Hi @kas_boot , Not sure but this is either the GSM antenna or the WiFi antenna (supplier example only to show what it looks like). The part number is GH42-05890A. The part location can be seen ~3:00 minutes into this video. Hopefully this is of some help.

Hi, Here’s the hardware maintenance manual for the laptop. Go to p.46 to view the necessary pre-requisite steps and then the procedure to remove the fan and heat sink assembly. If the fan is faulty and needs to be replaced the part number is 90203127. Search online using the part number only to find suppliers.

Hi @nikluv2020 , Does the new pump just hum as well? Have you got a DMM (digital multimeter) and know how to use it when testing for lethal AC voltage? If so measure the voltage at the drain pump terminals to check if the full voltage is being applied to the drain motor during the drain part of the cycle. If not, perhaps you know someone who can safely test it for you. Be safety aware when testing as the voltage will be at mains supply value i.e. 120V AC.

Hi @josejrosas , Search online for BA39-01338A to find suppliers that suit you.

Hi @ margaret boatemaa Go online to your mobile phone service provider’s website and search for the sms/mms settings for the phone. Each service provider has different settings so you need to check the service provider which supplied the SIM card for your mobile phone service.

Hi @ceebeegeebee , You can check if the discs are spinning or not by inserting a disc and remembering what position the label was in and then allow it time to check the disc and then eject the disc and check the position of the label to see if it has moved in relation to what it was when it was first inserted. Has it worked OK before when inserting the exact same discs? If it hasn’t, check that the discs are compatible with the player. (see p.8 of the user manual) If it has then here’s the start of the test mode procedure from the service manual. Once in test mode you will be able to test the functions of the CD mechanism. The manual also has the schematics and a full parts which will help to find the problem that will hopefully be shown by the test mode procedure. Hopefully a start.

Hi, It could be the power supply to the backlight LEDs or the connection to or in the LED strips. The monitor would have to be opened and further tested. If you decide to do this then if it is determined that the backlights are OK and the problem is with the mainboard it may be easier to replace the mainboard than to try and fix it without a schematic diagram. Search online for BN41-02352B to find suppliers. The mainboard board number was found by looking at the images in the ifixit guide below. If you decide to order a replacement board please verify the board number on your board as it may just be slightly different for whatever reason. Here’s the ifixit Samsung U28E510 Motherboard Replacement guide which will help to gain access to the board. Alternatively contact a reputable, professional electronics repair service and ask for a quote

HI @kteed What is the make and model number of the refrigerator? The defrost heater element is usually located directly under the evaporator unit which is located behind a panel inside the freezer compartment at the back of the compartment. Remove the panel inside the freezer compartment to expose the evaporator unit, evap fan and the defrost heater plus also a defrost thermostat and may be a temp sensor as well.

Hi @Paul Walsh Can you hear if the evaporator fan is operating? It is located in the freezer compartment behind a panel. If you open the door (either door) the fan should stop. When the door is closed the fan should start again. You may have to place your ear next to the fridge cabinet to hear it running and stopping etc. when the doors are shut then open. It will only run if the compressor motor is also running. You could also try manually operating the freezer door switch and listen or feel the air from the vent, inside at the back of the compartment, if the fan starts operating. The switch is not only for the light, it also signals the control board to turn off the evaporator fan because the door is open. By manually operating the switch you fool the control board into thinking the door is shut so it turns on the fan and the light goes out Do not confuse this fan with the condenser fan which is outside the compartments near the compressor. It can run whether the doors are open or not. If you can’t hear...

Hi @jamescartilla, You can’t add images etc to a comment on ifixit, only to questions and answers. (click on Options > Edit and then when the edit box opens click on the Insert an image icon - looks like an upside down envelope but I think it’s supposed to be a picture in a frame, on the right side of the box header bar) Are you sure that the 3 black, 2 white, 3 red wire cable is going to the lid? It looks like a power cable to me. The one next to it is most probably the video cable. Of more interest is the black cable coming out of the left hinge (I think), passing over the grey WiFi antenna cable. It doesn’t appear to be plugged in properly as the connector looks at a funny angle in the picture Here’s an image to show you where the cable is. (click on image to enlarge for better viewing)

The 3rd wire from a battery is usually connected to a thermistor attached to the battery which signals the temperature (resistance value changes with temp) to the battery management circuit in the motherboard.

Charging will be halted to if it got too hot before being fully charged, which may create problems e.g. a fire

If leaving the 3rd wire disconnected, the battery should not be left unsupervised whilst it is charging

The 3rd wire is usually connected to a thermistor attached to the battery which gives the battery management circuitry in the motherboard an indication of the temperature of the battery when it is being charged. The temperature (actually a resistance measurement that alters with the temperature) is used in conjunction with the voltage level, so that the battery is not being overcharged and getting too hot and creating potential problems if left charging unattended for long periods. The charging process is halted

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
