Hi BenigSevilla, these failures are caused by devalued components associated with the regulator, resistors, diodes and especially a 47uf-50v capacitor or close to that, also special attention to a low value resistance of less than one ohm that is 2W also associated to STR, correct the associated and the fault will disappear, just as a precaution also check capacitors and secondary diodes of the source, comment results
Good morning Antonio! I told you that by the time I got the vertical short, I checked those parts, I measured those components outside the board, I didn't find any outside their parameters, I also resolved the area, although I told you that welding is very good condition. Thank you for your contribution, my friend.
Good morning Dawer !!! I commented that at the time of getting the damaged components (main capacitor and the STR) I took out and measured most of the components of the source, and they were within their parameters, although I know that sometimes even while measuring well, they are damaged . I will check the source again, because certainly the one that turns off and there is not even the Standby on, should be a source problem, even a poor quality component (such as the STR that puts it again) Thank you for your contribution friend, I will be keeping the Both reviews and advances.
Good morning Evelio!
I tell you that I had the diagram, thank you brother. Look when I saw that he turned on the arm and cover it, then I realized the fault, I have not measured the voltages. I will uncover it, turn it on and wait for it to turn off and take voltage measurements and comment. ????????????
Remember that fan is not ethical bone is not recommended, you have to find the solution to the problem and leave it original since if the regulator is heated by some bad component and you have to look for the solution so that it is original
Anyway, if you work like that, you are respected, but here in Maracaibo, I try to leave original but not adapt and if I adapt, it is some compose but not a fan to a regulator or a horizontal transistor since the TV can come back
Friend have a test changing the main condenser, it happened once the STR was very hot to turn off the TV and the problem was caused by the bad main condenser
Good afternoon friends! I tell you that I already make sure and make sure that the problem is a non-original STR, of poor quality, I put an original one of a TV that is in use and it lasts 5 days working without the fan on. The trouble is that I do not get the original and put back the STR that I bought and left the fan. I explained that to the client and I am satisfied, the TV is working without major problem. Thanks for your comments.
