    It may be---some parts are not available--I have a thought---if you open the rear cover above the boards is a metal channel that runs left to right--look for any signs of a white residue in it--these sets did have issues with Glycol leaking into that and from there down onto the boards under them, if find that retire the set and if see any clear liquid, even a tiny amount do not touch it--toxic stuff.

A educated guess here (model is a rather old Sony) this set will blank or shut the tubes off if loss of vertical or horizontal deflection---the slight line at top suggests vertical

What I have done to confirm this is either use a scope and check for deflection or turn blue screen up slowly(blue is less likely to burn the tube screen) and see if just a line.

The set blanks the tubes to prevent a line being burnt instantly at normal brightness (all concentrated into a line) on the face of the tube.

If you are technical and have a volt meter you may be able to locate online a free copy of the service manual to check voltages etc.

are the lines slightly curved and go from the botom to top across the screen. If so it sounds like retrace lines from the CRTs being turned up too far. You can add the pic by clicking the camera Icon next to where it says Insert below the text box.

I have a hitachi rptv model #43FWX20B and the picture has a red tint to it. Opened back up and red green and blue bulbs light up. red bulb stays bright while blue and green go dim to bright as tv plays....


Howdy;
Since you don't have any white lines with the red screen/picture I would say that the red bulb (CRT) is conducting too much. There is an adjustment control for that. The 'sceen' control is behind the speaker cover and service cover. Turn red screen control slightly to the left until you get a good black and white picture.

Good Luck, Big Irish.

Turn the top left knob down till the pic comes back and the reason your color is off is the fluids in the green and blue chambers needs to be changed.

Replaced bulb, picture is really dim. Same with the next replacement bulb, it's not the bulb


There are also three light imagers or optics in your set one for blue one for red and one for green could be the power supply driving them or they are bad. I had same problem with a Sony 50we610 first rear projection lcd line released most have had this issue.

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!!!

Z3 projector.3 years old. Blue tinge in one corner of projected picture. Grainy picture on dark scenes.


There may be some problem with your picture tube else try this that looks like retrace lines. Anyway, you should try to adjust screen pot not focus pot. Make sure you are turning blue screen pot (there are 3 focus pots and 3 screen pots) and do it slowly. If you turn it too much, it will affect your grayscale

Tune up for Hitachi 60FX32B


Remove rear cardboard cover....can you see tops of red / green /
blue tubes ? Clean lens' with soft , dry cloth......Do you smoke ?
If not , replace back. Picture should now be clearer but not
necessarily brighter.......Next, remove front speaker grill and find
the RGB focus / screen adjust block....turn RGB screen controls
SLIGHTLY clockwise to achieve more brightness....not too much
or you will have retrace lines in background of picture.......Let me know after these steps are done........T.

Blue vertical lines - no picture


you did not mention if you have sound.but if you have sound your problem is in your video and vertical section.if no sound then you have to look into the IF section.if you are not a tech then you will have to take your set to repairman.goodluck.the tuner must not be over looked.an estimate of about $200.00 could be less.
