There are two things that can cause this, a buffer board and the plasma
panel itself, the bad news is that there is no way to determine what one is causing it without putting the buffer board in the set. If the buffer board fixes the problem then case closed, if it does not fix the problem then the plasma panel itself is bad and the tv will be non repairable because the part will cost over $1300! Yes that is not a typo it is really over $1300.
Now if you have a professional install this for you, you can expect a bill of around $300-$400. Now that repairman is taking a risk because there is no way to know if it is going to fix it because the manufacture made no way to troubleshoot it, therefore he might pass the risk off to you and say something like:
If you want the board replaced and it fixes it then it is going to be $300-400 (whatever he charges) BUT if I put the board in there and it does not fix then problem then there will be a $150 fee for trying, this is to cover my time and the expense of sending the part back and the restocking fees I will incur.
