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

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

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.

You`re probably getting a on air channel which means that you have to check your cable connectors and splitter if you got any, switch with other sets if you can.

JVC AV-32F702 Color TV shuts off after I power it on.

Any malfunction associated with a flashing light usually indicates a circuit problem or defective component. Unfortunately, the days of taking off the back cover of your TV and replacing a defective tube or fuse are long gone. Proper servicing will require troubleshooting procedures that can only be performed by a qualified electronic repair facility or professional television repair person. Ask for an estimate and a realistic appraisal of whether the set can be adequately fixed. Depending on the age and condition of your TV it may not be cost effective to repair.

Picture is now black and white

 First, confirm that the source is actually in color - try another channel or input device.
Next, check the settings of the color control - it may have accidentally been turned down. If your TV has some kind of automatic picture mode, try turning if off and adjusting the color control. Try adjusting fine tuning if you have such a control and the problem is with a broadcast or cable
At this point with a confirmed color signal source, there is a problem with the chroma circuitry.
Note that to the average person, the obvious question becomes: is my color picture tube bad? The answer is a definitive NO. It is virtually impossible for a defective CRT to cause a total loss of color. A defective CRT can cause a lack of a primary color - R, G, or, B or a short between two colors which will mess up the color but is not likely to result in a black and white picture.
Some possibilities in no particular order:

  1. Weak signal or defect in tuner/IF causing loss of signal strength.
  2. Coler killer set too high (internal control) if it has one.
  3. Defective part around the chroma chip/circuit. Faulty color oscillator.
  4. Bad connections in area of chroma chip/circuit.
  5. Defective chroma chip (don't suspect this first just because it is probably very expensive).
A service manual or Sams', DMM, and scope will help greatly in attempting to troubleshoot this unless it is an obvious bad connection. Try prodding the main board around the chroma chip with an insulated tool to see if you can make the color come and go.
I had one set where a $.02 resistor decided to open up causing just this problem - perfect BW picture, no color. Another had a coil with a broken wire.

Picture mostly green

In that case does this color problem occur on all inputs? If not then please make sure that the connections, especially the red connector, are clean and tight

Color problem

Please fine tune those B/W channels to obtain color picture. If TV is more then 4 - 5 years old, it needs resoldering in tuning area or might need replacement of IF block.

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.

Brightness of picture

If you feel good about opening your set then you can try this: Look for the flyback (high voltage) transformer, with the thick red wire which goes to the top of the picture tube. There are 2 controls on the flyback transformer, focus (top) and screen (bottom)Turn the brightness and contrast all the way down and then increase the screen control until you see retrace lines, and then back it down until those lines just vanish. Return the brightness and contrast to normal and adjust the focus control, if necessary, for a nice sharp picture. Let me know if that brings your brightness back.
