Hi

These sets are assembled using the wave soldering process and are known for having problems with cold solder connections. It is likely that either you have a problem with cold solder or failure of a resistor or integrated circuit which in turn is effecting the TVs capability to perform progressive scanning on the screen.

Failure of any of these electrical components can create the problem of horizontal lines on the screen.

It would be nice if I could tell you there was a quick fix or button to push that would fix the TV but that is not the case here. In order to identify the exact cause of the problem the TV will need to be properly examined with the correct electronic testing equipment such as an oscilloscope.

Hope this helps. Please remember to rate my answer. Many Thanks.

    Hi



    As stated In order to identify the exact cause of the problem the TV internal circuitry will need to be properly examined with the correct electronic testing equipment such as an oscilloscope.



    This TV has over 3,000 parts including millions of transistors inside the integrated circuits. Capacitors will change value, leak and become defective. Resistors will change value and burn.This problem can occur because of a fault being anywhere along the circuit.



    Vibrating the PCB is not a technical solution.



    I would advise that you have the appliance looked at by someone with the correct testing equipment and the expertise to identify exactly where the fault lies.



    Hope this helps. Thanks for using FixYa.

How do I fix my Sharp tv model LC-42D62U? On the tv screen now shows horizontal lines with repeating ghost images.


Hi Paul,
The horizontal lines on the screen are virtually NEVER caused by a bad T-con board. These horizontal lines indicate a defective LCD panel (screen). The Screen has small ICs that become defective overtime and that it isn't fixable unless replacing the entire screen.

Hi, possible causes for horizontal line on screen are,

Phone Screen problem and,
The flex of a phone.

When a screen displays horizontal lines on the screen, is when screen of the phone is getting damaged due to phone falling on the ground,or hitting phone on an object can cause horizontal line on a screen.
Solution to this problem is to replace the screen of the phone.



The flex of the phone can also cause horizontal lines on a screen. The flex is a thread like object inside the phone that makes the phone to function properly in terms of the display..

When the flex is getting damaged, it can cause such horizontal line on the screen display.

Solution for this problem,is to replace the flex.
Note : flex can be found only on slide phones.

How to fix horisontal lines on display ( see the picture)? They stronger when system is restarted and then fading but never disappearing. They always stay the same.


horizontal lines can be caused by either a faulty grapchics card or a faulty monitor. try adjusting the screen refresh rate. if you are using a windows xp system goto

start>control panel>display>settings>advanced>monitor

then adjust the screen refresh rate and see if the horizontal lines disappear. if not, then you probably have a faulty graphics card or monitor.

Horizontal Lines On Screen


horizontal lines = horizontal sync off . mitsbishi always seemed to have this problem .. on the older sets I would take the back off and inside deep on the board i would adjust a pot and sync it right .... and never had a recall, maybe your newer model has this too .. this little control,

but its a horizontal sync problem.

if no change the horizontal processing ic.

Flickering horizontal lines


sounds like a problem in the horizontal deflection circuit.possibly a solder problem. try re-soldering the horizontal transistor, line coils and yoke pins.
