Hello good night friends of yoreparo, I get a noblex TV of 29``, the TV turns on the standby light but it does not start it is as if it were protected, it already changes the horizontal transistor and it is the same, check the main source and the voltages are fine, check the secondary part of the source and also pass all the tensions, replace filters and resistors around the flayback and horizontal and still protect ... Reading in other forums I saw that I could do a test disconnecting the yoke to rule out that the yoke is failing, I did it and it is still protecting. It may be that the flayback you are wearing is failing (It has a bsc29-2699s) It may be that fault or it may have some other fault. From already thank you very much
