| Need schematic diagram for 55LE5400 Power supply board. P/N of board I need EAY660908801 model # LGP4247-10 10P. I have already got the service manual but I do not see the schematic for the Power supply board for this TV so I can troubleshoot the unit based on the direction on the service manual. |

|
Recently, I believe my TV stop working. I was watching tv and the screen went black and no sound. One thing I noticed is that the standby light is still on. I can turn the TV on and off with either the remeote or on the TV itself, but no picture. Fuse is intact, the caps look ok at least visually. We had some rain and lightening and I think the power supply must have seen a spike. The TV was connected to a Monster power surge protector and I don't understand why it would have failed. I am looking for any suggestion on what to check for and I am trying to locate a schematic.
The SMPS P/N LG4247-10 10P EAY60908801 Rev.1. Where can i get a schematic and do some troubleshooting. |
