I have a PC power supply and I know there is 2 pins you need to jumper if wanting to start it not hooked up to a computer.....anyone know how to do this?

Re: starting a power supply
Connect green wire in the ATX connector with any of the black wires. You could've easily found it on Google.A working TV? How boring!Originally posted by PeteS in CA -

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.

I have been working on this concept for quite some time now with limited success but recently I found a switching power supply that is setup for the voltage that this soldering station needs to operate at however it also needs part of the secondary circuit from the original switching power because you need several voltage rails
I once tried to get a ZD-915 desoldering station to work on a 18 volt battery power supply but unfortunately things did not go well but I did find a work around but I might try this idea again but going at a little differently more about this another time... -
The sub developed a constant popping every couple seconds from woofer and power LED flickering with nothing but wall AC connected. Connecting an audio cable didn't change anything. It doesn't play but a second or two of audio in between the pops.
Opened it up and discovered the power supply is making a faint clicking or ticking sound.
I measured the amp's output to the woofer and it pulses up to 50mv DC to be driver. The pulses coincide with the power supply ticking/clicking.
I measured the power supply output going to the amp board and it too has this pulsing. Voltage cycles... -
I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem... -
Hello!
i got a damaged Manson NTP-5561 (60V, 1,6A DC output) and and the main issue is that the controler IC for the LCD display has a short. The controler IC PIC18F87K90 is mounted on the back of the back of the LCD. Vss-Vdd = 3 Ohm. The 5V and 3,3V power line was killed as well, but that is not a problem. A new LDO 3,3V and 5V 7805 is already ordered.
Replacing the PIC18F87K90 is necessary but that makes no sense without having the HEX dump of the new controler.
Does anybody have such a power supply and could do a HEX dump of the Flash and EEPROM memory?
