SAMSUNG HL-T5055 When first turned on comes up with a blue screen with five small black lines across the screen. After about a minute it went black. The lamp was still on. None of the controls seemed to have any affect and the set would not turn off. I unplugged the tv and waited for about 10 minutes.I then plugged it back in and it came on the same way with out any buttons being pushed. After less than a minute it shut-off and will not come on at all. The power light is red and there is now response to controls. I do not remember what the three lights were doing through all of this.

    Have you ever seen the original problem of blue screen with five black lines across the screen?

    If so what was the problem. My point is that I would have to buy a power board to try one. Is there

    anyway to check the power board ?

    The set did turn on with a blue screen and five lines across the screen. None of the cotrols would respond. It would not turn off.After a about a minute the screen went black. The lamp was still lit. I had to unplug the set to shut it down. Left it unplugged for ten minutes and tried it again. It turned on without my doing it with the same symtoms. I unplugged it and left it for a day. I plugged it in and did the same thing but shut off after a couple of minutes. Now it will not turn on .Just the power lite is lit and is red.

Black line inch thick right hand side


Get rid of it! I started out with the small black smoky line, went to two horizontal line, , , , I now have a 10 " line half way across the screen in two places and the rest of the line is 4-6". Contact Samsung three times on line and they responded with " we do not understand the problem, please explain. Oh yeah, TV was 2.5 years old. Never will buy Samsung again.

You're verical output IC is dead, this might because of a leaky capacitor on that section which causes the lines across the screen.
The processor shuts down the unit automatically to avoid further damage to your tube.

Send it to repair shop to isolate the problem. This is fixable.

Thanks for using fixya.

Sony KF50WE610 Vertical Blue Lines Across Screen


the vertical blue lines indicate some interference from other electronic gadgets near your tv. it started showing up on my sony grand wega when i installed my wireless modem. i almost ordered a new rear projection lamp costing over $100 but decided to experiment. i first moved my desk computer farther away from the tv then isolated the wireless modem router by placing it inside a small glass - the vertical blue lines became lighter in color so i dedided to find another small glass that fit inside the first glass container then put the router in the double glass - no more blue lines and my wireless modem router still works.
do some deductive thinking to figure out what's messing up your tv and isolate the interference.
good luck!

This is something that cannot be easily guessed at. There may be a failure in part of the power supply, and on one of the processor boards.

You will have to have the Samsung service rep do the necessary repairs on your set.

Verticle lines on screen


This is a very easy fix. Your cable box is not grounded correctly. To fix this you need a AC Plug adapter. This will change your TV ac plug from a 3 wire to a 2 wire. This may sound funny, but trust me on this. I have fix a lot of TV in NY doing just this.24001fc.jpg
