Im sending you a solution posted earlyer by DOCTOR VIDEO

red verticle lines are most likely a bad tube or convergence problem. You will not be able to fix this your self . I suspect a bad convergence ic cost for parts are around 45.00 servicer charge about 250 to fix. At least know when you call a servicer you will have
a good understanding of problem.good luck.

    Remember that televisions have high voltage circuits, and other circuits that hold voltage even when unpluged. Repair should always be done by a professional. If you do decide to repair it yourself please do with caution.
     

    The convergence circuit is part of the deflection board (D board). You could replace this board to fix your problem if you wish.

    However sometimes replacing the D board is not enough, on some occasions there is a pico fuse or two that will open on the G board and if you replace the D board you will still have the same problem until you change this fuse. You will need to be able to use a multi meter and be able to solder in order to take care of this fuse. 

     

    If you have more questions or need any more information please let me know.

     

    Thank you,

Blank Screen - Panasonic PT-50LC13-K


Hey Ben, The TV is alerting you it is about time to change your light bulb, it will keep on doing this until the light bulb just dies.
Order your Bulb via On Line at any of the places, there are different prices, but average for the authentic one with the chasis included is @ 260.oo and only takes @ 5 days to get delivered. You can save up to 140.oo if you just order the pure light bulb, and go the extra mile changing it, I just explain someone how to about it, only takes you 30 mins. Good look, I hope I get help for my problem too.
