Re: Emerson LC39LEM3

In post 1 he doesnt say the red/black to the inverter was not connected ,he just says the cables to the main board were disconnected - did you think otherwise?

Re: Emerson LC39LEM3

OK, I read the post wrong, then yes the PFC may try to kick on or the inverter circuit kicks on and cause the fuse to blow. The MOSFETs for the PFC and for the inverter transformer are connected directly to the mian B+, so some how when the IC being told to drive the Gate, the out put just go HIGH instead of switching ON and OFF at high frequency so it draws lots of current and caused the fuse to blow. We will need all the P/N of the PFC and for the INVERTER drive IC.

Re: Emerson

I'm working on one of these (LC391LEM3) also a power supply issue.
It had a blown fuse I check it over replaced the fuse.
I have 3.3V and 6.8 for the PON 12V
I suspect the PON 12V is an issue.

Suggestions?

Anyone have a print or manual on this?
