VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

Update on this. I have gotten a new power supply as mentioned earlier and I just received my new main board it was a used model from ebay. I am getting voltages on the power supply and at the main board with the new one plugged in now but this replacement has no ready light no optical light and does nothing. How do I rule out anything else before I contact the seller and tell them I believe I have a dead board?

Did you check shopjimmy, depending on the serial number they might have the set of 3 boards.

SJ out of stock for every board for this model.

So yo are not getting PS-ON when all the boards are connected, correct?
and since you do not get any LED indicator on the front panel of the TV either so there is something going on with the main board. Do you see any red light on the Optical port of the main board?

Correct I get no voltage on any of the pins with the main board connected. I see no red light on the optical port I turned off the room lights and put power to the TV and I cant see any light. Here is a pic of the board.

Picked up a Power Board for this set. Got it all plugged up and it is still dead/no ready light wont turn on etc. However I DO have voltage at the board if I unplug the main board from the power supply. Here is what I get.
Pins:
Pin 1 - Pin 10 show 0v.
Pin 11 - 16.25v
Pin 12 - 4.3v
Pin 13- 0v PS-ON
Pin 14 - 16v
Pin 15 - 16v

At 20-30 bucks on ebay, certainly worth a shot, for a 60 inch tv.

Final bump on this before I order a PS.

Just getting back to looking at this one today. Does the presence of voltage at HV pin help in any way here?

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

That is strange that you do have more than enough VCC (14V, per spec sheet the Vstart is between 13.4 ~ 16.4V) for the IC to run, and once it is running the Vcc is supplied by the Aux winding of the transformer to keep it running.

But I also do not expect HV pin to be 0V since it is fed through resistor network so it should have Voltage at that pin.
Right now the IC is dead bu that VCC of 14V is coming from some where.
Normally at startup the HV provide the Vcc to startup the IC and once it is running the Vcc is provided by the Aux winding. Something is not making sense right now.
I would check the resistors connected to HV pin 1 to see if they are OK or not, also check the resistance between hot side circuit ground and IC pins.

Ok you were correct, it didnt make sense. I put the IC back under a microscope and scraped a bunch of that coating off that was originally on the top of the IC and it was on all the pins too so it was insulating the HV pin from reading. It was like liquid resin or hot glue. At any rate I am reading 103V at HV now that it reads.

Tested a few times here is what I got.

Have you checked the components in the red box

pretty sure I checked that schottky diode and have checked the resistors but I will check again. I am not sure how to test those tiny capacitors?

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

TEA18363 spec.
Use negative leg of the main filter cap (450450VDC rated cap) as the ground ref. for the Hot side circuit, then report the VDC reading of each pin of the IC.
Be real careful since you are working in the hot deadly side of the circuit so do not touch anything with your body or your hands, at least plug this power supply board by itself into the GFCI outlet, no need to have any other boards connected to this power supply board, also do not let the meter probe slip on you.

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

D201 still tested OK?
BTW, still no luck trying to read the P/N of the SMPS IC?

D201 is good I believe. D and S pins read 0.259 . D and G pins read the same.

I was finally able to melt the glue or resin or whatever off the U1 IC. Here is a pic of the number and I will post a datasheet that I think belongs to it.

Re: VIZIO D60-F3 Wont Power ON, No Standby, No Picture, No Sound

I am curious, what DCV do you get on c205 if you measure the Voltage right between the two legs of the cap?

I am not getting any voltage between those legs. Little jumpiness in the MV range but never gets to 1volt.
