Sorry, you're correct - it does tell how to get in to the Service Mode - but it doesn't tell the additional keystrokes required to bring up the end-of-line manufacturing data that includes number of hours on the lamp, DMD engine temperatures, etc. For those interested - enter Service Mode by the following procedure:
a) Turn VOLUME down to MINIMUM
b) Press MUTE button twice on remote control
c) Press and hold MUTE button down on remote control
d) While still holding MUTE button on remote, press MENU button on TV set
This will enter the TV set in Service Mode.
Once in Service Mode - pressing CHANNEL SELECT up and down keys will select items that can be adjusted and pressing VOLUME up and down keys will change the value of the selected item.
Additionally, while in Service Mode, pressing the RECALL button followed by the number "9' button will display a page of parameters that includes: Power ON Time, Lamp ON Time, Lamp ON/OFF Count, DMD Engine Temp 1, DMD Engine Temp 2, and a host of other information.
A good manual would explain all of the designed-in fault limits and what the system response would be if encountered. Yes, the manual does give just two Fault Trees: One three page tree for "Lamp does not start" - and a second one for "Dead / Does not cycle". A good service manual would go far beyond just two faults and describe a host of things that might go wrong and how to fix them. A good manual would describe detailed circuit functionality and what type of tests could be applied to isolate faults - at least to the module level and in some cases to the component level. This manual doesn't really live up to its title of Service Manual, in my experience.
As you say, finding modules may be getting more difficult, but I am having trouble confirming which module is faulty, so that I may try and find a replacement. I have read where people have replaced two, or even three modules, without fixing this problem. That gets to be a very expensive, time consuming and frustrating proposition.
Apart from the difficulty I am currently experiencing, I do like this TV set and would be more than happy to repair and retain it, if possible. To that end, I am still interested in a specific diagnostic test that would confirm which module, or component, is faulty. Perhaps you are right again, in suggesting it may be time to look for another set.
Many thanks for taking time to respond with your advice and for correcting my error.
