The power supply must be checked for any possible damage in the unit. See the power main filter capacitors for fault. If Ok check on the main board, look for short in the main board or a possible dry joints in the convergence IC's. If you find them suspicious change.
Disconnection of the +B should bring up the voltage . Hence the concerned circuit /IC can be centered out.
The microcontroller must switch and cut off in such an error. If blings it still present, possible it needs a reset. Try to press and hold Menu/input while switching power on.-Try the rest code if present in the manual.

The blue lite comes on and then starts blinking. nothing happens. when I turn off the lamp light comes on. Has a new lamp


whats the model number of the tv? Have you checked the user manual to check to see how to reset the tv after replacing the lamp? Usually there is a sequence to perform after replacing the lamp and most of th etime you have to have the original remote to perform it - i'd check that first..

thanks,

Tv wont come on


You may have a Lamp fan that is not turning. You can verify this shining a flashlight in the Fan Exhaust housing and see if it turns when you turn the set on.

Tv not turning on


I also have this model. A few months ago, when I turned on the tv, it told me my lamp was in need of replacement. just yesterday, my tv did the same as you....the blue light flashed and then the lamp light kept flickering. All I can say is your lamp needs to be replaced.

Tv doesnt turn on after replacing lamp??


Just took a look at the manual.
This information is in the troubleshooting section of appendix H in the owners manual.

12. Lamp indicator light is a flashing yellow. Lamp cover door is open or lamp cartridge is not secure. See AppendixH for lamp replacement information.

Appendix H is a bunch of graphics. that you'll need to see to understand. i can't paste it all here.

Panasonic PT-53WX42 - When I turn the TV on, the red light comes on but, no sound or picture.


Does the light blink? If it is blinking a 3 code, the IC's need to be replaced. Those three lamps as you called them are not lamps, they are the three picture tubes.
