Hello,
I have Magnavox 51" TV, model 51MP392H/17. and the IC"S went bad on it but before I found this web site I adjusted the tubes in the back of the set thinking it just needed to be tuned in!
Not such a good Idea , I replaced the ic's and now the set still will not stay on it powers up and 30 sec later it turns off no sound no pic at all , When I was turning the adjuster for the blue tube it over powerd the tv and turned off thats what started it all..
