RCA D52W136D Throwing Error Codes

I have a circa 2003 CRT rear projection RCA Scenium model D52W136D that is producing the following error codes

72 (ten times) time stamp 007342:18

73 (ten times) time stamp 007342:18

44 (four times) time stamp 007336:35

33 (five times) time stamp 006797:02

37 (one time) time stamp 006536:09

The picture bleeds on white lines in the lower left corner of the screen when displaying a 1080i signal and any input DVI, or component. There is a visible color tear around whites and the picture is not as crisp as it once was.

Any help would be appreciated

I haven't cleaned the lenses or mirror. Anything to watch out for? cleaners etc ?

The first picture is that of my PS3 hooked up via monster hdmi to dvi cable 1m close up on the bottom left corner:

This picture is the menu from my Direct TV Receiver.


I appreciate the help.

I have done an auto convergence adjust in the service menu before and it always finishes with no adjustments needed. I also pulled the front speaker panel and I can see the CRT's and its pretty dusty inside. I am not sure how the chassis opens and pointers?

Thank you for your help I really appreciate it. I read on the link provided about a focus adjustment is that something else that may need to be tweaked?. After I clean it and hopefully go through the manual convergence process ( assume I access that through the service menu) I will post pictures again of the results. This TV used to be some much clearer and its not my eyes going.

I went through the 195 point manual convergence adjustment and things were WAY off. I tried to get it as close as possible. There are only a few areas that may need a little more tweaking but the results are great. The picture tightened up. I think I may still clean the lenses and mirror but for now its a 300% improvement pictures to come shortly.
