Who used N.T.S.C 4.43

I had a frustrating problem with a customer several years ago... He brought in a Sony 20" multisystem TV with the complaint "no color". I fooled with it (no schematic available), and I couldn't figure out what was going on with it. It had PAL, SECAM, and NTSC. What I didn't notice at first was that the NTSC was 4.43 and no provision for NTSC with 3.58 mc color, which of course explains why no color. He had bought it in Zimbabwe, Africa while on a religious mission, and brought it home. He was told when he bought it that it would work in the USA, but sadly, no. So maybe some small African countries use 4.43?????

Zimbawe uses P.A.L. Problably is an "Sony" made for Europe, where we use both P.A.L. and SECAM. N.T.S.C. 4.43 is olnly for play-back mode.

I know heard of people from Romania who bought tv's from U.S.A. and after that found that they couldn't use them here...
