I wouldn't know the first thing about programing it.  I suppose I could mail them the LCD.  I'll wait and see what they say.

LOL.  I did meant you to write "code". 

I meant you to buy the electronic device that is used to program your device which would presumably come with a series of files and then try to program/flash different files until one works.

Well, hum..  a "programmer".  Tongue    I do not even know if they sell it or what.  I think you have to contact them and tell them about your issue and discuss the options.  The best is of course to send them your panel so they can make sure it works before sending the kit back.  Probably you would only need to send the main board and the cable along with the LCD (no need to send the power supply).

Editted.

I can see the backlight is connected to the tcon board attached to the tft, so if the lights come on this is connected correctly. Are all connectors seated properly?

What you might be able to try is connecting the panel to a computer as a second screen and downloading a freeware EDID application, this will tell you what settings the lvds have programmed. The EDID info contains supported resolutions including optimum resolution, product details, manufacturer details ( that is the manufacturer that the lvds was programmed for ), and product type, from all this you might be able to ascertain if the lvds is correctly programmed for your screen.

The back light is coming on, I am pretty sure of that. 

I can run the program on my laptop since it uses the same monitor.

EDID Viewer shows two monitors, not sure if one is something I plugged in once long ago and it saved the info, so I will post both.

BOE vs. SEC manufacturer. Which one matches better?

It does say BOE-Hydis on the label.  Although my monitor calibration software thinks it's a Samsung, and lots of websites claim it is supposed to be a Samsung.

The Hydis screen is the top one. I've taken screen shots of the edid info in the datasheet for you panel to compare to what you have recorded (see below), first glance looks like a match, but i don't have time to check they match thoroughly.


* Hynis EDID 1.jpg (199 KB. 720x1280 - viewed 301 times.)



* Hynis EDID 2.jpg (205.52 KB. 720x1280 - viewed 268 times.)



Doh, just spotted my spelling mistake in the filename, it should be hydis not hynis.

So I heard back from the seller.  It isn't quite clear but he makes it sound like if I trace the red lines coming from the side with the white dot, they should go into the left side of the screen connector.  Well if that is true then I've had that plug in backwards this whole time.

Please kindly check that there are two images. One is connected to the controller board while the other one is connected to the laptop screen. However, the one i remarked as red on your screen is the power cable. You have to align the white spot side of the cable. Please kindly let us know if you have any other questions and we are more than willing to assist you any further.

Also if true it still doesn't work.  I think I need to get a new cable so I can hook it back up to my laptop and make sure the stupid thing still works before I move forward with anything.

What did you connect backward? like they say, follow the power lines. They must connect (test them for connectivity to be sure while the cable is unconnected).   Then connect the LVDS side, check for voltage levels on the power side pins (at the other end of the cable).

hope that make sense.  Tongue  difficult to explain

If I am understanding them correctly, then they are telling me the wires coming from the circle on the plug are the power wires, and that the power wires should line up with the circle they have placed over my photo on the LCD screen.  Problem is, the plug went in easier the other way around, so all of my tests with it have been with the LCD end of the plug being backwards.  I have since flipped it, and though it took some work I got it plugged in.  The LCD back light comes on, but the screen is mostly black with colored lines on both sides.  I don't know if it's a programing issue or if having the plug in backwards has ruined the LCD.  If I can get another cable to connect my LCD back up to my laptop then I can check to see if the LCD still works.
