Panel is bad. Contact Samsung to see if they will replace the panel.

you most likely have a bad light engine.

there is a burned-in spot on the polerizer light filter for the blue lcd. it makes sure the light is blue coming through, that's why it is black on a blue screen, and yellow when the red and green are the only light showing through. it needs to be replaced. pat # PFiLW0213CEZZ.

You have a problem with the light engine. Hitachi has extended the warranty on some of these. This is a major expense with major labor charges. Better get in contact with a local Hitachi authorized repair facility.

its sounds like the guns has burnt your yube, when switching of does your tv show a bright circle in the middel, or while watching. Smack your tv on the side while on see if the picture goes away or make a bright circle in the middel, this is caused by a bad solder joint but you wont get rid of the bunt pixels sorry.

My nikon coolpix 4500 has the flashing red clock as well with the hands of the clock pointed to 9 oclock and a white dot on the oppostie side of the 9

Hello BruceD,

What you may have is a magnetism problem. I would suggest that you try deguassing the CRTs first before looking into replacing the CRTs. You can have a TV technician perform this for about $50.00 - $60.00.

Thank you,
