I have a Panasonic PT-50DL54 50" rear projection tv. My tv screen won't come on but the fans will. The power led light flashes green like normal but than starts to flash fast for about a minute than the red light cuts on like it's off. I have replaced the lamp three times in the last six years so I know if the lamp unit was bad and it's not. Can you help?

Replace the lamp.

Check ur tv fan,if ur cooling fan are runnig,before all these LED lights are flashing.If not that ur tv problems.All these LED lights are flashing the tv making alots of clinking noises too like it trying turn itself on?Yes,than the tv board that called the Ballast board it is dead too,must be replace also.This tv Ballast board only job are to help to ignite the tv projection lamp only and keeping it on and running.

Tv making and have clicking sounds as tv shutdown as lights flashes?Yes.The board that call the Ballast board might be dying and dead soon.This Ballast board job responsible only are to ingnite the tv projection lamp only.

most likely a transformer in your stand by power gas blown, best to replace the power board

Hi,

The most common cause of Panasonic Rear Projection LCD TVs not starting is bulb failure. The PT-60LC13 users manual gives some help in translating the LEDs on the front of the TV.

If the TV worked normally for a period of time (months or years) and won't start, the most likely cause is bulb failure. There is no way to measure the bulb, sometimes the bulb is visibly damaged when it fails. Remove the Lamp Assembly and look at the bulb.

If there was an On-Screen Lamp Replace warning and TV won't start, bulb has failed.

The first step with all Panasonic Rear Projection TV "No Picture" problems is bulb replacement. If that does not remedy the problem, get a technician, there are no user serviceable parts. Guessing if the ballast, power supply, controller board or optical engine is faulty is not practical.

The Panasonic Lamp Gallery shows all Panasonic models and Lamp Numbers. There is also a link to Panasonic DIY bulb and lamp replacement.

Ur tv LED light indicator "LAMP"flashes?Then the projection bulb life is over must be change.This tv been watching the tv at least 4 or 5 hours a day,the last 3 years?The projection bulb only last about 1500 hours.

Check the Lamp if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 2X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.
Check the ballast if no picture, audio may be present. Screen is completely dark. Lamp LED flashes 3X every 5 seconds, Power LED flashes GREEN for 140 seconds then flashes RED.

Hi friend,,,,,,
it is an indication of an error code ,,,,,,normally 6 blinking code refers to an power set up problem,see incoming voltage with an multimeter.......

thank u,,,,,,,,

problem is fan stoppage this is probable caused by excessive
dust in fan take off back and locate visually the cooling fans in unit
use canned air to remove dust until fan moves freely. if all fans
are clean maybe one fan is not giving rotation detect signal
look at voltage on white or yellow wire from fan s/b 5v then 0v
when fan rotates if one stays at 5v replace it

ok you have defective power supply in hotside section! maybe they have abnormal oscillation!
