SOURCE: Dark , blurry picture

MTNESTR, My guess would be the FBT loc.TH01(flyback transformer) Hitachi p/n#BW03004 which would be far less expensive than replacing the entire deflection board... A shop could ring test the FBT to confirm the failure. I do know the FBT in this unit has an internal resistor that is prone to failure. It is in-line with the focus block and if it's open it would explain the blur and lack of screen voltage to light the crts properly. The deflection board is about $290-$350 plus shipping and a FBT is somewhere between $60 - $90 depending on the supplier. Hope this helps! Bill

Vertical position does not work on remote. Magic focus on green goes half way stops then number five comes on screen. Hitachi 51inch rear projection tv


Magic focus on a Hitachi only adjusts at 16 points on the screen and needs to be done in a dimly lit room. Frankly its a sales gimmick, the number 5 means one of the sensors inside the screen for the Magic focus is not connected or bad.

Go into the tech mode for convergence with the original remote (that menu is called the Decam mode) and see if convergence will adjust there. There are close to 120 points that can be adjusted there as opposed to less than twenty in the magic focus mode.

Picture quality is very dark.


Well, that explains a lot----mirror or the lens or even the screen may be coated with grime-----be careful if you attempt to clean that screen, easy to damage and expensive to replace--what about the mirror and the 3 lens?

I need to replace the dust cover on my Hitachi 53SDX01B


the problem here is Hitachi usually if it still has it sells all three screens as a unit---expensive.

You may want to search with GOOGLE the internet as some companies sell replacement "protective" screen replacements.

I have even seen one time someone found a piece of plexi-glass and had it cut to the exact size and thickness for a replacement.

Red Lines through picture when screen is dark, back ground has a red tint. On my 48 "Sony Rear Projection" TV


You can try adjusting the Red color output. (Very touchy adjustment)

If you take off the front cover/speaker cover, there should be a access panel. Behind that, there should be a small square black box with 6 screws on it. This is the focus block. (At least this is where most of them are located)

It sounds more like you may need less red in the mix. There is a screw for each color. R, G, and B. Do not mess with the focus screws, just the ones labeled 'SCREEN.'

Go to an unused input where the screen should be dark. Barely turn the red down in a dark room so that the red spot is at the same level as the Blue and Green.

Use an insulated screwdriver and DO NOT TOUCH the focus block and ESPECIALLY NOT the back of it.
Very HIGH VOLTAGE. I found that out the hard way.

Do not turn any of these up too high or damage may occur and the TV may detect a short and shut off.

I have found that if the three colors are adjusted in a dark room to where the 3 color spots (R/G/B) are just barely visible on the screen at equal levels, there is a pretty good color balance.

I hope this helps! Just be careful.

Try adjusting your screen drves to tubes, you have a Focus/screen drive contol block that adjusts each Tube R/G/B, you could also have poor solder connection or leaky capacitors causeing Dark Picture.

Picture is very dark and color not too good.


Take the front speaker grille off; it is stiff but will pull off. Take off the access panel underneath; four or five screws. Inside you will find a screen/focus block control assembly. Get a flashlight. Turn up the screen controls SLIGHTLY. for RED, GREEN AND BLUE. The best way to do this is to turn off the color first and make sure you end up with a good black and white pix ( not tinged green, red or blue) then turn the color back up in the menu.

Dark background blue tint


Try the Magic Focus option on the menu screen found under "Picture". Make sure the TV is on for 20 minutes before activating this option. It is also best to run this when the room is dark.
