RCA MM36100 color problem

The TV works fine until the other day. When I turned it on, the color was all messed up. The colors forms 3 static rings on the screen, the blue in the center, green in middle and red in outside. The picture displays OK, just the color is no longer moving with the object on TV. So now I am watching b/w TV with 3 color rings. Please help. If more info. is needed, I would be more than happy to provide additional info. I wish I can put a picture here.

Sounds like you have a deguassing problem with your TV .. have the repair person bring out a deguassing coil and see if thsat helps.. This will only be a temp repair as you will have to have the problem that caused this to be fixed. good Luck

Why are my tv colors so messed up?

Check the color system setup. Make it 'Auto'. Refer its user manual for details. If this do not help you, chroma section circuit should be checked. It is a skilled job, and need tech support.

I have an RCA 36 inch tv, the color is messed up, it has a round circle and it will not change channels

If the set wasn't dropped or physically dammaged the chances of it being the picture tube is very small.
The set is probably magnetized and needs degaussing (demagnetizing).
All CRT type TV's have an internal demagnetizing circuit that is engaged when the set is first turned on after being off for the day.
If this circuit is working then you sometimes hear a "bonk" sound (about 1/2 a second long when the set is first turned on. If this circuit isn't working the set will become magnetized over time and will have to be degaussed using a degauss coil available at a TV repair shop (cost aprox. $35.00) and you should have the circuit checked at the same time. A set will also become magnetized if a large speaker (magnet) or motor is close to the TV. Be sure to vote/rate me if this helped Thanks!

There is a common problem in this unit with R14103 (33k 2watt ) resistor that opens. When open SMPS will not load so no other voltages beyond the 5v source to click the relay.
Another possibility is the Horz. drive transformer, RCA p/n# 243859 board location T14451.
Either of these possibilities are inexpensive fixes reletively speaking, so I would advise having it estimated by a qualified shop for repair..

Color messed up

Most likely your visitor turned one of the controls located on the back of the TV. There are only two controls they are the right side of the set in the back. The top one is the focus and the bottom one is the SCREEN control. You can carefully rotate clockwise the screen control until the brightness is back to normal. If you go to high with it you will see faint diagonal lines going accross the picture.

White Noise Sound

Your problem is somewhere between the tuner and video detector circuit. The signal entering your TV carries: video,red color,and blue color as well as sychronizing pulses for color and horizontal and vertical deflection ( actually vertical sync. is derived from horizontal sync.) along with burst pulses to synchronize the color. After all these, the sound is an fm signal entwined with a pilot signal for stereo audio. WHAT a mess! After the audio passes through all this, it is detected and sent to the audio processor. If any frequency has drifted away from it's value then you loose the sound. SO... your problem could be in any of the tuned circuits or in the audio processor IC (chip). Any component changing value could creat this problem. Most likely the audio processor IC. You'd need to have the set checked out by a tech to find your problem. Stargazer
