Red squiggly lines all over my Panasonic Mutlimedia HDTV
I first had the exact same problem with a green and red "ball" on my t.v about three months after I replaced my bulb. Because I did not re-update my warranty, we have just delt with it. I will now be calling them, However, I now have a new problem. I have pink squiggly lines all over my picture. They look like vaines all over peoples faces and the background. My aunt said she had the same problem and she called Panasonic and hassled them enough to fix the problem for free. Has anyone else had this problem? Any words of advice?

Re: Red squiggly lines all over my Panasonic Mutlimedia...
I've seen this sort of effect on Sony, Hitachi, and Mitsubishi LCD projectors too. Its a defect in the LCD panels. The issue here is heat. The high temperatures around the lamp can go even higher when the ventilation system of the TV has been clogged by dust and other particulate matter, especially cigarette smoke. The lamination of the postage stamp sized LCD panels is damaged resulting in deformities which affect picture quality and uneven color rendition (blotches). Some manufacturers have helped their customers when approached and others have been compelled to because of class action lawsuits brought by angry consumers.

Line, faults & possible causes to LCD screen are given with illustrations. You can get an idea about the fault to an extent.
The 3-blink power light code on this model indicates a fault in the A-board (the one with all the input jacks) on the 3.3v line, according to the service manual for this model. The easy solution would be to replace that entire board (Panasonic part# TXN/A1FFUUS), however its somewhat difficult to find in stock now and when you do, it tends to be expensive. I have the same T.V. with the same problem. Currently, I am trying to isolate the exact board component responsible for the failure, but as of yet no luck on that. If I do find it, I'll post back with more information on what the problem was with mine. Meantime hopefully this at least helps you and others with the same issue to narrow the problem down a bit. :)
The three picture cords (red/blue/green) often are a little larger around than the sound cords (red/white). If they are they same size, they are often grouped separate by picture and sound. Double check to verify if you have the "red" cords correct. Good luck.
There are actually two red leds present on your tv and depending on which one is flashing is going to tell you what to replace. 3X on the Temp led will point to a faulty thermistor and you would want to replace this part. If the 3 red blinks are the lamp light than this is a error on the iris position and you would need to have the optical block replaced.
Are you from US or Canada? I'm Panasonic authorized and allways Pana covered the warranty after 1 month from the expire date. Call Panasonic Viera service and tell them the story. I'm sure you'll get refound.
Anyway, a horizontal line doesn't mean the PDP is defective. It's one scan IC burned on the SU or SD board (depend where the line is). We allways replaced the SC bord each time SU or SD got burned. If after SD and SC replacement it still defective...yes the PDP has one scan line in short.
Call Viera and insist to get warranty. Let me know. Good luck!
I had red and green spots, and I called the service department at the furniture store where we purchased our 42" TV. They said it needed to be updated, and they picked it up, fixed it, and delivered it back to the house for about $25.00. We had a warranty, so it only cost for coming to the house twice... No more spots!
