Tv Tech does not do warranty work, nor do we accept credit and debit cards, doing so would require us to raise prices to cover the additional cost of doing business. We can not give an estimate without looking at the set to determine the exact cause of failure, anybody that gives you an estimate on the phone is just throwing a number out there to lure you in. We did not try to be rude to this lady, just responded to her questions but she did not want to hear the answers. When you have a warranty problem you must call a warranty servicer. I apologize for your bad experience Judi, but we were not rude, just honest.
