Hello,

This type of failure is usually the backlight inverter power supply. We have an article posted on our site at: http://www.ccl-la.com/blog/index.php/capacitors/ that explains what normally goes out and what needs to be replaced to do the repair. If you would like to post a few pictures of the boards in your unit to our forum section at: http://www.ccl-la.com/forum/index.php then our techs will contact you and guide you thru repairing the unit. If you don't want to do the repair yourself we do offer a repair service, that info can be found here: http://www.ccl-la.com/blog/index.php/service-request-form/

I hope this helps, if so please rate our solution.

What is the model number? Did you open it up and inspect the caps in the power supply, see pictures here: http://s807.photobucket.com/home/budm/allalbums
\015\012Any parts can fail and can give the same problem for not getting backlights to work, so there is no way to say which Diode, resistors, transistors, transformers, fuses, lamps. Please open it up and tell us what you see inside first, that is a start so we can guide you further, sometime it will be more practical to replace the PCB assembly than trying to repair surface mounted unless you have proper tools to do so.

It is very scratchy and distracting and has ruined the resolution on the screen. Can someone tell me what it is and if it is fixable?
