Re: tv beginning to flash green with horizontal white...
From your description it sounds like a bad picture tube. The lines are called retrace lines. There is a small chance that a component on the small board that connects to the neck of the tube may be bad. Without model number information it is very difficult so say further. Some picture tubes can be re-jeuvenated with the appropriate machine ( at a TV repar shop)
If you feel adventurous and are careful you might try GENTLY tapping the neck of the tube and see if picture improves/goes out. If the tapping does change the picture it is definitely the tube

These horizontal lines are vertical flyback lines and would indicate
one or more of the tubes cathode drive circuits are defective.
As the picture is predominantly yellow this would indicate excessive drive to red and green guns. Check the red and green video output stages especialy any clamping diodes.regards from Vintie
My Loewe Aconda 81 HDR TV will not turn on. When I press the power button the green light comes on but the red light stays on with it and after a few seconds the green light goes out and the red light stays on. Any help please.
check the supply at horizontal driver trans former ,if voltage is correct at ho/driver trasistor ...then check allthe fusible resistances from power supply,,,if tv is taking h/oscillation for awhile ,,give more screen control in lot,,, & see for a horizontal line ,,,before tv becomes off,,, if so vertical ic problem...
Any operation outside normal parameters would be considered "broken". Most broken TVs are repairable by a competent servicer for less than the price of a new one. A symptom like this however is the exception to the rule. It may very well be not cost-effective to repair. This is why most repair shops charge a bench fee for evaluation. If it is worth the peace of mind to know for sure then the investment of the minimum fee would be necessary.
Sorry to say, but that's usually the sign of a bad picture tube. One of the elements inside the tube shorts and you see the picture you describe, and the set shuts down due to high voltages getting to places it shouldn't. There's no solution except picture tube replacement, and that is uneconomical. You're better off replacing the TV when the tube goes bad.
you have a shorted green CRT that is affecting the other crts the short is internat to the crt that leaves what is called retrace lines. if the set is more than three years old then replace all three guns.
