Lexmark C534dn has a blank display and a red light. How do I get the display back and a green ready light?


If display is blank you likely have a bad display or some other problem that will require replacements parts. Keep in mind that on Lexmarks the control panels are keyed to the formatter so you cannot just get a used panel from another printer, you must purchase a new one.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Turn tv on. green light solid display, no picture or sound


The flashing green light is likely indicative of a self-test failure, indicating the TV has detected some sort of internal fault. With no picture or sound, one strong suspect is the power supply. Flat-panel TV's have an internal DC power supply that converts the inbound AC current, and when these fail, or are unable to supply a minimum level of power to the set, it can behave as you describe, providing only enough power for the green light to illuminate.

My KDS-55A2000 displays some shades of blue as green. It's not just one area of the screen but the entire screen. Flesh tones can be adjusted to look pretty normal but scenes with light blue sky look...


Your t con board is responsible for the image on your screen. Your colors are all there but they are f---ed up in certain scenarios.

That is the only board on your set that be causing this anomaly.
