HI Guys,
I have the Cinemax with me that i suspect has a bad focus board.( The video went soft and there is a horizontal band on the image that seems out of focus ). Adjusting the focus from the menu is possible but it is maxed out already, for it to get a decent focus. I have been using this unit with a fresh 808 quadrupler from the Crt P.
With the 808 quad, the PJ Probably have logged 30 hours already or more.
Is it possible the 808 quad can ruin a 909 focus board?
The Quads' focus leads have been terminated already and the eht is a 909.

And your wife should be happy to support your hobbies and interests, otherwise you need to find a wife that does. Relationships are not about sacrifice, theyre about happiness shared together. How often do you tell her she cant do what she likes to do??? He he he, Well said Case. Actually she is quite a good sport about this, me spending a lot of time and money on crt Pjs and other related hobbies. She has learned to appreciate crt Pjs over plug and play TV sets. My wife and most Girls can discern good picture quality with out being too jaded or overwhelmed by technical mumbo jumbo. I would always watch with her, the girl/ drama/ light comedies and doze off to sleep. hehe. I really seldom can watch movies for long or continuous periods, its the setting up and all the work to get it running smoothly, that i enjoy. So it seems i am the kind who likes to tinker and tries to get reactions from friends and family about the job i've done. This is still very fun for me and my family does seem to prefer me doing this than any other hobby. WAF is quite high so far,

PS, did you get onto Greg about getting a NEW quad from him? Yes ,and plan to get one but i hope its all worth it. Cause another one quad down and my wife is leaving me.

Guys, To complicate matters more. just finished setting up the 909 i got from Curt hours ago, on the start the 909 was a bit erratic and video was modulating a bit , the green was not focused or sharp enough. Green crt is a lug03xxx 43. Looks new based on the stickers and labels. Now 5 to 6 hours later , losing the video or the video was modulating more. Eht led lit up , dying quad again. Started it up again , video came back but still modulating. here is where i stop. The good news,the green crt seems to be sharper now. the bad news is all four quads are dead. This is a big mystery,what gives. Video processor now is a radiance xe with the moome card. All 909 parts were the original that came with it, quads came from a 919 from curt also. Is the little white wire connected properly at the main board and to the splitter? Yes , you mean the mini coaxial cable. I did missed out on it before , the effect was the pj would shut down sensing a short in the system.

What is the voltage coming out of your wall outlet?

I was really only joking. I just thought it was funny. I guess it was just dry humor. But, when I said to check voltages on the EHT I meant "all" voltages, not just the 300v supply. And I am not sure that supply comes directly from that section of the PFC for that test point. There is either a contradiction in the manual or there is a 300v supply AND a 380v supply. Since I do not have a 909 to verify I figured it best to test right on the EHT connector. If connector is not accessible just use tiny fly wires. Size of wire does not have to be of a certain. You are only testing for correct voltage,not drawing much current. Note generation of 2 different supplies. But they supposedly exit though the same connector. Very confusing. These are from the same 909 manual. Is the "input mains" the same board as the "PFC". I can have a tech guy do the measurements for me, but i rather do the board swapping thing to isolate the problem, to save on work hours. Barco parts can not be that inconsistent to vary from 6 hours of use to 20k hours. My old cinemax has more than 10k hours running time, with only standby board failure. The quad i bought was a new old stock also.

I would be testing all voltages coming into the EHT board. Just be careful. To my understanding that is the voltage that comes direct from the PFC. There is a measuring point on the PFC. I once measured there to see if I had the right voltage something like 380V dc if I remember well. The PFC has a current sense that adjusts this voltage. There could be a problem there. You need to measure M102. But it is next to grnd measure point. I would suggest soldering a wire. I tested 224 volt dc on the m102 test point is this allright?

Just measured the test point m102, 224 + volts dc , w/ or w/out the eht and quads on the pj. I tested my working 909 pj, it also measures the same 224 volts dc.

Stop buying used parts will be my first suggestion... I will try to get a quote from Greg, but would have to figure out what is frying my hv section , esp quads.

I will report right back about the test, Just don't test on the quad itself. Test on the EHT only. yup, saw it done by a tech friend on another pj many years ago. it is very lethal.

I would try this, seems easy to do. My worry now is more on failing quads than eht boards. I understand that this test affects the eht circuit more than the actual quad. The quad will only fail for 2 reasons. To much voltage being sent to it or the quad was going bad to begin with. Well maybe something with the focus circuit but that is a little reaching. I will report right back about the test,
