Just bought the Samsung Galaxy s6 edge yesterday. After I charged the cellphone for the first time and turned it back on there was this straight.

Sound like your Y-Sustain board has one foot in the grave. The Y upper buffer and Y lower buffer boards go when the Y Sus Goes too...

Please provide more details. Is this red line seen across the screen?

I have seen this many times . most people would said video card but for a fact i use a monitor with 3 red lines down the screen for a test monitor . the monitor has failed .

If its a kp-51hw40 : go to an unused video input and look at the screen---if it is redish in the background with curved faint trace lines you have one of two things wrong; First: the red "screen" control may be set too high. Second: you may have a problem with the RED picture tube.


To try to adjust the RED screen down you have to remove the entire front grill plate on the front of the TV(some have screws on the back on either side that have to be removed---and then you should be able to pop it out. Behind it there is a masonite inspection plate held in with screws----Once you have that off look for a SMALL SQUARE BLACK PLASTIC BLOCK; it has 6 black adjustable controls---you have to use a flashlight and look carefully---one row left to right will be marked FOCUS--DON'T TOUCH THOSE---THE OTHER ROW left to right will be marked SCREEN; if you look carefully you will see marked by each r (red) g (Green) b (blue)
you want to locate the RED SCREEN CONTROL.

WITH the set still on a blank video input where you can see it clearly turn the RED Screen Control to the left until the lines and red tint go away---do this slowly and make sure you are adjusting the RED screen--not the FOCUS.


IF this has been helpful give me a vote here as I do this for free; yesterday I adjusted one of these in a home that was blue with the faint lines---about 15 minute job for me.

These are retrace lines. The screen on the red tube is turned up too high. Inside the set there are 6 knobs. 3 for focus & 3 for screen. Turn down the red screen until lines are gone. These knobs are usually found by pulling of the front panel.

I will assume from you description that this is a rear projection crt(picture tube) tv. if this is true I have good news/bad news.
faint red horizontal bowed lines in the picture indicate the screen(G2) voltage for the red tube is too high.Slight lowering of the G2 adjustment will eliminate these lines. I stress SLIGHT because too much adjustment will mess up the gray scale .
The bad news the red crt made be bad. if the adjustment works but in the future the problem reappears then suspect the red crt.red crt replacement is probably not economical to repair.

Uh-Oh.. Sounds like the BGA RAM in the video circuit. (These units are Intel based and Core 2 duo if posted correct).. We can repair if you need help and its under warranty and sorry its not a home remedy situation..
