Keep in mind RMA / Warranty policies differ from country to country. There is no standard practice. As HenryNettles said, it also varies according to the very person you are talking to. That is why it is often important to record the name of the service person you talked to and exactly what job title that person had at the time of conversation. In South Korea, services are exceptionally good and easy but South Korean consumers pay 2 times the export price. Whether you want to pay double to have a little better services is often at issue. Personally, I'd rather have a DVD writer or a HDTV at 1/3 or 2/3 prices from the regular ones without any kind of warranty. Failure rate is usually close to zero and by the time an electronics hardware wears out, I'll have far more updated replacements.
BTW, after my daughter did something, my PCH-S2300 camera phone and Gen Networks DivX player can't be played on TV. I don't know whether the cables have gone wrong or whether some boards failed. What I do know is they both went out of order right after she did something to them. I can either send the phone to Samsung service center or visit one myself. I can also send the DivX player to Gen Networks HQ in Seoul, or send it by mail service or anything else. Either way, it doesn't take more than a few days to get replacements or make them fixed and have them back. But if it's just the cables, it's easier and faster to order new cables from Samsung and Gen Networks.
