Question about Panasonic Televison & Video

3 year old Panasonic VIERA TC-P54VT25 screen has a series of horizontal red dots from left edge to middle of screen in lower half of screen. Visible when the picture is dark. Not so visible when the

The red dots look like a horizontal line of dashes. The red dots are viewable in all the different inputs -- DVD, cable, game input, etc. Are the plasma cells wearing out? The TV is over 3 years old and I'm not sure if the warranty covers this. Thanks.

SOURCE: plasma TV with vertical lines

Help! My Plasma by Magnavox is putting black verticle lines on the right side of the screen - comes and goes - and I replaced the entire Direct TV-HD unit - wires, everything - and had TV company repair - and it still came back. The TV repair refuses to take TV back because it does not show up when they come. Although I videotaped it and showed them which has the date and time - they still refused to take it - and tried to get me to sign a paper saying it was working while they were there - which of course I refused to sign - so they left and nastily said they will not be back-find someone else. I still have the lines - and do not know what to do! Can anyone help?

SOURCE: Samsung HPR4252 with red horizontal lines accross the screen

I just had my HP-R4252 repaired on 12.05.09 with a similar problem. The picture is covered in horizonal, broken lines and the color is predominately red. They lines are grouped together in large bands across the screen.

The tech replaced the Y-Buffer boards (Up) and (Low) in about 20 minutes.

SOURCE: HDMI inputs are not working

As crcelect suggests you can run the TV on RCA. You should also be able to use coax directly from your cable box. If you don't have cable you can use an rf converter to connect coax.
I have exactly the same problem with my Panasonic TH-42PX75U. I've been told that I may need to run a setup on my cable box to fix the problem. If I find a solution I'll provide details in a future post.

Iwas watching my panasonic plasma and the screen went green.


One of the "Y" buffer boards have failed. The buffer boards are located on the left side of the set looking from the back. There are two of them. One for the upper half of the screen, one for the lower. Disconnect and replace the one that had the blank portion of the screen.
