Retired Caps:
Thanks for your quick response.
1) With a working pc attached and as bright a flashlight as I could find, there does not appear to be any image on the dark screen.
2) The "Please Wait..." stays on for a mere second.

Re: AOC Envision L19W861 failure
What caps did you use as replacements?

AOC Envision L19W861 failure
Being the newbie here, I have looked all over hoping someone else had the same problem I've had. This RadioShack unit worked fine for about 2 years as a closed-circuit tv monitor for a security system. Then one day it just went black. I replaced all the caps (except the largest dog on the field) and all I get is the power light flashing red when I plug it in. Upon hitting power (on board or remote) the red flashes about 6 times and turns a steady blue. The monitor flickers, displays the usual "Please Wait..." and goes black. I have check and rechecked solder joints, wiring, plugs, etc. The unit is 3 years old and is good for nothing but a paper weight right now. Any ideas??? Please?Attached Files -

I am trying to repair an LG split AC indoor unit, which does not start and gives a CH05 error code.
This indicates an error in the communication between the outdoor and the indoor unit.
The outdoor unit is fine, so the problem is the indoor PCB.
The indoor unit is an LG PC09SQ NSJ (3SNM09JA2FA), and the PCB has the following type number: EAX35907219-1.2 (see photo1)
I changed optocouplers ICO1X & ICO2X and the NPN transistor S9013 which drives optocoupler ICO2X (see photo2), but this did not remedy the fault.
Does anybody have the schematics of this board,...02-01-2025, 12:55 PM -
Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish.... -
Yesterday I successfully repaired a Middle Atlantic UPS2200R-IP that had inadvertently been used as a surge suppressor at our transmitter site. It has already been replaced with an updated one but it's coming home with me now instead of being e-cycled. To be specific, this is the MA model that has the blue backlit display and has been discontinued, although this design may have been used in many UPS units including the smaller Middle Atlantic ones in this series.
Here's what happened: We experienced a brownout/surge at the site, which damaged the UPS and took our broadcasting... -
Hello everyone,
I'm turning to the Badcaps community to help me troubleshoot the radio Rx card from my (old) garage door opener. While I could just ditch that card and replace the whole system, I first would like to understand "why" it suddenly stopped working, because that's just how I am wired...!
Some basics: the receiver works on a 30.875 Mhz frequency. Yes, I'm aware this is not in use anymore in a looot of places. It does not use any rolling code, it's just a regular dip-switch code that you have to set up on both the receiver and transmitter. The receiver... -
I have finished my work. The new lights come on except the one for stereo, I reversed the bulbs to no affect, anyway, the unit powers on, relay clicks. I have no DC voltage in speaker outputs, I also do not have any AC in the speaker outputs. There is some faint crackling in the speaker. This unit cranks up loud so I had the volume on very low. Everything seems to be fine but I can't really check the switch until I can get sound out of the outputs. I was going to do caps for the power supplys and the tone board but thought if it was cranking loud at one time maybe just leave it alone until it...
