    I have a strange menu up that won't go away.  The power button on the TV is broken and the remote won't work when this strange menu is up.  I tried to unplug it, but menu is still up when plugged back in.  The menu button just scrolls through options, the volume just adjusts. What to do.

Just got this tv from friend. has no remote. screen is black. sound is good. when you push menu button, white line goes across horizontally the screen.


The horizontal line indicates the vertical deflection circuit is not working. Either the set is stuck in service mode for adjusting color (turns off vertical), or the deflection circuit has failed.

Some RCA TV sets have a "Service" switch in the back, down near the bottom of the set. Most of the newer sets use a combination of remote control and front panel buttons to get into service mode, and that can be turned off by unplugging the set and plugging it back in. Try looking for the mechanically operated service switch in the back first.

1) I have a Sony KV-32FS13 that has a green tint in the picture. Does any oneknow how to access the service menu for this model? I tried other adjustments and I can't get rid of the annoying green...


Code 5 is "AKB error". AKB, or auto kine bias, is a cicuit that monitors the three color guns of the picture tube (red, green and blue) and tries to adjust them for proper color balance. If it can't, the picture is blanked (usually) and the timer/standby light blinks 5 times. When the color drives aren't balanced, you see a color tint in the picture like you're describing.

There might be a problem in the AKB circuit, or the picture tube may just be old enough that the AKB circuit has run out of adjustment range. If the tube is at fault, you should consider replacing the set. A new tube will cost nearly as much as a new 32-inch LCD TV, and you'll need to pay someone to install it and set it up. There are special tools required to perform the convergence which gets the color guns aligned with the face of the tube so they hit the right colors.

If you'd like to try tinkering with the service menu adjustments, this site explains how to access the menu and gives a list of settings.

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.

There is no much convergence adjustment inside service menu. Yes color it has RGB drive adj. but if not touch it will not change. Convergence mostly adjusted mechanically (check your purity magnet and yoke mounting). Hope it helps

Too much yellow in picture


The problem with the set is that the blue gun has gone weak, and not emitting at par with red and green guns in your picture tube. Turn of the blue screen and get the grainy display on the screen (detach the cable) and enter into service mode to fine tune until you get a perfect or black and white grain pattern.

Cant locate or adjust the the TV color


All the controls should be accesed thru the on screen menu,your remote should have a menu or display button and if you press it on the screen of the tv you should see a list of different options ,I am not familiar with the kind of menu that your set has but I know the color adjustment should be in the same screen that allows you to change the brightness,shapness,tint,color and contrast,the more you use the menu and become familiar with it the easiest it will be to use.Let us know if you need more information.
