For awhile now, ive been having problems turning on my TV. Sometimes it would take awhile before my picture started. but today it wont start at all! Sometimes when i turn it on there will be sound but no picture and sometimes there will be "clicking" sounds (like 10 clicking sounds for each time i change the channel) but the picture wont start. i called the magnavox customer service tech. and he said it sounds like a power supply problem. Does it sound like a power supply problem? Thanks for the help.
