Recently, reporters from the city's quality of complaint reporting 12 365, the center of the complaints about the quality of the product set, especially some of the related standards, including the lack of national unity, LCD TV, which also guarantees restriction policy for the treatment of claims brought difficulties.
R: the approach of "standard" as a
discovery Reporter most of the reporting of quality television always leave "standard" two characters. Due to the lack of the rule, there are no conflicts television smell, the current color LCD screen existing crack shell leaks. What is noteworthy, rilliant screen "in the allowable standard really affect the consumer to use the issue prominently.
Experts say, cause a bad television can have many aspects of transformer intensity of factors, including the problem, grounding line, humidity, leakage current circuit, shielding signal input, the contact is bad, the design congenital or a circuit fault, so it needs through professional inspection will be confirmed. While rilliant screen is actually are related standards, with plasma screen can appear on the LCD panel, why not shine defects and have not extinguish unless specific provision.
"It does not smell" for television too common, the "peculiar smell, mainly due to the new" appear overheated circuit after chemical or plastic smell. Phenolic compounds in the board, through heating, and housing will be adding volatile plastic additives is difficult.
