Good morning I have a Toshiba TV in my workshop that came with the failure that only a horizontal line was seen on the screen when reviewing the integrated La7837 was shortly replaced by an equal one and then connected to power socket and everything worked well after three days it presents an image failure, the screen appears the cushion type box and I have already reviewed some components but I still have not been able to find the damaged part that can present this fault, from first hand thanks for your knowledge that are of great help for me as a beginner in this field of electronics, please if you have anything to help I am waiting ...

Good afternoon I changed only the 35v x 470uf that was the one that was broken but if the TV turns on well only that the side sides appear with that type of fault, ah also yesterday I turned it on for a while and the image bone the screen was getting opaque until it went dark and today I turned it on again and again there would be a nolmar screen but with the cushion failure and after about 15 minutes it went dark again I have not uncovered it again to check because I am in other things, but in what uncover and check I tell you anyway any contribution is important ... thanks my friends
