Question about RCA F27649 27" TV

RCA CTC203 no red colour

Hello I had a problem last week where the screen lost the picture and went to just snow and red. I looked on the internet and it suggested changing resistor R15101 on the back board. I've got the picture back now, but no red on the screen. Today, I was watching US open golf, Tiger Woods was wearing a red shirt, but the TV showed it as blue. Any other suggestions?

Re: RCA CTC203 no red colour

Did you change the resistor by yourself? I am not sure if your TV has manual adjust on the back of the TV that you can adjust. Some times turning the TV Off and unplug it from the wall helps because it resets the TV. Check your Back ground color and see what is the dominating color. Blue, Green or Red. If this doesn't work please call a professional to look at it.

RCA model #f27648 reds missing from picture

It sounds to be a video output stage circuit fault. Check all the solder terminals at its CRT base card, including the solder terminals of the CRT base to the card. Re-solder all the suspected solder terminals by applying a little more fresh solder. Contact any service technician. Check the solder terminals of Red color output transisotor. If needy, replace it with a new one with same number printed on it. If you wish to get some details; check the site linked here. Viewing it in "Mosaic" will make surf easy. Surf the site with patience. Pull up older posts there.
The fault is 'one colour predominant/absent screen'

Rca tv screen gone red

If your able to take the back off and have experience in soldering then you can look on the CRT board on the picture tube for cold solder joints, it should be quite visible. There are 3 transistors that look identical so I would look those over closely. Those are your Red, Green and Blue Video outputs. If you choose not to and want to take it in to a service center try and find one with Free Est. Notice on your screen if you have diagonal lines, if you don't, that's a good sign. Let me know what you decide!

No red

Losing one colour probably means failure of electronic components related to the particular colour. It is unlikely adjusting the red settings will fix the problem. Even if it did, the colour balance needs specialist equipment to properly set up.

Could you supply me with the chasis number from the back of the tv E>G ctc203 at113. With this information , I can tell you probably what the problem is and approximately how much it will cost to repair. Each Rca has its own set of problems. Recently RCA/GE were purchased by a large Chinese Corporation. Some of the newer sets are totally CHINESE.Here are some of the common problems that would give you this symptom. Bad connections on the IHVY(flyback). Open horizontal windings in the Yoke. The original problem is problably due to an inaccaure setting in either the red cutoff or red background. These adjustments can only be made from the servicemans menu and are not accessable to the consumer. The problems described are of a serious nature(except you original one). You may consider shopping for a new set , replacing it with an LCD. The LCD gives off no radiation and cost much less to operate (electricty) Scrivitron
