3m 6650 - power supply & general opinion

[perleman]

Hi,

I've seen one of these for sale with no power supply...

Has any1 got the pinout schematic? Or any recomendations or complaints or comments about this unit

Thanks

[Video Freak]

do you have access of a pic of the power input/ panel? that may help in finding what it takes. PS wise

[perleman]

Hi, here is the only pic I can get. It is unclear whether it is a 5 pin din AT type socket. Working on pure assumption (and we all know what assumption is the mother of), I'd imagine it to be fairly likely to be an AT keyboard type socket as they are very standard

The dillema is whether to buy the panel with no power supply. If I could find out what is needed, I can probably build it myself, but if it's not possible to find out , then I won't buy it.

If anyone knows about this panel, I'd appreciate some comments - for example, if it's not very good then it'll save me the trouble!

Theres something about psu's in the good panel bad panel thread, heres the relevant part

Hi Acravero and all of you...

I am new to this forum but I have been messing around with LCD panels for a while. I will do a review of all of the ones I have in due course.
The power supply that I use for my Proxima Ovation panels is nothing more than a PC power supply with the cables hacked into. It was the
cheapest way I could find to get +5v +12v and -5v with sufficient amperage! The 5 pin DIN plug is obtained from radio shack, however,
I have been known to just stuff the wires in the holes. The great thing about PC power supplies is that they trip out when you short 'em!
Just turn it off and on and you are good to go again!

Looking at the side of your panel, from left to right in the semi circle of pins in the power input plug, connect the following from a PC power supply...

0v - Black / -5v - White / 0v - Black / +12volts - Yellow / +5v - Red


Check the power supply outputs if you are unsure whether it is a standard AT power supply. You will 99% of the time find that the color codings
are right no matter what manufacturer it came from

If you wanna get snazzy, buy an enclosure and some fairly heavy 5 core cable. Keyboard cables do NOT work, they will not carry sufficient
current to the panel even though it is tempting to use the connector.

I have found the best (read cheapest) source for PC power supplies is old computers in charity shops.

Have Fun!

PS Does anyone have the pinouts for an InFocus PowerView 950 power supply?

I know that for a different panel than the 3m but the socket looks the same, maybe the voltages are the same too? Seen that panel on ebay too but cant find out much about it, thats the chance you take i guess.

[Video Freak]

Freebie, thats the power supply for the proxima ovation, that could be substantially different then the 3m power supply. Hummm you cant get access to any more pictures? can you email the seller /buisness and ask them what the ps input looks like and what mabe it says on the back of the panel?

I know, I said it wasnt for the 3M, but a ive seen other panels that use +5, -5 and +12 so maybe this one does too.

[perleman]

I suppose the voltage might be written somewhere on the pcb, this is fairly common place - but it's taking a chance... I guess I was hoping that someone might actually have one and own a multimeter and be prepaired to give up a few mins for me!!! Or maybe someone's built there own already?

Thanks for all your help so far guys

Hey hope this helps, its for a 3M 6150, I got no clue on this stuff but should help u out, the manual says in the spec -

Power supply unit, 100-250 V~, 50-60Hz, 1.2A

Power Supply 7 pin DIN plug.

Hope this helps

I can add pics if u like

I think I have the high bid on this panel at the moment....I'm taking a chance that it will work with either a spare ovation PSU or spare infocus PSU that I have.... I think it uses a standard VGA cable for PC connection. If not, I will try and DIY a solution, or just re-auction the thing!!
The big worry for me is not finding the leads / PSU, but how many dead pixels the thing as!
I'm just wondering now how high the price will go - if it gets into 3 figures, you can count me out!

I bought one of your proxima panels (£195), but I also won an auction for a 3M 5300, just waiting for the seller to contact me re payment. Obviously the panel youre bidding on is a later version and higher spec than the 3m I won, but possibly the power supplies are the same. If you or pearlman end up winning the panel I could test the pin outs on that if youd like. I dont have a multi meter but I'm sure I could borrow one from somewhere. Again I'm assuming that the PSU's are the same, before someone points out the panels are different!! lol.
