I have TV Panasonic TX-P42V20
2/12 suddenly it developed a horizontal ribbon/band 5-6 cm tall across the screen just below middle imaginary horizontal line. It flashes and consists from blocks of approximately 14-16 red tiny vertical columns following 14-16 blue columns, it flashes, sometimes disappears for a minute and remains with any source of signal. TV is less than 2/12 old no warranty .What would you recommend? Tv is still functioning despite the annoying colored ribbon across the screen.Had anybody had similar experiences and how you managed with it?
Thanks for your advice in advance
