Question about Televison & Video
The screen control circuit board in your tv is failing. Some of the boards are quite reasonable price wise and if you aren't afraid to open the back of your tv , it is an easy job to replace it . The board you're looking for is the one that has one or two wide flat ribbon cables coming out of the bottom of the screen.

This is a fault developing within the screen, the only remedy is to have the screen replaced, there is no exact answer to why this has happened, it is just the nature of a plasma screens make-up that sometimes a fault can develop like this within the characteristics the display

Testimonial: "Thanks. Might have to live with it as it sounds expensive to replace!"
Either the buffer board is bad or the plasma panel,sometimes it coult be bad connections on the interconnect ribbon cables from the plasma panel to the buffer boards.

hi all .ive had the same problem,a thick black line down screen.sometimes it flickers from top to bottom and other permantly in view.but i have solved it.forget your ic boards and taking apart tv.have you got either a ps3 or wii connected to tv.if so unplug power lead from socket and relocate in seperate socket.make sure the lead is completely free of any other leads and you might just find this works.i think the power lead creates some sort of frequency that the tv picks up .good luck hope it works

Try the following troubleshooting steps.Check power cord and power outlet, possible light switch problem.
Check if you TV savy check the P board if the P board is not good check the fuses on the P board.
If the P board is OK check the A board.
To check these Unplug the TV , Disconect A5 A6 and A7 on the A board and plug the TV in and see if you get a white screen if this is the case your P board should be OK.
