Screen Issues


Grounding problem. Sometimes too much, sometimes too little, grounding is a hard one to wrestle to the ground. Due to the possibility of ground loops, too much grounding can be as bad as too little.

Try unhooking all your components and see which one causes this thing to happen when it's HU'd.

The most common offender is having cable hooked up, whose grounding can cause this phenom and also grounding hum in the audio. You can get an isolating filter for cable grounding that allows the cable signal to get thru without allowing the grounds to connect to each other. This usually solves the problem.

Black horizontal lines


Sounds as if you have a bad capacitor in the horizontal deflection or video circuitry. You can spot a bad capacitor in circuit with a ESR meter.Hope this helps.

The Samsung has bad convergence IC's most likly. This should be repair ONLY by a trained technician as a TV set is not a place to experiment or tinker with because of the extremly high voltage inside. This repair should cost you in the range of 250 to 400 bucks . Good Luck
