I have highlighted the 2 areas where there are finger screws that need to be removed to access the lamp. It is a bit tricky the first time the cover is removed but, once done you will have access to the lamp door. This is the same as model KF-42WE610 sold here in the United States. If the lamp has never been replaced than that is the suspect. Anymore questions you can email me at tvtek(@)msn.com

Well we need to have in mind that a generic lamp will give you 3500 to 4500 lamp hours and the Phillips will give you 6000 to 8000 lamp hours ,The lamp itself typically uses AC current and about 15,000 volts to ignite the lamp's mercury2.gif vapor gas. The gases inside the lamp react when electricity charges up the mercury gas creating very bright light. The voltage drops to keep the flow of electricity to the lamp.
The symptom of a bad ballast is that you could hear a constant CLICKING or electrical BUZZING sound,my recomendation is to take out the lamp to physically check for any sings,(shatter fillement,black or grey spots in the fillement or smoke ) you can get good deals at http://www.discount-merchant.com/?click=52978
Please keep us posted,

Recently changed my bulb for my Wega LCD KF-42SX300U TV. Since then it is turning itself off, with no particular pattern. It can come straight on and last for a few seconds, or last the entire evening....


Hello,
This is a classic case of a faulty lamp(even though it is new). Possible that it is a ballast(lamp power sply) problem but it is more likely that the lamp doesnt quite meet the required specifications. Your lamp may be a Non-OEM or a refurb. You should try to get it exchanged with the vendor you bought it from.
justlamps.com is a great source for bulbs.
good luck
