Re: Vizio E60-E3 power supply repair



I apologize for abandoning this thread - life happened, and then continued happening.

I replaced the TEA18363T IC and no change in response so far. I think I had counted my pins wrong because double checking everything, all the voltages across that chip seem within range. In reference to the ground on pin 2 of the chip, I get 14V on VCC (pin 1), 60V on pin 8 (HV), and 0V on pin 5 (VAUX).

As for the transformer, I'm getting ~170V across the primary winding on the hot side, but nothing seems to be working...

Re: Vizio E60-E3 power supply repair



In standalone I don't get any voltages on the connector.

R12 reads 64.5 kohm.

Q1 reads ~0.5V activation in a diode check crossing the HV separation cut on the board. Between pins 1 and 3 on it reads a pretty low resistance (beeps on a continuity check) but there's a couple SMT resistors bridging those so that may be normal behavior.

Both those measurements were in-circuit, I can desolder later tonight when I get home from work if need be. I appear to be the first person working on the board...

Re: Vizio E60-E3 power supply repair



To clarify, I tested all the voltages above with the board standalone. It's definitely something to do with the standby circuit....

Hey all,

I have a Vizio E60-E3 power supply board (1p-1156800-1010) that is non-functioning. According to the last owner, it got damaged by a lightning strike or a power brownout.

I'm pretty new to repairing these sorts of things but I've had some success in the past. This one is throwing me for a huge loop though.

There's no standby voltage on the board at all. Actually, on the connector there's no voltages at all. Diodes seem intact and weren't shorted or blown, MOSFETs seem intact and testing them as diodes looked okay, but I'm not 100% sure if I've been...

Looks like this is the place to be! I got routed here from the registration email but I'm looking forward to interacting with everyone here. I've definitely gotten some great advice just by reading over threads but I have a few questions of my own, so here's to posting!
