Hi @jean101 , Have you tried adjusting the dash light dimmer switch to see if this makes any difference to the flickering effect, you didn’t say? (click on image to enlarge for better viewing)

Hi @Michael Kelly, If your laptop is a Lenovo Yoga 920-13IKB Type 80Y8 (check information label on the bottom of the laptop), then here’s a link to the parts Click on Select Commodity and then select the part type to find the part number of the part. Then search for suppliers by using the part number. Here’s the hardware maintenance manual that shows how to remove/replace the parts.

Hi @startropic1 , Getting a replacement touchscreen may not be easy as you would have to know what the original was first or at least the make and model number of the tablet. This is because they aren’t all the same, even though they may have the same dimensions. The wiring may be different and even if the same number of wires were used between the screen and the systemboard they may not use the same numbered wire for the same function. If there are no markings on the outside of the tablet then you may have to open the tablet and check for some on the inside. Check for any info on the touchscreen’s flex cable and if there is any then search for it. Alternatively you may be lucky and that the tablet supports OTG (on the go). If it does you can connect a USB mouse via a suitable OTG adapter (example only) and use it to navigate through the tablet to hopefully find out the model number information etc. Usually this is found in Settings > About. If you have an old USB cable and mouse you can make one yourself....

Hi, Try connecting an external monitor to the laptop and check if the problem occurs on it as well. If not it may be a loose or faulty video cable between the motherboard and the LCD panel or a faulty LCD panel. If it does, does it happen regardless of which GPU is being used? (I think that your model has an Intel and a Nvidia GPU, is this correct)?

Hi @davemeran , Check what the voltages are on the power board and go on from there. Having no images on the screen whether there are backlights or not means the mainboard but if the power board isn’t supplying the correct voltages then it won’t work properly anyway. There are several versions of your model using 2 different chassis so here’s a link to the service manual for the different models and chassis that that have. I’ve checked both chassis models and they seem to have the same pinout/voltages for the power board. Hopefully a start

Hi @notknown2giveup , Have you tried using the PVR control buttons to operate the recorder, you didn’t say? Looking at p.GB9 of the user manual, on the front of the recorder (behind a drop down panel?) there is a menu button and the arrow navigation buttons plus the OK button (see # 4 & 5) that should allow you to navigate through the different menus and select the appropriate function, setting etc Here’s the user manual [belge: UM-PVR9300T(UK)_400GB_09-0626.pdf] If this works this proves that the problem is related to just the IR reception section of the recorder (as you have replaced the remote) e.g a faulty IR receiver perhaps and not something more. An interim workaround but it maybe better than nothing as there’s not much information out there regarding service manuals, parts lists etc.

Hi, Here’s the hardware maintenance manual for the laptop. Go to p.50 to view all the necessary pre-requisite steps and then the procedure to remove the upper case assembly. Doing all this will give you access to the keyboard

Hi, Is the phone in a case at all? If it is try using it out of the case and see if you can be heard OK on a call If not or it still doesn’t work when not in a case try using the earphones with the microphone attachment plugged into the phone’s earphone socket when making or receiving a call to check if you can be heard OK. Alternatively use the phone in “loudspeaker mode” and check. If you can be heard OK when using either of these two methods then there is a problem with the phone’s internal microphone or perhaps the voice inlet hole on the bottom edge of the phone is blocked with lint or other debris. To eliminate a blocked voice inlet hole as a possibility, try using a vacuum cleaner to suck out any obstructions and see if this clears it. Do not use a pin or probe to try and clear it as you may damage the microphone which is behind the inlet hole. If it still doesn’t work after this then the phone will have to be opened and further tested to find the cause of the problem. It may be a faulty microphone...

Hi, There’s not much information out there on Toshibas but if the backlights aren’t working and there is no video either then more likely it is a mainboard problem. The tcon board only deals with the video signals between the mainboard and the screen.

Hi @criminalpartn , Did you let it start to boot into Windows before shutting it down i.e. Windows startup logo on screen? It needs to boot as it is Windows that starts the repair startup not the BIOS. BIOS gets it ready to boot i.e. manufacturer’s logo on screen until Windows logo when it is booting into the OS If still no good create a Win 10 recovery USB from any known working Win 10 PC. In the host PC go to Control panel > Recovery > create a recovery disc and follow the prompts. You will need an 8GB flashdrive and 40-60 minutes of time. When you have the USB, insert the USB in the laptop and start the laptop and get into BIOS and then enable Legacy USB (or CSM), save the changes, then restart the laptop. It should boot into the Windows Recovery menus off the USB. Go to Troubleshooting > Advanced and select the option you want.

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

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
