Panasonic TX-42PV71F Video nok, Audio ok

[Timo_AUR]

Hi,

the Plasma TV from Panasonic (12 years old) shows the following error pattern:

Input over HDMI 1 or 2 => same error pattern
Audio signal ist ok
No Video visible (the plasma screen is dark grey)

All Elkos have no visible damage

The error appears after 5 minutes.
A cold spray treatment brought no change.

Best regards

Hi,

The Plasma TV is working again.

Solution:
DG PCB TNPA4226 Connector DG5 was oxidized.

After cleaning, the picture is back.
