Power/Inverter Proview PI-XXXXTLTX V-A

[Turnip]

Hi folks,

These Proview panels come one inverter trannie or two (15/19 inch)  My prob is with Hitachi HIT19WDVB with the double trannie where after changing all suspect or pregnant caps, inverter goes off after half an hour - sound continuing.

Anyone solved one without a hammer  ?  - Chris.
