The TV will be sensitive to Electro-Magnetic Interference (EMI)
Move the television away from interference causing equipment, this would be appliances with motors, radio transmitters, audio speakers/amplifiers, (receivers are no problem,) and florescent lights. You can try to eliminate any possible cause of interference by switching gear off one-by-one until you eliminate the lines. If you identify a source, then relocate it or the television away from each other.

Reset the rear projection television if you continue to experience lines. Each television resets differently.
Here is a link to the Servcie manual for the 53UDX10B 53" model, perhaps the reset ins. would be the same for yours.

When you follow the link below, look near the bottom of the page for the words "Get Manual". When they are underlined and become a 'clickable-link' then click on it to receive the PDF.

SOURCE: Broken screens on 53'' Hitachi rear-projection TV

I think it would likely work if you trimmed it evenly around the sides in order to maintain the central position. Focus may have to be adjusted but thats all.

Red Lines on Screen


Dave, HMMMM Dual pictures This is a problem that every projection TV runs into at least once or twice in its lifetime. Its the old convergence IC falure thingy. These IC's go bad and should be replace all at once. These are not consumer replaceable unless you have had training in the electronics or TV repair fields. Please call out a pro to assist you with this repair as A TV is not the place to experiment in because of the HI voltage and saftey issues. Good Luck
