Question about Televison & Video
My RCS F38310 is out of fucus, bright and large picture with white lines running across the screen. Is anyone else having the same problem? What can be the problem? What needs to be done to repair the TV?
This sounds like the Extremely High Tension (EHT or high voltage) is too high. This is supplied to the cathode-ray-tube via the sucker-like terminal clipped to the side of the CRT as in all conventional tube TV's There is an adjuster but to set it correctly requires a voltmeter that goes up to 30,000 volts or more. The chances are that the regulation of the power supply has gone wrong. One other thing, not wanting to alarm you, if the EHT really is too high then the TV will be producing more X-ray emission but it will be a only be a small amount more. The EHT needs setting properly to bring the emissions within acceptable limits not to mention making the tube last longer in this well-praised set. Try not to use the TV as there is a possibility of eventual damage the tube or other components. Please seek a professional repair service. Although this reply is not a complete solution, I hope it will help you decide the way forward to get your set working impressively again. Good luck.
