Sounds like you have a shorted green gun in the CRT. It may also be the green drive transistor. Check the trans first, and if the trans is good you will need a new CRT

Our three year ol Samsung TV has dark horizontal lines across the top of bottom of the screen. It is getting worse


Welcome to fixYa!

When you see lines like these across your LCD, it indicates a problem with your monitor's electrolytic capacitors.A faulty filter capacitor in the power supply board (SMPS board) can cause horizontal lines across your monitor screen.Horizontal screen lines are one of the most visible problems I see in LCD monitors & TV's that are 3-7 years old. It can happen as much from heat, humidity & less-than-ideal operating conditions, as it can from fluctuating current supply or manufacturing defects.

The way to repair horizontal screen lines is by removing the capacitors from the printed circuit board (PCB) and testing them with a LCR meter.

If it shows zero, there's your confirmation that the specific capacitor needs to be replaced.

now if you can replace them your welcome but i wont suggest that , cause you may break it more....!

any ways do comment if it helped you in any manner!

Green lines across the screen


The green CRT is drawing to much current, could be bad, or you might be able to turn the screen voltage down, that is on the focus block.

No clue


Sounds like failures of the convergence output IC's. They should be STK392-110's in the set. Also check associated circuitry around them.
