Hi folks,

I'll be buying a Sharp QA-2500 without manual or power supply. I know the Sharp uses a 4-pin power plug, but I don't know the voltage the unit needs nor the pin-out arrangement. Does anyone have a source for power supplies that would work? (I have not yet called Sharp). Is the Sharp power supply compatable with other panels?

This forum has been a great source of information as I get myself up to speed on DIY projectors.

I think that infact the Sharp QA-2500 has the same power requirements as the QA-1200, in which case it is not a 4-pin plug but needs only a power supply delivering 12 volts and a minimum of 1.9 amps using a standard connector (polarity: barrel is ground and the internal pin is the +12v supply).

This can be made from an old AT power supply or bought pretty cheaply from electronics shops such as radio shack in the US or online in the Uk from www.cpc.co.uk!

Hope that helps, Rich

Just realised I'm completely wrong and yes the QA-2500 does have a 4-pin plug. However, as requirements are +5V at 2.8 amps and +12v at 1.8 amps you can still make the power suplly from an old AT PC power supply, though you'll need to find out which pins are for what!

I once looked into buying such a panel. I actually called Sharp, who then referred me to another company, that sold the original power supplies. I believe they were $175 a pop! The remote was the same price.

So.... if you are looking for an expensive, official, alternative....

Power supply/VGA cable pinout diagram?

I just bought a 2500 as well w/o any cables and was just wondering where I could get them without selling 5 or 6 pints of blood... Well, ask and ye shall recieve! 😀

If one of you can provide even a rough diagram of what pin carries what voltage etc out of the power supply, that would be great, then we can fab up our own power supplies.

Also, I'm going to get a power supply from a 1650 - does anybody know if that will work AND does this thing have a propriatary cable, or will any ol' VGA cable serve to hook it to a computer AND does it need a remote to function or is that just a nice thing to have if possible?

Thanks in advance,

Dave

Hey guys,

I know electronics don't like volts, but can you damage them if you don't give them too few or too many amps? :scratch:

The reason I'm asking is that I have an old PC power supply that should give me 12 and 5V but I'm not sure what the amp rating will be.
