This kind of fault is very common, usually burn insurance or voltage regulator chip failure, some of the machine is the built-in switching power supply, output two sets of power, one set is 5V for signal processing, the other set is 12V to provide high voltage For backlighting on the board, if there is a fault in the circuit of the switching power supply, it may result in no output of both sets of power supplies.
Another possibility is that the 5V load is getting heavier, and the 5V voltage is pulled very low. In other words, the signal processing circuit in the rear stage has a problem, some of the circuits are damaged, causing the load to increase, and the 5V voltage is pulled. Very low, one by one after the investigation of the problem of the components of the latter stage, after replacing the faulty components, 5V can be restored, the fault is generally resolved, and often encountered after 5V voltage recovery is not a good boot.
There are many reasons for this situation. On the one hand, the MCU program may be flushed, which may result in no boot, and the MCU itself is damaged. For example, the I/O port of the MCU is damaged and the MCU cannot scan the keys. Faults caused by the MCU, find the hardware problem is useless, even if you change the MCU can not solve the problem, because the MCU is the need to program and write the Ma, in the case of no way to find the original AD driver board replacement, We can only find another way to find the A/D driver board that can be replaced. There are many places on the market that can be purchased. If the local market can't buy it, you can post it on the LCD home forum. Many LCD masters may be able to purchase the accessories you need and find the information you need.
Characteristics and Advantages
(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;
(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.
(3) Anti-clamping function: automatically reverse when meeting barriers;
(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)
(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;
(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;
(7) Bi-doors inter-locking: one of the door leaves always remains closing;
(8)Safety sensor terminal: sensor stops working when door closed;
(9)Unique coating technology: never rusty;
(10)Easy and convenient to install;
(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Details:
(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;
(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;
(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.
(4)Feet sensor switch applied to avoid contagion;
