Re: power board whit cap missing.
Might help to know what it's out of.
What makes you think there was ever a cap there?

Re: power board whit cap missing.
thanks for the fast response,,and very sorry for the lack of info,,the power board is for a daytek lcd tv model:LTD32UB and some other tecnhician took away the capacitor and the customer brought to my workshop the TV set.The tech made an arrangement of two capacitors,but they where so small, 5 micofarads 350 volts..and I suspect that there is no room for that smalcap..thanks..Comment

Sorry, I can't find anything on that one.
Hopefully one of the 'screen guys' will wander in and has seen one.Mann-Made Global Warming.

Re: power board whit cap missing.
en esta pantalla veo que hay muchas fallas yo tengo una igual y tengo el problema de que no enciende solo enciende el foco del stand by .
estoy tambien tratando de repararla . ese mismo filtro o capacitor ya se lo habian cambiado le habian instalado 2 filtros de 22microfaradios a 250wts en serie . lo lleve a un taller y me le instalaron este que es el mas proximo a los valores que le instalaron en serie. espero te sirva esta informacion . mi tecnico me comento que ya los voltajes estaban bien solo que sigue sin prender la tv me comentban que era una problema de la tarjeta main . x ultimo ya estoy cansado de no ver resultados . te podria vender toda la pantalla debido que dicen que ya mi fuente esta bien solo es la tarjeta main .
o te puedo vender la pura fuente . si asi lo decides . soy de gdl jalisco y una perosna seria y comprometida si no te sirviera se te regresaria el efectivo .
x ultimo prueba con ese filtro . ojala y te funcione . si surgiera otra falla te dejo el siguiente link

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.

Hi and thanks in advance for any input you might provide!
I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO
Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this... -
Hi everyone,
I am trying to fix a samsung washinmachine power supply main board.
I already replaced it with another one to fix the machine but i want to try understand the issue with the old board.
Therefore i hope to be able to get some help to explain what to check in order to troubleshoot.
The power supply board reference is the following: DC41-00189a
I have followed one thread (https://www.badcaps.net/forum/troubl...ingmachine-rel... -
I did not have any 27uf @ 50 volt capacitors but one nice thing is that it has enough room for two capacitors in parallel a 22uf and a 4.7uf @ 50 volts 22 plus 4.7 equals 26.7uf which so very close to 27uf I will show some pictures of it sometime tomorrow
This is one of the shit est boards I seen in a very long time and it was the daughter board the traces just lifting off the board I had to use the capacitor leads to repair the the traces and the main board is not any better because I had to repair several traces for the daughter board to the main board
After all of... -
ONN 100012588
Issue: No Power, Then Rebooting After Main Board Change
Short answer: replace main board and power board
Technical answer: replace main board and Q306 & Q307 on power board.
Long answer:
TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....
