In this video, I will share my experience on how to repair a 42-inch LG LED TV. to be precise tupe 42LN5100 which suffered total death damage. so to be precise this tv was damaged when turned on the indicator light only flashed once, without any subsequent flashes. which indicates that the tv is not booting and starting on. so first I took measurements on the PSU unit and the psu pin out, it turned out that the voltage was normal, no problematic voltage was found. and this is proof that the mainboard tv is not working normally. this is most likely caused by a damaged ic chipset used, namely the LGE6841. This chipset damage is often found on this type of tv, so I did the right proof by heating the chipset body with a steam soldering iron or lighter, until the chipset body temperature was hot. then I tried to turn on the tv ... and it was proven that the tv instantly started on and displayed images normally. but keep in mind that this condition will not last long, where later after the tv is turned off and turned on again in a built condition, the tv will definitely recur with the symptoms of the case as before. Therefore, it is necessary to take appropriate action by replacing the IC chipset, or better yet, replacing one unit of the mainboard module. that way the tv should be back to normal. that's the content for this video, hopefully it will be useful for all of us. Thank you.
