How to repair keypad problem in China Mobile

First we need to know china phone keypad connected with PCB how way
(A) Direct on PCB
(B) Flex System (flex cable direct soldering pcb to keypad panel)
© Flex and socket system include (flex one side soldering with key panel other side connect to pcb with socket)
(D) only Socket System (here have 2 socket, 1 with key panel others with pcb)
Keypad problem have various type
1. All key not work.
2. some key work and some other not work.
3. sometimes work and sometimes not work.
1. All key not work
china phone all key not work for this type of problem
(A) though its touch screen phone, first try to disconnect touch panel line from phone pcb or display flex (4 line)
(B) though not solve and keypad direct on pcb first you try to good clean full pcb with cleaner.
© though not solve now you try to format/flash your phone because some time key problem come from software problem.
(D) though still not solve now you check must be CPU. 95% china phone keypad directly going in cpu. and other 5% first going to resistor or capacitor near the cpu or keypad than going to cpu. so now first check them than you can try to re-hot, re-soldering or changing cpu.
(E) though its flex or socket system, first check GND connection continuslay pcb to key panel. next check full flex or socket all line going continuously pcb to key panel or not. also sometimes flex or socket shorted with other line or gnd so check also them.
(F) Also you can check all key anyone is short 2 line.
(G) sometimes keypad line broken from cpu pin on pcb to key panel, so check them.
2. Some key work and some other not work
Some key work and some other is not work for this type of problem
(A) maximum time this problem we face for flex or socket system keypad. so check flex cable and socket all line any line is broken or not and though need change them. and check all key connection on key panel.
(B) though its direact on pcb, some of key line broken internaly. and maximum china phone have alternative test point near every key or with other key on keypad. so check them with multimeter and though need connect to not work key with near testpoint or other working key.
© common problem is keypad metal ball (which is short 2 line on key when we press) sometimes its damage for phone water damage or over key voltage, so clean them or change.
(D) also try to check line continuously from cpu to not working key.

3. sometimes work and sometimes not work
this problem come from this defect
(A) flex or socket system keypad any line is bad soldering or do lose contact. check them and
re-soldering or keep there line join with extra ware.
(B) for cpu bad soldering or cpu pin is broken. so re-hot or re-ball cpu.

Sony Cyber-shot DSC-H5 Digital Camera power button does not work

In today's cameras on off button only give a pulse to processor to switch on.actually camera is on all time technically.only screen is off.Your problem may be flex connection to main board has failed. The group connector for on off, click, Tele, wide, all together forms one connector. Whole part to be replaced by camera technician to save your camera.

When I flip open my LGenv3...the internal screen is black and I have a good charge on it...what do I do?


there is nothing wrong with your screen, the problem is from the flex that connects your screen to the phone's main board. This flex must have worn out that's why your screen is not displaying any picture.

The problem is common with flip and slide phones. The flex gets worn out as a result of constant opening and close of the flip or slide phone.

I would urge you to replace the flex and I am assuring you that your screen will display picture again. You might also be lucky to find out that the flex is not well fix, that is, it may have loosed contact.

If you cannot change the flex yourself, maybe you should take the phone to a local repairer within your vicinity, so that the flex can be fixed/replaced.

Good luck.

Did not get a disc with my dpix 5200 camera im unable to send pic

Prakticam, unhelpfully don't have anything for their cameras more than a couple of years old and don't seem to care if you mislay the disc you paid for.So be warned, don't buy Praktica. I have the 5200, you have firstly to put your usb in computer, switch on camera, switch camera to view pictures taken mode, and because it auto switches to take picture mode you then carefully attach camera end into camera whilst camera is still switched on! Then go to my computer and click on F: the pictures download. Then to save them click on first pic, hold shift key down and then click on last pic they should all highlight, right click and then hover 'send to' and send by left clicking to my documents. I remember that it took me 4 hours to work it out. Found this looking for manual to download, cannot change date now......

No pictures

I also had the same problem - Finally solved it by reformatting the Memory Card on my Home Computer.
Note - It was not solved by using the delete pictures function on the V1253 Camera.
The problem only occured after I had used a friends Computer to delete pictures only from the Memory card.
Hope this helps!

Blurred Picture in the shooting mode

one of the possible cause of the said problem can be a defective or broken flex ribbion cable carrying signal to the focus motor. the replacement of the flex will solve the problem. othe may be friction in the focus assembly. cleaning of the same will do the job. but in both the cases you will need the help of repair shop.
