Vizio Sound Bar No Power Pls help

Re: Vizio Sound Bar No Power Pls help

Hi and thank you for replying any help to get thru this would help ok so my knowledge with electricity is beetween the middle of beginner knows a lil more then average Joe so take make it easier I don't understand wht u mean by WVDC ratings of those caps are u saying to check each cap individually? to see wht power they should be getting on cold side those caps I'm getting 24v on the hot side the big cap is 15v I can't tell it jumps like fluxiates also should I check the other big board on the right side but since it don't power on I'm assuming it has to do with the power board

Re: Vizio Sound Bar No Power Pls help

Hi posted some better pictures could it be my power switch is broken since I'm receiving voltage on the power board also how many volts should I be getting on the other board? not the power board

If you know which conductors bring power TO the board, look at the voltage rating of the caps that it encounters, there. The supplied voltage will not exceed the WVDC ratings of those caps (and will typically be at least ~40% less).

Re: Vizio Sound Bar No Power Pls help

Better pics of my power board cause I still believe the Issue of not powering on is on tht board

Re: Vizio Sound Bar No Power Pls help

Cannot help with very poor quality pictures. I cannot read anything on the main board except the P/N of the board..

Ok I opend the whole thing to take better pics

Re: Vizio Sound Bar No Power Pls help

Well, you have that ONE connector(the pins are labeled with +24/+24/+24/GND/GND/GND) on the cold side that provides 24VDC to run other boards when all the connectors are back in place, so it should have the 24V right at the connector.

Post #9: I ask you to check the Voltage between the two legs of the main filter cap but your picture on show the Red probe on one leg, so where is the black probe that is supposed to be on another leg? But that is not important any more because you are getting the 24Vdc on the cold side without other boards connected to the power supply board, you need to have all the boards back in place and verify that the 24VDc is still present.

Ok tried on this pins tht are labeled and I do have a 24v on each point here are pictures of other board let me know if I need to open it better to get better pictures tht is the only board I have removed and placed back the power board

Re: Vizio Sound Bar No Power Pls help

Nope. That's 120VAC connector in hot side.
Man! I hope you DO NOT get electrocuted.

Lol live and learn right I have some technical experience to make this far �� either way I appreciate ur help as well other others by the way I did zap my self Abit on speaker part small shock

Re: Vizio Sound Bar No Power Pls help

Sry yes it's very difficult to take picture one hand and the other to point to the prongs ok so I bassicly tested out by putting the black prong on negative and the red prong proon positive to get the 24+ I will try the other connections u mention to see wht I get

Re: Vizio Sound Bar No Power Pls help

This prongs correct to the right

Re: Vizio Sound Bar No Power Pls help

We will need the pictures of other boards to see how they are all connected together.
Do you have tools to do SMD repair?

Re: Vizio Sound Bar No Power Pls help

Hi what do u mean by right on the connector pins the one with two prongs sticking out wht do u think can be the problem no power on Vizio letters light up

[budm]

Re: Vizio Sound Bar No Power Pls help

Well, the power supply is working otherwise you will not have the 24VDC, so you should also see the 24V right at the connector pins.

Re: Vizio Sound Bar No Power Pls help

Pictures of the 2 caps on cold side both of the getting 24.02v
And the big one by self on hotside thts cap ur talking about right? on hot side15.24v to 15.25v

Update: if I put the multimer prongs to test leg a lil bit higher I'm getting 156.7dc to 157.8dc on the hot side on the big brown cap so I'm assuming no I'm not getting 160v if thts correct cap ure pointing to on hot side

Re: Vizio Sound Bar No Power Pls help

Nothing to do with component tester. I am asking you to test the DC Voltage between the two legs of the main filter cap on the hot while it has AC from the outlet feeding it, you better be real careful while performing this test with live power. We need to find out if you even have 160VDC on the main filter cap or not.
"with the power board disconnected and no power to it and there's no continuaty on both medium caps on the cold side 24.02V and on the hot sidebon the big cap beetween 15.24-15.25v "
What do you mean 24.02VDC and 15.24 -15.25v If have no power to the power to the board? Very confusing. Are you saying you are getting 24.02VDC on the cold side?

Sry for confusion ok so with everything connected DC power and my multimeter to test the legs beetween each leg on cold side both caps are 24.02v

And on the hot side the big brown cap when I test the legs beetween it goes 15.24v to 15.25v as I go lower to the legs and Board to test it fluxiates like bounces around on the hot side with power coming from wall as DC

Re: Vizio Sound Bar No Power Pls help

Hi I don't have a component tester Wich is good one to buy tht recommend I see alot of them from china only multimeter I'll have to get one later this week I checked for continuaty with the power board disconnected and no power to it and there's no continuaty on both medium caps on the cold side 24.02V and on the hot sidebon the big cap beetween 15.24-15.25v it just going back forward some times lower

Re: Vizio Sound Bar No Power Pls help

So you are not getting ANY Voltage at all on the cold side?
What DC V do you get when measure right between the two legs of the main filter caps in the hot side (be real careful since you will be working in the deadly side of the circuit)?
