Authentication case
A shopping mall purchased an LCD TV and received a complaint from a customer half a month later that the screen of the TV was cracked. The manufacturer said it had nothing to do with quality and did not agree to compensate. Later, it went to court. Under the entrustment of the court, our company identified the cause of the cracked screen of the LCD TV involved in the case.
The expert group tested according to the indicators specified in the national standard GB/T 17841-2008 "Semi-tempered glass", and tested the stress of the screen of the "LCD TV" involved. By analyzing its cracks and explosion points, and summarizing the expert opinions, they came to an appraisal opinion: the cracked screen of the "LCD TV" involved was caused by external force.
