Re: iMac G5 PSU - no power
Okay. I have the identical unit. Let me know when you are ready to go back at this.
The only difference will be I won't get to 220v on mains. Best I can get is ~160 off the transformer. After we are sure the HOT side is not the problem, we should be able to match voltages and readings.

Re: iMac G5 PSU - no power
Hello, recently, I have repaired, an imac G5 power supply (DPS-180SB A), with the symptoms of no standby, totally dead. The power supply, did not have any swollen capacitors on the secondary.
The replaced components have been:
Stand by Ic TNY267PN , a 4.7 Ohms resitor (near this ic), and a 400v 3.3Uf (near this ic an under the heatsink, and covered whith heat shrink), this capacitor have been leaking underside and very hard to see.
First time i have replaced the tny267pn did not work, (a fake ic from ebay), but i have order 10 of them fom ali, and work and a very first try.
I recomend to put a socket from this ic, and check for shorts on the two diodes near the ic.
I hope this helps, thanks for this forum.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... -
Hi,
I've been living in the same apartment for about 5 years now, and moved into it with my old Samsung plasma TV (PS51F5500).
Ever since we've moved in, we would sometimes see strange power-cycling behavior. For example:- TV would randomly turn off then back on.
- TV would turn off and the LED light would blink for a while (over a minute sometimes) until eventually it went back to a regular off state and could be turned on
- Sometimes it would require disconnecting the mains cord from the TV, waiting several minutes, then putting it back in and turning the TV back on. This had limited

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...
