사용자에게 답변하기: Issue about dry out a iPhone SE that went through the washing machine.Hi @roroeow7 As you know water and electronics and electricity are not a good mix. The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. Rice is good to eat but does not fix the problems caused by corrosion. Don't Put Your Device in Rice. Here's Why First do not turn on your phone and then you need to remove the battery as soon as possible from the phone to minimize further damage. Then you need to completely dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 90%+ (available at electronics parts stores) to remove all traces of corrosion and water. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA Here is a link to the ifixit guide(s) for repairing your phone. iPhone SE Repair Here are a couple of links that describes the process. E...

사용자에게 답변하기: LG 55LS4500 No Picture No sound No standby lightHi @godfather17 Here’s an image taken from the service manual for the TV showing the Power Up boot check flowchart. (click on image to enlarge for better viewing) Here’s a link to the service manual for the TV. To download the file, when the sentence below the Document preview box changes from This file is downloadable free of charge: ...processing... to This file is downloadable free of charge: Download, click on Download as this is the link. Be patient, it may take a little while to find the file. If it is necessary, here’s a link to the firmware (and software upgrade guide)for the TV. Verify that your TV’s exact model number is listed in the Software File reference link, as installing the wrong firmware can brick the TV Hopefully this is of some help.

사용자에게 답변하기: aux input distorted when cable plugged in correctlyHi, Adjust the balance on the audio source (or connect the speaker to an audio source that has this ability) so that you can tell if it is in mono or stereo, when you slightly withdraw the plug from the aux socket. Try full L and then full R to listen if each speaker still works. It may be that there is a faulty aux jack in the speaker. Unfortunately they cannot be repaired but have to be replaced Here’s a link to the ifixit JBL Charge 3 Motherboard Replacement guide, which may be of some help gaining access to the aux port. I cannot find a service manual or a parts list for the speaker so you may have to search on places such as this to try and get a compatible replacement part. Look for 3.5mm phone connectors and then check the datasheets for the component to see if it matches. Hopefully this is of some help.

사용자에게 답변하기: 3.5mm wire code with Blue, green, red, copper, and red & copper wiresHi @phil_a_show , There are two “common” methods of connecting a TRRS jack (click on image to enlarge for better viewing) You may be able to work out which wire goes where by using the Ohmmeter or a 1.5V AA battery and some test leads. I would start with connecting the Ohmmeter across the Green and Copper wires and see if there is a reading or connecting the battery on and off across the same wires and listen for the clicks in the left earphone. If there is then at least you now know the wires for the “tip” (green) and possibly the “R2” or “S” (copper) Next try the same with the Blue wire and the same copper wire and check if there is a reading or a “click” in the right headphone. If there is then at least you now know the wires for the “R1” (blue) and possibly the “R2” or “S” (copper) That just leaves the red wire and the red/earth wire which should be for the microphone. This is where it becomes trial and error whether you connect the red to R2 and the Red/Copper to S along with the other copper wire or con...

사용자에게 답변하기: static only low audioHi, Do you get good audio when connecting a set of headphones to the radio? Does this happen on AM only, FM only, SW only etc or on all the wavebands available on the radio? Here’s a link to the service manual for the radio, which may be of some help.

사용자에게 답변하기: Do you repair laptops?Hi, ifixit does not do repairs. The volunteers who answer the questions on this forum (anyone can ask and can also answer a question on this forum) offer advice on how to repair the device yourself or what is the best thing to do if you can’t. What is the problem with your laptop?

사용자에게 답변하기: Dripper Controller not working in cold weatherHi @creekchub , Heat expands, cold contracts. It may be that there is a dry joint connection somewhere on the circuit board or to the circuit board from the input supply voltage connection. When you heat it up the metals expand and make the connection, when it is cold the metal contracts and the connection is open circuit. Is the controller display showing when it is cold? If not then then I suggest you start looking where the power comes into the controller and follow the paths through. Use a strong light and a magnifying glass to closely inspect the component and wiring connections on and to the control board. Without a schematic (I can’t find one online) it will be a slow process. Try heating only specific areas of the control board to see if you can at least narrow down the area where the problem may be. You could try using a voltmeter to start checking where the 24VAC power comes in and then how far it gets into the circuit before it “disappears”. Trouble with this is that pressure from the meter’s test ...

사용자에게 답변하기: The phone was kind of soaked in a car fluid.Hi @:)hi As you know water (or any liquid) and electronics and electricity are not a good mix. The impurities in the liquids causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. First do not turn on your phone and then you need to with the phone turned off, remove the battery as soon as possible from the phone to minimize any further damage. Then you need to dis-assemble the rest of the phone, including, removing the shields and disconnecting any flex cables from their sockets and clean all the affected parts using Isopropyl Alcohol 90%+ (available at electronics parts stores) to remove all traces of corrosion and any liquid. Do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain scents and is not as effective. If you do check the label to verify the amount of IPA Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted PC...

Hi @captainsnowball ,
FYI
voilà French exclamation - meaning “There it is!” or “There you are!”
The “red thing” in Step 3 is most probably an IR filter, to filter out visible light to improve IR operation
Hi, As yet I haven't figured out how to amend the link to the User Guide for this radio. The one in the Repair Guide no longer exists, so here is one that still works
