Case, do You know which models share quads and Splitters with the Max ? Im not sure on part numbers mate no, Hulio will know that bit. Quadrupler R763368 is BR909/Cine 9/Cine Max specific, regarding the part number. You won't find it in other projectors. However, some people reported good results with other so called "new style" quads ( without the focus lead ), saying that Barco changed the part nr. just from a comercial point of view ( they could charge more ). The splitter R762718 is to be found in Cine 8 and 808S series too, but they are all pretty interchangeble. Take care you use one with that fusible resistor on the mini-board. Old splitters don't have that. Switcher board R7627195 is shared with Cine 8 only but, like Redfox said, the one from 1209S will work too. The daughter-board of the power factor corrector R7631452S is shared with Cine 8 equipped with PFC too, along with the communication interfaces in front and back of the projector. That's all, relevant CineMax spareparts are not used by other projectors. I know is frustrating with a non working PJ but it's a hobby and when it will be running, because YOU made that happened, the satisfaction is huge. So don't give up. For now, try what Case sugested to rule out a broken switch card. When and if you are sure is broken, i can send you a working spare-one if you wish. You can try it, free of charge, and if it works and you decide to keep it, we'll make a deal. Else, just send it back to me. I hink i have a RGB to DB9 cable too, for port 3. We still don't know where you are located.

Tjeerd, i never said PFC board. Just PFC sub-board, the small doughter-board of the PFC.

I also know my switcher was used in a cine 8 because I bought it from fragzero with all kind of cine 8 parts. True, but the switcher in Cine 8 is not the same as in 808(S) series. It is in fact a specific Cine 9 switcher ( R7627195 ). Along with that, Cine 8 and Cine 9 share the following identical parts ( different than those in 808S ): EHT- 7627165 Splitter - R762718 ( also present in 808S ) PFC sub-board - R7631452S (only Cine 8's equiped with power factor correction) Front input board - R7631295 LimoPro - R763315 Aside, Fragzero got that Cine 8 from me .

The core of those coils is made of ferrite and the strong magnetic fields will make a metal screwdriver glow red in few seconds. Use of a plastic/wood/ceramic tool is needed. Normaly yes, we don't need to bother with them because they are factory adjusted. That's why, they are not mensioned in the installation manual, with exception of when we change a tube. While projecting a pattern on the highest resolution you will use, turn the core on all three coils all the way in ( downwards to mainboard ). The smallest raster width should be use as reference. Turn the core of the other two colors back out to match the smallest. Look at the horizontal centerline to be able to tweak with precision. Again, it is important that one of the coils is turned all the way in, to avoid running out of max. horizontal width. Each time we touch the 17V / 48V rails or change a tube, we should in fact recheck the raster width coils.

Allright Case, thanks for the info. No hurry regarding those jumpers, i can't work further at the moment anyway... I will flash the controller too than. Cheers.

I am in a process of moding the fan circuit on my BR909. The scope is to duplicate the one from Cine 9. I got a hold on those ultra rare speed- regulating boards R763706 and the metal work is in progress ( noise baffles on back-fans and in tubes-compartment. Cine 9 has a soft. limitation of the max. upper frequency, some think in order to be able to run the fans at lower speed, others think it was pure to eliminate some video noise. So not sure if i should flash the controller with Cine 9 V2.21 or let the existing BR909 V3.11. People reported swapping their broken controller on Cine 9/Max with BR909 one, while keeping the same noise level as before. Will take some pics when ready.

Hello Case,
Nice to hear you could flash the soft. Do you mind sharing a walk-trough kind off ( while PJ on stand by or on, at wich baudrate, W3 jumper bridged or not, how long it takes etc ) ? Also, what kind of extra features does the new soft offers ? They could be LiMo Pro related ( immage processing or so )... Right now, i'm in a process of replicating the Cine 9 fan circuit on my BR909. I have the speed regulation boards and the metal work for all baffles is in progress. Not sure if the soft has to be Cine 9 specific, that's why the question about the extra features. My BR909 has soft version 3.11 so maybe flashing to 2.21 will be a downgrade ?? When you have the chance to open your Cinemax next time, will you check the position of few jumpers for me please ? On Cine 9 schematics, i see some non logical things. Could be a mistake.. Jumper S1 on those two speed-regulating boards R763706 ( front - rear ) Jumper S1 on focus board R7631395 ( +fan - +12V ) Jumper S86 on horiz. fan control R763452 ( on frame - in conv. ) Thanks. Almost forgot: why you didn't flashed with V 2.22 ?
Cheers

Yes, ESR meter gives a more accurate way to test caps. With a multimeter, the chances are big you'll test a realy bad cap as good. However, the test must be done out of the circuit ( caps desoldered ).

Thanks. @ Casse: Do you have another horizontal deflection board to try ? ( R763140 ). It is the hotest card in the system and from temperature differences, solder points get loose very often.
