Hi…Some more up to date Samsung LED-LCDs and LCDs with 240Hz processor have separate tests for FRC (movement upconverter/T-con) and principle board from administration menu, yet no entrance if TV will not catalyst and menus aren’t usable.

@gbarranco Any monitor will work that has HDMI input. Here’s the trick though. if you’re gonna put it in/on a wall, use a monitor that has it’s ports pointing down, not out of the back. Make sure if you’re going to put it behind mirror glass that it’s flat - you don’t want a curve on it so it can sit flat against your external glass.

I personally use a monitor like this one: https://www.amazon.com/Dell-Ultrasharp-U2719DX-2560x1440-Resolution/dp/B07KGR784M/ref=sr_1_4?dchild=1&keywords=edge+to+edge+monitor&qid=1615315119&sr=8-4

Notice how the image is edge to edge, that way I can take off the frame and have almost all the monitor used.

Hi greeting everyone,
Can someone give suggestions which universal controller board kits I should buy for my LG TV.

You can use any universal LCD controller board that supports 30 pin LVDS 2 channel, 8 bit. (FIX-30P-DO8L). Make sure you get the right LVDS cable with it. You can use the black GND wires for fingerprinting to make sure they fit your screen.

You’ll also need an inverter with 4 ports for the CCFL backlight.

The cheapest set should be around 3€, more advanced (TV controller)boards with HDMI you get for around 10€. Boards with a firmware dedicated to you screen cost around 30€.

This is a really good site to start collecting information about LCDs.

At this point it’s really hard to troubleshoot from the distance.
Of course it’s possible that either the board or the panel is broken. I suppose the menu isn’t displaying either?

Have you made sure you loaded the correct firmware onto the board? You should be able to try any firmware which fits your resolution plus 1-ch 8-bit (iirc, check yourself please).
