Hi


Thanks for using FixYa. To start with you'll have to open the back of the unit and check the connections to the main board and power supply unit. Usually this kind of issue is caused by a cable (LVDS) which connects from the LCD controller to the main board. You can try to unplug it and then plug it back if still its not resolved then you have to replace it. It can also be due to the inverter circuits for the backlights. The inverter is the power supply source for the backlights. There could also be a screen driver problem; if it is then you have to change the entire inverter board. All this is only recommended if you have some kind of expertise for checking the internal circuitry of the TV as these units have high voltages running even when the set is switched off. The cost to change the inverter board including labor would be around $250, if you get this done by a professional. Please do accept the solution if the issue is resolved or post a comment for further assistance.


Thanks
Rylee

SAMSUNG - UE40F6670 LED TV - I have thin black horizontal lines appearing in upper half of screen. They get lighter as the TV warms up but don't go away.


IMPORTANT: Horizontal lines on the screen are virtually NEVER caused by a bad T-con board. Horizontal lines indicate a defective LCD panel (screen). Check ribbon connectors coming from screen and the T-con board first but likely the Panel.

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.

Our LN40A630 has three horizontal white lines across the screen on power up (center, center of upper half , and center of lower half). After about five minutes the lines go away. Tried Picture Test in...


This is a sign of your LCD panel beginning to die. Sometime soon those lines won't fade away and will become permanent parts of your TV screen.

Considering the fact that your TV is approx 3-4 years old, this is normally the expected lifespan of a TV. Once the TV becomes unwatchable, your best bet would be to begin shopping for a new one.

Line thru screen


The LCD Panel must be replaced to fix both problems. The cost in doing this would exceed the value of the set. I recommend not putting the money into it.

Horizontal lines obstructing the second half of the ti 83 calculator screen, anyone know repair tips?


I had the same prob with vertical lines on the screen, and getting messed up when there was lots of numbers on the screen.

Solution: Change your batteries. Put some freshies in then adjust your contrast until you see the little black box. If you still have a problem with the lines, darken the screen until it's black (2nd up repeatedly) and let it sit for a couple minutes. Lighten your screen back to normal (2nd down) and turn off then turn her back on.

Green screen with almost horizontal zigzag lines


Is good that you hit it and it reacts,very likely you have loose conections in different places but for the distorted picture you need to check the horizontal driver transformer and flyback after that is corrected you need to check the complete chassis for loose conections.Take your time.Good luck.
