is it the lamp light shining out the back? or the lamp indicator on the front of the tv being on? if it's just an indicator light, there should be an option in your tv's set up menu to reset that light, generaly speaking unless something was forced, the lamp cartage will only fit one way, just make sure the covers are closed, if it working and the nag light is still on that should be able to be reset in the tv;s set up menu

Try changing the lamp, some times as they age the electrodes in the arc lamp evaporate and depositing inside the arc tube, causing it to darken, if the lamp is clear there is a good change that the light tunnel is broken or has other problems with the light engine

nothing else is required except inserting it right which is not hard==lamp does not seem to be your problem, Other things will cause this issue as well, it is not always the lamp that is bad.

One thing you might want to do is remove here the new lamp unit to make sure it went in clean and straight, With it removed look in the direction the lamp faces for the color wheel, look to see it is intact and not shattered, I attach a photo.

I mention as this is also a common issue in this set, usually proceeded by a high pitched fan like sound or even when failing a grinding noise.

Sounds like a shorted component in the power supply or the high voltage circuit.
Time to call a professional.

If this tv is a Samsung HCM4215W with the symptom you described you are likely to have fluid leak on the board. Sounds like a classic fluid leak problem since the audio does come on and then going intermittent. If you find fluid from the tube(s) on the board then the set could not be worth fixing unless you can break up the fluid with degreaser spray. The fluid is conductive and will cause intermittent or shut down altogether the set. Look for the fluid as a clear substance. Also you may have a bad proscan board (module) Comes on with audio and no picture then on/off REPLACE PRO SCAN MODULE BP95-00077A. Do a search online for part for availability. But look first for the fluid leak.

We have a Samsung DLTV that does this when the bulb needs to be replaced. We have to replace the bulb quite frequently. You can look up the bulb you need online using the model number of your TV. I hope this helps.

Your convergence has failed and needs to be repaired. Once quick test is to goto your convergence menu and see if you can adjust red and blue. If not its has failed and needs to be fixed. You can call in a repair shop or you can get the parts and instructions from www.TvRepairKits.com and do the repair yourself. Its a fairly easy DIY fix.
