It is in the newer software to lower convergence drive. In 2.13 it is absent.

There are also two versions of the focus module. One is longer and has a metal part coffering the heatsink until the fan. The older does not have that metal cover part. The tray does not even have the holes to fit it. Which one do you have?

One stupid question but do you know for sure you have a compatible eht quad splitter chain? Some combinations are known to oscillate or something.

I mean he paid but I have not send anything because he would come back to me for more.
It is now two months ago I am starting to think something happened to him.

I would not try to measure the feedback line its high impedance ,so putting a meter (load) on it will change hv output ,and you probably at noise to it to ,and the 1/1000 resistor divider can be the problem ,so only measuring the hv output can give you valid level of the hv . Image pulsing in and out have had that to in a barco data600 =faulty splitter= hv goes up and down , I would like to know if its the c on output thats dying or the divier thats dying ,the divider is very simple but if you do the math you quickly find out that doing it with a low dissipation you get very high impedances . (347megohms dissipates 3,47wat at 34,7kv) What is the value of that trimmer pot? For the curious like me here are some pics. Trimmer says 1M. The colour codes should give the values. There seems to be 320MOhm internal in the switcher.

I think there is a listed procedure for it in a SEOS manual, GregSTV recently forwarded it to me, and i passed it on for upload here. Either way im not overy interested in testing that side of it, but i would like to test and adjust the EHT board settings, ill have to grab a HV probe for my Brymen meter. In the 909 service manual under the EHT you can read how to adjust the two potmeters on the EHT. But you need a 1000x hv probe. Perhaps you can borrow one? P1 High Voltage Adj. P2 Hold Down - Switch off the projector - Put the fuse 2A on its place. - Switch on the projector - Adjust potentiometer P1 "High Voltage Adj." until the EHT voltage reaches 36.5kV. - Turn potentiometer P2 "Hold Down" until the Hold Down LED lights up. The projector switches at that moment into the Hold Down mode, picture disapears. - Put the potentiometer P1again in its minimum position (turning clockwise!!). - Turn the power switch in its OFF position (not-pressed) and switch on the projector again (press the power switch). - Adjust the potentiometer P1 for an EHT voltage of 34.7kV. Important: The EHTsplitter, on which a potentiometer is mounted , leaves the factory as a factory pre-adjusted unit. A readjustment of the mentionned potentiometer is in no case allowed. |

He bought parts from me december 2015 but has not replied on pm ever since.
