yes-Pins 110vac and 50vac should be measured in alternating current.
If 5 volts do not appear on pin BL, then there is a problem on the motherboard.
to check the operation of the backlight inverter, connect pin 5v with pin BL via a resistor with a nominal value of about 1 kOhm -
Some body can help me?Comment

Hi, measure the voltage at STBY to startComment

pin 5V =5v
pin STBY = how many ?Comment

?Comment

When you turn on the TV with the remote control, how does the voltage on the pin STBY change?Comment

standby has around 3v when I turn on the tv.The problem is that the standby leds make 2 flashes and then the TV turns off.When TV tries to turn on there is no any image and there is no back light, however there is 90v in the LED backlight + cable but there is no - in the LED backlight cable.I have my doubts about using this power board, for that reason I want to turn on this power board without the main board connectedComment

In the last photo, the pin table CN2 is not completely visible.Comment

The measurements I have made so far have only been in cn3Comment

you need to check the serviceability of the backlight, apply a voltage of 200 volts with a current limit of 250 mA, red wire is positive, yellow is negativeComment

ok
how many volts when turning on the TV on S2001 between pin1 and pin4Comment

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... -
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... -
Hi All,
Need help.
I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.
So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....
