21 "slim lg TV model 21FU1RL does not turn on
It turns out that I placed the d1877 transistor and turned it on but it warmed up in 30 seconds, I checked the filters but I didn't find any broken ones, these are porcelain as I can check the
The TSH has a good decipator ... look at that ... it should have a large size decipator ... and the tsh well attached to the decipator ... if the TSH overheats so fast ... it may have some overload on the stage hor, .. when you turn on the tv it looks good on the whole screen ... it looks widened in the hor sense, ... the + b stays at 110v when giving power ... check or measure the diodes that are between the TSH manifold and ground and see if they are not leaking ... if it is the CW81B chassis the C414 and 417 must be polyester ... see if they are the originals ... mention chassis number ... try with the D1887 without damper.
Hi friends thanks for your input but it turns out that I had a c414 capacitor that mediates well but at the time of working this presented a leak replace it and the TV worked perfect
Hello colleague: I'm glad that the TV is already working ... the prob, I had it in C414 as I suggested in my first comment ... do not forget to value my contributions as a solution ... this way it remains in the solutions file for other colleagues ... "congratulations" on the achievement ... until another opportunity .... greetings!
Hello colleague Victor ... excuse me, the colleague has given me the solution ... you are right ... it was up to you the solution ... if there is a way to change the solution there are no problems colleague ... Tell me how I have to do it ... that usually happens ... and it has happened to me too ... Anyway I leave you a like since, you deserve it not only x the wrong solution but also good x partner ... I hope you know sorry for this mistake ... regards!
