Check the 2 main interconnection cables (24pin and 26pin) rear of PDP and Tuner box. Make sure they are firmly connected. (Loose connection of 24pin will cause no power on symptom.)

My 15 month Celcus LCD423D913FHD tv will not turn on. The standby light is lit and will flicker but will not power up the tv. What is the likely problem?


Fault with its main board. Short circuited component/s at it. Contact any service technician; or the authorized service center. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. http://electronicshelponline.blogspot.com/ . In most cases, the main board might have to be replaced. If so, a software [firmware] update too might be necessary.

Lamp indicator flashes red 3 times every 5 secs.


Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.

Flashing RED lights in Panasonic TVs means a fatal error code. Unplug the TV, wait 1 minute and replug. If the LED still flashes it needs professional service.
