What capacitance and voltage rating is printed on C605?

C605? There's nothing there. Did you mean C603?Comment

C905, sorry. Reading upside down is hard.
Did you reinstall D902?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Ah. C905: Looks like 50v; 1 microfarad.
Yes, I resoldered the leg I pulled up.Comment

Re: Sanyo DP42849 - No Power At All
C905 is only 1uF/50V? That is quite big for that volt/capacitance rating. Is that C902 maybe?Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Double checking . . .
C902 is 50v 22uf
C905 is 50v 1ufComment

C905: .02 -->.06

c603: ~.01 --> ~.01Comment

Re: Sanyo DP42849 - No Power At All
So, it looks like D903, a little SMD diode on the bottom of the board, is a potential candidate. It's near C905. This develops the supply voltage for the main switcher IC. It is possibly open circuit, which could be caused by a short, or the initial failure.
Can you get a picture of the area around this diode - I need to be able to see where all the traces go into this device.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Sanyo DP42849 - No Power At All
That confirms my hunch; check D903 is not open circuit. Also, check on 2000 ohms across that capacitor C905 right next to it (allow reading to settle for 5 seconds first.)Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

My fault for not checking. Can you see any part # on D903? Could just be a few letters.Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!

Re: Sanyo DP42849 - No Power At All
There wasn't much I could do without internet anyway, so I didn't mess with it.
Looks like 5p. Might also be 5D. It really looks like a 'p', tho.Last edited by NihonNoir; 02-10-2014, 07:41 AM.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 gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.
On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off... -
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...
