issue fixed, it was another bad splitter.
The third splitter fixed it.

Hi guys, Am back again and need valuable inout from the experts. After having the dreaded red led on the eht board, i switched out the quads and multiple eht boards. Only to find out it was the splitter, but now the whole image(RGB) is modulating in and out of focus, and totally went out of focus after thirty minutes. What should i look out for? the splitter or the focus board. I have tried a different quad , but it still persists. Hope to hear from the experts here. Cheers, swapped in a new focus board just now, the focus came back but still modulating. its like some kind of resistor failing causing the image to slightly go in and out of focus.

Ok , i finally got to use the lumagen to output a 1080p image. But it is very glitchy. I have two sources connected to the Lumagen, one an oppo Bd player and a sat dish dtv(1080i output only). The lumagen is somehow very sensitive to the hdmi syncing. I found out switching among the two inputs causes the Pj to go to scan fail, and sometimes the audio gets lost. It seems whenever the hdmi handshake sync is happening , the Pj goes into scan fail.There are times ,changing between inputs can cause a glitch on the Luma processor( as in a white noise image comes in). The clicking during the hdmi handshake causes the pj to sometimes shut off also.

after the factory reset remember to save it before you turn the unit off again, then try set the lumagen to output 1080P 60hz at all your different input resolutions, it might send out 1080P 24hz as defoult when feeding it 1080P 24hz. you need to set the output pr input resolution. I will try to check if it went back to its previous setting, i am going to tweak the pj again tomorrow. Million thanks for this

Also ditch the 720p res for now, that was the one the caused my issue, and i cant recall why. Yes( avoid 720), it seems i read somewhere in the past that you had an almost similar issue with scan fail . I am not near this pj now,but will be going back at it tomorrow. i will take all your advises and also not use Lumagen's second hdmi out( feeding audio receiver). The hdcp stripper has a seperate audio out anyways. Thanks for this , Case

Ok, factory reset of lumagen worked. It is outputting 720p now on both inputs. I also did Hulio's advice of turning up the width to 95 and reducing the p700 to fit the screen.
Now , i have to readjust the lumagen to output 1080p 60, On the first HDMi input , no scan fail.
Then, (on the Lumagen )after trying to have other inputs copy input 1's adjustments, Barco goes into scan fail.
It seems that switching between different inputs and resolutions on the Lumagen causes the barco to go to scan fail.
BUt, I had experienced that earlier with this PJ also, when switching between input 3(moome card) at 1080p and input 5 at 720p.The pj unit goes into scan fail also.
I can not seem to isolate the problem here.

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 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. Thanks again,Hulio. I was too focused on the p700 adjustments. This makes a lot of sense, i will try to readjust the amplitude. Cheers,

Yes it will be interesting to see if any stored faults show "COINCIDENCE ON", as this is what id guess to be the likely issue at this point. Ive seen it shut down HV on my Cine 9 before, and it was all easily fixed by deleting the one memory block that caused it. If you need to do a full set up, you should delete all the memory blocks anyway. There is no point starting from a previous setup that does not fit anything. Best way forward is to set all to mid point, then set the first block perfectly, then base everything else after that. The fact it goes away when you adjust a pot doesnt mean a lot to me, because by adjusting that, you throw the entire setup out the window. If i were to adjust that, id be setting the source to standard 720p timings and then filling the screen on 90-95 width, this way all sources should fill the screen easily enough. Million Thanks for this Case. Cheers,

Did you test that your radiance output the same as you input on a different display.? Be aware of the power supply to the lumagen might be bad if its a few years old, i have one here that works when connected to the tv, but not with the Marquee/ moome, and if you have HDCP issues you should be able to display the info screen and testpatterns from the radiance, just make sure your not feeding it HDCP protected content while you try that. The old XE should not need a HDCP stripper, so try remove that one as well And if you did not do it already its always a good idea to factory reset the radiance. Yes, sounds good.i will try doing the factory reset. Many thanks for the input. Cheers

HI Guys , hope someone here can put their valuable input to my problem. Seeking HUlio After changing to a Lumagen Radiance xe, i have been having scan fail issues. The red led lights up on both the smps board and the H deflection board. Have swapped out both the smps and H boards from a working cinemax with the same setup. This other set up uses the newer radiance 2020 processor, without any issues. Both systems has the HDCP stripper from viewhd. I found out that having an oppo player straight to the cinemax it does not go to scan fail. Meaning the PJ is perfect without the Lumagen xe. with this other PJ, the Lumagen seems to demand more h frequency lines . By the way i am also both using moome's latest barco 1.4 hdmi card. I also found out that decreasing raster width ,(P700 trimpot on the smps) solves the issue.I am now able to enjoy the Lumagen Xe and oppo combinaton for now. But am hating the fact that the screen size or the width is much smaller than before. and am also worried about having raster burns due to the smaller image. Basically this is just a temporary treatment on some hidden issues with in the PJ. am thinking of swapping the controller board from a 909. I think the cinemax controller board software has some bandwidth restrictions versus the 909s.

Hi Guys,
Am planning to readjust the P700 (at 69v ) for the hthd, looking at the service manual it only say pin 1 of j200. Problem is, it is at the bottom of the main smps board.Which means i have to solder a long wire to be able to use it as a test point. Am i reading it right? i mean is the test point at the smps board ? or the horizontal board?
Cheers,
Lars

Yeah it wont affect the focus board, if that failed it is just a coincidence. Ive seen HV issues cause bad focus just recently. Thanks guys.

Its not the focus board, its a HV issue. HI Case,
Always great to hear from you,
I have had HV issues before with two of my units. But have already replaced the quads and either splitter or eht on both units.
Anyway, I have swapped the focus board and this did solve the problem. I have maxed out the contrast earlier to rule out a failing quad. The high contrast usually causes the pj to shut down if the quad or other HV has issues.
Right now I am wondering if the 808 quad is causing the focus board to fail. Have been using cinemax for 8 years straight now , and never had a bad focus board. Always the smps and the quads.
