update 2:
worked like a charm. not sure of the potential repercussions from bypassing the two components... any thoughts would be appreciated. But for now, its working as intended.

Re: xbox contoller elite original model 1698
Update:
i know this is pretty generic as i microsoft doesnt have info available for this, so lets generalize a bit and you guys can fact check me.
capacitors to ground:
in my experience, this is generally just filter caps for low impedance to ground for voltage on circuits. my thought that if one is missing, depending on the scenario, it really wouldnt cause an issue. if a wire is jumpered, nothing lower impedance than a direct path no? share thoughts please
tvs/esd diodes:

xbox contoller elite original model 1698
home repair attempt, replacing left and right thumbstick joysticks.
client lost d27 on right thumbstick joystick circuit and c26 on left thumbstick joystick circuit.
cannot find diagram or board view for values, if anyone knows, please post.
upon tracing the circuit, c26 goes to ground on one side and the other disappears leads through a circuit with several veers and finally makes it to the main controller chip.
question: since it goes to ground, do you think that it is necessary or can i just jump a wire and it will be ok?

Re: What Are These Resistor Looking Componenets?
update:
double checked the motor. there is only one, central, raising and lowering the tv mount from cabinet. motor was not seized up from my checking.
plugged everything up and worked like a charm. the n channel mosfet and the main cap was the only things blown and replaced. ill chalk it up to old age.Leave a comment:

Re: What Are These Resistor Looking Componenets?
i will look into a second motor in the cabinet, but i only saw one when i did my initial inspection. im going monday to fit and test the progress so far. until then, nothing really more i can do.
thank you all for the input thus far, i will update on moday....Leave a comment:

Re: What Are These Resistor Looking Componenets?
perfect.. that explains the non function for now. i will hook it up to the motor and see what happens. if it blows at that point, i know its the motor itself and can move forward. if it doesnt, then ill chalk it up to the bad components. if it still doesnt move down after moving up, ill swap the relay and double check the diodes in that circuit. as for now, it seems fine....Leave a comment:

Re: What Are These Resistor Looking Componenets?
Replaced the fet and the cap. controller works. depending on how this controller is set up, i believe the cause was a bad relay. the up function clicks when pressed but nothing on the down. the controller is powered and holding however.
so, either this means a bad relay of sorts, that possibly shorted out the circuit while it died and now has no affect as it still holds current fine,
or,
the controller recognizes a memory setting of sorts that only goes down after fully locking out in the up...Leave a comment:

Re: What Are These Resistor Looking Componenets?
yeah its a toroidal... tto-12493-01... got 3 fuses. my parts arrive today. gonna fit components tomorrow, ohm out for any shorts again to be safe before applying transformer, check for shorts again, then apply power to the controller. if it holds, im going to move on to checking out the motor itself. make sure it isnt seized up. if it is, ill remove the fluid and see if i can free it up. if its good, ill just hook everything up and see whats what.
i dont have the motor here with me, just the controller.
ill...Leave a comment:

Re: What Are These Resistor Looking Componenets?
i thought that perhaps the motor seized as well. Havent been able to test yet but will be applying direct current to the motor once i recieve my male adapter and mak a pig tail for my dc power supply. its a 6 pin s plug from the motor to the control box, h,n,g for up and h,n,g for down im assuming.
the out put 1 from trans goes to the plus on the board that the mosfet blew. The output 2 seems to trace to the big cap that blew on the anode side. there are to white wires that insert via connector, im...Last edited by jostewcrew; 08-19-2020, 06:43 AM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
yes 2 fets.
sure, any pointers on how you want, what you want to see uploaded? its ac in, converts to dc, and pushes a dc servo motor for a hydraulic lift. up and down functionality.
let me know exactly how you want to see and what, video, pics...ill upload tomorrow....Last edited by jostewcrew; 08-18-2020, 11:00 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
both resistors are connected to the source of each mosfet.
the + is output 1 from the transformer, connected to the gate of the mosfet that blew, then through a diode to the resistor that looked burnt but still reads within the tolerance found from my searching earlier. diode is still good as well. im thinking that it was just a bad fet.
the main cap that blew traces as a part of the output 2 from the transformer. (anode side) this is why i was initially thinking that the transformer...Leave a comment:

Re: What Are These Resistor Looking Componenets?
that makes perfect sense... thank you. so this is in fact a wire wound fusible resistor. i was pretty sure from earlier but this was the icing on the cake. thank you good sir.
initially, i also thought it was a current sensing resistor as there are two separate circuits , fet followed by these resistors, that only combine on a line leading to an ic. (only the one end of the resistors meet on this ic line) but i realized although this was possible, it was more likely a fusible, low ohm resistor for protection...Last edited by jostewcrew; 08-18-2020, 07:42 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
finally wrapped my head around what i was reading, from help here and online. the color body means nothing (manufacturers use different body colors depending on whatever theyre trying to notate within their own realm of components)
with what ive gathered, these are modified, four band , wire wound, high precision resistors with a fifth band notating the energy coefficient.
thank you budm for your insight and assistance.

Re: What Are These Resistor Looking Componenets?
again, i realize i cant use the standard color code for bands, but since i have no data on what these bands mean... im trying to make sense of it. where are you getting your denotations from? ive searched google for hours and it just keeps coming up with the same standard crap. how do i find out what the bands mean for these...
im 100 percent sure on the color schemes ive listed for the one with red and yellow. the all black one may actually be black,black,gold,brown, black. they measure .3 ohms a peice even though theyre...Last edited by jostewcrew; 08-17-2020, 07:18 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
right, i got that its not the same, however ive yet to find a chart that lists gold or siver, (third band on these) that gives any value. calcs wont accept it so i need a chart, but it refuses to give values for these colors other than multipliers.
so if its black, black, gold, black, black
or
black, red, silver, yellow, black ...
im still lost in values other than knowing that the 4th is tolerance and the 5th is temperature coefficient. or am i still not understanding something?...Last edited by jostewcrew; 08-17-2020, 06:09 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
yeah, i didnt expect to be able to get any tracing done...thats all on me, though i appreciate the thought. i just wanted to figure out what and what value those resistors were. still even with searching for nox color codes, they dont match what it is showing me.
im probably going to just order what i can and then find another box for parts and test between the two. im sure i can get a working control out of the two. thanks for the light bulb trick... ill make sure to utilize itLeave a comment:

Re: What Are These Resistor Looking Componenets?
Uploaded front side and backside of board. Back side orientation is flipping front side over from top down.
this is a control box for an old liftbox, hidden tv in furniture type deal...out of business for like 6 or 7 years...no service man or schematics i could find. it controls a tv stand that sits in a dresser...this box is the power source for the lift motor and the relays for the ir remote and such. the box had power, 120v in and out for the tv plug. but no function of lift. open up the box and see the cap and the...Last edited by jostewcrew; 08-17-2020, 04:19 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
Not in parallel. you are correct with the layout. both are on the source pins of the fets on separate circuits. both resistors meet to chat on a circuit that seems to lead to a 14 pin ic.
so if they are good, ill just replace the one cap and the fet. everything else tests fine. just wanted to be safe...but was becoming a headache tracking down the resistors....Last edited by jostewcrew; 08-17-2020, 03:19 PM.Leave a comment:

Re: What Are These Resistor Looking Componenets?
the bands are as follows for each:
black, black, gold, black, black
black, red, silver, yellow, brown
i tried using many color chart calcs and they wont allow these colors. any link to a page with a chart?
they both show .3 ohms on the meter. the black and gold one is on a circuit that blew the main cap and mosfet. im changing the other circuit components for good measure.Last edited by jostewcrew; 08-17-2020, 02:57 PM.Leave a comment:
