The tv switches on and the screen comes on, but then it goes out and the lamp light flashes like there is a problem with the lamp, but how can there be if the lamp lights up? Lamps either work or they dont?

Ebay lamps can cause this as they are not originals also the balast supply, is gas discharge type, can fail.

that buzzing is the high end power trying to turn the lamp on.... the electrical current and shock is what turn your lamp on your tv which is what the buzzing is dont worry thats normal...however your solution is buy a new lamp for your tv but make sure its the right serial number for lamp u cant just buy any lamp. best place to buy one ebay.... as in the lamp still trying to light up its only because the electrical current going into the lamp and then cutting off causing the red light on your tv....so other words all it is is the lamp... CAUTION!!!! those lamps get up to 400 degrees unplug tv to ensure no electrical current.... hope i helped.... JACOB WINKLER

check to make sure the lamp door is closed properly, sometimes the sensor doesnt get triggered all the way

Replace the lamp would be the first thing to try. Lamp door switch on this model is notorious for going bad. If you replace lamp and still won't turn on jumper door switch. If you take off back you can see switch board.

Replace your lamp if you had it more the 3 years.

Those lights flashing mean the lamp is the issue. You need to test it with a meter. If the lamp tests ok then it may be the ballast is bad and that is what powers the lamp.
