Hello,
please check your email. You should have received the service manual. Please check if there is a heating for G cathode (inside the picture tube neck there should be 3 light sources). If one is missing you should replace the picture tube.
Best regards,
Arpi

Hi; i have a 36 inched color television and it has a horizontal line going arcross the TV ,but it sounds like it is on but do not show a picture.Zenith Model# Sy3572DT and Serail# 781-4171582 I would like to purchase a part to replaced the old one could you help me.......
It's a Zenith remote, MBR 3440 is the model #, 124-202-01 is the part #. To program, press and hold PRG button until red light stays on, press TV,AUX etc, enter 3 digit code (www.xdiv.com) press Enter.
When you replace the entire board in a Zenith TV, you must make the adjustments to align the new chassis with the old picture tube. You must adjust the CRT bias and drives as well as the horizontal and vertical parameters. On the older boards there were controls on the main and CRT boards but on the newer boards the adjustments are made with the remote control after entering the service mode. Tune in the shopping channel QVC, set the color and contrast to minimum and lower the brightness until the picture is just visible. Set the CRT bias settings for a pure black and white image, then increase the brightness and contrast to get a very bright picture and if necessary adjust the drive settings so that the bright picture is pure black and white. Return the video settings to normal and then adjust the vertical and horizontal settings so that the info boxes on QVC are centered top, left and bottom. If you are not sure that you can do that right then have a qualified tech handle it for you.
