I'm preparing to replace the built-in monitor's lcd panel on a Dell Inspiron E1505. It appears the failure is likely the backlight, rather than the inverter, but there are a couple symptoms that it's exhibited that I did not find much about when researching:
From what I understand, pink - flickering - dim, etc. indicate a failing backlight, while hissing sound typically is the inverter.
When it first started, it flickered pink for a few minutes, light went completely dark - with picture still on screen. That would sound like the backlight.
Here are the two interesting things:
-- Whenever it would flicker, it would also hiss. Can a flickering backlight *cause* the inverter to hiss?
-- If the computer is completely powered off for at least several months, then sometimes the LCD will display for a few hours (still dim pink). After a while it will go back to a momentary flash, if at all, when first starting/ waking computer. (Then no light, but picture can be seen with flashlight.)
Do those symptoms also seem normal for a failing backlight? And that it's likely not just the inverter?
