Default RCA RNSMU4336

Working on RCA RNSMU4336, SN A1901272410000314, with
screen rendition issues, for any/no input.

Display stretched, gradually moving off-screen towards the left,
eventually (~minutes) displaying black screen (all lamps functioning).
All power circuits functioning, until VDGAWR1 shuts off (black).


Haven't had much luck getting response from regular service
channels in Canada and web search hasn't produced much info.

Any hints?

RL

Since it displays a problem that evolves over minutes, I'd see if it could be detected thermally. When the image is moving left, spray it the main board with freeze spray to see if the cold has any effect.
