Common symptoms

Issues we regularly handle

Laptop & Computer Repair
  • Won't power on

    Try a different charger and wall socket, then unplug and hold the power button for about 15 seconds. If there is still no sign of life, bring it to the workshop.

  • Lines or dark screen

    Connect it to an external monitor or TV via HDMI. If the external display looks fine, the issue is likely the panel or the display cable.

  • Slow and overheating

    Use it on a hard, flat surface and keep the vents clear. If it shuts down from heat regularly, have it checked soon before other components are affected.

  • Not charging

    Check the charger cable for kinks or exposed wire and try another socket. Don't force a plug that feels loose in the port.

  • Liquid spill

    Shut it down immediately, unplug the charger and don't turn it on again even if it seems dry. Bring it in as soon as possible, as quick handling improves the odds.

  • Swollen battery

    Stop using it and don't charge it. Don't press on or remove the battery yourself, keep it away from flammable items and bring it to the workshop.

  • Completely dead

    Charge it for 30 minutes with a different charger and cable, then hold the power button longer. If it stays dead, bring it in with its charger.

  • Boot loop or random restarts

    If the phone still starts briefly, back up what you can. Avoid flashing it yourself, as it can wipe data or make things worse.

  • Water damage

    Turn the phone off, don't charge it and don't use a hair dryer on it. Bring it in quickly, as corrosion keeps spreading.

  • Swollen battery

    Stop using it and don't charge it. Don't press on the body or open the case yourself, and bring it in as soon as you can.

  • Not charging

    Try another cable and charger, and check whether the port is blocked by lint. Don't dig into the port with anything metal.

  • Sensor or signal issues

    Restart the phone and toggle airplane mode on and off. Note when the problem shows up so diagnosis is quicker.

Smartphone & Communication Device Repair
TV & Consumer Electronics Repair
  • No power

    Make sure the socket works by testing another appliance, and check the power cable. Don't open the TV casing, as parts inside carry high voltage.

  • Sound but no picture

    Shine a torch close to the screen. If you can faintly see the picture, the backlight is usually the culprit. Mention this when you contact us.

  • Lines on screen

    Take a photo or video of the lines and send it on WhatsApp. Avoid pressing or tapping the screen.

  • No sound

    Check the audio settings, mute and any connected devices such as a soundbar or set-top box.

  • Burning smell or sparks

    Switch off and unplug it immediately, and don't turn it on again. Bring it in or contact us for an inspection.

  • Turns on, then off

    Unplug it for a few minutes and try again. If it keeps happening, stop using it so the damage doesn't spread.

  • Won't switch on

    Test the socket with another appliance and make sure the home circuit breaker hasn't tripped. Don't take apart any electrical parts yourself.

  • Washer drum won't spin

    Check the drum isn't overloaded and the door or lid is fully closed. If it still won't move, stop and contact us.

  • Leaking water

    Cut the power first (switch off at the breaker if the socket is wet too) before wiping up any pooled water, then turn off the water tap. Don't use it until it has been checked.

  • Loud noise or shaking

    Make sure it stands level and nothing is caught inside. If the noise continues, stop using it.

  • Burning smell

    Switch off and unplug it right away, keep it away from anything flammable, then contact us.

  • Not heating or cooling

    Check the temperature and mode settings. If they are correct and it still doesn't work, note the symptoms for diagnosis.

Air Conditioner Service
  • Not cooling enough

    Clean the indoor unit's air filter as the manual describes and keep doors and windows closed. If it still won't cool, book an inspection.

  • Water dripping indoors

    Turn the AC off and move any electronics underneath it. It usually means a blocked drain line and the unit needs cleaning.

  • Unpleasant smell

    A musty smell usually comes from dirt and mould inside the unit. Book an AC cleaning.

  • Noisy operation

    Note whether the noise comes from the indoor or outdoor unit and tell us when you get in touch. Stop using it if the noise gets louder.

  • Won't turn on

    Replace the remote batteries and check the circuit breaker. Don't open the AC's electrical panel yourself.

  • Burning smell or breaker tripping

    Switch the AC off at the breaker and don't turn it back on until a technician has checked it.

    Check the power cable, UPS and socket. Note any beeps or indicator lights.

  • Projector dim or dead

    Let the projector cool down before restarting it and make sure its vents aren't blocked.

  • Monitor shows nothing

    Try another video cable and port, or connect it to a different computer to pin down the cause.

  • Frequent restarts or freezes

    Save your work and back up important data as soon as possible. Note when the problem tends to happen.

  • Burning smell from a device

    Switch the device off and unplug it immediately, and keep it out of use until it has been checked.
