SONY KDL26L5000 repair

[budm]

Got this one in today, when you first plug the power cord into the outlet, you hear the relay clicks on but then clicks off.
Check 3.3VSTBY, it only shows about 0.25VDC. Removed the cable to the main board, power backup and then 3.3VDC is OK using dummy load.
Check the resistance 3.3VSTBY pin and Ground on the main board and it shows 3 Ohms. Start disconnecting the connectors attached to the main board, when the connector to the IR receiver/LED indicator board the 3 Ohms reading goes > 500 Ohms resistance.
Remove the IR board and inspect the MLCC and find that the C9101 10uF 16V MLCC shows 3 Ohms, so I replace it with lytics cap instead sine I have lots of room to install regular lytics cap.
TV now turns on and works just fine.

Way to easy to find. You hardly did any work.

I think he made it "look" easy. The well experienced often do.

I was not going to bother with it first because it is only 26" and the 3.3VSTBY goes to so many places, if the unplugging the connectors did not cause the 3 Ohms to go away I would not have try to fix the main board.

But you fix it so there is one less TV in the landfill. Good for you.
