If I understand you correctly:
The horizontal output transistor in your TV blew.
You replaced it with a BU2520DF.
I'm not sure what you mean by "change to dynamic mode".
Usually, horizontal problems in TVs are caused by bad capacitors in either the sync circuit, the driver circuit, the geometry circuit or the output circuit.
When I repsir problems like this I use an oscilliscope to find which stage is not working properly, then start substituting the capacitors in that stage until the problem is solved.
Look for large orange or blue ceramic or polyprop capacitors with bulges or cracks in them.
Look for electrolytic capacitors with bulging tops or shrunk cases.
Check and make sure no resistors are brown, they may be blown.
Use an ohm meter to test low value resistors in circuit.
If you don't have an oscilliscopw, that's about all you can do.
