Hi guys, I have this wifi extender from 2 years ago. Itstarted to hhavesome problem like ddisconnectingalone and reconnect alone some time I must turning off wait a couple of minutes and open it to working again, anyway I opened and found some capacitor not very good then I replaced, and this kind of resistance.. It's possible I can't buy it? I mean I read the mark on the pcb but I didn't find it... It's very strange that or the problem is myself getting badly research... thank you all for your reply , your time and your help 🙏

Hi guys I have news, I received the resistor, but as you can see it is more larger than mine, anyway I was to try but when I plugged it just brown up. Do you think I may put this thing on the bin ? Because I can't find it the exactly resistor... thanks in advance2 PhotosComment

It is some sort of a high wattage low value resistance resistor in the power section. It is probably used as a fusible resistor. So my guess is you got a shorted something in there that needs to be found before you replace that resistor.
The larger wattage (bigger) resistor shouldn't be a problem. However a smaller that the original one is a problem. Of course best would be to gat the same size (wattage) resistor, but if 7.5 Ohm 3W was written on the board, it is fine by me. Just be mindful of replacing parts, because it is like you you put a 10A fuse in a 5A circuit.

Thanks man but the thing was working before I opened it. Some time it just slow down the connection.. So I opened and found the resistor no so good.. It's really strange iI already checked those capacitor and the bridge rectify they are okay. Maybe the resistor that I buying is too big? ThanksLast edited by labello; 07-21-2024, 12:17 PM.Comment

To me: if that resistor blows, it’s lights out.Comment

The smaller is the original, as you can see looks no so good... So I buy it following the mark on board. But it's too big than the original one. I'm guessing if I replace again the resistor and plug in the lamp limiter? Thanks for your help 👍2 PhotosComment

Then the cap should go poof!
Right now my bet is you got the wrong resistor type. The original is wire wound and you replaced it with a carbon composite type. Stick another wire wound one in there.
measure the original resistor with your ohm meterLast edited by CapLeaker; 07-21-2024, 02:12 PM.Comment

Possibly, I order 7.5 Ohm 3w just mark says. I measured the original with multimeter ( selector ohm) t's open circuitComment

Yes I think so, il check it after the work day,but I'm afraid I can't find the same resistor. I just do it but it's different. So I suppose the seller is the liar ..?🤔Comment

Have you measured that M7 diode ( D10002 in your picture ) ? Also, trace where the resistor is connected.Comment

I think you may be on to something. Question is did the black cap get removed and soldered by accident back in backwards, or are the markings on the PCB wrong (I’ve seen that before too). Hard to tell without seeing the board. From both sides.Comment

Guys both of you are right! The black capacitor was in backwards (soldered in the wrong direction by someone) I changed the resistor again with a new one and put the capacitor in the right direction, and then it works again!! Your guidelines was so helpful I almost put it on the bin. Thank you both of you!! One more questions why the original resistor is different against the new one? Is something that I must understand? ThanksComment

by howardc64Thanks to Diah, got M557-G0 LCD panel buffer board repaired and running ( link ) Next challenge is no WiFi/Bt despite module on the main board and getting 3.3v supply (3.45v measured)
- TV Menu shows Network Access Point option (enet unplugged) but menu can't select that entry
- Service Menu shows many Bt/Wifi info missing
- Vizio app shows no WIFIVendor file
- Tried countless enet unplug (user manual said need to unplug enet to get to wifi menu), factory

by ugamazingI've got two boards with the exact same issue, and it's confusing the hell out of me. In short:
1. Both boards behave *exactly* the same; they will show WiFi networks to connect to, and will boot fully to Internet Recovery, but they each show zero available WiFi networks once booted to Internet Recovery. I also cannot switch WiFi "off", as in, the toggle will not move.
2. Both boards will erase perfectly fine using the "erase mac" function; I can wipe them with disk utility, but if I try to install MacOS from Internet Recovery, it says to connect... -
by AlexVGHi,
I have had an iROBOT i7 with a camera error (error 68) version REV M, year 2018.
I bought a liquid damaged Mainboard with WiFi module, from the same vacuum cleaner, but a different year and a different version (REV G).
(This board does not respond, only the LEDs light up in a circle.
The liquid damage is catastrophic and restoration is impractical).
(I bought this board to get the WiFi module and camera).
The boards are completely different in the installation of elements, even the connector for the WiFi module is different.
