Panasonic TX28PS12 (Euro 9L)

[Turnip]

Hi Folks,

Have one of these that cuts to S/by after about 5 seconds. Picture geometry seems OK and aspect variations seem to work (sound too is OK 'till cut)

Only note found was D558 S/C and R578 O/C (Pin 2 LOPT) but these are fine. HT is around 140v until it cuts, and nothing seems to be burning.

Any thoughts  ?  - Chris.
