Why I ask is that in the USA, most of the time you can get a 3 month extension by registering your set. Many miss that freebie and end up where you are.
You made a good point here about keeping stuff under warranty until you can accept out of warranty repair bills. Car makers do this all the time among others.
That is, changing makes won't change the problem.
I have a samsung model # UN55C7000WF when I originally bought it the HDMI ports worked. Then right after my warranty they stopped working. Samsung did nothing to help resolve this instead they told me there was nothing that they could do and that my motherboard was bad. Afterwards the told me they could send me to a service representative and that it would cost over $400 (180 for the part and over 200 for labor). So I have the technician order the part and when they finally get it in they come over to my house and put in the new motherboard. Well the motherboard they brought was defective. So he put in my old motherboard and then I did a system update and my hdmi ports worked. The technician charged me $85 and then left. Now a week after I did the update my HDMI ports no longer work again. With the way this is going I will no longer buy anything samsung and will let my family, friends, and coworkers know not to get anything from Samsung.
