Vizio D55un-E1 burnt ceramic capacitor identification

[ITF]

Hey, I'm extremely new to TV repair. Long story short, TV popped when I turned it on, opened it up, located the burnt ceramic capacitor, but the label with the info on it was burnt out. I don't know much about this stuff, so I was wondering if anyone could give me some info on the capacitor I would need so I could solder in the new one. The nearby capacitors have the labels on them, but they vary. The power supply board part # is: PLTVHU401XABV The board location number of the capacitor is C9100 and it is almost dead center on the board.

C8646 and c8646 should be the same as your burnt up one.

C8646 and c8646 should be the same as your burnt up one.

Thank you!! For some reason, when you mentioned those other capacitors and I decided to check, I'm just now noticing the white circles on the board surrounding the capacitors and realizing all the ones with the same circles all have similar specs!

Get higher Voltage rating, I.E. 2KV if you can, the cap is a snnuber cap for Q9100.

Re: Vizio D55un-E1 burnt ceramic capacitor identification

I have the same problem. Not only did the cap pop(c9100) but also the resistor burnt directly in front of the cap. I can't tell the value of it. Can anyone here tell me? I can't read all the board numbers for it because of the burn spot, but can see the number 9111 for it.

R9111 looks like 0.33Ω 1 watt. I R9111 is open, check Q9100 for a short, if the mosfet is shorted, U9101 could be bad aswell

Thanks for the info RJ will check others also.

Re: Vizio D55un-E1 burnt ceramic capacitor identification

I'm OK with finding the resistor but I don't have a clue as to the cap. Can you recommend?
I saw 2kv recommended. I also need to know capacitance,tolerance and I believe it is ceramic. Thanks (I use Digi-Key)

Re: Vizio D55un-E1 burnt ceramic capacitor identification

What I really need to know is the pF or mF. I don't have a magnifying glass to read it.
Thanks

Re: Vizio D55un-E1 burnt ceramic capacitor identification

I don't have a board to check, but similar boards use either a 100PF or 220Pf capacitor

Thanks for the info. and your quick responses.

I use my cellphone camera to take a picture and blow it up to see it.

Re: Vizio D55un-E1 burnt ceramic capacitor identification

Hey fellas, new board member here. Got a guy that lent me his TV to check out. Same TV model number, same board number. Came across this thread and I believe the identification info here helped me some.

I only got one question - what is C9912? I believe this is a blue ceramic capacitor. It is the same or VERY SIMILAR to the C9914 cap and C9913 cap. If I were to read the super tiny text on the cap itself, it would say "SEC 471k SB (+ some random symbols here) and 500v~Y1, 250v~733C". Does this mean it's a 470 pf cap? How do you determine the voltage? 250v minimum? 500v? Trying to find the right component to order off eBay so I can get my board working. Besides 3 other components that went bad/faulty, C9912 was 1 (of 2) that blew and SMOKED the board - left a huge black mark on it - one could say it caught fire, but it did not. I think a power surge hit the board recently... and I think it's fixable as long as I replace the components.

Any info would be greatly appreciated.
Thank you!

Re: Vizio D55un-E1 burnt ceramic capacitor identification

The cap is a 470pf 500v Y1 safety capacitor, the board can be tested without this cap in place. a 470v 250vac Y1 rated safety cap should be ok

If the safety cap blew, I would check if the MOV (RV9901) is shorted as well. If it took a spike to blow these safety caps I suspect there is a lot more damage then a couple components.
This digikey part should be ok DE1B3KX471KB4BN01F

Came here with the same issue and Q9101 has a chip blown out of it so I cannot see the identification numbers. Any chance someone has the data for this IC. All I can get off of it is what looks like "SK742A 439L" The top row of the number is in the missing fragment and I have had no joy in locating anything with these numbers alone.

Re: Vizio D55un-E1 burnt ceramic capacitor identification

can you verify the number, not seeing a Q9101.

[Crossfire351]

Re: Vizio D55un-E1 burnt ceramic capacitor identification

It is a SMD on the back side of the board. I couldn't find it at first either.
Edit: My bad, the ID is U9101, not Q

Re: Vizio D55un-E1 burnt ceramic capacitor identification

I think I have answered my own question.
I believe the part number to be SSC1S311A.

Thank you nomoresonys for responding!

Ok, datasheet there: http://www.datasheet-pdf.com/PDF/SSC...Sanken-1481751
