Check high voltage circuit on the power board for 390 volts or more at the capacitor. If the voltage is less than 390, change the capacitor. Use one 3X the current 100 uf 450 volts. I used a 350 uf at 400 volts (could not find a 450 volts at home). A bad capacitor will cause voltage to go from 375 volts to 380 volts.

It is the video card (most likely located at the center of the TV). A burned out resister (or if there is variable resister make adjustment) needs to be changed. If there is capacitors, check them too.

this sounds like a connection problem. are the scart or av leads ok whatever you are using ? if so then the most likely cause is the signal interface inside the tv. try connecting with a different connection system

Probably a faulty panel or not connected properly.
I would get it replaced.
