My Cinema9 is being used as a test bed , and was working with all original barco boards two weeks ago.
I always need this PJ to be in good normal condition to test boards and to harvest parts.
I left it off for two weeks to attend to my regular day to day activities.
But previously or two months ago ,this unit has a tendency to have no video , even if there are no scan fail indications. The G2 diagnoistics will have no red led and the rgb switcher board will respond to my remote and have green leds on and off. The solution was to keep alternately swapping the g2 diagnostic board to get it working. And so i thought it was all good to go. i used it for the next two weeks to check on my DIY splitters without suffering any shorts or scan fail. Then put back the original Barco splitter, double checked for the next succeeding days that all is normal, then left it off for the next two weeks until now.
I have swapped out all the HV parts, and smps, and tried on another new barco splitter. Tried the g2 switch again and again.
Decibel had an almost similar issue, for his situation it was the eht board. I have four good eht swapped in and still no go.
it is as if the three crts are not connected to the splitter, though the splitter's sub board does measure 33.7 volts, and no red leds on all eht boards used.
wildone: I don't think the B chip is at fault. The lead-free manufacturing process and solder balls used are more likely the culprit as the BGA still works after reballing

gjaky: Hi Craig, Why do you need it? I mean with multi channel amplifiers all channels are the same, it is usualy possible to find at least one working channel so you can identify (or at least guess) component values for repair

craigr: Actually, I have been unable to find schematics or a service manual for the Lexicon LX-7 or LX-5 amps. Of anyone has a copy I would highly apreciate it.

analogrocks: Those are pretty pictures! Set one up running a ps1 or NES and sell them as retro gaming projectors. OR post them to me. Just put the stamps in the corner. Should make it just fine

lfcfan: Hi Todd, have been reading endlessly about the topic, and I really don't think that I'll be capable to 1. do the job myself as I don't have enough of the right equipment, and it looks like only the people who have access to TI exclusive distribution networ
