I have an8 year old toshiba 57h81 projection tv. I am seeing pink and green double shadows around images. Any thoughts? Cost to fix? Thanks.


Have you tried the convergence procedure from the on screen menu? If the red and blue don't want to adjust when you do this then you most likely have bad convergence IC chips which can be replaced for about $50-75 in parts and $200+ in labor. If you have experience with electronics and soldering you can do this yourself. If not  leave it to a TV tech.

Your green gun in our tv is misagligned/out of focus. Your tv uses red, green and blue guns that layer in different shades and mix to create the different colors. Your green is a little off so the colors aren't mixing right which explains the green haze and the shadows. A tv repair man can fix this problem pretty easily and it isnt expenisve.

Blue shadow


If the blue shadow is convergence you should have an option for convergence adjustment via the remote control to converge the blue onto the green. If it doesnt move then its probaly a IC problem. What make and model set do you have?
