Doubtful advertising descriptions like “Excessive Definition Digital Shade TV Driver Board” apart, this turned out to be a reasonably well-designed analog TV board. [Adrian] pulls a 20-year-old Magnavox ( Philips ) colour tv set from storage and begins the transplant operation. One fascinating remark is the Magnavox board has nearly the identical structure as the brand new board, aside from the orientation of the sections. The brand new CRT neck board had a distinct connector than the Magnavox set, however was designed to simply accept a number of sized sockets. [Adrian] simply eliminated the brand new socket and changed it with one from the previous set. The mechanical points had been a bit extra difficult, however nothing {that a} Dremel instrument and a little bit of scorching glue can’t repair. The 220 VAC energy provide was ultimately modified to simply accept 110 VAC, which additionally enabled him to reconnect the degaussing coil.
[Adrian] has collected some related documentation on this GitHub repository, together with schematics. Why hassle with this in any respect?
