I am hoping that there is someone out there who can help me out or steer me in the right direction.
About 3 months ago my Panny plasma (bought in 2009) developed a pixel width vertical line just off centre of the screen. The line stayed constantly on for about 3 days and then disappeared after turning on the tv on the 4th day. I knew that problems like this don't just correct themselves so I left it until now.
Since then, it has progressively been getting worst where the line will appear for a good week or so of watching tv and then dissappear for a couple of days and this sequence has repeated itself for about 2 months. The line would not always come back in the exact same spot but it would be vary about 5-7 inches each time. Last week 2 vertical (pixel width lines) now appear just off centre of the screen (about 6 inches from each other) and they have not gone away like the previous line - sorry no pictures available.
I have been reading where other people have had vertical line problems with their Panny's and tried to reseat and clean out where the connectors go into the C2 board. I tried this and carefully pulled out the ribbon on the back of the C2 board where the problem areas are and no luck - still the same 2 lines appear on the screen.
I am ready to pull the trigger and order a new C2 board but I just wanted to see if anyone else had success with a similar problem after replacing this board? The affected area of the display seems to be near the centre of the screen so I assume that I only need to get the C2 board and not the C1 and C3 boards as well but correct me if I am wrong.
Also, I don't know if this makes a difference but my main circuit board was replaced once under warranty about 2 years ago because of power up issues with the tv. All has run well since this fix with the exception of the last 3 months with the line issues.
Your help and suggestions are very much appreciated.
