I have a Mitsubishi wd-62525 and I am having trouble with the lamp, here is the story. I got this TV from a friend that was getting rid of, when I got the TV I opened to see what was wrong with it and found out it need it a lamp, I purchased the lamp got it a week later and install it. When I installed the lamp I noticed the TV was not turning on, and it made a clicking noise, that noise that you hear when you hear sparks the same noise that you get when you are playing with electricity or turn on a gas cook top. I opened the TV again and reinstalled the lamp and the TV started working with perfect picture. 3 months later the picture started to lose brightness 2 weeks after that the TV was very dark and you could not watch TV it was too dark, so I removed the lamp and reinstalled it, the picture was the same, dark. After a few days when I turned on the TV, the TV started to make the same noise it made at the beginning the spark noise and then showed the red lamp light, after that I noticed that the spark noise was the lamp making a very low flashing light and then shut off. The TV never turned on after that just sound.
I purchased another lamp installed it and it worked right up for about hour, after that the TV suddenly turned off and the red lamp light appeared, when I tried to diagnose the problem (I removed the lamp door) I see that when I turn on the TV, the lamp turn on for 5 seconds then off then on for 5 seconds then off then on for 5 seconds then off and then the red light appears
I was reading the previous posts and checked the capacitors to see if they were swelled or leaking and they are ok
Any kind of information is greatly appreciated
