Removing connection with the controller (J5), gives me a reading of 0,24V on both pins (1 and 2).

Alright, with exception of the EHT, quad and splitter, all boards were swapped. I even used another chassis, to rule out the mainboard too. Unfortunately, with the same result. So I put the second fan-board with the diode mounted (from the backside of the projector) into the conv. tray, changed the S1 jumper to "front position" and took some voltage readings. On the AD7416 chip, the following reading were measured: Pin 1=1V Pin 2=4,2V Pin 3=4,4V Pin 4=0V Pin 5=0V Pin 6=4,8V Pin 7=4,8V Pin 8=4,8V Input diode D4=7,3V Output diode D4= 5,5V

I will replace all boards indeed, to rule out a hidden I2C bus error.

Thanks for your time guys. Some update. Putting the S1 jumper from the focusboard on +12V position didn't changed a thing (still voltages diagnostics option only, no temp. diag.) I measure 1,88V DC on the diode output, and is not broken (OL reading when change polarity). Position of S1 jumper is the same on both boards (front). Yes, both temp. and voltages option should be present in the service menu. Here a screenshot of Redfox's projector showing that. If I remember correctly, it was with CineMax V2.13 software. Could be the only soft. version that recognise both options ?

Thanks for the input, Dummyload. I'll play tomorrow with the jumper on focusboard to see the outcome. No I2C bus errors detected. Besides, I have tested both boards in another Cine 9, with the same behaviour.

Hello gents, I'm scratching my head about the fan speed-regulator (R763706) in my Cine 9. There are two revisions of them, the newer having some mods done by Barco (addition of a 2V diode near R8 resistor and another value of C5 cap.) When mounted in convergence tray, the older revision gives me "Temperature diagnostics" option in service menu, but no "Voltages diagnostics". With the newer revision mounted, "Voltage diagnostics" option shows back, but no "Temperature diagnostics". Is always one or the other, never both options present. And is not controller dependent (tried with diff. controllers and soft. versions). Projector is working flawless with both and I let the newer revision in (more important to keep an eye on all voltages rather then knowing how hot the projector is), but still..... I would like to get both options. Do you guys with electronics knowledge have a clue ? Mac ? Dummyload ? Greg ?

It means the 17v rail has a under (or over) voltage. He should tweak P100 on SMPS for a reading of 17,5V at J8 testpoint. Led D253 is always off when the projector is not starting, indicating a problem.

Ha, didn't noticed that Case replied before me. His advice makes sense too π, previously made memory-blocks should always be deleted. Else, the new block will be "guessed" by the interpolation algorithm. Forgot to mention with regards to P700 on the SMPS. Don't be blinded by the 69V adjustment procedure. Nowadays, we are watching HD (and higher). The way a lot of folks do is this: put your horizontal width at 95 with the remote and tweak the P700 pot till your screen is properly filled, at the highest resolution you will watch your movies. That simple.

Bandwidth wise, both BR909 and Cine 9 (CineMax) are identical (180 MHz). The software limitations found on Cine 9 (CineMax) are on the maximum horizontal and vertical scan frequencies. 132KHz horizontal (against 180KHz on BR909) and 210Hz vertical (against 240Hz on BR909). That was necessary to be able to make the fans run at lower speed. You can swap the controller, but I doubt it will behave differently. The trouble-free use of Oppo as a source, proofs that. I think is a timing issue from your Radiance scaler. As I don't have any personal experience with Radiance scalers, i can't comment too much but what Kurt is saying makes sense.

For sale two extender boards, 2 rows 64 pin DIN 41612 eurocard connectors. One with extraction hinges, one without. Not suitable for Barco projectors, but for some NEC. 50β¬/piece, shipping not included.

Oh, this is bad news Case. I really don't find the right words to express myself, but we are with both of you in this fight.

Hi Lars, Without extender boards, soldering a wire to pin 1 of J200 is the only option. Yes, we are talking about J200 on the SMPS sub-board (R763142S). Pin nr. 1 is the highest one, when the SMPS is mounted in the projector. Of course, the easiest way is to solder the wire on the backside of the PCB, like in this picture. Good luck.

Just to remind you guys, this iris interfaces won't fit the Cine 9/Max/BR909/SEOS919 machines. The camera is the same, but the interface not (different part nr. and lay-out). R763318 is needed.

I thought it was sorted out, but Keith just asked on the other forum about your board Case. I found out that this board is the ABL controller, meant to work with latest neckboards (with additional connector). They were needed in multiple projector configuration from sims and planetariums, to ensure the same level of black-level on all machines (network controlled). For single projector use, is beter to pull it out and use the standard ABL. In this spare parts list, we can see the board. BR909_spares_matrix__ref._TDE1320_03.pdf (10.38 KB)
