Re: Need resistor help
Try this service manual for the S1 may be similar. Parts list at the end lists R 601 not sure if its the same but worth a try. Oops sorry just realised your first picture had it lol. 620 Ohm metal Glazed 1/2 a watt Resistor. I can't see it being 620 megohm as what would be it's point unless some sort of current limiter.It is an exact value resistor though and must be replaced with original for ensured safety so wait for someone else to chime in.
Someone more knowledgeable might chip in.

Re: Need resistor help
R 507 is near IC 521 on my manual not sure if your board is different Fordman.Comment

Re: Need resistor help
So does your board resemble this Fordman? See Attachment?Attached FilesComment

Re: Need resistor help
No way that resistor is 620Mohm, maybe 62.
Look at the board layout. The trace is big and it sits between the drain of Q601 and D618.
I think it's very low resistance working as a fuse... and it worked... maybe 6R2, looks like the 2 7R5 in parallel nearby...
What are Q601 and D618?Last edited by Dumah Brazorf; 01-04-2018, 03:17 PM.Comment

Re: Need resistor help
Which service manual you get this pictures from for this TNPA5105?

Re: Need resistor help
Got it.
The correct components in the list begin with "R16". So R16601 is 1ohm 0,33W, R16609 is 2kOhm 0,33W as we already know (202, 20 * 10^2)

Service manual Page 68 R16601 is 1 Ohm resistor on that SC board TNPA5105. It is not R601, you have to match the part designator per schematic.
Part list page 104.
The MOSFET is probably shorted out.Never stop learning

Re: Need resistor help
I know it's dodgy but you can test it using a thin wire from a stranded one as a fuse in substitution of R601.
If i'm correct that r601 blows with a current of 0,5-0,6A.
But why also r609 is dead? Check for shorts on that line.Last edited by Dumah Brazorf; 01-05-2018, 02:06 PM.Comment

by TinkerTronHey everyone,
I'm currently working on a mid-70s Sharp Electronic Digital Clock Radio, Model FY-70CH. I found the service manual online, printed it out, and have been studying it for a while. My main reasons for tackling this are: (1) I want to learn electronics and figured I'd start with something I had on hand, and (2) I want to fix its issues. Right now, the radio sounds awful, has about 5V DC at the speaker terminals, and the alarm time setting doesn't work. But I'm not asking how to fix these problems.
Instead, here's what's been bugging me so far:

by artvandalaiThe resistor on this waterpik blew. I changed it with the a similar spec 47ohm 2 watt yageo resistor but it still keeps blowing the resistor. Checking with the multimeter the motor, capacitor, diodes, and thermal fuse all checked normal. Will a higher ohm resistor work better? What ohm resistor will work better to repair this waterpik? This video is showing the repair with a 56 ohm resistor https://www.youtube.com/watch?v=_J7_rV7ui1Y3 Photos

by chth96I have purchased an 100-240v AC/5v 2a DC adaptor from aliexpress,and a month ago It smelled burning when I plugin it powerstrip.
Since then, This AC/DC adaptor have been out of order.
But A few days ago,I replace 0.5 watt resistor with 1 watt resistor(1ohm) in this adapter.
After replacing resistor,It succeed to recharge all of android phone.And When I measure voltage on the two pins of USB port,It shows 5.5v
Is it okay to replace 1/2 watt resistor with 1 watt resistor in AC/DC adapter?
And Is there any possibility that it will suddenly explode as well as to be out... -
by flat-eartherI have a Hoover FM216LI cordless vacuum which isn't charging its internal battery.
I opened up the unit, and it has 6x Samsung ICR18650-22P cells connected in series.
5 cells were at about 3.3-3.1V. one was at 2.4V, so I assumed this cell was bad that's why the vacuum wasn't charging so I replaced it with another 18650, but after that the problem still persists, the vacuum turns on a bit and then cuts out since the batteries are empty.
So I think the over discharged battery wasn't the culprit, it was a symptom of the unit not being able to charge its batteries.... -
by badcap111Hi, while trying to replace a broken screen connector on the motherboard, I knocked off a resistor next to the connector, and the resistor vanished. I have tried to find out the value of the resistor by looking at the schematics, but I cannot find the value. The ID of the resistor, or what you should call it, is R6400.
I don't know if the resistor is necessary for the phone to function, and the connector is still not soldered on to motherboard. I have contacted Xiaomi and asked them if they know the value, but they want a proof of purchase, which I don't have.
