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.
ThanksComment

Hello,
Looking for next steps on troubleshooting for an external power supply made by EDAC, model EA11011H-120. The power supply was dropped onto a tile floor and initially and briefly worked but the led power indicator light faded out and the power supply showed no signs of life since.
In disassembly, I found that the large capacitor had leaked and was reading open when measured. The fuse nearest to the AC in had also blown, with no continuity. I ordered a new capacitor and fuse and replaced both, but on power-up with no load the fuse immediately blew.

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... -
Have a Gigabyte 2070 Super with some bonkers power draw readings. Card runs fine, other than some GPU throttling because of the power numbers. But GPU power always reads too high, more than the power reading for the entire card. And VRAM power always reads way too low, along with PCIe and 6-pin power readings. The 8-pin reading seems plausible.
Typical readout while running 720p Furmark, 8x AA:
GPU clock: 1590 MHz
Mem clock: 1750 MHz
GPU temp: 58.8 °C
Hot spot: 71.8 °C
Fan speed: 33% / 1000 rpm
Mem used: 454 MB
GPU load: 97%

Hi all
There's two other threads about this monitor with seemingly the same problem. The problem was resolved in one case by replacing the entire PSU board and in the second one by replacing an unknown IC.

The first one has pictures of the pcbs and I noticed that there's one IC and assorted caps not populated on mine (but the PCB itself looks identical) so I thought that'd warrant a new thread.
It's my dad's old monitor. He... -
I read through this thread, and just want to confirm what i should do.

This person's fault was exactly the same as mine, even down to the power strip and with the muffled popping sound.
I suspect that my problem started with an old power strip, of which a computer and a 2000W heater were plugged into...
I noticed melting and heat where the heater was plugged in, so i plugged the heater directly into a double wall socket, but still noticed the muffled pop sound when i turned on the computer, and...
