The problem is that the major name brand products fix their design issues .The failed designs end up in a Chinese copy factory and they are churned out by the millions under various brand names.
It does not help that the EMC laws are not enforced at the borders, they just accept the fraudulent EMC markings from the Chinese factories. Whats worst is that they allow EMC labs in China to do the certification
and they will say anything for money. The EMC certification process in China is corrupt and non existent in other countries.
The real problems for hams in Western democratic countries is that the authorities wont do anything about prosecuting companies who import products that dont meet EMC standards.
The Chinese and most importers know this and thats why they just keeps on importing the junk.
Plasma TVs get the blame because when they were first introduced, the lower priced ones DID cause massive RFI. Lately, those issues have gone away since the manufacturers are now aware of them.
Hey, I just got a Panasonic 51 inch SmartViera myself, and it's also nearly RFI free when on. When off, no RFI at all.
