Question about RCA Televison & Video
This sounds like a problem with "convergence" of the TV. The convergence circuitry performs the electronic aiming of the Red, Blue & Green projectors. Typical
convergence problems result in distorted images on the screen such as: double or triple images on part or all
of the screen, wavy lines, curled edges, excessive red, green or blue
color or tint, etc. Sometimes, convergence issues can be corrected in a
menu setting of the TV that has to do with "Picture Settings" or
If the colors are out of alignment a great deal or went out "all of a sudden" it will probably not be repairable via the menu adjustment described above - but is certainly worth trying.
If it does not straighten out with the menu adjustment, it will probably require replacement of the convergence integrated circuit(s) chips located in the TV. This was a "big ticket" repair years ago, but can be done sometimes for as little as $40 in parts. Don't let the low price fool you though.. It can easily take several hours (or more) to access, remove & replace the components and reassemble the TV. Soldering skills are a must - and I'm not talking about soldering plumbing pipes here either. These are delicate electronic parts and need a 15 - 30 watt soldering iron and de-soldering braid or "solder ******" and LOTS of patience to perform CORRECTLY. As such, it is "not a DIY project" unless you're willing to risk turning your TV into a large floor model paper weight. If you decide to attempt this repair, you should google your TV brand and model along with the term "convergence". Parts, costs and procedures vary by TV. Unplug the TV for a day or so before starting the work to let capacitors discharge fully - just to be safe. Lastly, if you're going to attempt the repair - don't forget to purchase silicone heat sink compound - it is an absolute *must*!
