What is the problem that the LED light in the living room is half bright and generally not lit

The living room lamp drive is generally not rotten, basically the lamp beads are rotten, which should be connected in series, so the rotten one will affect that group + build a stool + check carefully + whether there is a lamp bead burned + the naked eye can basically see the gold wire burned off and blackened + a small black spot + as long as there is a black spot is burned + multiple light strip series circuits are generally burned several + the whole half (half is generally 5-6 light strips will not light up, and the living room headlights are generally controlled by two groups of ballasts + so only half is not lit).

The voltage required for LED lights is particularly low, so the emitters are connected in series, so one is broken and the other is not lit.

There is a tail plug at the end of both sides, which allows the circuit to form a loop, and see if there is less end on the side that is not bright. If it is good to try the light bar again, then try the driver and plug the non-lit end to the bright end to see.

I don't know how many drivers you have in this lamp, from the fault phenomenon it looks like it is caused by poor contact, it is recommended to check all the lines to see if there is any bad contact, reconnect it, open the driver, and see if the circuit board inside is warped or broken. Re-weld.

The living room LED crystal lamp light strip is half on and half is not on, indicating that it is two groups of series circuits, possible causes and solutions: >>>More
