Hi Everyone,
I'm new here so sorry if I ask obvious or already answered questions.
I have the above plasma TV since mid 2012 and its worked fine up until today.
I'm getting what looks like vertical blue banding intermittently (only about 10% of the time, but I'm afraid of it getting more frequent), at other times I'm getting purple/blue areas and sometimes slight horizontal ghosting/dragging when I use the menus. I downloaded the service manual, I checked the Va and Vs voltages, they were very slightly high, so I reduced them, no change.
While I had the tv open, I cleaned out alot of dust, while aware of static electricity dangers.
One thing I thought was interesting was that I can make the fault temporarily go away or manifest itself by changing the screen brightness and it seem to either start or go away when the scene I'm watching changes as if certain screen images cause the problem, like the tv cant handle them..
From the manual, the problem kinda looks like scan type mal-discharge which would indicate the y-sus board and/or the t-com board,
The tv firmware is 3.13.33.
I guess what I'm asking is that could this be a cable/connector fault or is this possibly the start of the end of the panel itself ?
I can source both the y-sus and t-com boards on ebay.
any help and suggestions would be very appreciated,
Dave
