Panasonic Viera TH-50PZ85U makes buzzing noise on 4th day of use

I would first check any of your inputs (i.e. cable, satellite, DVD player, ect...). If you hear this buzzing sound regardless of what input you are using, then it has to be the TV. If it's the TV causing it, audio is produced on the main board or A board named by Panasonic. It is the board that has the A/V inputs on it (cable, HDMI, component). This model has 2 different main boards it could use either TNPH0721ACS or TNPH0721ATS. As a TV repair technician, I often use Tri-State Module and would recommend them for parts. If you don't know which board you need, their customer service is helpful. I hope that helps.

Here you go this usermanual from panasonic should have all the info you need.

I've found many tv stands on that site

Contact the authorized dealer for Panasonic at your town.

My ex-husband threw away the pedestal stand for the Polaroid Polaroid FXM-3211C TV DVD Combo which I now have. I need a pedestal stand....do you know where I can find one?

Can you tell me how many blinks is it?

Most common thing to happen is a capacitor went bad on one of the circuit boards making the loud POP sound. Odds are it's on the Power Supply Board if the TV isn't showing power at all. The picture below what a bad capacitor looks like.



They range from different sizes and color. Swollen, deformed, and raised top is the thing to look for.



Solder in a new capacitor on the board or replace the whole circuit board.

Unplug TV, unplug HDMI cable, plug in tv, turn on, plug in HDMI

Found the screen had a small crack and was shorting the video circuit.
