Not a clear picture


CRT projection televisions need periodic maintenance to maintain a clear picture. Typically, to maintain a sharp picture, they require cleaning and alignment every two or three years. If the television is being used in an environment where there is cigarette smoke or other smoke sources, the optics inside the television can become dirty and cause the picture to blur. Additionally, CRT focus and alignment wander over time, or physical CRT alignment can be knocked out if the set is bumped or dropped. All RCA CRT projection televisions have an "alignment" or "convergence" adjustment in their adjustment menus, which are fairly simple to use. The convergence feature is usually accessible from the main menu of the television. Check your User's Manual for the procedure to touch-up the convergence adjustment and see if you are able to achieve a sharper picture. If the optics in your set have not been cleaned for several years, or if it is in a smoky environment, the picture will be blurry and usually a brownish color, In any case, since the set is several years old at this point, it's likely due for a cleaning. This is best done by a technician, and mostly involves physical cleaning of internal lenses, the refractor mirror on the back of the chassis, and the back of the opaque display screen. An adjustment of CRT bias controls and individual CRT focus adjustments will bring further improvement in the image sharpness and clarity.

Tv out of foucs


These procedures are from the owners manual, go into menu and then picture quality and then: Convergence The Convergence feature lets you adjust the TV’s three tubes. When the TV tubes’ images are precisely aligned, they create the color images you see on the screen. Over time, the picture can drift out of alignment (this is normal). If your picture seems fuzzy or has a yellow tint, using Convergence could correct this misalignment. Only one convergence is needed for all inputs, regardless of the signal format. Note: Make sure the TV has been on for at least 30 minutes (TV needs to warm up for best results) before starting Auto Converge or Red/Blue Centering. When you select the Convergence feature, a submenu appears with three options: Auto Converge Automatically aligns the projection lenses to self-correct color images. You’ll see flashing squares of color dance across the screen (this is normal). Note: After performing auto convergence, use the Blue Centering and Red Centering menus to fine tune convergence in the center of the screen, if necessary. Blue Centering Aligns the blue and green images to fine-tune the picture. Red Centering Aligns the red and green images to fine-tune the picture. Note: The ability to change channels is disabled when adjusting the convergence options. The TV must be tuned to a usable signal to converge the picture.

You have problem with convergence. Have you tried adjusting in the users menu. This is a common problem in this type of TV, usually two convergence amp need to be replaced and sometimes sets of resistors are also to be changed.

Tv projecticg 3 images in red blue and green


Your convergence probably needs to be adjusted. Somewhere on your menus will be an entry for Auot Convergence or just Convergence. The TV will normally display a set of lines in 2 or 3 different colors. You would then adjust the lines so that they line up perfectly. That should take care of the issue.

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)

TO ADJUST IT MANUALLY:

Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.

Hitachi 43fdx20b blurred Picture


Yes this is a normal diagnoise. Just about every Tube type projection TV set ever made will one day need these IC's replaced. They are not really that hard to replace but you would need to know how to solder and unsolder on printed circuit boards, know the procedture, and then have a service manual handy to adjust the convergence after yoou replaced the IC's. If the tech works on alot of these types of TV sets's, most likely they could adjust them without having a service manua handy. This repair done by a pro should run you anywhere from 250 on up to 400 bucks depending on who does the repair and where. Good Luck
