I think you're taking offence when you shouldn't be. The eggs point was in response to what kitkat said, that SOGA means all goods must be satisfactory for 6 years. That's a misunderstanding of SOGA, one that is easily demonstrated by the example of eggs, which I'm sure no-one will suggest shoud last six years.
TVs will clearly be expected to last longer than eggs. I'd hope like you they'd be expected to last longer than two years. I'd hope a flagship model would be expected to last at least six years. But all of these are uncertainties and open to the fortunes of the retailer disagreeing with you and then a judge disagreeing with you. I don't know why you mention two years, as kitkat said five year guarantees were unnecessary because of SOGA. I disagree, they give a much more certain level of protection. Even then, as many have encountered with panasonic, they do not necessarily provide complete and straightforward protection.
