Repairing LED vs. CCFL displays

Technical Q&A with Elsin Electronic Solutions

DA: Are there differences in repairing LED displays vs. older CCFL displays?

Elsin Electronic Solutions: The only difference between LED and CCFL panels is the backlight, everything else is the same. Both LED and CCFL panels are equally difficult to repair. The disadvantage of CCFL panels with more lamps is when only one lamp goes off it is necessary to replace all of the lamps so the backlight is even. A CCFL panel can have only one lamp or tens of them. Sometimes, thanks to the prices of CCFL lamps, the backlight repair may be too expensive. The LED backlight has the advantage that it doesn't lose its luminosity, and thus it is possible to use a backlight unit from another panel (for example, an unrepairable panel).
