Versed, you have to open the back panel (cover) to access the lamp. replacing is easy as soon as you can see it. loosen the mounting bolt and pull to unplug the lamp from the SMPS Lamp power supply. Thats it.

your backlight burnt out, this will be a maybe several hundred dollar repair. the screen is backilt by a very expensive flourescent light, without that light, the screen will be black.

You need to pull the front grill cover/panel off the front of the tv. Remove screws (4) from back that hold it on, also 2 small ones behind front video input door. Then remove access panel. The ckt board closest to you is the convergence amplifier board. You should replace both amplifiers (stk392-110 or 120) and any burnt/open resistors you find near the amps.(use the same value resistors as the corresponding resistors in the blue amp ckt)

That problem is usually cause of bad capacitors on the power supply section..
As you stated your TV works fine and after a minute the red light comes on...
That symptoms is cause of bad capacitors..Normally bad capacitors can check visually if the capacitors look like leak/bulged on the top that is the indication of bad one but not all bad capacitors are bulged some are not so in that case you have to used a special meter called capacitance meter..
This is the sample picture of bulged capacitors:
