Question about Samsung HLN5065W 50" Rear Projection HDTV-Ready Television

1 Answer

Green lines in TV

Off and on for the last 6 months my TV will get these horizontal green lines in it. Sometimes it's just a few lines here and there and sometimes they are all over the screen. (see picture below) There is no specific time when this happens and it comes and goes. Sometimes the picture is perfect. The TV is 5 years old and has been used very very little. Does anyone have any idea what is wrong with it?

Take the TV cabinet apart and unplug and replug all the circuit board connectors, that may fix the issue.

This TV needs a service adjustment done. Looks like a vertical or horizontal IC is failing. I'd go ahead, and shut off until services adjustment is made. Have you unplugged for a few minutes and plugged back in? However, I'd have a service tech look at it.

SOURCE: Samsung DLP TV shows green color where color should be black

This could be your video board going bad where your input cables are connected --OR-- the color wheel going bad. Hard to tell without a photo or reference though. Try swapping the cables first... and listen for any winding or whirring sounds.

Horizontal Green Lines On Screen. No Picture Visible. Problem is intermitent.


Are you certain of the connection? Sometimes the connector becomes loose or otherwise loses integrity. Maybe it's the cable (HDMI, right?)--or both the TV's connector and that. They may become worn.

Be careful with your LCD screen--they are more delicate than most people realize.....

After a period of time, vertical lines appear on the screen. Looks like jail bars. Sometimes turning the TV off, then back on will clear it. All channels. I replaced the projection bulb about 6 months...


no solution, same sounding problem though. last year we were getting lines through the screen and flickering and then the bulb burned out. had it replaced, 2 months later it did it again (they wouldn't stand behind the bulb so we had to buy a whole new one) this time had the bulb and ballast replaced because the repair guy said usually you have to replace both (why didn't they replace them both in the first place?) .. a year later and it's doing it again.. we get the flickering of the screen going on and off and horizontal lines that flicker across it. after turning the TV off and on a few times it seems to go away (or after it warms up)

i know know if i should order another bulb and ballast and spend the money for it to happen again or if it could be something else

let me know if you find a solution.. carolynspranger@gmail.com

Hello: Have you tried to adjust you Green Screen control on the focus block assembly. located behind the front panel assembly. Here is a solution that might help you, turn off the green by turning off this control, make sure u look at the block and make sure you are not turning the green focus knob instead of scrn crl. Turning the control slowly to the left the retrace lines should disappear as the green video darkens. Then turn the control slowly to the right just until the retrace lines reappear, then turn back slowly left just until the lines go away. If the screen is Blanking on green tube only then you have a video blanking problem on the main signal board. Or possibly a IK bias problem. It is also possible that the green CRT is defective. The FBT is not bad because the screens are lighting up indicating you have high voltageand heater voltage which is derived from one of the secondary windings of the FB. If it is a Blanking problem i would look into replacing the A Board assembly.

Green picture with horizontal green lines...


John,

First, Id like to know how old is your unit? Also, the lines indicates in issue with regards to the lifespan of your tube. The dominant green color has something to do with a malfunctioning ray gun of your tube. However, i had encounter a unit that was resolved by simply resoldering the circuitry of same problem.
Why dont you try to resolder the board first.

Response is highly appreciated.

Unfortunately there isn't any way to repair your tv as the magnet has distorted the tube that is in the tv and with CRT becoming obsolete the repair is likely to be very costly so probably your chaepest option is to buy a new tv .

Green Convergence


Hello, I have the same problem and was told that I needed a new convergance chip. They told me who deals in the problems where I live, (TV Repairman) It will cost me 300 for a six year chip and 350 for a life time chip! I was told by the repairman that these chip only last up to 6 years if they are not lifetime. I see alot of this same problem going on right now. These tv were manufactured in 2001, but no one was ever told that these chip would need to be replaced in so few years after spending all that money on the TV. Pasonic would not tell me the price of the chip nor how to get one,were very unwilling to help with the problem other than telling me who do go to locally, so you would have to go thru a tv service where you are.

Green horizontal lines across screen


try adjusting the green screen control. remove the front bottom panel of the tv by removing any screws holding it in place. gently pull of the front panel, there are gromets holding it in place, you will be able to gently remove the front, just make sure you get all those screws. now reove the small wodden or plastioc panel. now you will see the screen/focus assy. check to see of the screen controls are the top 3 or bottom 3. adjusted the center screen it's the green one, the other 2 are the red & blue. it is best to adjust in a dark room where the lines will show up easier. good luck
