The light is on, the fan doesn't turn, the projection light doesn't work. Where is the trouble? Thank you
Only small factories in China are now trying to fool amateurs online!!!And now the price of 3000 yuan brightness of 3200 lumens world famous projector, bulb life has reached 10 thousand hours,10 thousand hours later, the brightness is still about 2000 lumens, or far from spike any new LED pole, nut cottage projector!!!!Domestic copycat machine: nuts, rice, advertising than hongtianpao more crazy!!! But the brightness is low, but it's actually less than 500 lumens!!! Also posing as an international standard of 3750 lumens!!!Obviously only a few hundred lumens, why should deceive consumers?!!!!! Quality is very bad, less than a year bad!!! And the price is as high as 5000 to 7000 yuan, it's just killing people!!!!
The price of replacing LED lamp assembly is more than 700 yuan!!!More expensive than SONY, Panasonic projectors, and high brightness bulbs!!!LED projection if there are really so good, why is Japan's SONY, Matsushita, EPSON, Hitachi, Toshiba, SHARP not to do!!???LED projection technology is the most advanced in japan!!!Why is the world's first projection technology Japanese do, Chinese brand BenQ will not do, this is the Chinese copycat small factory to make waves!!! You should understand, this inside is completely the domestic copycat's deceit method!!!Why can't the computer store basically see LED projector sales? Just selling on the Internet? Why???Because the effect is bad, can only deceive the layman on the Internet, consumers do not understand!!!Domestic LED light source projector brightness is too low, most only 200--500 lumens, technical content is very low, is not what the use of copycat goods, value, effect is very poor, some products are even sold 6999 yuan price is more expensive than Japan SONY, Matsushita, is completely rely on online bragging, drawing effect and not resort to deceit deceive serious knowledgeable the people,Few entities dare to sell such projectors because the images are too gray to be seen and turned off at night,There is no way to test the entity shop, because the brightness of LED projection is too low to see clearly, and the quality is too bad, the failure rate is high!!!The United States, Japan, South Korea, Chinese BenQ, Acer is fully capable of mass production of LED projector, LED projector, but because the brightness is too low, life is too short, 2 thousand hours of brightness fell sharply, not what the actual use value before mass production, now still in the laboratory research stage,
Motherboard damaged, this cottage machine quality is very poor, and later to buy real brand-name, such as BenQ, SONY, EPSON, good quality, with 10 years no problem, the effect of killing 1000000000 times the cottage machine!!The LED projector is completely rely on money [figure effect online bragging serious resort to deceit.]Why is the domestically produced LED projector only a short span of 1 years warranty?If the LED projector really lives long, why is the warranty only half the size of the brand-name product?Why is Japan's SONY, Matsushita, EPSON, Hitachi, BenQ Chinese, Acer projector is the world famous 2 year warranty,And domestic LED projector only a short 1 years warranty, and if the LED projector really long life, why is the warranty only half of brand-name products?Because of the poor quality of the actual domestic LED projector, low brightness is not clear, the failure rate is too high, not mature technology, poor quality parts, backward production facilities, backward technology, these small manufacturers did not dare 2 year warranty!!!These fully show that domestic LED projector small factory is very timid, very guilty, and no confidence in their products!!!Nuts, rice, the actual life of hongtianpao and so on all kinds of domestic LED projector 2000 to 3000 hours *************Nuts, rice, real life hongtianpao LED projector and so on 2000 to 3000 hours later, LED lights use 2000 to 3000 hours, the brightness will drop rapidly, absolutely not up to what tens of thousands of hours!!!
