Hello,
my current remote for the SAnyo is very problematic, i can turn the device off but not on. So i figured lets look into a universal remote to handle this and a few other things in the conference room. i just don't know if this will work or not. any suggestions?
thank you

Sanyo has published the IR codes for this projector.  I can't easily turn the Google result into a link, but the projector uses NEC1 device 51.0.  Anyway, the main point is that the Power is a toggle, and the remote should send the same signal to turn it off or on.  Since that apparently doesn't work, we need a clearer explanation from you.

What remote are "currently" using?  The Sanyo remote that came with the projector?  A "Logoitech"? A Logitech?  Do any other functions work?  

If your current remote is a universal, did you learn the IR signals from the OEM remote, or are they from a library?

Hello,
We are using the remote that came with the projector. All functions and commands on the remote work except the power "on".

I doubt that the remote is the problem.  The On/Off button should send the same signal every time it is pressed.  Oddly, the manual on page 8 says: "You can only turn the projector on/off with ON/STAND-BY button on the projector."  Page 15 says that the remote can also turn it on, as we certainly would expect.

Page 17 shows an on screeen display that has a menu item "Advanced".  Perhaps there is some kind of power option buried there.  

As with most projectors, the unit will not turn on until it has cooled some from previously being on.  

I'll check the advanced menu, but this thing was off overnight so it is definately not overheating.

looked at the advanced section and made a few adjustments but no luck. Its odd when the projector is going down from being on for a few minutes i can turn it on (blinking blue light) but as soon as its off (red light) i can't turn it on.

Page 15 of the manual says: "1.  Ensure that the power cable and signal cable are securely connected. The POWER LED will turn red."  It also says (later on) that the red LED will light again when it goes back into Standby from On.

If the power cord is connected, and the projector doesn't show a red LED, I'd guess that it is not in Standby mode, but Off, which presumably means that it isn't able to listen to the remote.  Maybe time to contact Sanyo?

I'm sorry i may have mistyped that. The unit is off or standby with a red light then i try to turn it on but with no luck.

I have the same problem with projector SANYO PDG-DSU30. My projector cannot turn on using the remote, i need to push the button manually. But, after the projector ON I can use the remote.

It's a $400 projector. They cut a few corners to get the price that low. Unfortunatly for you, it looks like one of the corners they cut was to remove the IR receiver on-in-standby mode. That means that the IR "eye" is shut off when the unit goes into standby mode.
