T-con 6870C-0267A problem help

[Pragmatiko]

Hi all,
i have that t-con with a problem.
IC TPS65162TI is going to be very hot. I have already replaced it without success.
If i put external 12volt on L1 the absorbment is 450mA and ic go to be hot.
If i remove L2 ic is not more hot. I checked absorbment on L2 circuit and is just 100mA, also i have replaced L2 without success.

Checked some short capacitor but nothing. Can someone help me?

Thank you in advance.

What is the symptom you are getting that lead you to believe the T-CON is not good?

how about checking the load that is connected to the circuit, may be load is drawing too much current.

Hi Budm, which load I need to isolate? I have removed L2 coil and seen that without L3 ic is not more hot. But if I put external voltage on output of L2 there is just 100mA absorbent.
