That’s gotta be glued in with something. Geez… drilling at it for 2 hrs and still no go? Something is holding it tight.

It could be, but I think Petehall is right, I'm using stainless steel drill bits, trying to drill hardened steel, not getting anywhere in depth because of wrong bit, going to try some carbide bits. The darn set screw is only 3mm in length. When I take bit out and measure depth, I'm not even half way. I'll keep at it, till I get it off, may take awhile. I think I'm a little to far gone to try a left hand drill bit.Comment

Yooo… stainless steel drill bit? May not work very well. Cobalt would be better but hardened steel is hard to drill.Comment

I ordered a set of carbide bits, should be here sat. Has anyone had this much trouble with this, or is it just me. In the mean time I'll go back and double check everything, I've done so far, with the components. I'll list all the bad one's that I found. I want to recap the unit, as an ultimate goal for this amp. I've been extra careful not to enlargen the small set screw hole, while doing this, it's at an 1/8in, just a tad larger than original hole by a 1/32, wanted to make sure I got the hole grub screw out, so I can re tap. Have a great weekend guys,and thanks for hanging in there with me, much appreciated. Maybe we can get back to fixing electronics instead of farting with drilling shit out.Comment

Troubles? Today at work I felt like I was surrounded by pussytouch idiots.
Hope that makes you feel better now.

All better now,unfortunately, we have alot of them, I call them entitled little bioches. Glad I'm retired, I couldn't, and wouldn't put up with that shit for to long.Comment

Carbide drill bits arrived, I have a mini camera that I'm going to try and get a peak under that knob, and see what's holding up the removal. Drilling blind sucks, and could cause too much damage. I'm going to see if this will help see what's going on. I'll post those bad components this evening.Comment

Well got a few more components to check, and I will be ready for a dim bulb test. Hope for no light, and good working amp. I will also list, all the damaged components I found. There wasn't as many as I thought 6 or seven, but I replaced alot, even if they were good. Caps, transistors, a few resistors, that were bad ,or burned up dark looking,but still working.Goinf to post some pics as well of the board.Comment

Haven't seen anybody on here responding, Cap, you still with me. Pete you still here?Comment

Here are the components that were found to be bad. First the two output transistors near Q11. The two were completely dead no readings at all when removed. Q11 was deemed to be ok, but with low readings. It was changed, as was all the rest. Q10, Q9, Q12. Q9 also tested ok ,but with low readings. Next were resistors R23, burnt black, open no reading.R1as well. R3, 21,5,19,6 were all dark and replaced. Transistor Q5 was dead as well as Q1. I replaced all 8 of them anyway. All caps were replaced, one tested bad, C 6. Those are the components that were found to be bad. I replaced all 4 output transistors to keep things even. I want to check a few more things before I use the dim bulb tester. I will post some pics of the board as well.Comment

Yep, still here... just didn't pay attention as I got busy with other things and events at home. Working on a 160pin IC for a entertainment / control system for a BMW X5 right now.Comment

No... I was about to fiddle around with the programmable input and output pins, dragging them into the opposite direction on the ATMEGA and see if something changes on the blue LED or on the gas valve. I was hoping to find a problem with a pin, then backtracking the circuit. Then I was on the road and never made it back to the welder.Comment

Guess what I got done in a few min, with the correct tool? Yep it's off no damage, now to retap.Attached FilesComment

Oyyy…. What tool did you use?Comment

Hi, 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... -
Hi 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... -
I 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... -
Hello 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 -
Hello 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,...
