Detailed Repair Guide: Sony TV Screen Problems
1. Lines on Sony TV Screen
What Causes Lines on a Sony TV Screen?
Lines on a Sony TV — whether horizontal, vertical, or multicolored — are one of the most common display issues. They are typically caused by:
- Loose or damaged ribbon cables connecting the T-CON board to the LCD panel
- Failed T-CON (Timing Controller) board — the component responsible for driving the image to the panel
- Physical damage to the LCD panel — especially after impact
- Driver IC failure — small chips along the panel edge that control rows and columns of pixels
How to Diagnose Lines on a Sony TV
- Power cycle the TV — turn it off for 60 seconds and back on. If lines disappear and return, it’s likely a loose connection.
- Check if lines are consistent — lines that move or change suggest a T-CON issue; fixed lines suggest panel damage.
- Apply gentle pressure to the back panel — if lines temporarily disappear, a ribbon cable is loose.
- Connect an external device — if lines are absent on an external source, the issue may be software/firmware related.
Sony TV Lines Repair Steps
- Safely discharge and open the TV — unplug for at least 5 minutes before opening the back panel.
- Inspect and reseat ribbon cables — carefully disconnect and reconnect the flat ribbon cables between the T-CON board and the panel.
- Replace the T-CON board — if reseating doesn’t resolve the issue, a T-CON replacement is the next step.
- Replace the LCD panel — if damage is physical, the panel itself needs replacement.
⚠️ Warning: Opening your Sony TV yourself may void any existing warranty. For safe, professional repair, contact Refitec — your trusted Sony TV service center near Nairobi. 📞 0704843613
2. Sony TV Screen Flickering
What Causes Sony TV Screen Flickering?
Screen flickering on a Sony TV can be intermittent or constant and is caused by:
- Faulty or aging backlight LEDs — the most common cause in Sony Bravia TVs
- Loose HDMI or power cables
- Software/firmware glitches
- Failing power supply board — causing inconsistent voltage to the backlight
- Defective main board
How to Diagnose Sony TV Flickering
- Try a different HDMI cable and port — rule out connection issues.
- Test with a different input source — if flickering stops, the issue is with the original device.
- Update Sony TV firmware — go to Settings → Support → Software Update.
- Check power supply — flickering that worsens with brightness is a backlight/power board issue.
- Perform a factory reset — Settings → Device Preferences → Reset.
Sony TV Flickering Repair Steps
- Replace backlight LED strips — when LEDs age unevenly, they cause flickering; a full backlight strip replacement restores stable brightness.
- Replace the power supply board — if voltage output is unstable, the power board is the culprit.
- Inspect and replace the main board — if all other components test fine, the main board may need replacement.
💡 Pro Tip from Refitec: Flickering that gets worse after the TV warms up almost always indicates failing LED backlights — a common Sony Bravia repair that Refitec completes quickly and affordably. 📞 Call/WhatsApp: 0704843613
3. Sony TV Black Screen
What Causes a Sony TV Black Screen?
A black screen is one of the most alarming Sony TV problems but is usually repairable. Common causes include:
- Failed backlight — screen appears black but you can faintly see the image with a flashlight
- Faulty power supply board — TV won’t power on properly
- Defective main board — no signal output to the screen
- Damaged LCD panel — especially after a power surge or physical impact
- Bad T-CON board — panel receives no signal
How to Diagnose a Sony TV Black Screen
- Check the power LED — if it blinks or glows, the TV is receiving power; the display chain has failed.
- Shine a flashlight at the screen — if you can faintly see an image, the backlight has failed (not the panel).
- Listen for sound — if audio plays but no picture, the issue is in the display chain (backlight, T-CON, or panel).
- Test with a different HDMI source — rules out input signal problems.
- Attempt a soft reset — hold the power button on the TV (not remote) for 10 seconds.
Sony TV Black Screen Repair Steps
If you see a faint image (backlight failure):
- Open the TV back panel and access the LED backlight strips.
- Use a multimeter to test LED strip continuity.
- Replace faulty backlight LED strips — Refitec stocks strips for all Sony Bravia models.
If there is no image and no sound (main/power board failure):
- Test the power supply board capacitors — swollen capacitors are a telltale sign of failure.
- Replace the power supply board or main board as needed.
- If the panel is physically cracked or damaged, a panel replacement is required.
