@scifi76 this "darkish hazy horizontal band about 1/3 from the bottom of the screen." is not typical of a bad T-con board. Nor is a blown fuse. When any fuse blows, you get an all or nothing responds. Fuse blows = nothing works. The failure on your TV escalated over time and that is not typical of a bad fuse.
For now, I would suggest that you do not change anything. It can get expensive to replace a board that does not need to be replaced. We need to see your boards to find where some of the test points are. Post a pictures of the individual board as well as one that shows the complete setup of the back of your TV (cover off of course ;-)
I am not saying it is or it isn't the T-con board. It is just very unlikely to be the (only) issue. It could be the power board (unlikely) or the main board, Ribbon cables (check for tears and corrosion) and lastly the panel. Let's check it out and see if we can narrow it down.

BTW Philips is a bit of a PITA because their manuals etc. go by chassis number. The 55PUS6704 should actually be a 55PUS6704/12 and the chassis is a TPM19.6E LA

@scifi76 nothing obvious on the boards but some new , more focused images will definitely help. Here is a T-con board and just pointing to some of the test points we'll need to check on yours. There are some on the right side of the image that I cannot make out :-)

@scifi76 to check those test points, you have to reassemble your TV. Then turn it on. Using a multimeter, set it to VDC at a ~30V range. Black wire goes to ground. I usually use a screw head somewhere on the metal backing of the panel. Then use the Red probe to test the individual test points. Let us know what results you get from it. Since your TV is on, remember not touch anything with your bare hands. Stay away from the power board too since it will carry some decent current. It'll sting quite a bit when you make contact :-)

Check the fuse for voltage on both ends. That way we know it is working and don't have to switch your meter to continuity or Ohm mode.
