Top 20 Panasonic Viera TH-42PZ80U Plasma TV Questions & Answers

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.

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

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

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.

Did you accidentally change color settings? Or maybe viewing aspects?

From a quick look at the tv spec it would seem to cope with most inputs so I wonder if it may be due to input type selection. Mine on some inputs have sub options on its inputs which would be in the screen menu (mine has rca sockets and can become component or normal video input). You say you can hear sound but no picture which sugests there is a signal of some sort (tv's and video's inputs become live when a video signal is present but if its poor in some way will not show) but allow sound through. If the game is old then it may not conform to modern standards so present a blank screen. its hard to say what may be the problem but I think input selection or an incompatible signal looks to be a possible answer (if you have your plug ins correct) Hope this helps.....

well snow pix is telling you that all your video ckts are good , and if you get snowy sound then your sound ckts are good , now you need to look at your tuner ckts , but first ck your cables and connections , substituting with a known good cable is the best way of testing it
