The defective NEC 121PW181 (TDK, CXA-0359) CCFL Backlight inverter will cause the following symptoms:
No images on LCD screen, but by using a flash light to shine on the surface of LCD screen, all contents are still visible. Image comes on in fraction of seconds and it disappear.
In most cases, replacing defective 121PW181 may not solve the problem, because the defective 121PW181 is cause by bad CCFL lamps. So, when replacing 121PW181 inverter, you also need to replace two CCFL lamps, too.
However, the most cost effective solution will be upgrading 12.1 inch NEC LCD to our LED Backlight kit. To extend NEC LCD Screen’s life and improving its performance, upgrading to UB54 Series LED backlight kit seems to be the best option. It is easy to install, no technical skill require, no soldering require, anyone can do it!
LED has a longer lifespan, typically lasting over 100,000 hours (last 10X longer than CCFL).
This LED upgrade kit included the following items:
1 LED strip (Replacing CCFL Lamp)
1 LED driver (Replacing Defective 121PW181)
1 wire adapter (Connect 121PW181's wire harness directly into our LED driver)
