Hi guys
I have a Technika 22inch tv that has an annoying flicker in the upper corner of the screen. I have figured out that one of the backlight strips is almost gone and is on its last stretch. This tv has 4 back light strips and I will still be able to use it with the other 3 backlights. The problem is the flicker as it is very difficult to watch/play with it.
The inverter ( LK-IN220413) has 4 connections to the backlight strips. If I remove any one of them, the onboard mosfet detects it as a fault and switches off the entire backlight to protect the tv. A youtuber called MrReeceyburger123 produced a very nice video on the topic for this particular tv where he desolders a certain capacitor that prevents the board from switching off the backlight (link below)

Unfortunately my tv uses a slightly different inverter board and with substantially more capacitors/mosfets on it. As I do not wish to randomly remove pieces of the board without knowing what is what, I wanted to ask you guys if you have any suggestions or guidelines on how to proceed.
I can provide images of the board and part numbers but I cannot find anything useful on the internet about this circuit board apart from where to buy a new one.
