Hi, Just verifying that pictures taken using the camera and then downloaded and viewed on a computer are OK i.e. no lines on image? Not sure if you meant this when you said "everythings else seems to be ok." If they are OK, maybe double check the connections from the LCD display to the control board behind the screen and also the cable connection to the control board from the camera. Also that the flex cable ends are clean etc. Try not to handle the part that goes into the connector socket with your fingers. Here's a video that may help.

Hi @yarddog Search online for Vankyo S30 parts to get results for suppliers (example only) that suit you best.

Hi, From your description it is not passing POST (Power On Self Test) or even trying to start POSTing. To eliminate the possibility that it is a corrupted BIOS that is preventing a normal start try a power refresh and see if that resolves the problem Disconnect the charger if connected and then open the laptop and disconnect the main battery from the motherboard (you don't have to remove it, just disconnect it). Next remove the RTC coin cell battery from the motherboard and then press and hold the Power On button for a full 30 seconds and then release it. With the RTC battery out, measure its voltage. if it is <2.5V DC replace it. It is a RC2032 coin cell battery, available most everywhere e.g. supermarkets. Reinsert the RTC battery (+ve on top), reconnect the battery, connect the charger and try turning the laptop on. Not that you need it but here's the maintenance and service guide for the laptop. See p.34 and p.55 to see how to disconnect the battery and remove the RTC battery. If still no good, what is...

Hi, Here' s the section from the service manual for the receiver, that shows the procedure to string the dial cord.

Hi, (1) Is the phone in a protective case at all? If so remove it from the case and check if you can be heard OK when using the phone on a call. The case may be blocking the microphone's voice inlet hole found on the bottom edge of the phone. (1) Try using headphones with a microphone attachment plugged into the headphone socket of the phone when making a call and check if you can be heard OK. Alternatively try using the phone in loudspeaker mode (aka hands free mode) and check. If you still can't be heard then there is a problem with the voice transmission circuitry in the phone. The phone would have to be opened and the problem further diagnosed as to what is causing it. If you can be heard OK then there is a problem with the phone's internal microphone or perhaps the single voice inlet hole on the bottom edge of the phone may be blocked with dust or lint etc. Do not use a pin or probe to try and clear the hole, as you may damage the microphone which is behind the hole. Try clearing the hole by using a...

Hi @malikpuspa 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. The corrosion starts immediately and is ongoing until it is completely cleaned away First do not try to charge or to turn on your phone and then 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 and clean all the affected parts using Isopropyl Alcohol 99%+ (available at electronics parts stores) to remove all traces of corrosion and water. If possible do not use "rubbing alcohol" as in some cases this is only 70% IPA or less, can contain additives and is not as effective. If you do have to use it check the label to verify the amount of IPA. The higher the percentage of IPA the better Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted pcb be gentle when handling and...

Hi @pwansley Not sure if this is the same keyboard but here's a video that shows where the two CR2032 coin cell batteries that power the keyboard are located. Worth checking anyway.

Hi @don2020 , CL indicates that the child lock function has been enabled. Here's an image from the user manual that shows how to enable/disable the feature. (click on image to enlarge)

@Itay Levy What is the model number of the motherboard? Look for a coin cell sized battery on the motherboard. Remove it from the motherboard and measure its voltage. If it is <2.5VDC replace it. Usually it needs to be gently prised out of the battery holder. The battery type number should be marked on the battery. Usually it is a CR2032 available most everywhere e.g. supermarkets. Do this with the power disconnected from the computer. Before reinserting (or replacing) the coin cell battery (usually +ve on top marked on the battery), press and hold the computer's Power On button for a full 30 seconds and then release. This will reset the BIOS if it has been corrupted for some reason, preventing a normal start. Reinsert the coin cell battery, reconnect the power to the computer and try turning it on. If it turns on there may be a message saying the date and time is incorrect. This is normal as the BIOS has been reset to factory default settings. Once the date and time has been corrected, the message won't...

@Rick C Try using the phone in safe mode and check if it is any better. It may be that there are apps downloading data in the background, unbeknownst to you and this is slowing things down. Alternatively go to Settings > Connections → Data usage → Data saver and enable it and check performance. Basically the two options above do the same thing i.e. prevent data usage by apps without you knowing about it and also it helps to work out if it is a downloaded app or not that may be causing the problem The difference is that with safe mode, downloaded apps i.e. apps that you downloaded and installed and not ones that were already installed will not be loaded on startup so that they can download in the background. Not all downloaded apps do this of course. Depends on how they're designed to function by the developer of the app. With data saver it means that the apps are still able to be used but you will get a message about going "online" (or similar) as they won't work until you do. All you have to do is to...

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
