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,
MY DOG SAW HIS REFLECTION ON THE SCREEN WHEN IT WAS NOT ON SO HE WAS HITTING MY TV HARD THINKING ITS ANOTHER DOG BY THE TIME I GOT THERE IT WOULDN'T START,THE BULB WAS ALSO BURNT SO THEN I CHANGED THE BULB NOW THE COLOR IS YELLOW AND PURPLISH I CAN'T GET THE COLORS,CAN ANY1 HELP???

The projection bulb came on,but didn't stay on mean the bulb have problems,dosen't mean projection bulb it still good.First must replace a new projection bulb to make sure for the elimation for the projection bulb is the problems.These DLP tvs require new projection bulb every 1 1/2 or 2 years by watching the tv like 4 or 5 hours daily.So there no lost there for trying a new projection bulb alway can save it for later use.The secound could be the board that call the Ballast board have problems too.The Ballast board only job it is to ignite to the projection bulb and make it work.Replace the Ballast board too,if the tv new projection bulb react the same way.
Lamp could still be going out they only last for 5,000 hrs some 8,000 playing hours.
Check the Lamp Fan if it stops running when Lamp turns on set will turn OFF.
But if you have never replaced Lamp Problem will be the Lamp Mats Has them for $99.00
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.
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/
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).
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.
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
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
