Lately the TV has been taking a long time to warm up and display the picture. Now it frequently loses the picture. It will go from displaying the picture nice and clear and well lit to suddenly going blank (dark screen). The green power light on the front of the TV keeps blinking. The DirecTV box is still running just fine. Sometimes power cycling the TV gets it going again but not always. The TV is 6 years old and has not had an unusual amount of viewing. I have not noticed the brightness change.
Sounds like your picture tube or bulb is going out. It depends on what kind of tv ( rp, lcd, plasma) it could also be a component issue.

Replace the thermal fuse part# 1-910-006-44 You can verify this by jumping the connector where the fuse connects and the lamp will come on.

Hi...I am sorry to say that I had this exact problem. It ended up being the upper and lower panel drives. I contacted Hitachi and even though my unit was out of warranty, they agree to pay for parts. I paid for labor myself, and it cost me $199.95.
Good luck with it...let me know how it turns out for you.

Our Vizio started doing the same thing after only three weeks, except it was also showing green pixel when we watched DVDs. After checking this site and others and trying all the "tweaking" advised, I finally called Vizio's customer support. They were extremely polite and tried to help over the phone, but had to send someone to the house to make the repair (anything 40 inches or larger earns a house call). The tech arrived on time and was extremely professional and pleasant -- he had to replace the daughter board and LVDS cables. So far, so good.
