Picture fuzzy and blurry when switch on and as set gets warm picture quality returns


This being a rear projection says that the color guns are going out. It will be a single gun or three individual ones. You will have to take the back off to find a part number and what type of color gun or guns you have.

After turning the tv on the colors are reddish and slow to conform to the normal color tones. i have a 36" toshiba flat screen tv


My first concern would be that, the picture tube is going bad. The problem you describe, tell me one of the color guns is shorting. In this case I would think the green gun is shorting. There are three color guns in the neck of the picture tube. They are red, green, and blue. Most of the time the green will short as it is powered heavily in most TVs. The next thing to check, is the small board connected to the picture tube. Look for any and all bad grounds on this CRT board. This is another big problem in all Tube type TVs. On this small board there will be three color output transistors, and resistors. These will many times run very hot and will create bad grounds over time. Check and resolder as necessary. If the CRT board does not fix your problem, replace the TV. Picture tubes are very expensive and will not be feasible for replacement. Search for a new TV. Thanks for asking and show all hands of support!

The tv is at least 17 years old.The blinking red light blinks 5 times ,then the tv picture goes off . The voice is still on


Five blinks is the error code for an AKB (auto kine bias) error. What this means is that the set isn't able to balance the three color guns (red, green and blue) of the picture tube properly, and it's blanking out the screen.

To get the proper colors, the signals for the three colors need to be balanced, and Sony sets have circuitry to do this automatically. Other brands don't, and when they go out of balance you see a picture that starts to show tinting or colors that are off. As the picture tube ages, it gets harder to adjust the balance until finally the AKB circuit can't anymore, and poof, the picture goes away. With a 17-year-old tube, it's not surprising.

There isn't anything that can be done to fix the picture tube, it would need to be replaced. But the cost of the tube and the work required to get it set up after installation makes it completely uneconomical to repair this TV. A new picture tube is nearly $200. Then special tools are required to set the tube up (a process called convergence), so you'd need to find someone to put it in, and possibly pay to have the old one disposed of. A new 32-inch LCD set is around $350 now. Treat yourself to a new one.

I just need to adjust the resolution on this TV. NO ONE at RCA could seem to help me. Thank you.


hi,
did u mean to adjust the picture setting then go for the following
1 press menu on the remote
2. using down arrow select picture quality and press ok. available options in picture quality and its use is listed below. you can use it according to your preference.

Basic Picture Control- Displays the five slider controls for adjusting

the way the picture looks.

Contrast Adjusts the difference between the light and dark areas

of the picture.

Color Adjusts- the richness of the color

Tint Adjusts the balance between the red and green levels

Black Level Adjusts the brightness of the picture

.

Sharpness Adjusts the crispness of edges in the picture.


When exiting this menu, the Save Personal Picture Preset choice list will

appear. You can choose either Yes or No. If you save the settings as a

Personal Picture Preset, the TV will store the settings so you can reselect

them easily if someone changes the settings.

Picture Presets Displays- a choice list that lets you select one of three

preset picture settings: Bright Lighting, Normal Lighting, Soft Lighting

or Personal Picture Preset. Choose the setting that is best for your

viewing environment.

Auto Color Displays- a choice list that lets you turn on the feature that

automatically corrects the color of the picture. (This is especially useful

for tracking realistic flesh tone colors as you switch from channel to

channel.) Choose On or Off, depending on your preference.

Color Warmth Displays- a choice list that lets you set one of three

automatic color adjustments: Cool for a more blue palette of picture

colors; Normal; and Warm for a more red palette of picture colors. The

warm setting corresponds to the National Television Standards

Committee (NTSC) standard of 6500?K.

Video Noise Reduction Displays- a choice list that lets you turn on the

feature that automatically reduces noise from the picture. Audiovariable

enables the TV to automatically adjust noise reduction level;

off turns off noise reduction feature; on-fixed sets a fixed level of noise

reduction.

The picture is a red color


A lot of these sets develop a problem like this--the set uses a small plastic block with 6 controls--three are focus and three are SCREENS--

most likely you just need to get at and turn the red screen control down just a little.

I can tell you how to do this from the front of the set--takes only a few minutes.

17 yr. old 35" RCA loses color intermittently. Picture & sound ok


Three guns Red Blue and Green in the picture tube of an old CRT set. If one of the guns goes out it effects that color. Sounds like one of the guns inside of the tube is going out, To costly to replace for such an old antilog set that will have to have a convertor box next month anyway.

If you have not already done so go into the picture menu and set the convergence. The convergence is the angle at which the three picture tubes meat at a given distance. The tv will have at least 3 and up to 64 convergence points, and those 64 can be set for all three colors. This can be tiresome but I'll be it will solve your problem. What your trying to do is get the color in the cross-hair so you cannot see the color behind the target. On top of the fine setting for each point and color you will probably have 3 gross adujustments for blue and green and maybe red. These adjustments will affect positioning, like what you are discribing. You should do this at least every month, the thermal cycleing of the lamps is what will cause this to creep out of adjustment.

I have a similar problem. I have tried to fix the convergence via the remote and that has not helped. My three colors are separated and the edge of the picture is bent in toward the center. I am going to try a hard reset but i suspect the convergence IC are fried. Since the set is not HD, I will probably replace it if the hard reset does not work.
