DLP TV Blown Bulb: LG RE44SZ21RD

I'm fairly certain that the bulb has blown in this set OR that the TV refuses to start up after 8,000 hours of bulb life. I THINK I can order and replace the bulb, but how do I reset the bulb counter (given that I can't get a picture of any sort at the moment). I assume that the counter needs to be reset before I'll get a picture, even with a new bulb.
Thanks in advance,
Matt.

How long do bulbs generally last?

Generally, a DLP bulb lasts about 8,000 hours (if a TV is on 10 hours a day, every day, the bulb will last about two years). A bulb can last longer if it's used less frequently. Typically, a bulb in a DLP TV for household use should last at least three to four years before it starts to flicker and needs to be replaced.

Thanks!

LG DLP TV Won't Start Up

After the bulb replacement, the lamp hour should be retested. If you replace the bulb, and after the lamp hour reset to new bulb; and after that you replace it with old bulb, it won't work. In most cases, the lamp ballast too have to be replaced with a new bulb, and it is a good practice too. If the TV refuses to start up, there are many reasons for that. It will be best to contact any experienced service technician; I suggest. If you wish to get some details; visit the site linked here. Pull up older posts. http://electronicshelponline.blogspot.com/

How does tv know when lamp is expired -changed bulb after yellow lighht came on but light stayed on months later the light went to red and tv wont turn on

When the lamp goes on a DLP you get no picture, if the light came on and you still had a pic then it might have been telling you ,you had other problems. If the TV wont come on now check your bulb it might be blown this time. The bulb will have lots of small peices of glass in it when its blown. They should last a few years each (3-4).

RCA SCENIUM MODEL D44LPW134 IS MY BULB BLOWN?

If this is a DLP, which I believe it is, your bulb is blown. Look for an indicator light on the front of the tv. After you hear the bulb try to warm up two or three times the indicator light should come on and stay on steady.
I own a 57" Mitsubishi DLP and have replaced the bulb three times now. It was the latest and greatest technology when I bought it, but knowing what I know, I dont think I would buy another DLP.
By the way, get the bulb number then check ebay, by far the best prices.

I HAVE A RCA DLP TV AND THE LAMP KEEPS BREAKING EVERYYEAR

Make sure the tv is at least a foot away from the wall so it can circulate air and keep the bulb cool. Try to avoid turning it on and off multiply times in a short period of time.

Re44sz21rd

HI,

All I can suggest is to replace the bulb. I experienced a similar problem after about 2 years viewing when the recommend lamp life was approx 8000 hours (I got to approx 3000 hours). There is a service menu you can access where you can reset the lamp hours time. I have read that if this is reached you must replace your lamp, but you can extended this by reseting the hours.

I have since learnt that a lamp bulb can go at anytime, so it is worth having a spare. Also I have noticed that switching the TV off at the switch (not leaving it in standby helps).

Try this to access the service menu. Holding down the menu button on the remote and the one on the TV for a few seconds. I think the TV needs to be off.

From memory, I think it is option 4 and option 5, then reset the lamp hours to zero

Hello pravinp,

Since this is a DLP set, The bulb becomes suspect. I would take the bulb out and measure the voltage in the socket from which the bulb was taken to determine if the socket is hot. If it is I would then take a resistance reading of the bulb, the resistance should be at 0 ohms. If your bulb is blown replace it with the exact type. The TV might be shutting down to prevent further damage from occurring

I hope this helps
