The Canon EOS 70D is a versatile DSLR camera with a fully articulating 3.0-inch LCD touchscreen, ideal for live-view shooting, video recording, and menu navigation. However, users sometimes encounter issues where the LCD screen remains dark or unresponsive. This guide covers step-by-step methods to activate the LCD screen, troubleshoot common issues, optimize settings for different shooting scenarios, and maintain the display for long-term use.
Ensure the camera is powered on by sliding the power switch to the <ON> position. Verify the Mode Dial is set to a valid shooting mode (e.g., A+, P, Tv, Av, or M). In some cases, switching to Movie Mode (the video camera icon) will force the LCD to activate[^16][^28].
Note: In Scene Intelligent Auto (A+) mode, the LCD may default to minimal display to conserve battery. Press the INFO button to cycle through overlay options[^11].
The INFO button cycles through display modes (e.g., minimal overlay, histogram, electronic level). If the screen is off, press it repeatedly until the desired overlay appears. For touchscreen models, the DISP button may toggle the screen on/off[^5][^11].
- Flip the Live View/Movie switch (located near the viewfinder) to the camera icon.
- Press the Start/Stop button (red dot) to activate the LCD for live preview[^24][^15].
Pro Tip: In Live View, use the touchscreen to adjust focus points or swipe through settings like ISO and aperture[^10][^14].
The Canon 70D has a proximity sensor near the viewfinder that deactivates the LCD when your eye approaches. If the sensor is blocked (e.g., by dirt or a misplaced finger), the screen will stay off. Clean the sensor area with a microfiber cloth or adjust the eyecup[^5][^20].
Navigate to Menu > Second Tab (Orange) > LCD Brightness and use the slider to increase brightness. For outdoor shooting, set it to 7 (maximum)[^1][^9].
Warning: High brightness drains battery faster. Revert to 3–4 for indoor use.
A misconfigured custom setting may disable the LCD. Perform a factory reset via Menu > Third Tab (Yellow) > Reset All Camera Settings[^11][^47].
- Portable Display Test: Use Magic Lantern's bootloader routine to check if the LCD hardware is functional[^34].
- Check Connections: If the screen flickers or shows discoloration, the ribbon cable connecting the LCD to the motherboard may be damaged. Replacement costs $50–$120[^35].
The LCD is essential for video recording and live-view shooting. Enable it by:
- Switching to Movie Mode.
- Adjusting focus manually or using Dual Pixel CMOS AF for smooth transitions[^10][^29].
Touch AF in Video:
1. Set AF Method to FlexiZone-Single.
2. Tap the screen during recording to shift focus between subjects[^4][^29].
The capacitive touchscreen supports:
- Tap-to-Focus: Frame your shot and tap the subject for instant focus[^10].
- Quick Menu Adjustments: Swipe left/right to access ISO, white balance, and exposure compensation[^3][^14].
Rotate the LCD 180° for vlogging or 90° for overhead shots. Use Grid Lines (enable via Menu > Shooting Tab > Grid Display) to align compositions[^22][^44].
Issue | Solution |
---|---|
LCD remains black after startup | Press INFO repeatedly or reset settings43. |
Screen turns off during shooting | Disable Auto Power Off in Menu > Third Tab > Auto Power Off. |
Touchscreen unresponsive | Clean the screen or recalibrate via Menu > Second Tab > Touch Control8. |
Flickering or discoloration | Replace the LCD ribbon cable or screen1419. |
Error 70/80 | Likely a mainboard failure. Contact Canon support for inspection20. |
Apply a tempered glass screen protector to prevent scratches. Canon's LCD coating resists smudges but is vulnerable to sharp objects[^16][^21].
A failing battery may cause LCD flickering. Use genuine Canon LP-E6 batteries and avoid third-party alternatives[^18][^38].
- Avoid exposing the camera to humidity or sudden temperature changes, which can fog the screen[^13].
- In cold weather, keep the camera under your coat to maintain optimal LCD responsiveness.
Enable the built-in level via Menu > Shooting Tab > Electronic Level to prevent tilted horizons[^20].
Use Quick Control Screen (press Q button) to rearrange frequently used settings like ISO and metering mode[^9][^46].
In Live View, activate Exposure Simulation (Menu > Live View Tab) to preview brightness and depth of field[^9][^46].
The Canon 70D's LCD screen is a critical tool for composing shots, reviewing images, and navigating menus. By following these steps, users can resolve most display-related issues and leverage the touchscreen's full potential. For persistent hardware problems, consult Canon's support or a certified repair technician. Regular maintenance and smart settings adjustments ensure the LCD remains a reliable asset for years.
The proximity sensor near the viewfinder may be blocked. Clean the area or adjust the eyecup[^5][^20].
No. The LCD automatically deactivates when the camera detects your eye near the viewfinder[^3][^9].
Set AF Method to FlexiZone-Single and tap the screen during live view[^10][^29].
Increase brightness via Menu > LCD Brightness or use the viewfinder[^1][^9].
Yes, but it requires disassembling the hinge and reconnecting the ribbon cable. Follow iFixit's guide[^2][^35].
