Hi, just giving a little update on this.
The CRT swap was a success! The picture is pretty bright and sharp! The other CRT was in fact worn out, (never seen that happen before) but then again I'm not a TV tech :P.
It was a really fun process, I also had to desolder the old H/V deflection wires from the yolk and resolder from the other CRT because the plug was different, I also reinstalled the degaussing coil and shield wiring from the old CRT. How fun!!!
Now the bad news, I ordered the IC, didn't notice there was a difference, the original is a TDA8361 and the ordered one was a TDA8361A I installed it and the flyback wouldn't fire. It did have audio and the volume worked, but in the end it was just an oversized radio.
I checked and double checked the pin soldering to make sure there was no short or bad connections, I also checked if I hadn't drop any solder on the board by accident but nothing.
So I reinstalled the old IC and it fired up again with the original symptom, of course.
I read on one site that the TDA8361A is retrocompatible with the TDA8361 but not the other way around but it doesn't seem to be the case. This time I ordered the correct part, I hope next time it will turn out better.
Since I'm fiddling with this thing, I also added a 3.58 MHz crystal, so now the TV also supports NTSC through the AV input :)
Here are some pics of what it looks like now:
