Hi @wattdee , What is the model number of your WeMo? If it is a F7C027 can you hear a "click" coming from the switch when you try to turn it on? If so this is the relay in the switch connecting the power to the outlet. If there is a click and there is no power then the relay contacts may have burnt out and the relay will have to be replaced. If there is no click then either the relay coil is faulty or it is not being operated when required. The switch would have to be opened and the problem further diagnosed Here’s a link to the ifixit Belkin WeMo Switch Teardown guide which may be of some help. As this device switches potentially lethal voltages, if you don’t know what you’re doing when testing electronics where these voltages are present then DON’T. Leave it to the experts. Update (06/23/2019): Hi @wattdee , At least hearing the relay operate indicates that the signalling system from the controller to the switch is working. Most of the components in the switch are there to get the relay to operate and...

Hi @asteri It seems as though the LCD screen backlight fuse on the motherboard has failed. I cannot find a video which shows the location of the backlight fuse on a PSP 3001 motherboard but have read that it is in a different spot than on a PSP 3000. You may have better luck in finding a video that shows how to replace the backlight fuse on a PSP 3001 ;-) Here’s a link to the ifixit PSP 300x Motherboard Replacement guide. This should be of some help in gaining access to the motherboard so that you can find the fuse. The component should be designated on the board with an F (F for fuse). According to this link there are 6 fuses on the motherboard for a PSP 3xxx. By using an Ohmmeter you should be able to check all the fuses for continuity and the one that fails most probably is the backlight fuse. If you do find it, then you’ll need SMD soldering tools and skills, (and the appropriate new fuse) to effect the repair. Hopefully this is a start and of some help.

Hi, I cannot find a circuit for a Yamaha P-45 but have found the service manual for a Yamaha P45-B which hopefully will be close enough to be of some help. To download the file click on the “I am not a robot” checkbox and then select download. Be patient it takes a little while to find the file. I don’t know about notes in music but looking at the circuit it appears that a +3.3V supply is fed to each note in the scale and when a key is pressed this voltage changes and the change is detected by the CPU and the appropriate note is played. Since only the first 4 lower D notes don’t work it may be that there is a break in the wiring multiple or a loose connector to the section of the keyboard. Check that the harness plugs between the DM board Connector 201 and the GHL88M board Connector 2 and the GHL88M board Connector 1 and the GHL88L board Connector 1 are securely connected and that there is +3.3V appearing on the appropriate pins as shown below The GHL88L, M and H boards may be directly below the keys Here...

Hi @christopher90 , Have you checked that the Handlers setting in Chrome is enabled? Go to Chrome menu (3 vertical dots right side of page) > Settings > scroll down to Advanced > Privacy and Security > Site Settings > Handlers > enable

Hi, Here’s a link to the service manual taken from this webpage. Scroll to p.21 to view the necessary pre-requisite steps and then the procedure to remove the heatsink. This should show you whether the GPU is removable or not. Also not sure regarding the CPU as it is not mentioned as a removable component in the manual.

Hi, If it is still covered by the manufacturer’s warranty, I suggest that you get it repaired by them. If it is no longer under warranty, here’s a link to the ifixit Thermomix TM5 Repair guide which may be of some help in opening the device to ascertain what the problem may be. This link may also be of interest. It seems that you are not alone in having problems with the scales in this device.

Hi, Can you take a picture and download it to a computer to check if the image is OK? I realize that you cannot "see" what you are taking. If the downloaded image is just a black image then there may be a problem with the CCD sensor or sensor connection to the motherboard. If the downloaded image is OK then there is a problem transferring the image from the sensor to the camera's LCD screen. Here's a link to a video that shows how to dis-assemble the camera. I know it's not for your particular fault but it still may be of some help in gaining access to the components of the camera.

Hi @maki74 , The charge light turns off when the battery is fully charged so at least it proves that something is working. If you haven’t already done so, try the reset procedure - scroll down to ''reset from startup'' section and see if that works in turning on the tablet. I think that the manual means the Power button and the Volume Down button ( shown as Vol - ) should be held operated together If that still doesn’t work, how old is the tablet? There is a 12 month limited manufacturer’s warranty on the device. If the warranty period is still valid follow the directions (p.75 of the manual) as to what to do to obtain warranty service. If the tablet is out of warranty it will have to be opened and the problem further diagnosed. For example it may be something as simple as a faulty power button or perhaps it could be reset by disconnecting the battery and discharging the systemboard (by holding the power button operated for about 30 seconds to drain any residual power in the system) and then reconnecting...

Hi, Try a hard reset and see if this resolves the problem. Here’s a link to the user manual. Scroll to p.3 (p.12/41 in the .pdf file) to view how to perform a hard reset.

Hi, Is the laptop still covered by the manufacturer’s warranty? If so contact the manufacturer regarding the problem. Research online indicates that you are not alone in having problems with the power button. Some have had the problem resolved under warranty by the manufacturer replacing the power button board (with a refurbished button!) whilst others, where the warranty has lapsed, have replaced the button board themselves and hoped that the new button lasts. Here’s a link to the service manual for the laptop, taken from this webpage. Scroll down to sections 22-23 to view the necessary pre-requisite steps and then the procedure to remove/replace the power button board.

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
