good evening friends, I ask this question for a problem I have with a slim tonomac of 29 since they gave it to me and I gave myself to the hard work of repairing it since it was totally reheated broken filters ic damaged vertically throughout its stage fast diodes and associated resistors, coil and capacitor polyester 300nj x 400v burned faulty yoke dry filters, 180v magnification and so on, now what I started but after a few minutes of working the TV is as out of focus the image is very barely in the background, then I have to turn on and off several times until the image returns but after a while the same thing happens again. If someone could help me I leave an image attached. From already thank you very much

Good night: The fault on the screen in my opinion seems to show one of the classic failures due to the absence of one of the supply voltages of the vertical stage (- 14V) and therefore the vertical IC is in poor condition ... Always If you have this fault, it is also advisable to sweep with all the electrolytes of this stage ... You should clarify to check the diodes ... The fuse resistors of the voltages less and more than 14 volts.

I think you check the filter takes the vertical oscillation of the jungle to the vertical to me this happened to me and it was the dry filter

Hi Dylan723, the problem could be the socket of the Tube. Sometimes the Focus voltage connection is sulfated. Change it to see what happens and comment the result. Best regards

Hello Dylan723 open this link and study these two cases (when you see a case there you redirect to another) related to your fault, it is better that you explain everything if they serve you value, greetings ------

[b] that is a typical vertical fault, here in the forum it was treated many times. Generally it is how much the integrated vertical output fails or one of the 2 voltages with which it is fed is missing. It should not have much time on the tv with that fault, it will take an unpleasant surprise. greetings [/b]

Friends I apologize for the delay. I already managed to solve the problem of this tv. I changed the vertical integrated and the image returned but with cushion effect what I did was change the integrated width together with the nj300 coil and the 6.8uf non-polarized capacitor I thank you all infinitely for your valuable time
