I'd also be curious to hear from other that have worked with these.
I've got an older 50" Changhong tv that had a failed controller board. I purchased two different universal controllers and haven't been able to get it to work yet. I suspect the problem is with selecting the proper LVDS cable, since there seems to be several standards.

There are quite a few videos on youtube of various individuals demonstrating how to use them. Typically it looks like after getting the proper LVDS->Panel connector, you have to flash the board with the proper firmware for the resolution and driving voltage of the panel, and then some minor tweaking with the remote after entering a service mode, so make sure whatever you get has the controller board and/or a remote with it.

Thanks for the input.

Yes, flashing it, and getting the firmware right will be the tricky part.
Otherwise, will get a larger monitor that has a known converter will be the way to go.

WHat's the make/model of the display - would be easier to find a driver board that will work if you have that info. ( should be able to contact one of the sellers on ebay etc. that sells driver boards and ask them which one would work with the model panel you have)

I buy MT6820-B and/or MT561-B LVDS boards to replace toasted ones in 19 inch ELO monitors for touchtunes jukeboxes. they are almost plug and play except for repinning the power cable to swap the +5 and ground wires and swapping the connector for the menu buttons.

I have used them 2 times in the generaltouch touchtunes monitors, but I have to install a buck converter to change the 12v to 5v to run the LVDS. i suppose i could find a different straight up 12v capable one, but it doesn't come up very often and i usually have a buck converter i can use laying around.

most of the 19 inch and up panels use the standard LVDS connector, but some of the 17 inch panels and 15 inch panels use a PIN connector instead of an EDGE connector and is not compatible with the ones supplied in the kits you get off ebay etc.

i've never had a problem with a panel not working with them. you can usually type the panel number into google and get a info sheet that tells you the resolution bitrates and stuff you need to set the LVDS to. some LVDS need to be programmed from the seller, others are dip/jumper configurable. if it's the latter, be sure to supply your seller with this info so it gets programmed correctly. be warned... a single letter difference (1234-AC vs 1234-ACB vs 1234-A) can be a huge difference in panels so be sure to double check before sending off your order.

ahh, that's basically a 12 volt version of the ones I use... with also a separate VGA ribbon cable instead of attached VGA. I'll have to snag a couple of those for when I have to do general touch monitors.
