery power or connect the AC adaptor to see if power is a problem. Does the menu work? Does the zoom function move the lens? If all is functional in the playback mode then the switch may not be making contact internally. Carefully apply pressure to the switch while slowly moving it between all 3 positions while seeing if any display changes both through the viewfinder and the LCD. If you are technically confident you can open the camera case and try bridging the switch poles with a small screw driver to see if the switch is defective or misaligned. EBay has had DiMAGE cameras listed for 'parts only' very cheap but the Z3 would not merit the cost of a camera repair shop. My last successful bid for a Z6 was $200 2 years ago. My first repair on a digital camera was pretty simple since inside the case is a single printed circuit board with little ribbon connectors that can be reseated at ZIF type connectors. Just be careful, slow and keep track of the screws and parts orientation. Any friend who fixes laptops can help you but a shop will cost you more than the camera is worth. Good luck.
