Read ALL instructions. Connected panel, correct polarity. Panel output at 15 - 21.5 V, 2.0 Amps. NO DISPLAY! HELP!

I had similar problem until I hook it up to a battery. After that all is working fine for me. I also found that it won't work properly if the polarity isn't right. Double check that, as I went over and over mine and found I wasn't right. Also when you are checking all connections undue all connections to reset the controller and all will work fine if all the right connections are made. I've had mine working for about 6 months.

Thanks so much for your response. I'll go ahead and bust it out of the package and try it out. Trying to connect an extra monitor!! Lee

Check for loose wiring/loose fittings first. Second would be to try changing the resolution on screen. Last would be your monitor is going out. Let's hope that's not it.

I am sorry mine just worked instantly. Make sure you have it well connected and did not damage any pins. Maybe it is more than the display sorry

Please check all the connections and replace with a new power supply. If the problem remains please send it back.Thanks!

I just checked the monitor and its box but neither state how much amperage it consumes. Use the 12V@3A power supply. It should handle the monitor just fine.

Mine works fine, but remember you have to separately plug it into the appropriate pins on your motherboard, if you did that and it still does not light, reverse the leads and try that. You would think that polarity does not matter but we've found out in this case it does. Also, don't pay the current price showing here of $84, I bought mine on sale from Amazon back in January for $49 including a $10 rebate, but for instance right now at New Egg this same case is on sale for $59 with rebate

Have a look at the back of your power brick (you may need magnifier, I do), it will have an output value saying ___ VDC. If that is 12 or 19 then you should be good to go.

This panel is a 60 cell module (Vmp = 30.1v). You will need 2 x 250w in series to make close to ~60v output, and 4 x 250 in series to make close to ~120v output.

I have this same problem. Do I need to replace the main circuit board or the display board. I can get all readings, just no lighted buttons such as power, generating etc.

I think you have a dud---DOA. Mine worked as a "plug and play." Sorry I can not be more helpful.

There should be 2 VGA ports IIRC and an HDMI. Try it with a different monitor too!!

Send in for a new one...really! Or you could try to fix it by buying new boards; it is not the back light or power supply.

Did you do a complete reset? There is a small hole that you can stick a pin in to reset. That would be the only thing that I would know of. Have you tried plugging into port to see if hard wiring works?

ac-dc inverter board ... order it through mcm electronics... open up the monitor and find the board that looks like it when you receive it, and simply swap it out.

A multimeter shows the V+s are internally shorted as are the COM terminals, though I haven't tried running a 20A load through a single terminal or splitting it.

Sunny-If your source has HDMI output but no display port or DVI output, just get an adapter. They are available and reasonably priced on Amazon.Jim
