I have a viewsonic monitor that i am tinkering with and my question is can the power input be changed. right now it has the standard power cord type that looks something like you would plug in for a laptop. can this be changed or modified to use a standard 3 prong monitor cord. soldering is not a problem as i have soldered many bad caps but i wand it to use a more standard power cord.

Re: change power input on a viewsonic va912b
Not sure what you mean Monitor has external power supply which connects with a laptop type DC connector. Do you just want to change the connector type or are you thinking of putting a power supply inside.Please upload pictures using attachment function when ask for help on the repair

Re: change power input on a viewsonic va912b
It can be done, but I don't know if you'd feel it was desirable.
The *standard" power socket is an IEC C13, it is physically larger than the IEC C7 on your power brick and the pin spacing is different. Thus there's no room to mount it on the PCB or in the space available in the casing.
It is possible to force open your power brick, take out the circuit board, and mount it in a slightly longer case to give you the free space needed, on which you mount a panel mount type IEC C13 socket then solder wires between it and the adjacent contacts on the PCB. The replacement case will need to be roughly, at least 1" longer than the one currently on the power brick, and it will need to allow for a way to keep the PCB from bouncing around inside since the original did that by merely having no free space for the PCB to move.
Where to find a casing of the same dimensions except an inch longer? That's the catch, you may not be able to find one that's the exact dimensions you want, it could end up undesirably large, or it could be costly. It could end up just as cheap to buy a new power supply rated for same voltage and at least as much current that started out with the IEC C13 style socket instead, then if needed, solder on the right sized barrel plug that fits the monitor's power input socket.Last edited by 999999999; 05-20-2012, 05:34 PM.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... -
HP 15-n070sw (DAOU82MB6D0 REV.D) broken power input. Control pin short with 19V.
Now, after plug power input led power button & power blink 13 times and light led power socket I start the laptop but no picture on screen only backlight light. The external screen connected via hdmi does not display either.
I'm now wondering if a short circuit in the 19V socket could also cause the lack of image on the screen. Please rate and tell me what 13 flashes of the power LED mean.
