Not litterally on fire, but is smells very bad and was hot to touch, of course didn't work at all anymore...im returning it. But how?
im so disappointed...at this point im just waiting for the d30pro and a30pro...only possible upgrade now!
After a period of research and discovery of the specific causes of equipment failure or damage, we generally determined that strong static electricity is the culprit.Especially in some dry air in the region will appear the probability of failure will be higher.
We tested it in different areas:
In northern China, such as Beijing, the air is dry and static is strong.
In southern China, such as Shenzhen, the air is humid and there is almost no static electricity.
Running LA-QXD1 alone for long periods of time means that LA-QXD1 is not in contact with any other devices, especially metal devices, and LA-QXD1 in this case can be understood as an electrostatic collector. In dry air areas, LA-QXD1 runs for a period of time (ranging from a few days to a dozen days), if there is human contact (hand), it may lead to high voltage electrostatic spark, thereby damaging the unit. This is one of the mechanisms by which we found the unit to be damaged.
In other cases, LA-QXD1 was run without corresponding damage. There are several effective ways to avoid this problem:
1) If it is an already purchased user and the local air drying has high static electricity, we suggest that LA-QXD1 contact the metal surface of other surrounding equipment to help prevent static electricity;
2) For newly purchased users, we have optimized and tested the ex-factory PCBA and the casing for a long time, but nothing similar happened, which proves that my optimization method is effective and subsequent shipped machines are optimized. Optimized units have no impact on performance and can be safely used.
The above problem has been confusing me, SONCOZ was in South China's Shenzhen, our laboratory test all didn't test the electrostatic problem, until one day my user in Beijing (north China, the air is very dry) suggested that I might be the electrostatic problem.Then we started a series of tests and finally identified the problem and found the optimal solution.
The SONCOZ will always be the company that accepted the user's opinions, optimized the product and promoted the user experience. Thank you for your support.
