After many weeks of complaining to the retailer (who repeatedly told me it was nothing to do with them and they weren't going to help), I contacted the Finnish Competition and Consumer Authority (KKV in Finland), and they stated that (at least here) the Consumer Disputes Board has previously ruled that a TV should last up to 4 years. As I had noticed the issues with mine just before that, the retailer was obligated to assist - the only downside was that at this point in time, legally the retailer only had to assist with repairs and cover 2% of the repair cost - so kinda pointless.
The retailer continued to refuse to help at all when I contacted them with the information that they should be assisting me in some way. I then sent an email, quoted some of the text from KKV, stated that my next steps would be to file another complaint and take them to court .... and all of a sudden I get an offer of a 20% refund. It's not a new tv, or a substantial refund, but after 4 years, it's better than nothing!
