The picture on the tv is blue red and green Above is your user manual. Above and below aew training manuals, these show you how they work, and how to isolate issues.
It sounds like your "Mixer" has faulted, however what has "Caused" that, may be one of many things. This unit must have troubleshooting procedures to isolate the issue.
it is my professional opinion though that everyone should take their units to their manufacturers, RCA in your case, approved service center, contacting a local or head office, of your unit & getting an approved service center is just SO important, even worth the extra to ship it, you see, at those places, the Engineers, are trained on the equipment you have, they usually have parts on hand, and do the job quicker. Anyway do that and get a "Quote". This way, at least, you'll know weather to repair or replace

Acer flat screen tv - sound no picture?

Acer AL2671W 26in problems: (1) sometimes sound but no picture, (2) or screen freezes pink etc. (3) or remote won't turn it on/off (4) or it gives up and says "no signal". Turning it off/on usually solves it temporarily.

Tv turns itself on and off frequently

Check to see if this is an RCA CTC203 chassis (listed on back of set) if so there is common problem with bad solder connections in the horizontal drive section - Otherwise state the model for more help.
Be sure to vote/rate me if this helped Thanks!

TV is flickering

That unit is a ctc203 chassis and if it's never been in the shop before it's probably ring cracks in the HV or power supply circuit. Not an expensive fix at the shop and those chassis tend to be a bit of a bear dismantle (lots of smd). You might consider taking it in for a pro to look at it..
If not the chassis removes as a tray assembly and then dismantles from there. Good magnification, light, dmm and solder gun and you got it whipped..
Good luck!

32" model# F32668

The F32668 uses the CTC203 series chassis and I usually see 2 problems when the set will not run. The first is poor solder joints on a small coil near the horizontal output transistor, but if thats the case the set tends to run for a while and randomly shut off. When the set clicks and never runs I usually find that the flyback (high voltage) transformer has shorted out inside. In this case the flyback should be replaced by an experienced tech.

Tv F27442

The TV does not have a reset button. If you have no picture and no sound, there is something wrong with the chassis. In this case the set should be serviced by someone experienced in the RCA CTC203 chassis. If you have no picture but do have sound, then it is possible that the 2 controls in the 2 little holes in the back of the set are not adjusted correctly. This is quite possible since you said you put a screwdriver in there and got a fuzzy picture. The control on the bottom is called "screen" and is the overall brightness of the picture and the control on top is called "focus" and is the sharpness of the picture.
