Question about Televison & Video
I checked AC cord, Fuse, Rectifiers, Capacitors, Resistors etc. in the power supply stage. Everything is OK. I replaced SMPS control IC (TEA1506P) and Transistor (K2645).
Sounds like SMPS transformer is faulty. If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

There should be a small valued cap in the primary side (22ufd?) at 250V. Check that. Also, look for other small caps int he range of 2.2ufd with 200V ratings in the same general area.

There should be circuit designations printed on the PC board. Without those, there are too many possibilities to give you anything useful. Can you provide those please?
