I have a Sanyo DP32746 with the date Nov 2006. I'm getting no display on the screen and the power failure circuit keeps tripping. Pin 32 and 36 of the CPU are feed back pins for fault condition. I'm not getting 5 volts on the 36 pin which indicates the issue is with the LVDS. I checked the voltage going to the LVDS and its not there. The supply for the LVDS is IC1621 which is a LA5774. I'm getting 24V into the LA5774 but nothing out. I need some help figuring out if its the IC1621 or something thats controlling it. Any help would be appreciated. -

Re: How do I fixed a shorted MOSFET?
The 4 pin power supply connector is used to provide +12 VDC to the processor voltage regulator. Posibly you may have a bad or shorted cap around the mosfet. Mosfets often most likely burn open after shorting. A bad cap not always is puffy or leaking, I have replaced hundreds of good looking caps. I use a MUL3333 cap tester.Leave a comment:

Re: Vizio m550nv
I had this exact problem on my Vizio 47" HDTV.
I removed the speakers and all the screws on the back cover.
Took the cover off and located the fuses on the largest circuit board.
The are in the upper right hand corner of the board. There are 3 of
them in a row labeled LF 1.5,
LF 3.0 and LF 3.0. The are white in color with copper ends.
I took a volt meter and measured continuity across all fuses individually
and found the LF 1.5 to be blown. The guy at the electronics store sold me a barrel
1.5A fuse and...Leave a comment:

Well to whom may still interested to fix this issue.
NO PICTURE HAS SOUND
CLEAN THE 3 RECTANGULAR COPPER CORNERS OF THE INVERTER.
