Replacing the color wheel on my Samsung HL-R4266W DLP

Our Samsung DLP HL-R4266W started making some noises which made it unbearable. The noise would come and go at random times. I found that pushing the back of the TV would make it go and used a temporary workaround for a while until it came back with a vengeance!

So, I searched on some forums and on Google and I ran across several posts on how to do it yourself. I also called a technician and found that it would cost me about US$ 400,00 to replace it via him.

So, after finding a few posts and videos about it, I decided to do it myself (links at the end of the post). I found the right part number for my TV from the Samsung website, found a cheap one on EBay and bought it.

I am posting below some pictures of my process, although not complete.

1. First step is to remove the cover of the TV to expose the back. I marked the cables and screws I had to disconnect with a red circle:



2. Take out the display lamp by removing the screw and pulling it out:



3. Pull the optics module out slowly and watch for the cables on top and on the left side. Remove the big fan on the right side. Next, disconnect the cable on top of the lamp housing:



Remove the lamp housing by removing the three screws and slowly remove it:



4. Disconnect the two cables from the color wheel:





5. Remove the two screws holding the color wheel in place and pull it out. Here's my old color wheel:



Here's the new color wheel:



Not much difference between them, but spinning the old color wheel resulted in some small noise.

6. Do the steps above in reverse order. Hopefully you didn't miss any steps and your TV is back working like a charm.

After the fix, my TV is much quieter than what it was before.

Here's the link to the other posts that helped be get this done:

• The closest to my TV model: http://kploymp.net/dlp_cw.aspx
• Great tutorial, slightly different in some places from my TV: http://www.jangro.com/electronics/samsung-dlp-replace-color-wheel/
• Lots of pictures: http://guides.fixyourdlp.com/samsung/bp96-01579a.php
• YouTube video: http://www.youtube.com/watch?v=Cx4pbNjsxfU

I recommend you do this slowly, taking notes and pictures, so you have a reference in case things don't go to plan or your TV is different. Good luck if you decide to try.

Web site updated

Just to inform that I updated the main page of http://winplanner.sf.net to point to the latest download available, so people don't download version 0.14.1 anymore.

I will try to update Planner again soon. Work has been taking my time.

Gantt crash

Well, it seems like the latest version of the Planner code in CVS no longer suffers from the crash. I will check the reported the issues again and see if this is fully fixed.

It seems version 0.14.1 will be released soon, so I will make that available once the official release is done.

Status

What's going on? Well, I haven't had much time to work on WinPlanner, but I started porting it from libgnomeprint to new printing support in GTK 2.10. So far, it seems to work so far, but Windows still doesn't have a version, so I cannot tell you how well it works there. Tor Lillqvist (tml) says a version is coming soon.

As for people reporting the Gantt crashes, I've recreated them and it seems like I need to recompile the libgnomecanvas with a later version of the code. I will try to do that this week and see if it fixes the problem. If so, I will release a fixed version.

WinPlanner 0.14 released

Please report any problems not related to native printing.

Working on Gantt alignment bug

I have been helping in fixing the Gantt alignment bug that causes the Gantt chart and the task tree to be disaliagned. I think we now have a solution that will work for everybody.

I will try to post more often as time permits of course.

Windows native printing

I'd like to hear everyone's experience with native printing on Windows.

If you get funny characters printed, then your printer is doing font substitution. You need to change the print defaults... in the printer settings and find the font substitution settings to disable it.

Please post comments on your experiences. I may take a look to see if this can be fixed.

New version

Just released a new version. You can download it from: http://sourceforge.net/project/showfiles.php?group_id=135505&package_id=148812&release_id=393294

It solves the problem of HTML exporting and contains all current code from CVS as of today.

Sorry for the delay (been too busy with work).

What's going on?

Well, I have been submitting patches for the Windows compilation. We are almost there. Jani Tiainen has also submited a patch to allow the application to run from any directory, so that will help as well.

Aside from that, I have also:

• MS Project 98 MPP import: working on a plugin to import MS Project 98 files. Working but needs a little more work
• SQL support: Jani and I have have been experimenting with the SQL support available on the Linux distros. It mostly works but there are some issues like resave problems and only PostgreSQL.

I will keep you posted.

New version released

Just released a new version. You can download it from:

https://sourceforge.net/project/showfiles.php?group_id=135505&package_id=148812&release_id=318410

It fixes some problems found on non English systems where Planner would lock up.

Planner 0.13 for Windows available

You can now download Planner 0.13 for Windows from its website: http://winplanner.sourceforge.net

Enjoy it!

Getting ready for release

Got most of the development packages ready to release. Now I am cleaning up my changes to planner as I got lazy when I've done some of them.

I also need some space to place the files, as my personal webpage can only hold 5MB. Anyway, if you want to get ready, make sure you have have GTK+ 2.6 or later installed on your system (already required by Gaim and Gimp). You can get it from GTK+ 2.6.4

Also, libgnomeprint now has native Windows printing, although it still has a few bugs in it (depends on the printer, etc...).

Planner on Windows

Here's a screenshot of Planner 0.13 running on Windows:



Enjoy, it is coming soon.
