Samsung 65" Plasma, failed twice, first time main board, second time power supply board. Luckily I had square trade warranty. It's just over 5 years old now and does work fine and has an amazing picture.
Now for their appliances, have the whole kitchen suite...
Gas range is fine
Dishwasher has been repaired once under warranty (dryer fan LOUD!!!) and when the water brake (strange name for the water inlet canister) failed square trade determined that the dishwasher was unable to be repaired and refunded me the purchase price. Now the price of dishwashers has just about doubled it seemed! Ordered the water brake and fixed the problem (dishwasher would fill, then drain, then refill and work). Then the dishwasher started leaking some out the door bottom. Replaced the fan/evaporater dryer and its working perfectly again.
Refrigerator leaking in crisper tray and ice maker freezing up. Actually repaired the leak with the water drain fix and replaced the icemaker and sealed up the enclosure and its working fine with an occasional ice jam.
Microwave is still working but does get quite loud after 5 minutes or so of use.
The problem is that all appliances seem to be junk these days... no matter what brand, people are always having problems if you look at reviews. Best to buy what you like and get the extended warranty... some places have fairly good prices, square trade was good, but they are more expensive now.
Dread having to buy any appliance... period!
