Yea, I haven't got much done here, I still have a few components I want to check out before I test. Father's day weekend coming up too. Probable get back at in a few days. I hope you get all your work done as well. Have a great evening.Comment

Yea, I can't wait , my daughter makes a fantastic steak , and shrimp. Wash that all down with a cold one. Relax! That's my plans. Get out that grinder, and file, sharpen
those blades, makes it easier on you, and that mower. Have a great Father's day weekend. I'm going to get a few more components this afternoon. I'll let ya know what I find.Comment

Steak, and shrimp one of my faves.Daughter does it outside camp style, open fire, baked potatoe in fire, so good with Ice cold beer. Did you get any vibration with those bent blades.Comment

You're welcome to anytime. Plenty to go around. Bring my favorite with you, some Crown Royal. I got a few things over the weekend done. Replaced some caps on the Power supply, and a few that have that corrosive glue all over the place, mostly the big caps. Some on the control board. Then re check the components we changed, then I'm testing on dim bulb. Praying for a successful test.Comment

Do you know if the tester I use, can test components in circuit? It's the FNIRSI.Last edited by rccrasher65; 06-16-2025, 10:16 PM.Comment

Yes,I just did a little more research, and no, all components must be out of circuit, reason I asked I wanted to check those white plate resistors behind the 4 big main filter caps, hard to get anything back there. I'm not suspecting any damage, but just want to be sure!Comment

Yea , every thing is packed in pretty tight, just behind filter caps, and heatsink. I have a pair of long clip on grabber leads, so I think I'll be able to get at them. If not I'll just remove the caps , and replace them now , instead of later.Comment

I have the caps, I guess I'll replace them now, makes things so much easier. I'll have to delay the dim bulb for a few more days, getting anxious now. I'll have some pics of my work as well. When I'm done that is.Comment

by jm1234Hi, I'm seeing one 9V relay having temperature 40C on its 9V (primary) side. Does that seem right? I switched 2 relays on that board and the temperature was the same (on the same position), so I'm sure it's not a faulty relay. I measured voltage on that relay and it was 9.5V DC, so that looks good. I don't see any other relay on that board having that kind of temperature and they have 9V on them too.
I thought maybe the transistor that is switching this relay keeps switching on/off, so I also checked for AC and there was almost none: 0.3V using mV range. No steady frequency was shown, but... -
by edugimenoHi everyone!
I have this board that suddenly stopped supplying power to an output that drives an interchanger cleaner motor.
I checked while the board was in place with all wires attached and there's no AC voltage on the corresponding plug X5
This X5 is driven by fuse F8 (tested OK) which comes from the second orange relay
To make sure there are no charcoaled contacts inside the relay, I got a 24VDC power supply and got it ready to manually power up the coil side of these relays.
I respected the polarity, positive to cathode of protecting diode
So provided all... -
by sam_sam_samI was working on this CNC machine today found no keyboard functioning no control relay powering on
The screen powered on and was giving an operation error but the manual was not very clear about what the error exactly was but with a little bit of troubleshooting and finding out that the control relays not powering on and no keyboard functions we narrowed down to this one switching power supply which of course does not have any indicator LED light they are on the keyboard interface/relay controller board
Found shorted diodes on main controller relays there are 3 of them that... -
by DXseekerMOHello everyone!
Recently I've noticed that some ShopJimmy backlight strips don't have double-sided tape installed upon them when an application calls for it, and I must purchase the tape separately. In a recent chat conversation with a customer service agent I told them if this tape wasn't applied when it was called for I would begin to consider ordering my backlight strips elsewhere. It looks like this time may have come.
I recently got a TCL 65S4 with bad backlights. After looking at the SJ listing here: https://www.shopjimmy.com/tcl-jl-d65...365as-m-led-ba...Yes0%1All backlight strips are the same quality0%1No0%0 -
by malogroHello all,
I'm stumped on this guy, so wanted to see if anyone has any further ideas:
Intro:
This is an Acer Nitro 5 AN515-55-55M1 with unknown prior history (bought "as-is" on eBay). It charges the battery and powers on from both AC adapter and battery, so I think this rules out main power issues.
Upon attempt to boot, it will "reboot" (meaning powers down and then powers on again) only once, and then stays stuck in a status of lights on / no post / no monitor. Powering on with fn+esc maxes out the fans on first boot attempt,... - Loading...
