MOD: TV20E91LAV U16. N SERIES: AA002398 SEMP when I turn it off it says "TOSHIBA" the TV darkened a little, and it doesn't look clear how it looked in its original form, the darkness is constant when it turns on and when it is hot or on for a while it is equally constant .. !! that fault was produced due to the electrical dips or deficiencies that are constantly occurring in my city .. I hope your prompt help teacher. Thank you...
Of course, the electrical network is stable in the range of 110, 120 so there are no problems but I have already visually checked the filters and they are healthy, I also think they are the filters but I already checked the biggest ones 385v 220mf --- 160v 220mf - --160v 33mf the others are small or what do you say I change them to discard ??? Or is there a specific filter that usually produces that fault? I apologize for my ignorance about this branch (tv) but what I stand out most is in the electronics of the audio car and everything is empirically ... I hope your prompt help teacher.
Hello teacher! good evening! I already did the test by raising the brightness on the flyback (screen) and it improved for a few seconds and it got darker than it was but it worsened more haha .. what other step would you take to repair that damage .. it really seemed like it was a filter but as I said the filters are healthy in sight they are fine, what would you recommend .. ??? I hope and continue helping me to solve that fault !! I hope your prompt response thanks ..
Prof is probably the fault because I have seen several tutorials that change only that filter or ceramic capacitor, teacher I tell you have a yellow ceramic capacitor 102 LSK which would be the replacement of that capacitor? I saw that they placed the same blue one but I don't know the value of it! because I also saw that they extracted it and voila! Can it be possible to extract it and not place anything? or should we replace ??? What would be the replacement of 102 LSK yellow ceramic capacitor?
yes teacher that was the fault the ceramic capacitor! repaired thank you for your help (teacher)
