You can use any transistor of 1500 volts for 8 amps with damper diode ... I usually only because they come in good quality in my locality I use as a replacement of 8 amp transistors to the J6810D (It has to end in D)

companion these TSH are with damper, and if the size does not matter, you can try anyway it will not cause damage to any circuit, luck.

It would be useful to mention, Brand, Model or chassis of the device you are seeing. in principle the D2449 is much less amp than the transistor that mentions BU4508DX ...

If you instantly burn the TSH, it is because there are other components in poor condition; It may be that the same fly-back is in poor condition, or components associated with the horizontal output transistor.

According to the chassis diagram that mentions the selected horizontal transistor, it is the correct one, unless you are using one of doubtful origin, of poor quality, it may be the cauda, the counterfeit transistors do not hold a single second, they cannot turn on a TV. ... I use the 2SD1881 for 29-inch televisions, I don't know how many inches and the type of tube it is, this will depend on the + B ... In the diagram it says 140 volts, but I don't really see it well as must be.

In addition, the TSH does not disappear just like that, if it did not bring it, it is clearly because they already intervened the TV, in some of those they did not understand the reason why the horizontal transistor is destroyed. In these cases, I call the client and interrogate him to see what additional clues they give me, and well if they tell him nobody touched him, what can be done, they always lie, they believe that they will be charged more for that reason.

The TV is 21 inch flat screen and because I do not have the diagram I did not know that TSH used pr and qm dises that that serves him because boy to look for another possible fault I just have to discard the flyback because I test the condensers that are in the horizontal stage and they are ok ahh what I forget to mention was that when I try to turn on, the high voltage pr is heard perfectly in second, the relay is heard that is activated and deactivated and if I disconnect it at that moment the TSH D2499 burns me and change the capacitor 25v 47mf q is the transmit 60HZ or .9V q arrive at the base of the TSH pr the continuous fault

the horizontal frequency is 15750 hz in ntsc, and 15625 hz in pal-n.50 0 60 hz is the vertical frequency.

The TSH 2SD 2499 is 6 Amp. while the BU 4508 DX is 8 Amp. However, FLY BACK is probably burning you.
