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.

RCA 13R400TD 13"

It's a sign of a failing capacitor or transistor. It is not user serviceable part. The problem is intermitent but will exhibit itself after the unit has been on for sometime. Warranty of these units are usually 90 days labor and 1-year parts. On a sale, a 13" TV can be bought under $75. May not be worth repairing especially when a service facility charges diagnosis fee to open and zero in on the problem.

On your next TV purchase, you may want to register it here at fixya and avail of their extended warranty.

Tv turns on, but when you turn it off it won't turn back on.

sounds like its a cold solder connection somewhere in the set or a capacitor thats bad in the power suppy.. These problems are the most dificult to troubleshoot unless they happen all the time.sorry I wish I could give you more info..
