The fact that the picture is coming back to normal and then going back to the black and white mode, suggests that it is a capacitor problem. I suspect the location of the capacitors to be the main board, tuner board or the sustain boards. A problem of this extent means that you can identify them visually(cracked, bulged tops, or tiny holes at the top near the X cut). Replacing it depends on your prior experience in repairing electronics. High voltage electronics are not be messed with. The several thousand volts of resident electronic charge can cause permanent disability/death if not handled carefully.

A black vertical bar appears on my tv screen when I turn it on?


Hey!
With Plasma screens and just screens in general, that tends to be a big problem. Here is a link that kinda goes over the problem. http://adf.ly/1fNBRK . You most likely just have dead pixels which could either be a easy solder job or requirement to replace the screen. If you go with the latter, you might just want to buy another TV screen. http://adf.ly/1fNBRK

Dvd player connected to panasonic viera. picture has blue skin tones and picture isn't centered


I always try the simple things first. check the connection. if hdmi .. then try a differnt cable.
It almost sounds as if one of your connections is plugged in the wrong place.

On component.. red to red, green to green and blue to blue .. then the extra red and white go to the video part .. also may want to check the tv manual - sometimes they share those connections with regular rca connection and easy to plug in wrong place.

Rca connetions - Yellow is video - red and white audio.

S video - one big plug and then red and white audio - make sure the big plug is fully in on both devices - I've seen similar things with s-video plug not fully connected on one end or the other.

Good Luck,
Bill.

Panasonic TC-P42U1 plasma. Lost it's vivid colors basic color is black and white and green and blue if tint color tone etc. Is turned up. However a blue ray video plays with full color. Could it be a lose...


I have an old Toshiba TV and was going to replace it with a new plasma because it has suddenly (the week of July 19, 2010) lost color. It has only green and blue tint. Changing the "tint" on the menu didn't help. The color comes and goes relative to nothing that I can measure, such as how long it is turned on, etc. Reading other complaints from owners of Plasmas, I am thinking it is cable related. I have Charter Cable. Playing a DVD, I have to readjust the tint back to normal. Hope this info gives clues.

If it's just one video plug, then perhaps you have to set av5 as being in colour somwhere in the menus.  If you require three wires for the pictures, as blue, green, and red, then make sure they aren't in the wrong ports.
Good luck.
