Up till now it has been mostly random, when the tv is off sometimes it won't turn on without unplugging tv for a minute, once its on it works perfect, now it has to be power cycled everytime I want to turn the tv on.
Any ideas

Re: Elefw651 needs power cycle to turn on
Do you have any photo's of your power supply. Have you taken any voltage readings?
Photo's of your circuit boards are best since the problem can sometimes be seen.
Is this your power supply?

Re: Elefw651 needs power cycle to turn on
Googling the main board for your model, it is the design that typically has eeprom failures causing issues with turning on. If your standby voltage is good, the eeprom is suspect. https://www.shopjimmy.com/element-el...2-eeprom-only/Last edited by neilc6; 05-18-2021, 09:47 AM.Comment

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... -
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 everyone,
I am dealing with the problem of turning on and off my Dell e7470 notebook.
The battery charge light is solid white, I press the button, the power indicator and the light on the button are solid for 1-2 seconds and immediately turn off.
The system does not turn on, there is no post.
I removed the RAMs and changed them, changed the battery, RTC battery, AC adapter, removed them and waited, tried again, it does not turn on.
The problem continues in the same way.
I tried to turn on the Fn key, nothing came to the screen.... -
