This case is a case of damage caused by a lightning strike, causing the TV to display a blank white screen. Lightning-induced damage typically occurs in two ways: the power supply unit, software components such as the Micom, Chroma, or EPOMS ICs, and even the feedback path. Therefore, before judging what's damaged, conduct observations such as checking the condition of the fuse, measuring the transistors and power diodes, and components in the power unit. If the measurements are safe, the next step is to plug in the power cord and check the TV display. If it's blank, measure the voltage on the secondary unit, especially the VCC pin of the Chroma IC, as well as the 180V voltage and the output voltages from the Chroma IC, such as the vertical output and RGB output. If the vertical output and RGB output voltages are unstable or dropping, please watch the video tutorial below. Hopefully, this will be helpful.
