ОтветыSingle green horizontal line on laptop screen?Hi @hustlepremium , Try connecting an external monitor and check if it is there also. Most likely though it is a faulty display panel or a faulty LVDS cable or cable connection. Here’s a link to the service manual for the laptop. Scroll to p.78 to view the necessary pre-requisite steps and then the procedure to remove the display assembly. This should allow you to also inspect the cable connections. If you determine that it is a faulty panel, on p.77 you’ll find the part numbers for the panels available for the different variant models. (Usually the part number is printed on the back of the panel if you wish to verify which one you have). Search online using the part number only in the search box of your browser to get results for suppliers.

ОтветыAfter PC connected with USB, can't hear callerHi @Felke V, Try starting the phone in safe mode and check if it works OK or not. If it does then a downloaded app is the cause of the problem and it may just have been a coincidence that it occurred when you plugged it into a PC The trick is to find out which one is the culprit. You need to uninstall each download app, one by one, and test the phone in the “normal” mode to see if it works OK. When it does then the last app that was uninstalled was the cause of the problem. Start with the most recently installed or updated downloaded apps first. If it still doesn’t work in safe mode, try resetting the phone using the phone’s factory restore feature and see if this resolves the problem. Before performing the reset, backup the phone first, using the phone’s backup feature.. Be aware that a factory restore (or reset) will erase all your data and downloaded apps. It will restore the phone to its’ factory default (or last updated) condition. That is why it is important to backup the phone first. Once you have perf...

ОтветыHow to replace my thermal compound?Hi @kokohaishere , Here’s a link to the service manual for your laptop, taken from this webpage Scroll to p.49 to view the necessary pre-requisite steps and then the procedure to remove / replace the heat sink assembly. Once that is removed you can clean off and renew the thermal paste on the CPU/GPU etc. You can also clean the fan at the same time ;-)

ОтветыMy phone acts weirdHi , What is the model number of the phone? Try starting the phone in safe mode to see if it works normally. (Hopefully this safe mode procedure will work for your LG model. If it doesn't search online for LG (insert model number of phone) safe mode to find the correct procedure for your model phone. If it works OK when in safe mode, then a downloaded app is the cause of the problem. You need to uninstall your downloaded apps, one by one, and test the phone in "normal mode" between each uninstall to see if it works OK. When it does then the last app that was uninstalled was the culprit. If it still doesn’t work normally when in safe mode, try a factory reset to see if this resolves the problem. Before performing the reset, backup the phone using the phone’s backup feature ''Be aware that a factory reset will erase all your data and downloaded apps. it will restore the phone to its’ factory default condition. That’s why it’s important to backup the phone first.'' When you have completed the backup, factory res...

ОтветыDisplay says New CID: 30Hi @carmengauci, To see incoming phone call numbers displayed on the phone you need to have the Caller ID (CID) (also can be known as Calling Number Display -CND) facility enabled by your landline service provider. Depending on your provider this is usually a subscription feature on a landline service. If you haven’t previously requested the CID facility for your service and would like to have it, contact your landline service provider. If your phone shows “private number” on every incoming call then you haven’t got CID enabled. If your phone is connected to a VOIP service (phone over the internet connection) you may be able to enable the facility yourself by logging into the user interface of the modem and altering the phone settings as a lot of ISP provide the feature for free.

ОтветыFreezer is not circulating cold air?Hi @Rose Swift, You have not quoted a full model number, so I can't help more fully, but if you can hear a "whirring" sound in the freezer compartment but there is no air movement it may be that the evaporator fan blades have come adrift from the evaporator fan motor shaft, so that the motor turns (and whirs) but not the blade. Frost build up is normal as warmer air enters the freezer when the door is opened and the moisture in the warmer air ‘freezes” on the colder interior sides of the compartment. That is why most refrigerators these days have auto defrost . This occurs once every 8-12 hours (depending on maker). The compressor is stopped, the fans are stopped (you don’t want to blow cold air out unnecessarily when the doors are opened) and the evaporator defrost heater is turned on. The auto defrost lasts for about 20-30 minutes and then the compressor and fans start up again to drive temps back to the required settings. Is there a freezer door switch that you can manually operate simulating that the door...

ОтветыWhy is my pc not posting when ethernet cable is in?Hi @djholley , Flicking the power on and off quickly doesn’t help as it could send surges through the board corrupting data or settings. Go back to basics. Disconnect the HDD (either the HDD power cable or the data cable will do) and try clearing the RTC RAM (CMOS) which restores the BIOS to its’ default settings by removing/restoring the CLRTC jumper on the motherboard. Note: Do all of the above with the PC switched off and the power disconnected. Reconnect and switch on the power and check if it will now POST OK to a point where it says “no OS found” or similar error message. If removing the jumper does not resolve the problem you may have to remove the coin cell battery from the motherboard (note the way it is installed so that you replace it correctly) as well as the jumper to clear the CMOS back to default - see note above . Here’s a link to the motherboard manual. Scroll to Sect.1.2-1.3 to view its location and how to clear the CMOS. If it does POST OK now get into BIOS and disable the LAN controller, (...

ОтветыPhone doesn’ Blink to indicate unheard messageHi @nanbar , Has it worked OK before? If it has never worked and if you have a Uniden Dect 6.0 1760 phone, have you set up the Voicemail service with your landline phone service provider, you didn’t say? Go to their website to find out how to set it up. Be aware that with some providers it’s a subscription service. Here’s a link to the user manual for the above model phone. Scroll to p.13 to view how to set up the Voicemail access feature on the phone once you have set up the Voicemail service. If you have a different model Uniden Dect 6.0 phone what is its’ model number?

ОтветыIs it necessary to clean inside of my phone if it is fall into toilet?Hi @fixzahid , Water resistant doesn't necessarily mean waterproof. The specs state that it can withstand water up to 1 metre for 30 minutes, which is a bit different to 12 hours submerged! Whilst there are no problems for now that is not to say that they won't appear in the near future. Just so that you are aware of this Personally I would open it up to inspect it but I'm just cautious around electronics and water especially if the device is not new. Are there any minute cracks in the case or flaws in the seal due to normal activity over time which may have compromised its’ water resistant integrity for example? Here’s a link to the ifixit Samsung Galaxy S5 Mini Repair guide, if you decide to do this This link may also be of some help. Electronics Water Damage Hopefully you also cleaned the outside of the phone appropriately given where it was found submerged and also how the phone is used ;-)

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
