Well to be honest with you it could happen if you purchase a generic bulb they will only last around 1year to 1.5 years always buy Philips the other problem that you may have could be the ballast board if for any reason it is sending to much voltage to the lamp it will make the lamps burn out much faster
If you want to fix this problem I would replace the ballast board ( around $60.00dls - $80.00dls) and also replace the lamp ( $115.00dls - $140.00dls ) this store has the Philips lamp

    Lamp life is based upon usage hours not calender time. If the set is heavily used, than it is possible that your replacement period is correct. It is possible too that the ballast is slightly defective and is causing excessive stress to the lamp. This is extremely rare however. Check to be sure that there is proper ventilation for the lamp. Its lifetime is shortened quite a bit if it runs hot. It may not be hot enough to trigger a temp shutdown, but may be hotter than standard. Cleam of the vents and make sure that the fans are all turning properly as well.

What do you think should be right. If there any loose solder terminals to the ballast bard, this type of fault can occur. Anyway, I'm not sure about it; but check this frist before doing any other. Gopakumar Gopalan Google

On/Standby light flashes red four times


These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

hey, most common faults usually overheating with that fault, restart the pc, go into bios usually by pressing del or f2 button on the black screen and look up hardware monitor tab and check the cpu temperature if its around 60c that will be your problem, and will need a new heatsink and fan fitted.
other thing to do is hard drive test you will find the diagnostic tool on the manufactors website.

You have a problem that is destroying your "Bulbs" this is NOT normal at all. This is indeed a problem when people aren't experienced enough with technical matters. You see the "Bulb" is a Symptom, of the actual "Fault" NOT the main cause. This, "main cause" MUST be fixed FIRST, before one replaces anything, otherwise what you are experiencing, will simply happen over and over again, and gets more expensive that if one had of sent it to a reputable service centre/man in the first place. We really ARE worth our salt.

Driver-side headlight bulb burns out every four months or so. Passenger side is fine - same bulb for a few years now.


Hi:
four months is way too soon, so you need to look things over a little closer. The entire headlight assembly could be slightly loose, and vibrating on bumps and causing the bulb to die. Next time you put a new bulb in, buy and use some dielectric grease on the contacts of the new bulb, to keep moisture out, and examine the harness plug for signs of dust, dirt or corrosion. since it takes four months to fail, it has to be a minor thing.
