Hi,
Yes, if you have not replaced the lamp since you purchased this TV.
Lamps usually last about 6000 hours.
I've seen lamps last much longer than 6000Hrs, it all depends on the usage.
Remove the lamp from the TV and do a visual inspection, see if there's a crack on the glass or the bulb.
If the TV is few years old then the Lamp may be bad.

DO NOT BUY the lamp from ebay

Good luck to you.

Three red light blinks shows that lamp cover is not properly closed after lamp replacement. Make sure that the lamp cover is in its proper position. Try to reset the lamp cover and turn it on clockwise direction until you heard a click sound of a micro switch activated by the lamp cover, then put the set on..

the lamp may need to be replaced this is a symptom of a bad lamp

Replace Ballast Board it is what turns Lamp on! Call Encompass for Part 1-800-638-3328

If the second light is blinking to orange or red, that is usually the lamp indicator light on an LG DLP tv. That indicates your bulb needs replaced, or something surrounding the bulb has failed (like the cooling fan for the bulb for example) IF you have a spare bulb handy, I'd replace the bulb, keeping in mind if you touch any part of a new bulb with your bare hands, you just cut the life of the bulb by more then half.

It is symptom of weak Lamp in your TV, replace Lamp with following part number..
A1606034B LAMP BLOCK XL-2100U
It is available in Sony Accessories for $200
Always buy Sony Original Lamp for your Sony TV and avoid aftermarket/ cheap lamps.
