50" Samsung DLP HL-P5063W with 3 Flashing Lights on Front

My broken 50" Samsung DLP HL-P5063W has 3 flashing lights (Timer, Lamp, and Stand By/Temp) on the front of it. There is no picture. It tries to start up 3 times and then just has the three flashing lights. Here is my YouTube video of what my exactly what DLP was doing:

Many people talked about a loud squealing noise when the color wheel goes bad -although as you can hear in the video -there is some noise there, but it's not really loud. It sounds like the color wheel never gets up to speed -and you could feel pretty significant vibration in the DLP chassis when it was trying to start up.

1. I replaced the lamp (from Amazon) Samsung Replacement Lamp with Housing for Samsung DLP TV

2. Then the Samsung BP47-00037A Lamp Ballast / Driver | BP47-00033A BP47-00029A ballast from Discount Merchant (http://www.discount-merchant.com/p-146818-samsung-bp47-00037a-lamp-ballast-driver-bp47-00033a-bp47-00029a-bp47-00029a-1-468-927-12.aspx or Amazon - Samsung BP47-00037A PCB, Ballast, Lamp, EUC132DP/41).

Both the lamp and the ballast are easy replacements if you don't mind unscrewing the back of your DLP and removing a couple cables. Unfortunately neither were my issue this time.

3. Ultimately it ended up being the color wheel that was the issue on my DLP. I purchased the replacement from Discount Merchant. http://www.discount-merchant.com/ProductDetails.asp?ProductCode=Samsung-BP96-00674A-CW-ENC

The process getting to and replacing the color wheel takes about 20 minutes. It can be a DIY project. I used the guided instructions provided by the fix your DLP website (FixYourDLP.com Samsung Color Wheel Instructions). As long as you comfortable with screws and computer connectors -it's not a big deal.

Here is the picture of my color wheel after I extracted it from my DLP. The bottom of the housing was filled with the missing glass. It was very obvious once I got to it that it had failed. Almost 1/2 of the color wheel is missing in these photos. Now I know where the vibration was coming from. If this off balance wheel was trying to spin up to 9000 RPM -that would make for some nasty vibration.



I did make one mistake and placed the ribbon cable in backwards (didn't work when first powered up). This picture below from the guide clearly shows the ribbon cable silver side out:


General feeling from the family is that the Samsung DLP looks as good if not better than brand new (set is about 6 years old). The picture seems much brighter and vibrant. I now have a spare lamp and ballast for the next time it has issues. Hope this helps someone out!

UPDATE 1/6/2013:

After replacing the color wheel myself, we noticed green cast showing up in what should be black shadows on the TV. We lived with it, because some people online suggested that the analog board may be going bad on the DLP.

Turns out by adjusting the "Index Delay" in the service menu I was able to get my picture completely black again (no green cast in the shadows). Here's the process I followed:

1. Turn the TV off
2. Press "Mute"-> "1"-> "8"->"2" "Power" on the remote to tun the DLP on in service mode (you can do lots of bad things here -be careful)
3. Highlight the first menu option "DDP1011" using the up and down arrows - select using the left or right arrow
4. Highlight the "Index Delay" option using the up or down arrows - select using the left or right arrow
5. Now the index delay screen was visible with a red bar at the bottom (I wrote down my current value (46 in my case). I used the left and right arrows to select the minimum of red range. From where it looked Magenta (24) to where it stopped looking red (48). The service manual said to then use the mean (or average) of the two values ((48-24)/2+24=36). I moved the left and right arrows until the value read 36.
6. Turned the power off

Restarted the TV and my green cast in black shadows was gone. Awesome. Hope this helps someone else out.

UPDATE 6/6/2014:

I ended up with the three flashing lights, but no wierd sounds. The TV was acidently left on for awhile - perhaps 12 hours The TV wouldn't respond to the front power button or the remote. I just unplugged it and let it sit overnight. The next day it fired up like normal. We'll see - it may nee another bulb replacement (http://blog.trebacz.com/2009/12/quick-replacement-of-bp96-00826ap-bulb.html) after five years.
