Dear all benq w5700/ht5550 user, firstly please apologize my poor english.
I bought w5700 in thailand back in december last year. it is my second projector (upgrade from w1070). during initial use I saw a bright pixel at the right edge of the screen which did not bother me too much since it is outside of frame. so I let it be not much concern.
But after two months during mid February, I started experiencing anormaly behavior like attach link to youtube video below. The w5700 frequently freez in a middle of nowhere on occation events. sometime quite often like every few minutes while another time hours.
I extensively ran many test to find the source of problem by change 2 players (PC and apple tv), 3 hdmi cable, 2 avr hdmi inputs, 2 avr hdmi outputs, 2 benq w5700 hdmi inputs and finally connect the player directly to the benq. Finally my conclusion was benq w5700 hdmi 1 input cause the problem. I always turn off every equiptments before plug and unplug everythings.
Then the dark pixel suddenly appear in a middle of the screen like this.
I contact the store I bought w5700 from they took it back and inform me today that benq thailand are going to fix it within two weeks.
fix it not replacing it, I don't happy with this but don't know how the replacement policy on those bad pixels on projector. and one more trouble on hdmi 1.
I thing the bad pixels warranty policy should be the same across the globe.
how does benq react to defect like this in another countries? anybody having experience like this? please let me know.
