It's normal for new sets, especially Sonys to do that due to some sort of gas build-up in the new tube. My set still gets a high-pitched buzz after power on and lasts for a minute or two before silencing. If the hissing continues when the TV is turned off return it to the shop ASAP. It could be a problem with the power supply, something getting ready to blow up. Good luck

My SONY KV-XF21M80 produce a hissing (sparking) sound

That model number is not correct. What is an EHT? Must mean HVT High voltage transformer. If this set is 26 inch or smaller replace it. If larger yes replace the transformer.

You have your information incorrect, Q is not the designation for diodes, Q657 would be a transistor. First give us the correct number for the diode and how do you know it is shorted?

No sound, black & white picture

Invest in a good surge protecting power bar for your electronics such as TVs and Computers. This can save your devices from all kinds of surges and overloads.
