Describe the Picture Problem Precisely
Useful clues include solarized or negative-looking colors, washed-out video, a purple or green cast, duplicated images, posterization, half-screen distortion, horizontal bands, or vertical lines. Photograph the symptom because the exact appearance often matters.
Use the TV Menu to Separate Source Problems
Open the television's built-in settings menu. If the menu looks normal while one HDMI source is distorted, test another cable and source before opening the TV. If the menu is distorted too, the problem is more likely within the display or video-processing path.
T-Con and Ribbon Connections
On many LCD televisions, the T-Con controls timing and data sent to the panel. T-Con faults can create severe color errors, double images, half-screen problems, or washed-out video. With power disconnected, inspect accessible ribbon connections for obvious poor seating or damage.
Main Board Possibilities
The main board processes incoming video before it reaches the display circuitry. If multiple inputs and the TV's internal apps produce the same abnormal video, the main board remains one possible cause—especially when other smart-TV or input functions are also behaving incorrectly.
Panel Failure Can Mimic a Bad Board
Panel driver circuitry and bonded connections can create symptoms that closely resemble T-Con faults. A fixed line or area that never changes on any source can be a panel clue. Replacing boards will not repair a physically cracked display or failed bonded panel connection.

Do Not Use Appearance Alone to Match Boards
Even if diagnosis points toward the T-Con or main board, visually similar boards can have different firmware or panel compatibility. Identify the exact assembly/service number on the original component.
