Poynt GoDaddy Terminal: LCD Cold Damage Analysis - Solar... | terminalfaults.org

Technical Background:

Liquid Crystal Displays (LCDs) rely on the alignment of liquid crystal molecules to modulate light. Low temperatures increase the viscosity of these liquid crystals, hindering their ability to respond quickly to changes in voltage. The optimal operating temperature for LCDs typically ranges from 0°C to 50°C. Outside this range, performance degradation or permanent damage can occur. The Poynt GoDaddy Terminal likely uses a TFT (Thin Film Transistor) LCD, which is susceptible to cold-related issues.

Symptoms:

Observed LCD malfunction or damage reported after exposure to low temperatures. Symptoms may include slow refresh rate, reduced contrast, image retention ('ghosting'), or complete display failure.

Possible Causes:

Exposure to temperatures below the terminal's specified operating range.
Prolonged storage in cold environments prior to activation.
Rapid temperature changes causing thermal stress on the LCD panel.
Condensation forming inside the device due to temperature fluctuations.
Degradation of the LCD's backlight due to low temperature affecting the phosphor efficiency.
Battery drain in cold weather, impacting the LCD's operating voltage.

Solution:

1

Allow the terminal to gradually warm up to room temperature (20°C - 25°C) before use. Do NOT use a direct heat source.
2

Check the terminal's battery level. Low battery voltage can exacerbate LCD performance issues in cold conditions. Charge fully with the provided power adapter.
3

Power cycle the device (turn off, wait 30 seconds, turn on). This may reset the display controller.
4

Inspect the LCD screen for any visible damage (cracks, discoloration). Report any physical damage immediately.
5

Ensure the terminal's firmware is up to date. Software updates can sometimes improve display performance.
6

If possible, test the terminal indoors at a stable temperature before deploying it in the field.
7

If the LCD issue persists after warm-up and power cycling, contact Poynt support or an authorized repair centre.

Safety Warning:

Low temperatures can reduce battery life and potentially cause premature battery failure. Avoid charging the terminal in extremely cold environments. Safe Handling: Unplug the terminal from any power source before cleaning. Use a dry, lint-free cloth. Do not use liquids. Avoid dropping or impacting the device, especially when cold, as materials become more brittle.

Prevention:

Store the terminal within its specified operating temperature range (consult the manufacturer's documentation).,Use an insulated carrying case when transporting the terminal in cold weather.,Avoid exposing the terminal to rapid temperature changes.,Allow the terminal to acclimatize to room temperature before powering it on after cold storage or transport.,Ensure the terminal is powered off completely when not in use to minimize battery drain in cold environments.,Regularly clean the LCD screen with a soft, dry cloth to remove any condensation or residue.

Expert Tip:

Try adjusting the screen brightness. In some cases, reducing the brightness slightly can improve LCD performance in cold conditions by lowering the voltage demand. A full discharge/recharge of the battery may recalibrate the power management system; observe voltage readings before and after. Check if a recent software or firmware update caused the LCD issue; rollback if necessary (if possible through user interface).

Frequently Asked Questions

•What are the terminal's operating and storage temperature specifications?

Consult the Poynt GoDaddy Terminal's documentation or the manufacturer's website for detailed temperature specifications.

•Can using a screen protector help prevent LCD damage in cold weather?

A screen protector will primarily protect against scratches and minor impacts but offers minimal insulation against temperature extremes. It will not prevent cold-related LCD issues.

•What is the warranty coverage for LCD damage caused by cold exposure?

Warranty coverage varies. Contact Poynt support to determine if cold-related LCD damage is covered under your specific warranty terms.
