Getting red, blue and green halos around images


I had a similar problem with red halos around images on my Hitachi rear projection TV. The problem was that the red convergence chip burned out. I replaced that and that fixed the problem. I found several forum posts on similar symptoms and fixes for Sony rear projection TVs by searching for "Sony rear projection convergence problem." Likely you've already tried the auto-convergence function for your set, if it has that.

Picture shadow on rear projection Sony big screen TV


You have 2 distinct problems that should be addressed separately. Please repost the Samsung problem. I will address the Sony problem here.

If the "shadow" makes the picture seem somewhat of a 3D one, the problem is with the convergence circuit. This could be as simple as bad connections on the pins of the convergence ICs or defective ICs. If you can solder and would like to attempt the repair, update this and I'll provide more details and instructions.

Philips 55 inch hdtv rear projector





Projection TV tubes have a liquid coolant that is used to keep them from overheating. After many years the coolant in the blue and green tubes will become cloudy and cause the screen to look dull, red/orange, etc. You may even see halos around images. 

What you will need to do is replace the coolant and clean the crt. You can get a repair kit from www.TvRepairKits.com that includes replacement coolant, photos. instructions, etc.

Panasonic PT-51HX41 rear projection tv showing shadow/double images.


Unplug the TV from the ac wall outlet for about 4 minutes then plug it back in and turn it on. If it still has a double image then tell me if it's affecting the menu screen from the TV (not the cable menu). And is the double image in red and blue?
