Faint Blue Line Follow-up Question for Maddogmic

Maddogmic, Thanks! You're solution was pretty easy to do. Just one question....which of the three lower adjustment screws should I turn. I assumed the left one was blue per your order given in the note below and turned that. They are probably labeled but there was white paint over the writing and it was very hard to see. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up.

Re: Faint Blue Line Follow-up Question for Maddogmic

This worked great for me, too; however, I was feeling ballsy and fiddled with the 3 focus adjustments as well. If you can get a solid lettering against a dark screen (like during the credits of a movie), you can fine tune those very easily (mine needed it).

Toshiba Model 51h84

The wavy when cold is a issue with a board in the set--Hyper board--the warmup until it begins to work will gradually get longer and longer.

The blue: look at set on a unused video input--if see faint curved blue lines with some blue visable on the screen the blue screen control needs to be adjusted just slightly down until the blue and curved lines are not seen.

Faint lines show up when i get dark screens in movies

First check what color of faint lines comes then reduce Screen Volts in TV of that CRT (tube)
Take off lower front cover, speaker grille of TV, there you will see focus control block that has 6 control knobs, upper 3 knobs are focus adjustment of red-green-blue CRTs and lower 3 knobs are screen volt controls for red-green-blue CRTs. Turn screen volt control knob CCW to reduce screen volts of desired CRT.
Put TV on any free AV input so screen will be dark enough to adjust screen volts.

You have a completely different problem. The screen voltage for the blue picture tube is slightly too high on your set. This will put fine lines in the background of the picture, called retrace lines. This is very common and easy to correct. Remove the front speaker cover and the access panel behind it. Look inside and you will see a black box with six controls, each control having a little white glue on it. This is the Focus/Screen block. Three controls are labeled Focus and three are labeled Screen. The screen control in the center is for green but I am not sure if the screen control on the left or right is for blue for your model. With the TV on, set it to VIDEO 1 but do not connect anything to the VIDEO 1 jacks. This will produce a pure dark picture, showing any faint lines in the background. Choose one of the screen controls and increase (turn clockwise) it slightly. If the blue lines do not get brighter it means you are turning the red screen control, so put it back where it was and choose the other screen control. When you find the blue screen control, decrease (turn counter-clockwise) it until just when the blue lines are gone. If you want you can check that the red and green screen controls are set to just below the point where their faint lines are visible. When done, replace the panels and your picture will be back to perfect.

MikeNJ1964 was exactly right! I have a Sony KP-65WV600 that had horizontal green lines that showed when the picture was darker. I had to remove 3 screws on the right and left side of the tv holding in the speakers...carefully pop out the middle panel from the clips holding it in....remove 4 screws from the cardboard in the middle and remove the cardboard. I then saw the six screws. The adjustment screws were the three below. I turned the middle screw until the lines dissapeared. I tried the left screw and blue lines appeared which I then adjusted away.
THANKS a bunch. SAVED me money!!!

I have a line that goes from the top to the bottom of the screen, when on the blue screen I can see it well, but when watching tv you can see a faint yelloe line in the same place. (right side of screen)

I have a toshiba plasma 1080p thats all I know, I see the line the clearest on the blue screen, you know when you change to an imput that has nothing using it, and when watching tv or games a very faint yellow line you gotta really focus on to see. But I wanna make sure this is not gonna get worse. Thanks for your response let me know.

I have a hitachi projection tv that has yellow areas on the screen. tv repair guy says it is the engine. does this make sense? in checking tv repair on line it seems to me to be the projection lamp. does...

When tv has a blue or red or yellow circle in middle of screen and it is very faint looking in most cases it is the light engine.
The cost is 650,00 plus labor. In some cases it could be the color wheel. but rear .
The lamp is not the problem

I got this TV for FREE from a guy posting it on craigslist because he saw "BLUE SWIRL LINES" also knows as "Retrace Line" on the screen and he went to several repair people and got high repair costs so he was giving it away for free, but i found a guide that tells you how to adjust the tv to make the blue or green or red lines go away, aparantly the line show up because the voltage on the color ray gun tubes that get out of adjustment. Here is the Link to the REPAIR GUIDE.

Faint blue arched line across picture

I had the same problem with my sony KP-57ws500 rear projection tv. To solve this problem all you need is a flat and phillips screwdriver. Right below your speakers on the right and left side are tabs. Pull out the tabs and remove the screw on eachside. Once that is done remove the speaker cover and you will see a fiber board cover in the middle of the tv, there will most likley be twist ties holding some wires, to make it easier to work remove the ties. Now remove the screws on the fiber board and pull it off. You should see 3 adjustments on the top for focus, do not touch those. Below the focus adjustments on the bottom is the blue, red, and green adjustments (they should be labled). All you have to do is turn adjustment screw slightly to the left(or counter clockwise) and it should clear right up. I'm not a technician but i read up on it in a repair manual and it worked perfectly and saved me a $100.00 for a service call. It took about 10 minutes to do. I also have a friend who expiernced the same problem with a different model sony projection tv and it worked for his also. Apparently this is a common adjustment that needs to be made espicially if the tv is moved.
