1. We guarantee to the buyer of the equipment supplied is new, complete and unused.
2. To support the operation and maintenance of contract equipment, technical data provided by our factory ensure complete, clear, and the right.
The pre-sale service
Customer specific engineering design scheme need, please contact us, our designers will be on the construction site and product specific design, a detailed exploration and study repeatedly, free to provide free technical solutions.
Installation and debugging
1. Our company will send professional and technical personnel to the site for installation debugging. In the process of installation and debugging, my company's technical staff will take absolute responsibility for equipment will strictly in accordance with the requirements of the solution and product factory specifications for installation and commissioning of science. Such as the special cases need to changes of part installation antipathy, we with a negotiated solution. Our company will be completed fully ensure the installation and debugging time. As a result of nature or the buyer artificial reason to delay, the two sides will talk things over solve.
2. Debugging qualified standard: the standard stipulated in the instructions will be in my company as the standard.
The use of training
Our company will provide a detailed list according to the contract product manual, system use the specifications and system maintenance. To the user for the following training: system use, system maintenance, equipment maintenance.
1. Warranty purpose: response in time, as soon as possible to solve, make sure you use.
2. Warranty period: the warranty, screen body from all maintenance services; Over, after the warranty period of materials used in charge maintenance service costs, not charge labor.
Q1:What is a static screen, what is to scan screen, what is the difference between the two?
A:Static screen refers to when the led screen display text, images and video, the lamp is lit at the same time on the led display light;
Scanning screen refers to the light like a scan on the led display, is the advantage of the characteristics of the human eye of persistence of vision, in a short time period will be led display all light respectively.
The difference between the two: because the LED display is driven by duty ratios, which makes the brightness of the LED display has a lot to do with the light of time cycle. So, in the same light tube with the same brightness, static screen is higher than scanning the brightness of the screen, so commonly used static screen need high brightness in the outdoor show, the scanning screen commonly used in the interior of brightness demand is not high, driven to save cost.
Q2:Display image is not complete or position is not right?
A:1,. Firstly check "display position" in the software and the "screen size" of the parameters and display the actual size is consistent, if you don't remember, can go to see behind the screen body, calculate the screen body length and width of the pixel points. "Screen size" is determined, can go to the computer software in and see how much "screen display area", and then adjusted, until the position match.
2, if the display is not comprehensive, checks the screen connection to load the file is in agreement with the screen "screen size".
3,plays in the image is in agreement with the screen size, some image for 16:9 or 4:3 ratio, so released images won't full-screen playback.
Q3:There is no sound LED display screen?
A:1, confirm that the computer sound card, use the earphone test. If there is a voice.
2. Confirm the computer sound output problem is normal to the screen body contact amplifiers, and the power amplifier to the audio cable is normal.
3, once again confirm the computer sound card and other equipment have sound card without conflict.
Q4:Unit module, one or more lines are not bright?
A:1, use multimeter to check out a line with the 4953 IC (manager) if there is a general output pin.
2, use a multimeter to check 74 hc138ic input and output is normal.
3, using a multimeter to check if 4953 IC burning or burned.
4, using a multimeter to check whether there is high level 4953 IC (voltage).
5, use multimeter to check 74 hc138 and 4953 control foot pass.
Q5:Display jitter (scintillation) have stripes?
A:1, check whether the DVI signal line contact is in good condition, and signal lines are in good condition, the presence of poor contact, or the signal wire RJ45 crystal head with and without oxidation phenomenon.
2, check the signal lines for damage phenomenon.
3, check whether signal lines with high voltage cable, identified and separated. (signal wire and cable, power supply of electromagnetic interference) of weak current signal has great.
