My 52 inch RCA projection tv has a blue line around everything white


The convergence needs correction. If its not able to be cleared up by running the auto convergence feature in the setu menu then you will need to repair the convergence. You can get free technical assistance and parts foor your RCA at www.tvrepairworld.com they are RCA experts with that chassis

Sounds like this is an issue with the convergence of the television. These don't have a software convergence setting so you will need to find a vendor to replace the convergence amplifier or purchase a new TV, it may be more cost effective than repairing this one.

You have a problem with convergence and all you may need to do is replace a fuse. Look up convergence for your tv model and hopefully you will get an answer as to where the fuse is located and how to replace it. Very common for RCA tv's

My RCA projection TV - the picture only shows red green and yellow and the picture is distorted almost concaved. It overlaps and nothing is clear. All 3 bulbs seem to be working. No idea what is wrong.


Sounds like convergence problems. This TV may not have the standard "STK.." modules. These sets are bad to lose voltage feeding the convergence amplifiers.

The picture on my tv is warped


Hello jbvail86,

This problem you are having is a convergence problem. The convergence amplifiers are malfunctioning. Both Amplifiers need to be replaced. You will need a schematic, and a multimeter to check the voltages on the pins of the convergence amp ICs. Once you find that the ICs are bad you will need to de-solder them and the biasing resistors and replace the ICs and resistors. The schematic will help you find the proper resistor values.

I hope this helps

Thank you,

19, signal 19, 19, what is it trying to tell me?????


The only error code 19 for the ITC222 chassis listed from RCA/Thomson for 19 is invalid chassis detected. Which doesnt make sense unless you have replaced a PCB with a wrong part number.

Convergence


Hello,
This is a sign that the amplifiers are on the verge of going out since it is able to exert partial control over the CRTs. I would suggest that you try manual convergence, follow the direction in the schematic diagram on how to do this. If this does not work then I would suggest either changing out the convergence amplifiers and all of  their biasing resistors, or having a qualified TV repair shop do the job for you.
I hope this helps,
Thank you,
