Panasonic th-50pz70b bottom screen fault

[netdent]

Hi guys looking for some advice this huge plasma has a problem on the bottom half of the screen skin tones are most noticeable as having a blue negative look to them? hard to describe but as it's on 50% of the screen horizontal bottom I was thinking sustain board? would that make sense, I think the TV is probably too old to throw too much money at but would like to see what the experts on here thought? thanks for any help

Could you perhaps show us a picture of this fault?

Hi Tom, the TV is at my daughters and I doubt it would show in a picture as the clarity is good it just has this blue hue on skin tones!

Thanks for the reply

First guess would be checking LVDS cable, it's an issue that does affect the PZ80s so maybe also PZ70. I would be surprised if it is a sustain (SC) or scan (SD) fault.

Thanks again Tom, yes it's strange as the picture is great and sometimes you struggle to see the problem, most noticeable when faces are up close and take up the whole screen. would it mean changing the cable are clean and re seat?

Just remove, clean and reseat. Usually poking the cable with an insulated screwdriver will make the issue come and go.
These panels do have great picture quality so are well worth saving... the black level might not be great but the overall PQ is excellent.
