Re: Ryobi 18v BCL14181H MY2015 charger dead
Yea, I have another charger.
But I'd like to have this one fixed. New charger costs less than what I've spent on spare parts... d'oh.

I guess you have replaced almost every component on that charger...?...Leave a comment:

If I remember correctly, they both blink once after the charger is plugged in and then the red led stays on.
Now they are just blinking.Leave a comment:

Changed all the caps. Borrowed the replacement EC6 from another charger.
But still the LEDs blink.Leave a comment:

Re: Ryobi 18v BCL14181H MY2015 charger dead
I was just about to do that, but they forgot to send me the replacement for EC6 1uf/50V. Great…Leave a comment:

Re: Ryobi 18v BCL14181H MY2015 charger dead
At last I had a chance to get back to this!
Spare parts had arrived as well so I replaced some parts, including IC1, Q1 and EC2.
After plugging in green and red LEDs blinks, so I didn't fix it yet. Measured EC2 and it's still 10-14ish volts...
Next step replacing the small EC6 in the secondary?Leave a comment:

Re: Marshall Stanmore Repair
Old thread, I know..
I have one of these speakers on my bench.
Previous owner said it doesn't power up anymore and last time it did, it took a long time before powering up and then worked for a while until it died completely.
I did some measurements like shown on username hann's schematic and found out that 100/63 cap had only 12.3 volts, 3.3/50 had 11.5v, 22/50 had 12.0v and OB2269 pin 3 had 16.68v. Fet drain had full B+ 325 volts. OB2269 looked a little suspicious so I decided to change that and also 3.3/50 cap.

Re: Ryobi 18v BCL14181H MY2015 charger dead
Unfortunately I’m not able to test it for couple of weeks.. but I’ll order some parts and hopefully they have arrived once I get back. Then I’ll get back on ”fixing” this thing.
Next to D2 is EC2 which was pulsating 9-13ish volts.Leave a comment:

Re: Ryobi 18v BCL14181H MY2015 charger dead
Thanks for your reply.
Before I noticed your message, I measured the board live and noticed pulsating voltage on EC2 near D2, it was 9-13ish volts. And on the working charger there's steady 19.9 volts. Something to do with defective IC1 or what else could make it pulse like that?
C9 had 7.41v if I remember correctly, and on a working board it was 15.4v. I guess that filter cap had the same 7.41v....Last edited by SKP; 03-07-2022, 03:56 PM.Leave a comment:

Does anyone have any ideas on this?
I guess the caps are not the problem.Leave a comment:

Re: Ryobi 18v BCL14181H MY2015 charger dead
I probed around on another functioning board and found two SMD caps on faulty board, C10 and C19, which were measuring different values compared to the functioning one.
140-160uF on the faulty and 300-330uF on the functioning board.
Maybe I’ll change them when my spare parts arrive.
All the other components, except IC2 and IC3 which I didn’t measure, gave similar values between the two boards.
With flux, I basically tried to cut corners and get the old solder to flow easily to the pad… bad idea.Leave a comment:

Re: Ryobi 18v BCL14181H MY2015 charger dead
The markings on Q3 and Q5 are now visible, both are 1AM. And they look ok.
While resoldering I managed to burn one of the pads on the EC2 near R9… now it has a very dodgy looking repair, but it works. Maybe my ThermoPasty flux gel wasn't the correct option and that's why the pad got burned, don't know.Leave a comment:

Thanks guys, I'll check the joints. Fuses are ok, forgot to mention it..Leave a comment:

Ryobi 18v BCL14181H MY2015 charger dead
Hi,
I have this EU-version of Ryobi charger which doesn't show any lights when plugged in, but the green led blinks after disconnecting it from the wall socket.
I started troubleshooting by reading this thread [url]https://www.badcaps.net/forum/showthread.php?t=54038&highlight=ryobi[/url] but I guess it is for an older model.
I found couple of SOT-23 mosfets/transistors which look pretty bad (Q5, Q3). Cannot see any markings on them, does anyone know what they are and could these be the reason why the charger doesn't work? Similar components can be found... -

My reply was deleted, I'd guess something to do with a YouTube link.
I sent you a PM.Leave a comment:
