6. Panel and Screen Defects
It is vital to know the difference between a repairable board fault and a broken screen.
- Horizontal/Vertical Lines: If pressing the screen changes the lines, it is a loose connection (TAB bond). If lines are solid and permanent, the panel's internal contacts are broken. This is usually not economical to repair.
- Pressure Marks: White spots in the middle of the screen are usually caused by loose screws or debris behind the diffuser sheets inside the panel assembly.
2. Backlight vs. Panel Issues
A common point of confusion is a TV that has sound but no picture.
- The Flashlight Test: Shine a flashlight on the screen in a dark room. If you can see a faint image, the panel is working, but the backlights are dead.
- The Repair: This requires replacing the LED strips inside the panel. The "V7.0" guides often provide the LED strip models and voltages required.
2. Symptom-Based Repair Flowchart
3. Vertical or Horizontal Lines on Screen
- Symptom: Colored lines, repeating patterns, or mirroring.
- Diagnosis: First, flex the TV frame slightly. If lines change, the tab bond or panel driver IC is failing. If lines are static, it’s the T-Con board or mainboard.
- Fix:
- For V7 0 LCD: Carefully isolate the side tabs with tape (the "tape trick").
- For V7 0 OLED: Reseat the ribbon cables on the T-Con. Clean contacts with 99% IPA.
- See the PDF’s troubleshooting flowchart on pages 8-9.
