Question about Samsung LN-S4095D 40 in. LCD HDTV

1 Answer

Vertical lines along whole screen. Change in size, sometimes thick (480i) sometimes thin (1080p). Menu does NOT have lines going through it, only the picture. All inputs work fine but all have lines going through picture. Have tried literally everything, even tried updating firmware but still same problem.

user manual above.

Hi, there being no lines through the menus that tells, us what's wrong, in this case the Signal is either being affected in some way, or you have a bad antenna connection, or the Tuner is going faulty. Often this is caused by a broken braid, on the Antenna Coaxial Cable, or a bad connection in the back of the set, in the Plug & socket make sure all connection are nice and tight. Now if it isn't any of those, then it maybe the tuner, this is also a symptom of a bad tuner. Sometimes, it can be a bad earthing, on the equipment.
Now if all the other problems mentioned & they all turn out to be OK, then all we are left with, this is a tuner problem, these can be replaced quite cheaply, should that prove to be what it is, it can also be a bad voltage from the power supply, so this too needs to be checked.
To do any DIYing you must obtain a service manual, first.
However in my professional opinion you should take it to an authorised Samsung repair agent, and ask them for a "Quote" as to the repair, before allowing any repair work to commence.

How do I change the settings on my Westinghouse 50" TV from 720p to 1080p?


Most HDTVs these days do not have settings for resolution. They auto-adjust their resolution (within their specifications) to the signal being received. So, if you are receiving an over the air/cable television signal (most are 720p), you cannot force it to go to 1080p as it will not synchronize. You CAN adjust the aspect ratio on many models in the event that there is picture distortion due to screen size.

A few sets may have progressive scan technology as do some VCRs/DVD players. These sets create extra scan lines on 480i images and upscale them to 720i. This would be a menu setting if available and would only work in the conditions specified by the manufacturer.

Your TV is set to picture size of 1080p. Change it to "just scan" or automatic - the line should go away.

Vertical lines in my laptop screen


This could be a failure in several areas along the path from the video card to the monitor.

Being that there is not an issue across the entire monitor the video card should be considered a last resort check.

Usually this is caused by a loose connection between the LCD driver and the LCD panel itself. Sometimes light pressure applied near the affected line will clear it up. If that does then it is a connection between the LCD panel and the connector to the LCD driver at the panel's edge.

Not much can be done unless you have it repaired by a professional or you can take it apart yourself and apply a pad of some type inside the monitor's edge to apply the needed pressure once assembled.

Thin vertical line


What you have described is definitely some form of Electrical Interference. Interference can come from a variety of causes. Is the Cable Inputting the Cable Box close to some High Voltage Electrical Lines? Or Are you located near some Electrical Power Station? Or A Police station, where the Radio Transmitter of the Police Station causing the Interference? As I said, there are a variety of reasons. Also, Try to check if the connector is loose at the rear of the Cable Box, or at the rear of the TV. You will have to eliminate every possibility reason. Wish i could help further.
