I have a Panasonic CT-31G30T television that is 10 years old.
When I turn the power off with the remote or the button on the front of the TV, the picture tube will sometimes stay brightly lit and not turn off. By turning the power off/on
a few times the picture tube may turn off sometimes; other times I have to unplug the TV. The problem is intermittent and not always there. Any idea what the problem is and what a ball park cost to fix might be?

Tv is old the tv CRT-(tv tube) it CRT Yoking circuitry not good as before.The tv deguassing coil in not eleminating all the interference of the tv functions anymore.Move the tv unit to the right or to left like about 3 or 4 inches either sides will help for this problems.
no there may be loose contact or dry solder in circuit board attached to tube..ie video driver section ..resolder all the solder joints cleanly...&also resolder the long ic ie chroma ic...u can find where the problem is by gently tapping the main board or video board by a tooth brush when tv is on. if the color changes by tapping u can get the loose contact..have a nice day
To turn off the "stuck" pip on a Panasonic tv without a remote, turn off the tv. Then hold down the "Action" button on the front of the tv and press the power button. This will activate a reset and self check of the systems and voila! The pesky pip screen will be gone! This is on an approximately 10 year old regular crt "CT-xxxxx" series tv.
it sounds like a DRY SOLDER somewherein the PC board where the POWER SUPPLY located , I suggest , if your HANDY with this procedure, Im sure you can get it fix , FIRST lets remove the back cover to get inside the TV ( if TV was recently turn ON , you need to unplug it and wait till the next day to do procedure , cause the picture tube acts like a BIG capacitor reserving electricity,cause we goona need to remove that big RED round rubber plug to the tube ) . to make it short , you need to remove the PC BOARD and look for any dry solder , and resolder it ,that will take care of this problem
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.
sounds like you either have a bad vertical deflection ic, or a bad resistor supply power to the ic. i'me not sure of the location, but panasonics usually put it in ic401.it is a ic with 10 to 16 pins all in a row. it will ne screwed to a small heatsinkthe making on the ic should start with laXXXX. x being numbers.
