Re: M43-C1 adding cooling fan
Any progress with adding the cooling fan? I just found an M43-C1 that had been thrown out by the neighbors. After a thorough cleaning, I tried plugging it in and I get no picture or sound, nothing from flashlight test, etc. The power LED flashes 12 times about every 90 seconds or so, but aside from that no signs of life. After reading about so many instances of this same problem, I took it apart to see what my board model number is, and I have an XFCB0QK003020Q board. I ordered a new one online so hopefully that will gain me a new 4K TV, but I'd rather not have to keep getting replacement boards as heat slowly kills them. I am familiar with this issue as I have a 2016 13" MacBook Pro with heat-related screen artifacts that apparently plague this model due to inadequate cooling design and a non-replaceable T-CON board that sits right up against the overloaded CPU heatsink. I want to avoid that type of thing with the TV if possible.Comment

Mounting and Handling Guidelines for TO220 TO220F TO247 Cases / Packages
The TO220, TO220F and TO247 are the popular packages for power devices because of their versatility and ability to dissipate moderate amounts of heat. This application note describes the basic guidelines for handling power MOSFETs in TO220, TO220 and TO247 packages shown in Figure 1. Please note that only mechanical and soldering guidelines are covered here. Additional precautions are required for isolating high voltage rated devices to meet safety regulations.

I hope my computer does not randomly reboot while typing this. My main system is the AsRock 970A-G/3.1 motherboard with the AMD 8150 chip. I am experiencing FREQUENT and RANDOM reboots once the system is used for a couple of hours (sometimes it reboots before I even get to the Win7/Linux Mint dual-boot screen). The problem MIGHT be the DRAM controller chip (I recently upgraded to the maximum 64 GB RAM). It also might be the VRM chips. I am using a typical aftermarket CPU cooler, which does NOT blow air DOWN onto the VRM heat sink.
(After previous generation hardware [Gigabyte] didn't... -
This is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
This is another battery testing machine that needs to be modified for the cooling fans because these are noisy but not as bad as one of the other battery testing machines that I had modified recently because of it being too noisy
The battery testing machine is going to get two temperatures controlled cooling fans like one I put in the other battery testing machine I just have to remove the temperature sensor and relocate the temperature sensor to one of the heat sinks and put one on the other heat sink so the fan speed can be controlled by temperature

When I first turned this battery testing machine the fan for the switching power supply was a little bit noisy but once I recapped the switching power supply board it quiet down considerably then I put a temperature controlled fan that does the mosfets control board was really noisy but now that it is cooled with temperature controlled fan that sensor was moved from the fan to the heat sink so now that the fan is controlled this way the fan runs according to the temperature of the heat sink
This switching power supply was really fun to recap the quality of the board was very good...
