Need to reset the lamp timer for my Toshiba 46HM95.

If you are connected to a HD cable box or sat. rcvr. using component cables, I would then suspect a loose or bad blue connection or cable. If you have Comcast and have their supplied flat component cable this is a common issue.

Change lamp fan #23587525

SOURCE: still dark after replacing lamp

possible ballast problem or cooling fans not operating

SOURCE: Vertical lines across the screen

I now have the same problem. Lines are on the left side of the screen almost have way across the screen, with a thicker line int he middle which is the same length. It started last week and stopped after fiddling with it. Now it comes on fine then about 5 min . in the lines appear. I have had the tv for 1.75 years myself and have had to deal with bulbs popping numerous times (3). Was this the same as yours? Did solutions work? Please do tell.

I do not think failing to reset the Lamp Timer would cause the Lamp not to light. You need to get into the Factory Menu while the picture is on in order reset the Timer. I believe you have a Ballast issue either because the Power Supply is not powering the Ballast or the Ballast not Powering the Lamp. In either case, the only way to know is to have a professional to check it out and give a estimate for repair.
I hope this helps,
