Double image


In all probability you need to have the convergence amplifiers replaced. A very common problem with all projection sets.

I am getting a double image on my 48 inch television how can i get rid of it? it is showing colors green and red on double image


Assuming that your TV is a rear-projection TV, then it sounds like the separate red, green & blue tubes aren't set correctly.

Each tube needs to be alligned exactly to produce the image on the screen. If any of the 3 are mis-alligned then the effect you describe is caused.

Somewhere in the menu settings, will be an option to set the Convergence. This option will allow you to set the allignment of all three tubes.

Older sets do not have this option, and need to be adjusted via controls on the main PCB.

48 inch toshiba with color alingment problem


Hello:

Thanks for this forum.

I have a Toshiba 48" rear projection TV which started to show red and green lines on the left side of the screen and have also started affecting the left-hand focus of the image shown on the screen. I have had this TV for 14 years and had a projection adjustment done once before.

Thank you in advance for your assistance.
