cyberlux tv chassis -PH08KX-N22 yoke cables problem
excellent your explanation followed what you told me thank you friend ... and the TV turns on but gives me scratches and the screen looks colorful you can hear perfectly you can barely see the menu when I turn it up and low volume you can see the bars that will this fault be I think it's the vertical you think friend?
hello: if the screen is full in hor direction, and vertically we discard that x now ... if you have lines on the screen there can be several causes ... you should measure what tension you have in the cathodes of the tube ... they must be even (approx) 150v ... change the C569 from 22mfx250v ... the colors on the screen, set the PTC to work ... measure the ABL on pin9 of the fli-bak ... deven haver about 7v ... change the C161a-C564-C558-C453- all x the same values in mf and voltages q, the originals of the tv ... the C567 of 220mfx160 change it for a new one ... the screen voltage decreases a little ...
friend perform a test moved the scriin to see if the stripes disappeared when they saw that they did not disappear moved the focus turns out that the TV turned off then turned on again and the moment of turning the flayback bulbs the tv turned off turned it on again and the r917 commented to smoke r936 and r937 the same .. I measured them and they are in good condition but now I have no idea where to check ... I need your help friend
hello: it is rare that, when moving the screen or focus, the video transistors are damaged ... if smoke comes out of those resistors, some of the transistors in the socket of the camera will have been put short ... now you will have to , measure one x one all the transistors q, are in the socket of the tube and see if there are some in short ... remove the platelet from the tube and make the measurements ... measure the zener VD361 on the plate and see if it is not in short ... if you need the scheme I embed it ... well there are npn and pnp transistors in that socket ...
if you are right brother ... if you can send me the diagram ... nicomena2015 thanks for your support at your discretion where this fault could be? .
something happened q, those resistors will smoke ... as I explained, I must have some comp, shortly in the socket of the tube ... you must measure everything ... measure the VD558 q, it comes out of pin 10 of the fli-bak and see if it is not short ... the zener VD361..all what, explain more arriva ... do not turn on the TV until you find the short..ok..giate of the scheme q, I embry x mediafire .. okay..

that R380 goes to the pin47 blkin of the micro N301 ... if it is burned, the micro q enters, it comes from the AKB of the socket of the tube ... and it may have shorted the micro ... remove the R380 but in my opinion it could damage the micro ... if you are going to continue testing I suggest you put a 150w lamp between the electric network and the TV so that it serves as protection x if the short film continues ...
well I'm going to withdraw it and I will continue looking for the short one when having news I comment thanks friend
hello mate check the components of the socket and I got nothing damaged I just have to change the resistance r380 ...
