you will need to have the tv re converged to make the picture right call a repairman

the convergence tube is the faulty part in this case a new convergence tubes replacing is required.

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.

You need to take the Toshiba remote that came with the machine and go into a menu area that deals with convergence. Here's what the manual says:

This TV used 3 separate TV tubes, red, green, and blue. The R, G, and B images are pojected onto the screen wheree they converge to form a full-color picture. You can see a clear picture only when the three images converge correctly. Corvergence my drift over time, or if yo move the TV. I you can see clear images on your TV screen skip this procedure.

Make this adjustment only after the TV as been on for at least 30 minutes.

Press the TOUCH FOCUS (auto convergence) button on the front of the TV at the bottom.
The TV will enter into the convergence mode and adjust the converge automatically (that's what it says.)

TO ADJUST IT MANUALLY:

Press MENU, and the press < or > until the PICTURE menu appears.
Then press UP or DOWN to highlight CONVERGENCE.
Press < or > to display the Center Convergence menu

There's a lot more the book says, but, I can say from experience that you just go through the different sub areas of this menu and converge each color separately, and bingo, it's fixed.

Good luck.

Your convergence amp ICs are bad they need to be replaced.
