89. Remote Repair
With time on consoles, some buttons do not work. Especially when used in a kitchen or other "dirty" areas. With this remote stopped working some of the buttons, for example «MENU». Open the console, it needs podkovyrnut latch. There are panels that hold more than latches and screws. Remove the keyboard, here seen a lot of dirt between the keys on both the front and in the field of sensors under the buttons. Due to the quality of the last dirt of the remote is reduced. Also see broken off button, but it was done at the factory. It is strange that so accurately. Maybe not at the factory do it? All washed out, can be directly under the water and soap. The only fee then you should immediately wipe dry and dry, so that nothing is oxidized. So look clean parts: Now collect dry cleaned items. That should do it. I have all the buttons work well, just like on the new... read more
90. Mouse Repair
One of the most common reasons that a mouse can not work - it is an internal broken wires on the battery cable to the mouse. Computer mouse whether USB or PS/2 uses five wires. One screening, two supply and two for data. At break of at least one of them, except the shield, the result is - the mouse does not work. It is possible that some details do not work, for example, Wheel or button . Consider the repair of such a failure. We first analyze the mouse by unscrewing the 4 screws that are under the pads slip. There are other mounting structures, but this - the most popular. dismantled mouse In different mice of different wires connected to the main board: there are soldered connector are connected. This motherboard uses a connector that can be turned off, remove the wire from the mouse and have to work only with him. Remove from the damaged section of the outer insulation. If the bend in the wiring region of greatest... read more
91. PC Speakers Repair
Virtually all electronic appliances has inside voltage converters. Typically, this transformer. In the columns, which I repaired, this is the spoiled "converter". He is not burned out, as is often the case, and the fall broke holders and lost leads. But in the article, it goes on the reasons for failure, but about what this transformer can be replaced to fix the broken speakers or anything else with a similar malfunction. Columns needed for the AC voltage of the order of 9-12V (this was the output transformer). If there is a similar transformer, there is no problem - change it and continue to use it, but I did not have it and do not think that many of them lying around in abundance. In most devices, the AC voltage from the transformer is converted into some constant simple circuit such as a diode bridge with a capacitor, so instead can apply AC and DC. But where can I get it? DC voltage source, which have everyone Chargers from mobile very tenacious... read more
92. Mouse Button Repair
Illustrate wireless mouse HP It began with the fact that the left button is pressed perceived only with considerable effort, and when you effortlessly fire every time. If the mouse button is not working, and it all started similarly, then remount the same plan. Mouse wheel is also not eternal, its recovery is described in the article «Mouse wheel does not work». It was decided to get to the innards are not running the mouse and clean the contact sites. To get to the mouse buttons would be nice to make out. With these difficulties have arisen: Remove the two screws in the battery compartment and the case was opened: The photo below shows the culprit. A little button on the center of the photograph next to an inverted sign SW1: Now you need to disassemble the button itself Its upper part is sitting on four plastic pins on top of empty seats. This mount neatly cut away the office knife, they also podkovyrivaem and remove the upper part. Now we have... read more
93. Fix Mouse Wheel
Using modern pointing devices, we can face the problem of non-working mouse wheel, or working properly (when scrolling page "torn" up-and-down), which affects the final result of the same - use the scroll wheel does not help to use the computer, because the wheel does not have a mouse working. As a result, we do not use or scrolling or looking for a different mouse. The same problems can occur with the buttons, but what about in the article «Mouse button does not work». But the drawback is easy to fix, unless, of course, the problem was the result of severe physical effects (impact on the mouse with the breakdown of mechanical components and circuit boards or flying into the wall). To start our analyze the faulty mouse. On most mice mounting screws are hidden under the sliding "pads". These moving elements are kept on double-sided adhesive tape and can be temporarily unstick to get to the screws. Open the mouse body. To remove the wheel and release the... read more
94. Timing Belt Replacing of CRDI Engine
Timing-it's gas distribution mechanism, timing belt-one of the most important parts of it, and it can not work without the motor (unless, of course, the engine design involves the use of timing belt). Gas distribution mechanism-a system for those items that provide input at the right time of gases in the cylinder, closing all valves for converting combustion energy into mechanical and gas output-products of combustion. The engine CRDI D3EA timing camshaft and crankshaft are carried out through the gears and belt. Camshaft gear has teeth twice than crankshaft. That is a half-turn cam has a crankshaft revolution. It is necessary to change the timing belt at the time, declared by the manufacturer, or earlier, as the failure of a timing mechanism in the turbo diesel will lead to the meeting of valves and pistons. Although it is possible that the camshaft will rise to a position where all the valves are closed and then nothing bad will happen, just need... read more
95. Replace Glow Plugs of CRDI Engine
Glow plugs in diesel cars help cold engines heat the air and fuel mix up to ignition temperatures. This becomes more important during winter due to the freezing cold temperatures. An engine in good condition will ignite without any help from the glow plug when the temperature outside is around -5 °C or higher — I've checked this myself. But when it drops to -8° C or below, things change: the engine gets much harder to ignite, and draining the battery sooner becomes more likely. Glow plugs are perishable goods, since their lifespan is much shorter than that of an engine. I used to replace them every 25 — 30 thousand kilometers, which always happened by the beginning of the winter. By then you could feel that the engine needed the glow plugs in good condition. Feel that when the starter began to spin, only one cylinder was igniting. Then, after a few more spins, the other cylinder would start ignite and the engine finally started. A glow plug has... read more
96. Replace Hydraulic Lifters of CRDI Engine
A hydraulic compensator is a hidromechanic device that changes its length and compensates for the thermic gap between the valve and the camshaft. It has two parts: an external cylinder and an internal mobile part propelled by spring. At the entrance of this device there's a valve which consist of a ball pressed by spring. How does the compensator change its length? It's actually a pretty simple process: there's a spring inside the device that gets stretched to its maximum length when the compensator isn't compressed. At the same time, during the movement of the internal part the device is filled with oil. The compression process is much more complicated since the valve won't let the oil out easily. However, due to small gaps between friction surfaces, it will slowly come out. If the device is compressed while it's working, the oil won't come out, unless you keep it compressed with a clamp and wait. Hydraulic Compensator in the Engine The valve is placed with its... read more
