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?

Before replacing the STR, have you checked all the components related to it? When STR burns out some of the nearby components, such as zener diodes and other resistors will also get damaged. You just replace the components, especially, zener diodes, in case it does not show any fault, replace it. Connect a 100W filament type bulb in seris with the power supply, and switch on the set. This will reduce the power concumton at the begining, and we can check its heat effect also, after all are ok we can connect directly. Check the smoothing capacitor at the secondary 130VDC. Replace it also. If you need furthermore assistance, feel free to contact me through Fixya. I'm an Indian, residing at Trivandrum, the capital city of Kerala State.
