Line across middle of screen.


The line of color is due to a failure in the vertical circuit. The main suspects are the vertical Ic AN15525A and/or capacitor c308 220uf@35volts
If you have the capacity to do so, you should check the other electrolytic capacitors in the vertical circuit which are USUALLY located near the vertical IC in most cases
you can purchase the part at

Horizontal white lines across top of TV screen


Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

Panasonic CT-27D30B


Put a voltmeter on the vertical I.C .
pin 1 should be 12Vdc
pin 2 should be 24Vdc
from those two inputs, it should be generating at least 50V on pin 13.
If those are not present, trace the power back to its source in the flyback circuit, where a resistor or diode has blown.
If present, check its output on pin 12 and if there, trace through the vertical output circuit.
If not, it may not be getting a trigger pulse from the main video chip.
Hope Ya Fix It!

No picture no sound nothing


We had a TV repairman look at our 3 year old (Oct 2004) Panasonic CT-32HXC14J FLAT SCREEN TV. It suddenly stopped working and appeared to have no power getting to it. It was a high voltage supply or transformer that was bad and has to be replaced - estimated cost is around $400. In a year we will also need to spend around $125 for a digital converter box. We went for the repair since that is still cheaper than a $1,000 plus equivalent size LCD or plasma.

Our old tube tv was still working after 15+ years. They aren't making them like they used to. Way to go Panasonic.

Buzzing sound, no picture on my Panasonic TV


You might have a short causing the set not to start. Probably in the horizontal/high voltage circuit. The buzzing sound that you're hearing is the power supply overloaded. Stargazer
