I bought a very used ECP Graphics projector several months ago, no major problems until now.


After starting it up I can watch HTPC video source perfectly well for a minute two, then it displays "Converging...Please Wait" every 13 seconds or so. It's worse than popup ads! The picture is otherwise fine.


I thought it might be overheating, but the fans check out OK and it does the same thing with the case open. The service manual says that I should see a red light on the back panel if there is a failure with one of the memory chips, but I only see the green "ready" light go on and off during the convergence.


Any suggestions as to what I should try? I have reasonable soldering skills and access to an oscilloscope if need be. I live in the SF Bay area, in case anyone knows a good local tech, but I'd much rather try fixing it myself since the projector is so old.


Any help appreciated,

The problem has gone away but I'm not really sure why.


I pulled most of the cards out, dusted them off, cleaned the edge pins with "color tv tuner cleaner" (works great on electronic parts with moving contacts) and reinserted them. I also pulled out the known-to-be-bad-but-never-use composite video input card and left it out.


The wife said, "Oh, you fixed it!" but I didn't really fix anything. Guess a little Spring Cleaning can go a long way with these old projectors.

Yes indeed. You probably *did* fix it. You'd be surprised at how many evils a simple board removal and installation will fix on the ECPs!
