leisure 3 projector turns on for a second, the fan spins, then it just shuts off. no light, nothing.
This is a classic overheating or power failure symptom. The projector goes through its startup check, detects a problem (usually related to temperatu…
-
why is the movie i'm streaming from my phone to the leisure 3 so choppy and laggy?
This is almost always a WiFi issue, not a problem with the projector's processing. The screen mirroring function (Miracast/AirPlay) requires a very s…
-
hdmi port on my vankyo feels loose and the picture cuts in and out, did i break it?
You probably didn't break the port itself. The HDMI port on these projectors isn't the most robust, and a loose connection is often caused by the wei…
-
i see a weird dark shadow or blob in the corner of the picture from my leisure 3, like a smudge on the lens but it won't wipe off.
That's not a smudge on the outside lens. What you're seeing is either dust or a tiny fiber that has gotten inside the projector and has settled on th…
-
my remote for the vankyo projector stopped working completely, do i need a new one?
It's almost never the remote itself that's broken. The first thing to check is the battery, but the second, more common issue is the remote's IR sign…

the fan in my leisure 3w is ridiculously loud, sounds like a jet engine, is this normal?
It's definitely not supposed to be a jet engine. The most likely cause is the projector's air vents are blocked or it's sitting on a surface that's t…
-
just got my vankyo leisure 3 and the picture is super blurry no matter how i focus the lens, what gives?

my hisense pl1 projector won't turn on at all, no lights or anything, it's just completely dead.
You've got a classic no-power situation. The most likely culprit is a fault in the power supply circuit or a completely failed internal fuse. First, …
-
the fan on my cinebeam is crazy loud all of a sudden, like it's running at full speed even when the picture is dark.
The projector's internal temperature sensor thinks it's overheating, so it's commanding the cooling fan to run at maximum RPM to try to save the lase…

i see a weird dark shadow or blurry spot in the corner of the image from my lg projector. it doesn't go away.
That's likely a piece of dust or debris that has settled on the internal lens or, more seriously, on the surface of the DLP chip inside the sealed op…

-
lg pu700r making a high-pitched whining or buzzing noise, seems to be coming from the lens area. is this normal?
You're likely hearing the laser diode driver or the color wheel spinning at high speed. A faint, steady whir is normal, but a pronounced, high-pitche…

my new lg cinebeam pu700r won't turn on at all, the power button light just blinks red a few times and then nothing.

my px701-4k projector is making a loud grinding or whining noise from the fan area, it's way louder than normal
This is fan noise. The most common cause is dust accumulation on the intake filter or inside the projector, forcing the fan to work harder. A less co…
