Power button lights up but the display is deadDears, I have a Lenovo ThinkPad T460 (board is BT462 NM-A581 Rev:3). Whilst the laptop was powered on (plain web browsing,...
Antwort auf „Camera flap does not close properly”Hi From the picture it looks like the front of the lens is damaged (lower right corner). It looks like there is a dent there. If this is the case, the flaps might be physically blocked from operating.
Antwort auf „Disable storage function of USB ports.”If you are running Windows and have an AD domain, then you can do it via policy (see below) This is not specific for USB drives. It applies to SD cards as well as CD-drives and many more. You have many options to choose from.
Antwort auf „Not connecting directly do router through wan port”Hi Checks 2 things please (user manual here: https://www.downloads.netgear.com/files/...) (1) ethernet data offloading should be disabled (page 33) (2) usb tethering should be disabled (page 40) —> usb should be set to charge only. If the data offloading is enabled (especially via the ethernet connection), then the ethernet port on the MR1100 effectively works like a LAN port. It is still strange that the Airport get an IP address if a switch is connected in between. Cheers! Bogdan
Antwort auf „MFC-J430Wabsorber full No Purge plz need video How 2 change absorber”Hi Please check the service manual here : https://www.manualslib.com/products/Brot...-Mfc-J430w-2972590.html At page 234 the ink absorber box is listed with all its parts. However, before you go ahead and disassemble the unit, make sure you have a new absorber box ready or at least new felt to replace the old one. You can get them cheaply on Chinese websites. I did this for an Epson printer and there is no practical way to actually clean the old felt. It really needs to be discarded. Also, make sure you wear gloves and work on a surface which you don’t mind staining and have plenty of paper towels available at hand because once you remove the tubes, ink will leak. Ink on your hands will go away in 1-2 days. On your clothes in 1-2 minutes but only with a pair of scissors :) Cheers! Bogdan
Antwort auf „No power, no led, no POST. Replaced Motherboard, same issue.”Hi Had the same woes with a Lenovo T460. Charging light was on, power button would light up when pressed, but still nothing was displayed and no error beeps. In the end it turned out to be a faulty memory module. Once I’ve replaced the memory module, the laptop came back to life. So, it’s worth checking this too. Cheers! Bogdan
Antwort auf „Water Damaged Note 3”Hi Before giving up, try to measure the voltage on the battery terminals. A working battery should have at least 3.8V. If the outpus is close to 0v, then the battery is dead. The phone will not start with a dead battery, even if the charger is plugged in. Has the same problem with a Nokia phone. The phone got dunked. Lithium batteries have internal circuitry to protect against short-circuit. Once the fuse on the battery management module blows, it’s game over for the battery. Good luck! Bogdan
Antwort auf „How do I clear or brighten the optical viewfinder?”Hi There is a difference in how a dSLR camera meters. In live-view, the actual camera sensor is used for metering, while outside the live-view, a separate metering sensor is used. Please see attached image. The location of the components might be different for your camera, but the exact same principle applies. When not in live live, light enters the lens and hits the main mirror. From there, some of it passes though (the mirror is not completely opaque) and hits a secondary mirror and then the phase detect autofocus sensor. What gets reflected by the main mirror hits the pentaprism which in turn directs it to the optical view finder and the metering sensor. Below the pentaprism there is a tiny display. This is used to provide the info you see in the viewfinder. The light needs to pass though this transmissive display too. This is the reason why the viewfinder is dark when there is no battery in the camera body (even if the camera is turned off, power is still delivered to this tiny display). If this...
Antwort auf „error message says E6”Hi According to Canon, Error 06 indicates a fault of the sensor cleaning module. To work around this: (1) turn camera off (2) remove the battery (3) turn camera on (without battery) (4) wait 5-10 minutes (5) turn camera off (6) insert battery (7) turn camera on If the camera starts ok, disable the automatic sensor cleaning from the menu. This a work-around to be able to use the camera. But, in the long term, you need to have the camera serviced. Sadly the cleaning module is integrated into the sensor (low pass filter) and I’m not sure if it can be replaced separately. Considering the camera is quite old already, the repair cost might not be justified. Cheers! Bogdan
Antwort auf „Power adapter cable isolation damnaged”Hi Generally it’s the outer sleeve of the cable that fails. If the internal wires are ok (jackets are not damaged), the best way to fix it is to use a drop of hot glue and then shrink tube. It’s a far more permanent (and elegant) solution than electrical tape. The hot glue helps to make sure that the internal wires remain put and the shrink tube provides better insulation that electrical tape because once in place, it remains there forever. The electric tape in this context has a tendency to unravel. If the sleeves of the internal wires are damaged, then stop using it. It can cause a short-circuit and damage either the power adapter, the logic board or both. Sometimes fuses can be replaced, but it’s a costly process which far exceeds the cost of a new adapter. Cheers! Bogdan
Antwort auf „Computer would not restart after RAM upgrade”Hi It’s possible, but unlikely for the logic board to be damaged. Logic boards and memory modules are electrostatic sensitive devices. Touching them can potentially create small electrostatic discharges that would damage them. Most likely: (1) the new memory modules are not compatible or faulty. usually the system will beep when you try to power it on and there is a memory issue. But not always. I myself have a laptop which had a faulty memory module and simply refused to turn on. No beep, no nothing. Replaced the module and all was fine. (2) some of the connectors are not properly seated. Because the entire logic board needs to be removed in order to access the RAM slots, there are multiple connectors which need to be disconnected and then connected back. I would try the following: (1) open the iMac again and carefully check that all connectors are plugged back correctly. (2) if this does not work, put in the old memory modules and check Good luck!
