I have had two televisions just quit working in the last two months. They are older models, but have been working fine. One was a 26" Zenith that is about 10 years old and quit working about 2 months ago, and the other is a 32" RCA about 12 years old that just stopped yesterday. They were working fine, and then when we turned them on one day they just didn't work. It just seems odd to me that they work fine one day, and then the next day they are just dead.
Well unfortunately it comes to us all in the end with old age. It seems to me the two TV's have joined the 'Dropped dead without warning' club. Either get someone in to test for the fault or invest in new TV's.
However if you electric minded then remove the back with set OFF and unplugged and look for the internal fuse near where the power cable comes in check that's ok [both sets] can't say other than that without carrying out a ciruit test.
