Panasonic VIERA - Popular Questions, Answers, Tips & Manuals

Question edited for clarity, full 'make model (what it is). Question moved to Panasonic model category. It is a good set, get it fixed professionally. This is generally the outcome for self repair. https://www.fixya.com/support/r29790007-repairing_own_television ..

It is 13 years after the end of production. We didn't have routers then! There is no wifi convertor in your old Panasonic TV. It won't work without a computer interface between the two.

Three blinks of the power LED indicates an over-current or over-voltage condition in one of the DC supplies of the AP board. The AP board is repairable. Therefore the use of an ohmmeter and peak-hold-voltmeter is required to determine the cause of the shutdown. An over-voltage condition is definitely a defect of the AP board. An over-current condition may be due to a short circuit located in the AP board, A board, or the LCD panel.

Could be a bad remote, that button isn't responding

Good make and it is an HD model with good reviews. It is about 10 years old. It really depends of if fancy a new one or not. I don't advise against home television repair. We see about 10 questions a day here of people who replace boards and still have a non working television. You need the experience and the test equipment.https://www.fixya.com/support/r29790007-repairing_own_televisionhttps://www.google.com/search?safe=off&rlz=1C1QJDB_enCA643CA644&sxsrf=ALeKk00wu8OXxqxE3KlHGB8dHyRz5U2nAQ%3A1609953102652&ei=Tu_1X9uWJ4-ytQWRk6-ACA&q=Panasonic+TC-P50S2+Viera+Plasma+review&..

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

Those 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. http://homenol.blogspot.com/ http://electronicshelponline.blogspot.com/ If blinks continue without any pause, the main board is faulty. Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

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

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

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.

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

If you wish to get some details; visit the site linked here. Pull up older posts. https://electronicshelponline.blogspot.com/

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.

Check the left connector from the Tcon to the panel, if its ok replace the board

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.

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

Unplug it, wait a minute and replug it. Also check the settings and see if it changed.
