I think a lot of people in countries which had been behind the iron curtain were not sad to see the back of their communist-era SECAM televisions. They were big, heavy, unreliable, clumsy things. In Poland, where I live, the Rubin 714p is such a set:

They had an annoying tendency to catch fire.
Basically, the locally-made sets were at least 20 years out of date and few people had colour ones. Even today, I've never seen an old communist-era colour set forgotten in a loft or garage. All the ones I've come across in relatives' houses, have been black and white.
The market was quickly flooded with relatively affordable imported multistandard sets which displaced the SECAM-era ones.
