I just inherited a nice looking Samsung 55, but it's got no power, no standby light, nothing. Pulled the cover, and the fuse above the power connector is blown. I tried jumping another fuse to it, blew instantly. I'm a backyard, shadetree tinkerer at best, and don't have oodles of gear or experience. Am I best off to send this board in for repair, buy a replacement, or throw in the towel?

Re: BN44-00503A no power
Shopjimmy do a replacement power supply for $69.95 or repair kit for $18.77 but you would need to be able to solder small components if you purchase the repair kit.

Re: BN44-00503A no power
Never, replace only the fuse and power up the tv.An over current happened that blown the fuse out.Probably, you have one or more shorted components, i would start by checking out the Mosfets and the the 3 pin diodes ( TO package).Comment

Re: BN44-00503A no power
Well above my pay grade on this. When I retire in about 10 years I fullwell plan on learning my way around detailed repairs like this, but for now, there's just too much work to do on the new house in my free time. Safe to say it's the power supply board? There's an ebay repair service listed for this board. I also thought about buying a used board, but if this is a common issue I'd hate to buy one and have it fail a month later.

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 gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
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...
