check the filters of the vertical stage or the diode that polarizes the vertical ic. tb can be cold welds. Comment results.

good afternoon companion, you must have a devalued filter in the vertical part, almost certainly, check them, if you do not have how to try them change them all, in your country I imagine they are cheap. and ready solved the problem, EYE, ONLY those of the vertical PART, should be like 5.

I have changed the filters and also the vertical. The TV improved a lot, but I have some fine lines of lag at the top of the screen. I have the diagram of this tv and according to the diagram the C558 = 50v x 470u and the tv has a C = 35vx47u installed, despite this I changed it as the diagram says and the lines are all via .gradesco more orientation .Thanks

Another thing when I give power the first thing that comes out when you turn on the TV are some thin lines of colors about 5cm apart from the top

companion you still have some damaged by there, either electrolytic or tantalum or ceramic as appropriate, check Ejm to make it easier for you, if the IC is 505, all capacitors that are number 500, belong to the part vertical, sometimes they are close, but sometimes they are a little far from the stage and that is why we hear that we are part of it, check and change, check cold welding. Cheers

I am with the colleague those 3 colored lines are generated by a capacitor as EL colleague says. Controls that well.
