TV Technician: Anthony_Infotech, Technician replied 7 months ago

Couple of things here it could be a failed buffer board or a problem with the main-board OR it could be lead issues, what we would do is re-seat all the ribbon leads connecting all the boards together in the set, then decide (if that did not work) if a board is bad, checks with a volt-ohm meter is needed too here

TV Technician: Anthony_Infotech, Technician replied 7 months ago

These issues are not easy with plasma its a case of closing everything down as the cause,issue could also be the plasma panel itself

Customer reply replied 7 months ago
do you want me to switch off the telly<
TV Technician: Anthony_Infotech, Technician replied 7 months ago

If you have experience with test meters and are able to follow instruction it may lead to replacing a board or two ,so you do need to also understand the age of the set and costs for boards here which could run over $150

No I dont want you to do that I am explaining the issue you have

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 7 months ago

I am not sure if injecting $150 into a plasma set of this age is a good idea?

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 7 months ago

And that is if you do the work yourself and are able to gamble its not the panel itself which is not replaceable

Ask Your Own TV Question
TV Technician: Anthony_Infotech, Technician replied 7 months ago

Customer reply replied 7 months ago
