That sounds like a Hitachi model number. ON the front, to the left hand side should be a panel that you can remove to obtain access to the lamp. Most likely it'll be embossed with the word, `LAMP'.
The lamp is a piece of equipment that is built into your LCD TV. This lamp is what brightens the screen on the television. The bulbs for this lamp can break and need to be replaced.
LCD stands for Liquid Crystal Display. LCD television have bulbs, used to illuminate the high-definition on-screen images and thus need to be replaced in a period of time. Installing LCD television lamp is user-serviceable.
The projection lamp, from the sound of things.
Average lamp expectancy is about 2000 hours. If the TV shuts off the lamp intermittantly and then powers back on after a minute or so, a lamp change is probably in order.
If it's a TV that uses a projection lamp, then the lamp or ballast is going bad.

The lamp can't be 'repaired', it is always just replaced. I would contact the store where you purchased the TV and see if they can order you a replacement lamp. Most TV's can be re-lamped by the customer.
The average cost depends on the size and wattage. The average life of a tv lamp is eight thousand hours. Here is more information on prices: http://www.dlptvreview.com/dlptvreviews/projection-lamp-replacement.html
Power consumption varies between individual models, but LED-backlit LCD televisions typically consume less power than plasma televisions.
A DLP lamp may need to be replaced because it may have become faded or have burnt out. DLP lamps are often used in HDTV, LED and LCD televisions for picture quality.
Rear projection TVs are powered by a high-luminosity lamp. This lamp shines light through an LCD screen, creating an image on a rear-projection TV screen. Many TV lamps have a limited lifespan, requiring replacement after several thousand hours of use. When replacing a TV lamp, find the model that works for a certain TV brand. After purchase, locate the access panel on the back of the TV. Remove the old lamp, and clear the area of all dust. A great way to clear dust is with a vacuum cleaner or compressed air. Install the new lamp, and replace the TV panel.
Does it even turn on? Is it the projection lamp type or a flat panel LCD set? If it's the projection type, you may have a lamp that's finally gone out or a bad ballast unit. The other things that can cause no picture is if you have the wrong input selected on your set via the remote control by which, the TV is looking at an input where's there no signal present. Most TV's though, should display something though, such as, `input 1', `input 2', etc.
