Re: TO-220 job help?
Maybe look into the service menu again and see if you can find a name with the tuner. Sometimes you can select tuners, sometimes there is a specific firmware for tuner x, etc.
Other than that, flick through all the service settings and write them down / take a photo and then to a factory reset everything.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.

Well, my Gateway monitor seems to eat caps. So I was thinking there was some systemic issue going on here and what I'm thinking: the heatsink is blocking convection flow and thus roasts capacitors by radiation!
Now what I wonder. This piece of aluminum heatsink is obviously blocking convective flow. I could add a fan but there are some other issues involved here. How about...drilling holes into the aluminum?
The holes would add surface area and allow air to convectively flow through the heatsink which could reduce temperatures. However this would of course reduce the... -
Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.
Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting...
