Question about Boxlight CP 19t Multimedia Projector
The projector powers up normally and displays image for less than 30 seconds and then shuts down just like it was powered down. After the normal power down cycle the green light comes back on as if it were properly shut down. I called Boxlight and they thought it was either the power supply or main board. Can you confirm this and can I get parts to repair it myself if it is a board replacement or component repair? To send it in for repair is too expensive. I am a tech so I don't mind working on it if we can salvage it for a backup. Any suggestions?
It is the power supply/ballast. when you first turn it on, the caps on the ps/bal charge then discharge when the lamp is to strike. if the caps are dried out (from excessive heat), it takes a while to build a charge. so the power drain from striking the lamp brings the ps/bal into shutdown. after you try again, the caps are now up to full power and everything is fine. but every time you unplug it, you'll have the same problem. replace the power supply and ballast.
