Hoping someone here can put me on the right track. I'm trying to troubleshoot/flowchart the "internal projector error" on my newly acquired Facebook Marketplace bought Epson 5040UB projector (3LED, not DLP). Owner said it needed new lamp, actually error code blink pattern indicates "Internal Projector Error, call Epson support". Unit is out of warranty as of 8/19
Here's what happens:
1) Power on
2) Blue power indicator lights and the lens cover motor opens the lens cover, light fan noise heard
3) Blue status light flashes for appx 4 minutes... -
Hi guys gooday i have a Epson VS250 Projector that turns on and is also being recognized and detected by the computer when i plug the hdmi cable.The only issue the projector lamp is not working .Are these lamps repairable ? Or i should just forget repairing the lamp and just buy a replacement. Thanks... -
Need some idea of where to start to fix this projector. According to the user manual, when the temp and lamp lights are flashing there is an internal problem which doesn't give me much to work with. Need some input. The fans run for like two seconds when attempting to turn on then goes straight to the error code. Since it's not a lamp, fan or temp error, I'm leaning towards the power supply.

hi all,
first of all: i'm a (motivated) newbie, so please forgive me any stupid question i may or may not ask
i'm currently repairing a projector: Epson EB-U42 that doesn't start (no lights, nothing).
what i've found so far:
- the PSU does its job and supplies 12V to the mainboard via the connector.
- shortly thereafter, there is a mosfet (TS420-600B) where i can test 12V on the one side (in the data sheet this side is called Anode), Gate 0V, Kathode shorted to ground
- not far away, there's the first cap with a resistance of 0.7 ohms....
