Recently my VT65 has started exhibiting sparking/misfiring pixels, it manifests as sparkling white pixels in the black area if there's brighter pixels in the same horizontal area (e.g. the smart viera boot screen, white credits on a black background).
On inspecting the screen closley you can see pixels misfiring in the upper area of the screen at all time, it just gets lost in normal content.
I've tried (without success) replacing the P/SS/SC board (refurbished boards) and re-calibrating the VSUS (including setting it to HIGH) but none has made a difference.
The panel has about 18k hours on it so ideally I'd like to fix it. The generic recommendation for this seems to be increase the VSUS but it's already set to HIGH and at 218V (The max according to the service manual) so I don't want to push it much further.
Any input on this would be most appreciated.
