Start by replacing the two STK392-110 IC's on the power board and also check all the resistors aroung them to make sure they have not changed value.

Although this is a simple repair and requires replacing the two convergence IC's generally STKs it should not be attempted by an unqualified or inexperienced person. Laughing

Also, This is a common problem with Toshiba Rear proj tvs but also Samsung and a few others. Let the Buyer Beware. Do not buy Rear Proj tvs, Plasma tv, LCD Rear proj Tv, or Overhead projectors. Buy conventional tv or LCD monitor or tv but not rear proj. Some of these illuminate using a lamp device which has a short life span (approx 6000 hrs) = 3-4 yrs use.
