| Posted: Fri Apr 11, 2014 6:55 am Post subject: I've successfully experienced 3d with barco 1209/2,wonderful |
|
|
In recent weeks,I've been keeping doing modification in my barco 1209/2(HD-120 lenses). The focus H shif, RGB switcher board,G2 board, SMSP board have been modified, I've changed many old capacitors with new,eliminate harmonic frequency and noise from power part,expand input stage BW to make sure at least 1G in the video path before neck board(neck board modification is underway,I want it with at least 200M from original 120M),by the way,the quadrupler is repaired,the performance is even better than new one cause original barco quadrupler is not good(the working votage for capasitor used in original one is close to the its maximum resistance limits,so why quadrupler is often broken or damaged,you can replace it with high resistant capacitor to improve performance to get high focus voltage).
after above modification,the performance of 1209/2 is improved a lot,it has pretty much more fine picture,more pure color and detail,deep image,the focus,the brihtness and contrast all have better performance than before.
so I tried 3D, bought 3D fury and pair of emitter and glass, it is working!
the output format from panasonic BDT300 is 720p/120hz,the picture is amazing.
it is bright,very bright, actually when i watch 2d movie,the brightness is set on 35,the contrast is 56 to meet the super hivi cast requirement, but when watch 3D movie, i need to turn brightness to 40 and contrast to 65 to get same bright picture after wearing a active shutter glass, by the way,my screen is dalite high power with 2.8 gain,123 inch 16:9.
3D picture is stable and vivid,the most important thing is it is bright!
I love my barco 1209/2, I expect after modification of neck boards, it will keep improving.

Wow, you replaced the caps in the quad with beter ones ? Congrats, AFAIK you are the first one. Some people already tried to open a quad in the past, but seems not to be easy. If those are to be fixed and even improved, a lot of CRT users will be glad.
Do you have some pics of that process ?

ok,actually the quadrupler is repaired by my friend, as you know, the quadrupler is big problem for barco projector, it really pulzzed us during past years until mid summer of 2013.
My friend detached quadrupler and did anasylsis of its structure and damage cause, he found out barco quadrupler is 7 multivoltage, there are 7 multvoltage capacitors in quadrupler, 6 are double-voltage except the first one, output voltage is 34700V, divide 7 and multiple 2, each capacitor bear 9914.2V,but real situation is actual voltage is a little bit higher,the front will bear more higher voltage than rear ones, that is why front capacitor always broke first.
if the first broke, then the rest will share the tatol voltage, the rest capacitors break one by one as time lapse,that is cause barco quadrupler is prone to be damaged,maybe there is a explanation,to damage the quadrupler for protecting electron gun if problem happened,anyway, quadrupler of barco is weak parts.
Now it can be fixed, you should find high bearing multi-voltage capacitors(recommened 20000V bearing capacity),and arrange that in to original case, remember making sure no more than 5000V between two capacitor to meet demand of isolation of 704 silicone grease.
after finish this job. you will get best quadrupler to enjoy your HT, never warry about your quadrupler.

You might have to get your mate to do a few of these for sale, i have two here that are abit iffy.

If you were in China, it is very easy ,just send your quadrupler to my friend to repair.
He already fixed couples, and all now are working fine,no more damage capatitor happen.
To maunfacture new one is hard cause it is very difficult to find good high-voltage transfomes(1:15),self-made is not reconmended,silicon irons and transfomre is not proned to be damaged like multi-voltage capacitors,so we just use original case,transfomer and silicon irons, only capa need to be replaced.
new replaced capa with high bearing ability, it is very hard to break, good quadrupler make best focus and brightness even watch 3D movie it can output stable high voltage to eletron gun.

Might have to send these buggered ones to you at some point and see what you can do, i imagine i wont be the only one willing to pay you for this.

Wow man this is awesome! Do I understand correct that this quadrupler is filled with the white silicon kit? They used to use oil bads with high voltages. Very important to keep the unit from sparking into the air.
Thanks for the pictures!

the white one is silicon grease to isolate high voltage enclosed from leaking.
barco original quadrupler is not good cause inside multi-voltage capas bearing 10000V which almost equal to its maximum bearing limit when thay are working , it is not strange if it is damaged.
If you use bigger bearing ability capas such as 20000V, the volume of capas are bigger accordingly,so it is very important to arrange these capas in original frame .
To use 704 silicon grease fill and cover, remember do not use too much one time since it will never dry if it is too thick.

That's true. However, before now I suspect many dead quadruplers were simply discarded, since they were considered unrepairable.

|

i am from germany and my english is not so good.
We have a Barco 808s with a defect quadrupler. Now i want to repair this with the tutorial from this side. Can you please write me, whitch parts you have build in?
My diodes in the quadrupler just have a red point on the wire. Can you tell me, if it is the Kathode or the Anode
Greetings

I also have a further question, i have a quad here with "blury, no focus" written on it, will that have failed in a simular way?

Hi anthonywong123
I've already written once. Unfortunately I can not find any film capacitors in the network. Can you please write me which capacitors you have installed and where to buy?
regards

Sorry,Hunner.
it is not me but my friend to repair the quadrupler, i just translate what he said in his original post in chinese CRT forum,I don not know the technical know how ,sorry i can not do any help about it.
