Hiii!!! I haven't been here for a while but i wanted to ask something

So I have this monitor from LG, it doesn't turn on and it seems it's something with the main board. I'm planning to give the board to my dad so he can resolder the port where you plug the power but that might or might not work so I'm looking at alternatives

The screen itself looks fine and is probably functional. I've heard that there are supposedly universal main boards for screens like this, so here goes my question. Is it possible at all to do this, if so then is it possible to do with my screen?

gonna attach pics here below with the monitors name, the port that it has etc.

cheers

woops uhh posted in the wrong category...?

This is most likely an LVDS connector. You should be able to find an LVDS driver board from AliExpress/eBay/etc. that will allow plugging an HDMI, etc. signal into it.

However, the LVDS driver board also usually handles the OSD and brightness/contrast controls, and that stuff might not fit your monitor out of the box. Depending on how much effort you want to put in, you can probably get something that does though.

thanks for that, I'll figure something out

https://pl.aliexpress.com/item/32807649 ... f2pihCjRJu so something like this should work? would i need something else to this?

I should preface this by saying I've never actually done a driver board swap myself (yet) so I recommend doing some research yourself to confirm.

I believe this should work. From what I can tell, your display has a 30-pin LVDS plug and so does that board. It's unclear whether it comes with a cable, but if not, you should be able to use something like this: https://www.aliexpress.us/item/2251832623454803.html (you can see how it would connect to both the board and your panel).

Also keep in mind this does not power the backlight, it only processes video input for display. It also doesn't provide a power supply; as the description says, you'll need to be able to give it 5V 1A from somewhere. Depending on the configuration of this monitor, you may already be able to preserve the original power supply to power the backlight, and get 5V 1A from it for the logic. If so, I think it should be a fairly drop-in replacement, but it will depend on the panel itself. It's possible the design might make this more complicated, but you'd have to inspect it yourself to see. You may be able to find a replacement backlight inverter board/power supply too, but that's definitely outside of my knowledge.

Good luck!

Thanks for the info! I might make an update in about a month or less since im busy and most of this stuff is coming from AliExpress and it has it's delivery times.
