Maintenance and repair of all crashes lighting devices for laptops<\/b><\/span><\/div>\n<\/div>\n
There is no doubt that the lighting that we see too many problems we see warning lights dim or non-existent where we see on the screen the data, but without lighting Here comes the role of the process responsible for the lighting elements<\/span><\/div>\n

Inverter<\/b> or inverter or the so-called inverter.<\/span> (Neon Lighting Department)<\/span><\/div>\n
Lighting department found the bottom of the laptop screen. They serve as neon necessary effort to light up the screen.<\/span> And called by that name because his job lies in the conversion of the DC voltages, AC voltages to a voltage fed by neon bulbs in general.<\/span><\/div>\n
This inverter feeds generally on DC effort and it is often 12 volts to 24 volts.<\/span> It feeds on your laptop or Two efforts on three main effort will be from 12 to 19.5 volts<\/span><\/div>\n
The effort needs with basic effort and another is either 5 volts or 3.3 volts to be working properly<\/span><\/div>\n

And too many breakdowns lighting circuit because it depends in its work on several key functions and sub \u200b\u200bbasic function is neon lighting and also his job to control the level of lighting.<\/span> Because he receives several orders arrive from the keyboard to input and output circuit in motherboard him directly and through this signal we can control the level of lighting.<\/span><\/div>\n
And in charge of this process, the FN<\/b> key<\/span><\/div>\n

Here socket income consists of six parties also note<\/span><\/div>\n
The first and second party IN<\/b> are one party as shown when the arrow No. 1 and are responsible for the coming of Almadhirbord core voltages hyphen through small cable outside of the cable screen<\/span><\/div>\n
<\/div>\n
Third party and as it is called the ON-party<\/b> which the party responsible for the lighting process began<\/span><\/div>\n
And referred to him by the arrow and is No. 2 job in the reception of a signal coming from a small Bvoltaip Almadhirbord in case of quitting.<\/span><\/div>\n
When you receive this signal function inverter begin to turn next to Almadhirbord voltages of voltages you need neon lamp in the screen as we explained before<\/span><\/div>\n
<\/div>\n
Fourth party as it is called by the the ADJ<\/b> and referred to him by the arrow No. 3 which is the party responsible for Zbt lighting comes the function of this party after the third party and also receives a fixed signal at the beginning of takeoff and through given run the appropriate lighting during take-off device is also the party that receives the signal coming from The FN<\/b> key upwards or decrease lighting<\/span><\/div>\n
Fifth and sixth party, a party one as seen and referred to them by the arrow No. 4 They GND<\/b><\/span><\/div>\n
Or as we call it Ground party<\/span><\/div>\n

In general this group is often the cause of most of the problems inverter damage and lead to mute Alpaor or voltage fluctuation causing malfunction of the functions that we talked about, especially in small transistors by the adapter is often the reason Tfahm touches one end of the screen Cable<\/span><\/div>\n
