Here's how to get to Service Menu:

Before entering the SERVICE MENU, confirm that the setting
of TV/CATV SW of the REMOTE CONTROL UNIT is at the
"TV" side and the setting of VCR/DVD SW of the REMOTE

been properly set, you cannot enter the SERVICE MENU.
1) Press [SLEEP TIMER] key and while the indication of
SLEEP TIMER 0 MIN is being displayed, press
[DISPLAY] key and [VIDEO STATUS] key (Fig.2)
simultaneously.
2) The SERVICE MENU screen of Fig.1 is displayed.

whatever is necessary (Fig.1).

If the line is vertical and "One Pixel Wide" (Pinstripe) then the LCD Panel is bad and needs to be replaced. Contact 1-800-SAMSUNG to set up service.

The capacitorson the FMT board have failed, which will cause that symptom. Is the menu screen clear when you hit menu?

Sure. I'm not sure if you can do it without the original remote, though. On my remote, you need to have the tv turned on, then press the sleep timer, then press the display and video status buttons simultaneously. This enters the service mode. Then, you should see an option for self-check (#2 i think). Enter that, then you should see 2 vertical columns of different inputs. From that screen, power the tv off. This resets all the ports on the tv.

Sounds like the green tube is shot, tap on the green board see if theres a loose connection, with something hard plastic

Hey guys, had the same problem. Found this solution on the web. Worked for me.
