Hi.

There is a service procedure to setup convergence. The steps depend on TV make and model.

If the alignment cannot be setup with the procedure, then there is a fault, usually the convergence ICs must be replaced.

Note: blue patches and screen too blue may be symptoms of a different problem. Convergence symptoms are colors not matching and bowed screen with bands at top and bottom or at the sides.

RCA rear projection tv picture bowed to middle. Red Green Blue colors have been seperated on screen.


If I had to guess I would say it's either the DLP chip or the prism. Simply put the lamp lights the DLP chip which directs the light into a prism and then onto the TV screen. The prism or prisms are responsible for aligning the colors correctly. The DLP chip is essentially a million little moving mirrors which direct light

If you're at all comfortable with electronics you might want to open the TV up to take a look. You might get lucky and find something obviously wrong with the TV. Sometimes adhesives melt and parts slip out of place. If your DLP chip is blown there isn't much you can do. You're probably right that this would cost a lot to fix and not be worth it.

Hello linda, hi, I dont think the remote or manual can help the color issue problem, the tv needs to be looked at by a qualified technician. If the TV is a tube type, there are magnets on the neck that needs alignment, this alignment is done while the TV is ON. so high voltage risk are likely. keep out and call service.

Your convergence is out. If it's just out a little, you can adjust with your remote or with older sets there are knobs. If it's way out then your convergence block went out and you'll need to replace it yourself if you're technically adept or take it into the shop for repair.

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.

53 inch projection tv...seems like the color red and color blue have shifted giving me a picture with red and blue shadows


For CRT projection TV's, this indicates that the Green picture tube is burned (warn out). The less green that strikes the screen, the more redish the image will look. You will need to find an old school TV repair shop that knows how to replace picture tubes.
In the case of a DLP style TV, the color wheel needs replacing.

I HAVE A 50 HLM507W SAMSUNG TV WILL WORK FINE FOR 30 MIN THEN COLOR WILL GO GREEN AND BLUE AND STREEKS OF WHITE LIKE LIGHTING


When these colors show up if you can still see the on screen menus with no issues then more than not your digital board is bad. If they are not visible and are distorted as well then the DMD board is bad. Either way both are technician replacement items as the set requires alignment after either one is replaced.

I have a 56" toshiba dlp. It has a red have throughout the screen. sometimes worse then others. Is it the bulb? color wheel? Is it something I can fix? Where do i get the parts.


This sounds like the alignment of the red beam is off. There is usually a configuration tool in the menu that shows a white cross in the center of your TV against a black backgound (if it's aligned properly). It's a combination of the red, blue and green light bars hitting the screen. You should be able to adjust the positions of these crosshairs for each of the colors and "fine tune" your picture. Some of the higher end TV's even do a grid with over 100 crosshairs to fine tune every few inches or so. Once you get the red beam in line with the others and save the settings you should be good to go!
