What is the problem here, do they run too hot or just poor quality? Perhaps I could add a small heat sink (using thermal glue) if it's a heat problem. I haven't worked on one with a regulator problem in some time but I have an eye on one that may have the problem.

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.

Hi all:
I have a Vizio E60-E3 I am trying to troubleshoot a no power problem with. Thanks to the help on this board and elsewhere, I was pretty sure I had narrowed it to a power board problem. The board in question is a 09-60CAP0D0-00. Image attached for reference, but not of my board (tv is put away at the moment). FWIW, no obvious looking issues with the board.
I measured voltage at power in and on the fuse and saw 120V, so power is getting to the board.
On the pins out to the main board, I got no voltage at all on any of the pins. I assumed this... -
I have an LG Plasma TV 60PM6700 for the past ~12 years.
In the last ~3-4 months I have been having some issues.- Problem: It started with random picture disappearing (sound still worked).
Frequency: Happened about once a week.
Solution: Had to turn off TV wait a few seconds before turning it on again. - Problem: Then it got worse and the TV started to shut down and when turning on the no picture just sound.
Frequency: Happened about once a week.
Solution: Had to turn off TV wait about 10-20 seconds and turn it on again to solve. - Problem: TV shuts down
- Problem: It started with random picture disappearing (sound still worked).

i have a problem with thinkpad X1 carbon gen 2 "LMQ-1MB 12298-2 48.4LY26.021"
The laptop was turned off because the MOSFET was not transmitting voltage. After checking it turned out that the gate pin on the MOSFET was the problem, because it was producing an inappropriate voltage. and it was discovered that the problem was with the Think engine, so I decided to reprint each pin, and finally the mosfet could work properly. However, there is another problem, even though the voltage has been supplied to the laptop, it still won't turn on, there isn't even an LED indicator. After double... -
I have a M60-C3 where the left edge has started showing issues as seen in the picture attached. Along with this, I also noticed some darkening on the left half of the screen which went away after I left the TV unplugged. i initially thought it was the led backlight that was wearing out but looks like something to do w the TCONN board. I searched this forum but couldn't find anyone else seeing this issue. most of them were LH/RH completely gone. any insights or guidance is appreciated.
Here's a video of both the issues: https://youtu.be/hMqc760nB3o
