After previously adopting a big Sony Trinitron CRT TV that had been trying to hitch a ride along the side of a road in Italy for at least six years, [Happychoice] didn’t give up on trying to fix it, with the second part showing the TV being more or less fully fixed up.
In the first part of this mini-series, the TV had been salvaged and had most of the dirt as well as local flora and fauna evicted before an attempt was made to fix it. Unfortunately despite the insides looking remarkably clean and intact considering its use as a road-side ornament, that video ended with the controller refusing to power up due to issues with the power supply.
In this sequel we get to see what six years of weather exposure means in terms of what components to replace in a CRT TV like this. Unsurprisingly this means mostly replacing most of the capacitors, at least on the power supply board, as well as the neck board for the actual CRT. A couple of MOSFETs also tested open, so they were replaced too.
With those fresh new parts the TV fired right up again, and with a Wii console connected it looks pretty spiffy running games like Persona 4. Fortunately modern CRT TVs like these have a built-in service menu that you can access with the remote, so that you can tweak picture alignment and other settings without having to stick a screwdriver into the back of the TV to fiddle with a potentiometer whilst also keeping an eye on the picture.
Although there are undoubtedly more components on the PCBs and of course one grimy speaker to give some TLC, it does show that as long as the tube itself is intact, it’s definitely worth it to give repairing a shot.

That’s actually pretty incredible. I wonder what effect years of UV on the phosphor screen is.. or does that mostly get blocked out by coatings on the glass, etc? I assume the color isn’t the same as it used to be, would be interesting to try to color-calibrate it.
