I FAILED TO FIX our 13 year old 42 inch Viela TH-L42E5 (sold in Japan), the image of which moves up and down by about 5mm or so every second or so. [br]
I tried everything in a Youtube video[br]
Remove plug and press power for 30 seconds[br]
Plug into a wall not a multi-socket adapter.[br]
Replace HDMI cable[br]
Push in HDMI cables and socket[br]
Reset settings[br]
Attempted to turn off Ambient Light brightness adjustment (none)[br]
Attempted to change the display mode to sport (none)[br]
Tried different zoom settings (normal, zoom)
None of these worked, so [br]
I removed the screws on the back panel of 4 types, about 30 or 40 screws[br]
-
Removed the rear panel and used a can of compressed air to blow away the dust that had formed on top the central LED driver (?) panel.

Removed the rear panel and used a can of compressed air to blow away the dust, of which there was quite a lot, that had formed on top the central LED driver (?) panel - the brown square in the image below. I also blew on the other panels.

But it still moves up and down every second or so. The frequency of the movement MAY have decreased but I could so more dust to blow away. The flicker is not that bad (yet) so we will take our time about getting a new television. I think that 13 years of service (bought and built in 2012 in Malaysia, now 2025) is okay so we may get another Panasonic.
