We have seven or eight of these Shimian QH270-Lite monitors in the building. So far only one unit has arrived with any dead pixels (it had 3). This week we ordered a couple more and one had a cold solder joint. It would power on but never get a signal. The LG panel was solid and the ribbons were all in good shape... However, there was something fishy with the PCB.
This video is really rough, so we do apologize about the audio and video quality. It was unplanned, but I thought everyone would enjoy watching us bake the PCB. Also, this video will give you a good look under the hood so you can see what goes into the Shimian QH270-Lite.
In the end, we did fix the monitor! Let us know what you think.
