Daewoo TV chassis cn-oo1n vertical failure
Already. Solution I made the filter change that is close to the 1000UF / 25v flay and now the full screen now looks dark and has a voltage of 4.2v filament.
Correct amig jhonn between setting the menu and they are well rises and low contrast and brightness but it does not clarify and the colors if they are well written is in 355v and I add it to more than 400 and the difference is not much the same it looks dark
Well I will continue tomorrow on the writing if you graduate goes up and down the osd looks good connect dvd and looks the same image the filter c411 on my tv is 10UF / 50v not 250v as the colleague says pin 18 junga has 8v and igua change the c411 and still the same I need to measure cathode voltaj and review the r412 will be tomorrow colleague
he is right ... I did not notice well ... I was referring to the C410 of 10mfx250v .. that is the q, filters the 190v for the amplifs, video ... measures the ABL in pin 13 of the jungle ... should haver 3.9 v ... measure on pin 8 of the fli-bak q, voltage do you have ... control the line of the 5v q, leave (l401) .. kia7805..va to pin8 and 43 of the jungle ... in the outputs of the pins 19-20-21-deven haver an average of 2.5v q, go to the amplif, video ... and in the cathodes of the tube you can walk in the 150v ... in C415 deven haver 10, 5v .. pin4 output of fli-bak ... try welding a R of 1ohm in parallel with R412 and see if it clears up the image
Good morning colleagues ice the suggestion of the friend nicomena change the c410 staying the same pin 13 jungle has 3.9v pin 8 of the flay h and 8.2v the 5v of the l401 are stable on pin 8 and 43, the pine 19 = 2.6v 20 = 2.8 21 = 2.6v and in the cathodes of the tube in R 110v G190v B114v and in pin 4 flay there are 9.9v the same in the c415. I have the script in 500v.
Now on the r412 placed a d 1ohm in parallel and the image brightened more and the cathode G q was in 190v low to 120v but the image has as a minimum vibrating stripes around people as sawtooth type is not stable. Greeting
well buddy: 190v in one of the cathodes is almost the same voltage of video feed ... it is evident that there is almost no emission in that cathode ... and maybe it is deficient in the other cathodes ... is somewhat depleted that tube ... with this reactivation you will throw another time ... that of the rallitas in the contour of the figures try to change the C410 of 10mfx250v .. or try from the c, remote to remove some sharpness .. .You lower the screen a bit ... lower the contrast a little ... see if with some of these options there are improvements ... don't forget to rate or rate my contributions colleague..healthy !!
Nomenomena colleague had already changed c410 changed again and nothing under the sharp contrast and nothing like the image as vibrant as the osd
it may be a lack of filtering in some capacitor in source or in the fli-bak ... change the C415 of 1000mfx25v at the output of the fli-bak-pin4 ... the C814 of 100mfx160v ... the C815 of 10mfx100v ... see if x A / V or video does the same with dvd ...
Friend nicomena and the c410 already changed it doa vece and it remained the same but with the resistance 1ohm in parallel with the r412 I already clarify the screen a bit more but follow the image as with transparent stripes type like sawtooth and the osd menu is not stable vibrant does not distinguish well
Ok coleg I will change those filters and if with dvd it looks the same example if h and a post or something in the background image does not look straight but zic zac type
Coleg niconema20 ok replace filter c845 d 10mfx100v and cash the bug was fixed friend send the best solution to close the post I thank everyone for their very accurate and effective contributions I will continue publishing failure for your prompt help of all
More specific is in the secondary of the choper on the line leaving + 45v there goes the c845 of 10ufx100v that was the problem with the image now if it is clear colleg greetings and thanks for the contributions
C 845 is not even in the list of components unless I see wrong.
Nor do I read where the colleague Nico whom I salu2 tells you to change C845.
That figure as C 815. And if it goes where you say. Polarize the 45v to the H driver and to the 33v of the tuner.
Correct friend Luis and colleagues, the chassis is CN-001N and in the diagram I see c815 but on the TV board it appears to me c845 it must be a die error run x the confusion on the TV appears like this and that filter the fault it presents is that the image looks vibrant as zic zac does not look standard and also the osd on tv and on dvd, regarding the dark ise as colleague nicomena20 told me on r412 place one of 1ohm in parallel and I clarify the image being well and It is on trial.
Hi Romulus. You always have to change ALL vertical circuit filters from their power supply. It will give you security and guarantee.
Dark image. In this case you do not comment if you entered the user menu and increase contrast and brightness and if they regulate the same well. If these are OK, measure the scrin voltage that should be more or less above 350v. Do you have a good definition of colors?
Correct amig jhonn between setting the menu and they are well rises and low contrast and brightness but does not clarify.
When you move them you notice change or not in the image. Put the TV in AV mode then adjust the SCRIN until delay lines come out and slow down until they appear. So leave the scrin regulated. if the change of C indicated by the colleague does not improve. Control R 412. Or pin a smaller girl or a bridge.
Focus on the 190v that has the green cathode. KG
Maybe I got a good image by having green. You should control printed welds and components that work with green. Do this and comment on you and other colleagues at the bottom of the topic. But everything is confused.
I will remember this subject when I have a dark image (which I think there is seen that you say bright) and with 190v in green cathode. I'll just have to change the C 845.
