Hi I'm hoping someone will be able to help me I have this Samsung PS42A457P1DXXU. I'll try to explain as best as I can. When powered on it does all the usual. Red light goes off it clicks and screen lights up. That's basically it when it on there is no picture although the screen is lit up and the buttons on the TV do not work or respond I have to unplug it then it clicks off and screen goes black cycle is repeated if I plug it back in. I've had the board's off and cannot see anything obvious that sticks out all the caps look ok although one looks like it's been replaced at some point in the past. (Cannot remember where the TV came from) as it's bright blue and the rest are green or black. Any help or suggestions is greatly received and thank you for taking time to read this.

Hi thanks for your reply. Although I am unsure what force test pattern means. I'm fairly new to TVsComment

Re: PS42A457P1DXXU power problems
If you can get pictures of all the boards, there should be a set of jumpers that will produce a test pattern set.Comment

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... -
I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump
One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy... -
