The color on my 2003 rca 55 inch model number d52w20yxl is all of a sudden wavy and doubling

depends on the age and most importantly the model number of your set.

color wheel is getting ready to fail which is causing the color wheel to spin slower which cause the index speed to be off so the tints will be messed up.

You can try a new lamp, use the convergence feature to align the three lcds inside. If it doesn't work, you need service.

replace both of your STK iCs STK392-570s Call Mats 1-800-628-1118

My Phillips 55 inch televison comes on but no picture or sounds and the on and off button flashes.

Call a good TV Tech and have him replace the color wheel assembly.

first thing you do is to check if cold solder in main board. it is in chroma ic. there are many causes of this trouble. it might be also the tuner.

Is there an advanced convergence setup anywhere in the menu where the screen displays a grid? If so, you might want to get into that and move along the grid to each section that looks off. Adjust until the color falls behind the gridline, and move on to the next. It can be a time-consuming process, but should take care of your convergence issues.

need the model number of your set it sounds like the convergence ICs need replacing. Please reply to this same post with your model number and I will post the correct ICs for your model.

If its only one color out of alignment its the convergence board. If more than one color is out its the convergence power supply board. Please post the model number of your set and I will assist you with the problem. Please respond to this same post when replying.
