Overheating and breakage of the Q504 transistor type 2SB698 leads to an avalanche-like increase in voltage at the output of the pulse power supply. It is recommended to immediately replace this transistor with a more powerful one and one with the same pinout, for example, with 2SB1010, even if when checking the Q504 transistor it seems to be in good working order. When repairing Funai TVs, you should also replace the electrolytic capacitor in the timing circuit with a new one of the same rating.
