I bought the h6340 and it turned out to be invisible to any card. disassembled looked carefully especially contacts all okay. after looking more closely, I noticed a pocket (cap on top) for the card from one corner slightly raised, less mm. it turned out the pocket is fixed at the edge of the board with 2 sides sealed. and in 2 places of each guide (sled) on each side, there are protrusions behind which the pocket snaps in and presses the card to the contacts (more precisely, they press the contacts). The 2 tabs on the 1st side were broken and the card was non-contacted. tied a cap around the corner to the board now works!

I recently repaired the CF connector once. He left the CCP for a few days with relatives, and about human curiosity ... As a result, 4 CF contact plugs were bent. It was not possible to correct without analyzing. I had to open the CCP, since there were skills. I opened the device, took off the metal cover of the connector and adjusted the contacts and at the same time noticed that 2 contacts broke off in soldering. Soldered, fellow "car" and about a miracle everything works. By the way, the device HP 2490.

Useful tips:

1. ABOUT GUARANTEE.
Before you fix something with your own hands, you need to make sure that the device is non-warranty.
If the warranty, it is best to carry a service center.
In the case of self-repair, you will lose the warranty and perhaps it is better not to move on to the following points, but quickly carry the device to the warranty, where competent specialists will repair it qualitatively and for free.

2. TYPE OF PROBLEM
The next step is to determine the mechanical problem or software.
The topic can help in determining the cause.Hangs up or does not turn on the PDA, help topics in the device sections.
If the problem is software - use the tips of this topic.
Any software problems - firmware, OS, radio module, installation, removal of programs can be solved without resorting to the mechanical effect on the device! Remember this!

3. SOURCE OF THE PROBLEM
If the problem is still mechanical - it is important to determine exactly what does not work - the inside of the device, its screen / touchscreen, rechargeable battery, headset, SIM card, memory card, charger and the like.
The following topics will be useful for the definition:
but) Questions and problems with the battery or charger
b) Questions and problems associated with touchscreens, screens
at) Bluetooth headsets and troubleshooting
d) PPC FAQ
d) Features of operation of SD and SDHC cards
e) What to do if you hit the PDA in the water?

4. SERVICE CENTERS
If you are convinced that the problem is not in the battery, headset, charging, SIM card, memory card, etc., i.e. in the animal it is recommended to ask in the topics sectionRepair and Service where you need to describe your problem in detail.
Perhaps, if the experience of self-repair is missing or extremely small, it is better to use the services of these or any other serious service centers (hereinafter SC), where you will be repaired with a 100% guarantee of your device, even if for some money.

5. PREPARATION FOR REPAIR
HereYou can give the following tips:
but) Look attentively FAK on your device, a topic with a discussion of it, use the forum search with keywords on your problem - maybe someone has already come across it.
For example - the HTC P3300 device has a long-known problem - do not drink proca. The symptoms are different, but the device can reboot, switch on, and the like. The solution is to solder the contacts in the SC.
b) Learn the subsection Personal experience - maybe someone has already solved the same or similar problem.
at) It will be unreasonable to make a global search for your problem on the Internet, taking into account foreign forums using search engines Google.ru, Yandex.ru and the like. If pages are found in a foreign language, translate them with Google language tools. The translation will not be accurate, but more or less understandable to assess the magnitude of the problem and may suggest a way to solve it.
d) If there is nothing, start writing a post in this thread. Describe in detail the problem, attach photographs, screenshots, any information obtained through different channels, such as suggestions from service centers, found data of similar problems and so on. The more you describe the problem, the sooner you will be helped. Give a link to this post in the topic - discussion of your device.
d) Be patient - many forum users do not sit constantly on the forum. Let me remind you - raising the topic by forum rules is not welcome. If someone knows the solution to your problem, they will help you!
e) In the case of a proposal to repair a device for money, think about how important it is for you and if you don’t pay more than this device costs, and even not having 100% certainty that a non-specialist will fix your device? Perhaps it is in this case to ask the price of repair in a serious SC and make it there.
g) In the catalog General catalog disassembly devices or Schemes and service of PDAs , on the SC sites or in the FAKs on our forum you can find instructions for disassembling your device. They are also found in free access on the Internet, in English-speaking and Chinese forums. Agree - having a disassembly instruction is a good thing. Use the search!

6. REPAIR
If, despite all my persuasions, you decided to take advantage of advice or help from this topic - do not say that youDO NOT WARN! The risk of losing a device or turning it into a brick when self-repairing is extremely high!
All that can be found on the Internet and on the forum, all the tips reread - proceed to repair. Who smokes - we make a smoke break.
but) It would be nice to invite a friend of a telemaster or just a person knowledgeable in electrical engineering and connect to the disassembly / assembly of the device - the help of such a specialist is never superfluous. In addition - he knows how to properly handle this technique.
b) Write on the sheet in which order you disassemble the device, map the fasteners with the sequence of their disassembly, take pictures of all the key stages of disassembly. This is necessary for proper assembly of the device without unnecessary parts.
at) If an obvious problem is detected (some kind of plasmask is broken, the wire is broken, the contacts of the microcircuit are oxidized, capacitors are blown up, the choke is melted, etc.), you can evaluate whether you can repair the device yourself. If yes - to make all operations with special care, without damaging the whole elements of the device. If you glue, then glue is not too corrosive to the plasma, if you solder it - with a thin and low-power soldering iron, if you clean it - with pure alcohol without strong pressure, etc. If you cannot repair the device yourself, it is better to assemble it and take it to the SC with photos of your breakdown. There they will be able to roughly estimate the complexity and cost of repairs on the photo. BUT NOT THE FACT THAT THE PROBLEM IS ONE AND ONLY IN THIS!
d) If you have disassembled everything that you can and did not find anything, collect and carry them to the SC. Most likely - your device requires special knowledge and equipment.

7. IMPACT OF REPAIR
but) did you succeed? Congratulations! You are a very experienced person. Describe everything that you did in this topic, attach photos - maybe your instruction will help someone!
b) In case of unsuccessful repair in case of a burning desire to save the device, the last thing you have left is to carry it to the SC. Perhaps - a chance to revive him still remained.

If you have read all this and have taken a screwdriver and a soldering iron in your hands, all that remains is to wish you success!

LIST OF STANDARD MECHANICAL PROBLEMS WITH DEVICES AND THEIR ELIMINATION METHODS
Will be supplemented with the accumulation of information.

PDAs and Communicators

Problems screen and touchscreen:
1. The touchscreen crashed or some part of it does not respond to pressing. The screen at the same time shows.
The solution is the replacement of the touchscreen. Discussed in topicTouchscreen replacement on touchscreen devices
2. The screen crashed with the touchscreen as a result of a mechanical impact on it.
Solution - requires disassembly of the device Carefully disassemble the unit, remove the main board. We look at the back of the screen. There should be a number, for example TD028STEB2 (Asus P535 screen). Or you can find the screen number in the internet by the device name. Also on the Internet looking for where to buy it. We buy together with the installed touchscreen. We change and collect the device, load, calibrate. Everything.
3. The screen when you open the keyboard slider becomes black / white.
It is possible that the loop of connecting parts of the device and the keyboard is frayed. It is necessary to ring and possibly replace the train.
4. Invert colors on the keyboard slider screen.
Most often, a software problem related to a specific firmware or a wrong version of the bootloader is stitched. But it is possible - the loop is faulty.
5. High-frequency whistle touchscreen.
You can decide in this way - pour the choke on the main board with paraffin or wax.
6. A seemingly oily stain under the touchscreen (covered with glass, capacitive technology, or not only).
Probably caused by pressure on the screen. If there is, remove objects under the battery, pieces of paper, remove the memory card (it may be thicker than similar cards from other manufacturers / volumes). If the stain is left - you need to replace the screen with a touchscreen.

Problems of contacts and external devices.
1. The wired headset does not receive a signal from the device.
The solution is a neat cleaning with a wooden toothpick on the device. More solutions can be learnedhere
2. The HTC P3300 device, restarts itself, does not turn on and so on.
The solution is to solder the processor contacts in the SC.

Smartphones and phones

Laptops and UMPC

1. When the charging is connected, the battery charge light blinks, the laptop does not turn on when powered from the battery.
The solution is a unique replacement of the battery, due to its deep discharge and failure of the battery controller.
