Default Need Help Diagnosing a DLP Problem

Hello, I'm new to the forum and hope someone can either answer or direct me to a solution.

Here's my specs:
Samsung DLP HL-S5087W Television.

Background
I've had it for about 5years and have replaced the lamp bulb within the last 2 years with a Phillips brand BP96-01472A.

Recently within the last month the TV was making a grinding/whisping sound. It almost resembles the equivalence of holding a piece of plastic in a moving fan. It continued to grow louder and more frequently over time. The sound would continue after the TV was turned off (via button on front or with remote).

Problem #1
I'd turn the TV off with the remote, the grinding sound would last roughly 5 minutes and then once the TV seemed to completely power off (I'm under the impression the fan keeps spinning once the tv is turned off) the sound would stop.

I'm guessing that the sound was coming from the lamp fan as i figured the color wheel and lamp shut off when the TV shuts off. Now if i removed the power cord the noise would stop instantly. The picture was fine and there weren't any error messages.

Problem #2
Today when i tried to turn on the television i received the 3 blinking lights. i shut the TV off and after a while (10 minutes) i turned it back on. This time the TV came on fine but the picture was significantly dimmer. No error messages and the grinding sound is few and far in between. What could the problem be, The Lamp bulb, the Lamp Fan, or the Color Wheel or something else? I've purchased all of the items, awaiting delivery of the lamp (Phillips), and have decided to replace everything, but i would like to know what the problem was/is for future reference.

My understanding:
MY assumption is the lamp fan was or is going, hence the grinding noise and the excess heat the fan is not dispersing is or did put a hurting on the lamp (hence the reason for the darker images). Thoughts?

Thanks for taking the time to help me out.

I agree with your diagnosis. I am no TV repair man but have been around for a while..
Not sure on the dim image, could be that set is designed to run on low lamp if there is a fan failure.. I personally would have been inside the set looking for the fan when it first started talking..

Only you know if you have sufficient knowledge and mechanical skill to attempt opening the set to fix it yourself so no advice on that front..

Good luck!

No clue. You had a fan making noise, you know it was the fan because it kept running after power down to cool the lamp just like any projector. After the fan failed the lamp was dim either due to heat issue or design (protection circuit) .

This is logical trouble shooting with minimal detailed knowledge of the inner workings of the unit or it's electronics.

It's time to replace that television. I owned a rear-projection DLP television for 3.5 years. After dealing with the problems of bad lamps, bad projectors and questionable support for the unit I replaced it with a Panasonic plasma and since then have not had to spend a dime on repairs or replacement parts. RP DLP units, in my opinion, are like dinosaurs just waiting to die because of less-than-perfect design and implementation of the technology.

I've owned my plasma for two years. My RP DLP started to show problems within 18 months from purchase.

You can pick up a flat panel television for under a grand these days.
