A schematic for this power supply ?

04-02-2018, 07:36 PM

Dear Badcaps Members,

Does anyone know the schematic of this PCB ?
I got burn on R17, replaced it, but still the voltage can not be adjusted ?
Can it be a problem of LM741 ?

Thanks

Re: A schematic for this power supply ?

You should post the other side of the board and someone may be able to reverse engineer it...What is the device?

Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?

by Tynan Dill

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.

Assuming...

Modification to a ZD-987 desoldering/soldering station using a external switching power supply

by sam_sam_sam

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...

Definitive technology SC 2000 subwoofer amp's power supply clicking and popping

by JimBanville

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...

Mid 2014 A1398 MacBookPro,Is it feasible to remove the battery from the MBP and connect it to an external power supply?

by Gust zhang

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...
