Question about Magnavox 37MF437B37 37 in TV
That is a very common indication of failing filter capacitors in the power supply board. When the capacitors can not hold a charge right they prevent the power board from starting up until they build up a charge. As they get weaker they take longer to get the charge until one day they will not be able to hold any charge. Here is a link to information about what values of capacitors to change to get the board back up and running.
I hope this helps,
