That probably won't work. You'll have that problem until you get a new TV.

Most likely is the power board,so I hope you got a good one! The next would be a short on the SC board. The main digital board could be defective in mis diagnostic. Disconnect the SC board and see if the blink code changes. if it changes,the main board is good. If you have a good power board,I vote for a short on the SC board to be checked

Your Tcon board is failing

If you are using a direct Cat5/6 cable connection between the unit and the modem, you should not have to enter any codes as this is a direct communication from one device to the other. If you were using Wi-Fi Wireless, ye; then you need codes to authenticate the connection.

It sound like you are using a component video connection to the TV, which is of variable specification. Try a different type of video feed from your Comcast box

No this TV does not process video files from USB. To improve sound quality reset the sound settings to midrange on all settings. Too much bass causes the sound to be muddy, especially on vocals

This fault is most likely caused by the plasma panel itself, which would be prohibitively to replace. I suggest contacting Panasonic service and tell them about your problem. I have known Panasonic to be very good in the past, often still helping out even when the item is out of warranty.

I would say that's pretty much had it ,if there's smoke coming from the back something has burnt out I would take it to a TV specialist to see if it can be repaired Nick

Check the part number with the board

Use the tv setup menus. Menu->Audio Adjust->Stereo/SAP/Mono and turn off the SAP (Secondary Audio Program.)

I will be the barer of bad news. your Panel is failing. Plasma TVs are only made to last 5-7 years. 10-12 is more realistic from what I have seen. The TH46pz85u is a great model of TV but when that starts happening it means the panel is beginning to fail. Replacing the panel is cost prohibitive and they don't even make them anymore. You will be wise to spend your money on a new TV. newer TV's are much more power efficient as well. your 46" TV draws a lot of electricity. Your TV draws almost 650Watts of power. A comparably sized TV today(55" or larger) Draws around 200 watts. Significantly less.
