My Panasonic viera flat screen is blinking 4 times and pausing...what does this mean?

These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

God bless you

I had the same problem with my Viera. if you disconnect the power and ribbon cable from the YSUS board (check youtube for how), the light led will blink 6 times, indicating the YSUS is bad. Check ebay for TNPA5175 board (about $115-160). The "pop" is one of the DG402RP chips burnout. These are about $4, but only available from China. If you can wait a month for delivery, you can solder the new one to replace the bad one. You may want to purchase several in case more are bad or it happens again.

power supply faulty indication

When the SUB5V or MAIN9V/SUB9V, short or over-voltage 15V short condition occurs, the TV shuts down and the power LED blinks 10 times.

Loss of power from power supply. Usually bad power supply.

A red light blinking 10 times means that a video board has gone bad. Contact Panasonic to see if they will help you out.
