What causes the TV to go on and off when first turned on, until it warms up for 5 to 10 minutes

Try turning the volume all the way down then power the TV an see how
long it takes to bring a screen up if you still hear a popping sound then you have a bad part with a bad connection most likey a lamp and wiring.
Call to have it serviced a must if so.

M602 Speaker Problem,.. Popping Sound

This worked for me on my M604: Try inserting/removing a headphone plug into the jack several times to see if that clears the problem.

The "popping" sound is very similar to the sound that the unit makes when inserting headphones into the 'headphone' jack on the back of the unit.

The jack has a contact switch that triggers a relay inside the unit. If that contact switch is 'on the verge' of making contact, slight temperature changes may cause deform closer to it's contact target. The subsequent capacitance build-up and discharge across the gap could explain the cycle of popping noises after the unit warms up.

Popping (electric) sound from back. Caused breaker to pop. Opened unit to get a better look, nothing broken or blackened. Reset breaker. and turned machine "on". No more popping sound. Washer only fills...

Have a look at the capacitor, this is part of the starting circuit for the electric motor.

It is a cylindrical shape and usually splits or bulges.

Post again if you need further assistance.

Tv popping sound when turned on

It sounds like you are hearing arcing from the FBT. The FBT should be replaced before it causes something else to fail.
