Hardware failure: black screen of large screen system, jitter and various unstable phenomena, image splash, splash, dot, insufficient brightness, color distortion, screen dislocation, gap adjustment;
Or, let the maintenance master directly check the situation:
Software debugging: adjust the brightness, contrast, grating and color of the large screen system, restore the initial value, correct the image trapezoid, and adjust horizontally and vertically;
Circuit maintenance: DMD board maintenance, RGB board maintenance, power board maintenance, signal board maintenance, lighting starter maintenance, interface maintenance;
Optical path maintenance: light source, color wheel, optical channel, lens, reflector, refractor and lens;
Replacement accessories: bulb consumables, heat dissipation accessories, light path accessories, circuit accessories, DLP equipment;
Large screen processor; Replace the processing board, repair the power module and restore the large screen processing system;
Large screen maintenance: circuit reinforcement, optical channel detection, cooling channel cleaning, screen cleaning;
Six-axis adjustment: professional six-axis optical adjustment mechanism, fast and fine adjustment of image geometry, high stability, to ensure seamless splicing of images.
The equipment of the projection unit is treated with dust prevention/heat dissipation, and the service life of the equipment is extended by IP5X protection treatment, so that the mean time between failures reaches the longest MTBF.
Generally, the master who has done maintenance for many years knows this better, so you can consult and ask. You can also find many Baidu maps in Shijiazhuang.
