The X-Sustain board has the fault I presume. Just visit this site, named 'Electro-help'. This type of fault, and its repair proceedings are detailed there with illustrations. Check this link and select the site. Pull up older posts there. Sometimes, ads attached with each posts there might give you details of the components availability too.

There is a vertical black bar along the left side of my TV. It started as a thin yellow/white bar and has grown to be about 2 or 3 inches wide, blocking that portion of the screen.


The LCD wafer has gone bad, and more lines will begin to appear over time. It can be replaced but the cost may be comparable to replacing the entire television.

65" Panasonic has 4" vertical black bar!!


By your detailed description, it sounds that there should be a loose connection with the 'COF'; connected to the screen. All of these COFs, can be located at the bottom side of the screen [looking from back]; in a horizontal row. If you wish to get more details to this fault, check the site kinked here. It has screen-shots of defective plasma TV screen, and possible faults.
I should appreciate you for this detailed description, that a few users will provide.

Panasonic TC-P42S2 .. Transparent 2 inch wide vertical discoloration on panasonic 42 inch plasma, very left of the screen.


Fixed mine, myself! Black 3 inch vertical band (stripe) appeared after a cros country move on our PC-T50G10. Occasionally we would see white band with multicolored pixel width stripes. Took the risk of taking off the back to see if I could see anything. Found places on sides and bottoms where plastic like 2" flat cables could be seen. Guesstimated where the band was and found that I could flip down a black cover on one end of the cable. Tried to pull it, gently. Mistake. Realized it wouldn't one out like computer hard drive cables, so I took out the screws holding the plate on the other end (it's only an inch long). That allowed me remove the cable. Took it out, cleared away dust, put t back and closed the black over. It worked! Put the screws back in, back on and... we are happy (although I do have four extra screws!). Just be gentle.

A black line running verticall down the middle of


There is no invertor board on a plasma tv. The fault is the X address buffer board. This is located on the bottom of the screen and runs horizontally the whole width of the screen. If you remove the heatsink plate that covers the x address boards and you need to look at the screen ribbon at the same position as where the bar is (in the middle).Vary gently lift the Xbuffer ribbon lock and gently take out the ribbon.Clean the contacts very carefully with a fibre pen or an electrical cleaning fluid.Insert ribbon back and heatsink and check.Here is a picture of the board and ribbon

a 1 inch bar is associates with 1 ribbon fault. So if the bar was 3 inches in from the left of the screen, the faulty ribbon will be 3 inches in from the right working from behind the TV. If cleaning dont cure the fault, then the Buffer IC will be blown and order a new centre buffer board (you can buy off Ebay)
