Hi Guys,
I've taken the back off and checked some of the voltages, they all seem to show the correct voltage initially however they all quickly drop after the splash screen.
Standby - 3.3v
AU12v - 12v on start
TCON-On - 3.3v on start
TCON VCC 12v - 12v on start
BL-ON - 13v on start
BL-ERR - 0.382v
From the power board to inverter I have the following.
BL-ON - 3.2v on start
BL-ERR - 2.9v on start
UNREG24v pins 1-5 - 25v on start
I've also checked and confirmed there is 12v coming into the T-CON board on start.
Any advice as to what needs replacing at all?
