he was checking for bad parts by connecting negative to ground (the casing) and going around the circuit board testing capacitors by pressing the positive on each side of a capacitor while set in continuity on a multi meter, if both sides are grounded or in continuity it means there is a short circuit within that capacitor
OK so to many of you Epson projector owners who's unit is bad, I'll save you some time. The main board does fail a lot. Just look on ebay to see the listings of dead units. I found 12 dead caps on my one and sent it away to be repaired but after all caps changed, unit still bad. They blow for a reason. This YT repair will work for about 5 minutes. You need to change the voltage switching texas Instruments chip and they're near impossible to find. Waste of time

I have a proxima desktop projector 9240 and the thing has no life.... no lights... nothing. It was turned off without turning other devices off first like described in manual and now has no signs of life. Does anyone know if this is fixable? Fuse or something?
