After over a year of flawless operation, I turned in my projector and got a "No Sync" message on the screen. Unpluged RGBHV cables from projector and pluged into a monitor which worked fine so must be something in projector. Any suggestions? What simple things can I try first?

you can try clening the electrical contacts inside the machine. It's talked about in this thread.

You might also consider having the control module re-built and possibly the rest of the machine.

Probably a good cleaning and reseating of all the boards is what's needed.


Here is a link to parts and boards of the Marquee. Reseating of the Focus board and HDM is just pulling it out and putting in in a few times to clean the contacts, you dont have to remove any connections to do this. Just pull up and put back in a few times. http://www.curtpalme.com/Electrohome...e_Layout1.shtm


Location of FCM and HDM.

on the hdm their is a daughter board that also need to be removed and reconected.

Next on the CLM there are some chips that can be taken out from their

sockets, do one at a time. you will need a IC puller from radio shack to do this.


Location of CLM:

CLM out of Set showing chips.

chip puller pic:

Clean all chips with some contact cleaner or Denatured Alcohol.


I use DeOxit:

Do one chip at a time and remember how it came out so you put it back in the same way.

Yep.. Did the Curt Palme Marquee Teardown once before about a year and half ago when I was having a convergence problem and fixed it then so here we go again.... WoooHoooo!!

if you already de-oxidized the connectors a year ago I will be surprised if it fixes it again. Oxidation shouldn't really build up that fast except maybe in sub-tropical climates

Did someone select the wrong input perhaps. Press 'source', 01.


Mebbe a kid/wife thought source 02 would be a good idea.

 

[jdschwartz]

Curt - I don't let anyone touce the projector remote, but I will check to see what source it's on.


So I did a complete teardown and put it all back together and now I have NOTHING! I cant even get a menu on the screen. Any suggestions? I'm about to repeat the teardown again to see if I simply missed something or if something is not quite pushed in tight.

Orange standby light on control module( back of PJ) lit up?

 

[jdschwartz]

OK.. So I forgot to reconnect the RGB mini-RCA jacks back into the VIM. So now I at least have menus. But why are all my menus upside down and backwards?

 

[jdschwartz]

OK... Got sync and got picture.. WOOOHOOO! However, the picture is upside down and reversed. I will search through the forum and will post another thread regarding this.... How do I reverse the horizontal and vertical scan?

 

[Curt Palme]

Your H and V yoke connectors are reversed:

OK.. I had the 3 Green/Yellow connectors reversed on the main circuit board. All is good. Thanks everyone for your help.
