RCA 32V434T (32'') TV has no Red or Green pixels, only Blue

RCA 32V434T (32'') has no Red or Green pixels, only Blue. It will power on for a few seconds, long enough to verify that the System Menus can be accessed, channels will change and audio is OK. Red power light on front flashes 19 times (if thats an indicator of anything) then it shuts itself off. Disconnected from AC for ~10 minutes with same results.
Ideas anyone??

The color problems are caused by cracked/broken solder joints on the circuit that controls the display.  Usually this is located at the back of the tube on a small circuit board. Your description suggests that only the blue signal circuit is intact. I suggest these joints be resoldered for more strength.
It's a possibility that another IC senses this problem (or another one) and then shuts down the system.
Resolder those joints and see what happens.

I have a insignia LCD 32'' TV and it have sound but the screen is green please help i use the component blue green and red


It sounds like the RED cable is not connected right, you did not mix the RED for audio right channel RCA plug with the RED component RCA plug? Please verify the RED, BLUE and GREEN cables again just in case, otherwise t can be the source component or the processor inside the TV.

The picture on the tv is blue red and green


http://www.retrevo.com/support/RCA-HD52W58-TVs-manual/id/402ci453/t/2/ Above is your user manual. www.electro-tech-online.com/.../36401d1261034747-rca-32-television-32v434t-need-help-repairing-atc010_training_manual-1-.pdf Above and below aew training manuals, these show you how they work, and how to isolate issues. www.scribd.com/.../RCA-Chassis-CTC203-TV-Trainning-Manual
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

RCA 32'' TV


Unfortunately, the Power Supply has spat the dummy out. It is giving enough power to light the LED but not enough to run the set. To replace it will probably cost more than buying a new set. But ask around your local repairers for a price before you make any decisions...

Blue red green lines around people images


this is caused by some kind of electrical interference. this can be caused by cd players,speakers, etc being too close to the tube. after you find the culprit and remove or move, unplug tv for about 10 mins, then plug back in

Try that and see if it helps. Stuck pixels are actually a slighty common problem.
