Re: Vizio standby light but will not power on
Do you have the serial number of the main board? A photo of it would be nice also.

Big storm, terrible lightning, big boom, lights out no power, power back on standby light showa yellow but TV wont power on. NEED HELP!!!! I would like to fix this myself. research on YouTube gives me the impression that it can be done. Would like feedback from professionals. I do not have any tools tho so I Im curious if I were to take on this task what would I need for the job????Comment

I have a Vizio E550i-A0 that will not power on. It also does not display the standby light in the corner. I disconnected the main board cable to see if the backlights would light but they did not (maybe this is normal for this set?). I checked the voltages on the plug and they all read in mV or 0, so there's no voltage there. The fuses are ok, and the voltages of the 450v caps read about 160v. I see no visual damage on either the power supply or main board. I have read online that the main board is usually the culprit in this model, but not getting backlights with the main disconnected makes me... -
Hi everyone,
I'm trying to troubleshoot and repair this old LG OLED curved TV, model 55EG910V.
I did some basic troubleshooting and reviewed most related posts here, but I wasn't able to isolate the issue.
The TV shut itself off during playback and never came back to life - the standby light remains off. My dad claims that it has happened a few times in the past but the issue resolved itself after some time. Not this one.
After checking the basics I did the following:- I measured all voltages and as expected the only active supply is the 3.5V standby. It

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.

Hey All,
I have a Sony 65x900f that I purchased cheap because of a no-power issue.
I assumed that because there is no standby light visible, it would be an easy fix - however upon opening up of the unit I can confirm that the 3v3 standby voltage is making it's way from the power supply to the main board. I'm a little confused as to why there is no standby light.
I am firstly wondering if anyone has this model of TV, or has worked on one and can give me some insight. I have tried to find a service manual for this model, to no avail - and would really appreciate... -
No standby red light, nothing
This Sony has a separate AC->DC power adapter supplying 19.5V to the TV power board (JK3)
Disconnected JK3 power board from main board, checked voltages on all the pin outs
At a few pins I can see the power supply providing 19.5V to the main board
Based on the service manual triage.. it seems to be pointing towards the power board (JK3) being the most possible culprit
LED light turns on when I disconnect LED driver board ribbon from mainboard (so i thought it is the mainboard,...
