The large screen of LED is like the traditional electronic products which need to be paid attention to use methods and maintenance, so as to make a longer service life of it.
The computer is usually placed in the control room, thus to keep the stability and good displaying result, we must maintain the main control computer regularly as follows:
Keep the control room clean and regularly dedust the computer and surrounding equipment, as dust may contaminate the keyboard, disc, display, host circuit board and other important parts, causing material faults.
The computer will produce a lot of heat during operation. If radiating is not sufficient and the room temperature is too high, computer crash and other faults may be easily caused and the service life of the main control computer may be reduced in a long term. Therefore, ventilation must draw enough attention.
If the environmental temperature is relatively high (e.g. in hot summer), the control room must be installed with fans or air condition equipment if applicable, so as to maintain the temperature as 10℃～ 35℃ and the relative humidity 30%－80%, and try to avoid working of computer under high temperature and high humidity.
Regularly examine the hardware and surrounding accessory equipment of the computer, e.g. whether or not the graphics card and sending card is loosened, whether or not DVI line, serial port line or USB line is loosened or damaged, and eliminate discovered problems in time.
Kill virus regularly, especially that the computers connecting internet shall be installed with anti-virus software. And the player software shall be upgraded regularly to assure the latest version is used.
The more stable computer power is the better. Usually it is required to use AC 220 V±10% with frequency of 50HZ±5%. A fluctuate power can affect the normal running of computer and directly affect the regular displaying of display, thus it is suggested to add one UPS, if possible, which will protect the computer data from missing due to sudden blackout of main supply and also has voltage stabilization function generally.
If there’re refrigerators or air conditioners of high-power surrounding the computer, the power socket of the computer shall be separated with theirs and use independent power socket.
As safety assurance, the computer power shall have good grounding system with three-phase power socket of null line on the left, live wire on the right and ground wire on the top. The ground wire here is the safety wire of power, which shouldn’t be connected with the logical ground line of the computer.
Examine whether or not the power works normally and whether or not AC wire is loosened. Examine whether or not the fan works normally, and dedust the fan blade.
Examine the receiving card: Check whether or not the supplying DCSV wire is loosened and whether or not the receiving card and keyset are well contacted as well as whether or not the winding displacement of keyset is loosened,
Visually examine whether or not the DCSV wires and winding displacements between the internal modules of the cabinet are loosened.
Examine whether or not there are sundries jamming the air-vent, and dismantle the anti-dust net to clear off if so.
Examine finishing of the display to assure safety usage of it.
The maintenance passage ladder of display shall be at least three meters and be additionally installed with protective door and relevant warning boards.
For the display part, mainly conduct regular dedusting on the surface of display especially for out-door display which is long-time exposed to the work environment of wind, sun and dust and can be easily contaminated. Thus, regular dedusting of display can not only elevate displaying effect but also avoid the acid particles and other chemical substances in the out-door environment to corrode the surface of display under humid condition, so as to improve the service life of display.
For out-door display, install efficient lightning-protection equipment if necessary. The following issues shall be noted for application and maintenance of LED:
Preservation of the non-installed display, standby modules and other accessories
Usage and storage of LED under special environment.
