Your TV could be picking up electrical discharge from an old appliance. Try removing the secondary ground by installing a 3 prong to 2 prong adapter, or just pulling it out with pliers. Common problem with HD sets.

If the lines are verticle,it could be a bad control board/data ribbon that connects to pdp panel. if they are horizontal lines,it could be the y boards (main for power, buffer upper and lower control half of the panel each) if not,replace swollen capacitors on the power board.

Veritcal yellow line on 50" sceptre tv


The edge ribbon connector may not be connecting (on the inside of the tv). Cure is foam strips between screen edge connecters and inside cover. Or, Memory chip (used to make the picture appear), may be bad. All flat panel tv's use a memory chip to make picture appear (it is digital after all). And if memory chips are bad, picture will have lines, jags etc. But it sounds like you have edge connecter problems. Place foam between inside cover and screen. TV may have been thrown around in shipment, and edge connecters came undone. They're very lightly soldered on some sets.

Horizontal lines shadowed / blured picture after 20-30 minutes


There are some semiconductors or capacitors that are leaky. Might need thorough check up inside the TV.

White lines across tv screen


Without seeing the lines I can't be sure what your set has wrong, but here are a some possibilities:

If the lines are lines are confined to the top inch or two of the screen and the picture looks otherwise normal, the trouble is bad capacitors in the vertical output circuit. Fixable by replacing the bad parts.

If diagonal lines are across the entire face of the picture tube and the picture looks washed out, the trouble is often a bad capacitor on the 200-volt line to the picture tube. This may be on the main circuit board near the horizontal output transformer, or on the small circuit board plugged onto the end of the picture tube. Again, replacing the bad capacitor can fix this.

If your TV is actually an RCA, someone may have bumped a rear-panel adjustment. On the back of the TV near the bottom right are two small knobs. RCA left these adjustments exposed inside of putting them inside the set like other manufacturers. These sometimes get bumped if someone was behind the set cleaning, or if a pet got back there and hit them with a tail. The top knob adjusts focus, and the bottom knob adjusts something called G2 or screen voltage. If this gets turned up too high it can cause the faded picture and diagonal white lines. Turn the adjustment down until a black screen looks black instead of gray.

A bad picture tube or horizontal output transformer can also cause lines through the picture. If this is the case with your set, it's time for a new TV. The transformer is relatively inexpensive but labor costs aren't, and the repair bill may exceed $200. If the tube is bad, there's no point even considering repair. The tube cost alone exceeds the cost of new TV.

Hopefully your lines are easy and cheap to fix. Good luck, and thanks for using Fixya!

I have a Sony tv (32v-s15) and the picture was slow to appear (even though the volumn was fine) so I turned it off, then on again, and it worked. The next time I tried to turn it on, the whole thing just...


Your TV has something shorted inside, and is not a direct short. If it was a direct short, the fuse have been blown. Through my experience I advise you to replace the Picture Tube base socket, which can be located at the picture tube base card. Some CRT base cards will poise this type of problem. as their contacts will worn out with time.

Turn on pic turns red with thin bright red horizontal lines


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.

Horiznal line across screen


The picture tube itself is not longer being manufactured and the replacement might exceed the price of a new TV.
The vertical line you see on the picture tube is not a failure with the picture tube but a different part inside the circuitry.
