I Have a Element ELCHS261 that has a red power light when plugged in, but nothing when you press the power button. I've tried using a remote as well, from what I can tell there aren't any bulging caps or leaks.

Re: Element ELCHS261 Doesn't Power on
Briefly looked for a service manual with no luck. But check for your voltages at P1 on the main board, there's a pin labeled on/off maybe it's not getting the signal, check for voltage there when pressing power...Comment

Re: Element ELCHS261 Doesn't Power on
Since this combo board has PFC Voltage booster circuit, you need to check the DC voltage on that large black DC filter cap in the primary (hot side) of the power supply. Check it with the TV plugged in but do not hit the power switch, the DC on that cap should be about 165VDC, then hit the power switch, the DC voltage on that cap should rise up to around 390~400VDC, if it does, that means the main power PS_ON signal is OK. If it does not go up then it may mean that PS_ON is not present or the PFC circuit is bad.Never stop learning

Re: Element ELCHS261 Doesn't Power on
The power board also mentions that there are two expected output voltages - 5VDC and 12VDC. Read all of the voltages on the output connector. Some of these will not be there until the unit is turned on. There should be a 5VSB and some others. Use the GND on the output connector when taking the readings.The strong-minded rise to the challenge of their goals,the weak-minded BECOME HATERS

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 all!
I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅
I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

Hi all,
TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!
I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!
A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about... -

Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...
