When powering on our Magnavox 13" tv, the screen is bluish in color, shows the channel, has about 5-8 lines across the top and then shuts off. Pressing the power button does nothing unless you unplug it and replug it, then it happens again.
Try to measure the color signals from your 3 color amplifier(s) on the CRT board, with an osciloscoop, and check if they all apear to have the same shape. If 1 of them is different, you might want to check that color circuit!
No power to magnavox tv model# RS2756 C402 chassis 28Y100-00AA. No lights, noise, etc. Dead.
Is the main fuse blown? If yes, there's a problem in the primairy side of the power supply. If no, check the following: 1) Do you have 300/160V over the main capacitor. 2) Is the primairy-power-transitor "working"?
