Question about Televison & Video

1 Answer

RCA 52" Picture just went from fine to seeing different colors hazing each other. When there is lettering on the screen you can see it in blue, red, green, etc, everlapping each other looking like they are not lining up on each other like they are supposed to, same with picture. Tried leaving it off for a few hours and even tried unplugging it for an hour. Still has same problem. looks like it has an upward bow at the bottom of the screen and a downward bow at the top.

This is a convergence problem and can be as simple as bad solder connections at the convergence ICs or defective ICs. Can you solder? If so, update this and repost the model number as I don't have your original post.

Thanks,
Dan

The picture is a little distorted. Any numbers such as the channel or letters show up double and in two different colors.


There are two ways to do this
1) go into you menu and there should be a opportunity to align your color guns,
I found red was the outside square. Mine didn't fit right.
green/blue were crosshairs/
If done right the green/blue should merge and the red should fit your screen if they do not do that, then you need a service guy who knows how to physically adjust them.
I call in a guy and they are very reasonble. and what a difference

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.

Our 1991 RCA P52150CP rear projection TV has gradually been getting bright cloudy blue, slight haze around letters & shapes-(especially blue channel change headings) when first turned on and then it...


Hi

First check whether all the cables from your dishnetwork are fine and connected firmly.If yes then you'll need to pull off the front of the tv, behind the speaker grill there would be a panel. Remove the panel and check for a black box hanging over there. It has 6 controls on it, 3 are marked as focus and 3 as screen. You'll need to adjust the screen. If you turn these too high you can damage a tube. so we are doing real small adjustments. Turn the color off on the tv and adjust the red, blue & green controls up till you get a fine picture. Also adjust the focus until you get a clear picture.

And, if it doesn't resolve your issue then it is an intermittant blue picture tube, a bad blue driver transistor on the CRT board, a bad connection on the blue crt board, or a problem in the RGB coming from the video jungle IC. A set this age, most likely will run you about 300 to 500 bucks to have this problem fixed, unless it is the picture tube.

Please do accept this solution and revert for further assistance.

Thanks
