    It is problem of light engine that has dust layer on lcds, filters. Qualified local technican can clean it. dark halo affect is not caused by lamp/bulb.

    Thanks.

Mitshubishi TV WD65C8 picture is dark - has been that way since i bought it 2 yrs ago? sonenergy@qwest.net


If you have a dark picture I would first check lamp and see if correct, and if correct you could have a bad or weak ballast, but I would buy new mits lamp and replace and see if this helps if not check ballast

TV screen goes black, 43 lites appear and TV shuts off after 2 to 3 hrs of operation. It will restart OK however. 56" set is 4 yrs old, orig lamp in TV


If you have never replaced the lamp it is most likely to be the problem.Most lamps last 2-3 years under normal use.

Sheet of ice forms on bottom of freezer


Your defrost heater assembly has probably failed. Look at the ends of the heater for darkness like that of a bad neon bulb. Replace the heater assembly as a unit after removing the ice with a hair dryer. Becareful not to drop the glass heaters when replacing.

Screen going dark


Definitely. The lamp often looses oomph before it goes. Think about how long you have had your set. The average life seems to be around 2 years. Eventually your set will indicate the lamp needs replacing, if it hasn't already. I see your posting is about 6 months ago. Are you willing to verify for everyone else?
