Question about Panasonic PT-50DL54 50" Rear Projection HDTV-Ready Television

1 Answer

Flashing red led on PT-50DL54

In one of your answers you listed out what the number of red flashes mean. For my case I'm getting 6 flashing red lights then a short pause, then the cycle starts over again. You said 6 flashes equals 'Gc3fm-Iic'. Can you fill me in on what that stands for? I tried searching but nothing relevant comes back.

Thanks for your time.

I got various numbers of flashes also.
They all point to some components.
I simply open the back panel and vacuum.
I also use compressed air to blow at all the components and vacuum again.
Do not blow into the fan on the right as it will get the dust inside the lamp module.

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...


Time to get a new TV. I have similar problem. In my case, the set turns off, LED blinking green for about a minute or 2, then the set will turn on by itself. Something the LED started to blink yellow after blinking green and then shuts off. I can turn it back on. This happens 3 or 4 times in an hour. After that, the TV stays on for as many hours as I want until I shut it off.
And then the problem repeats everytime I turn it on from a cold start.
I have my eyes on the 50 inch Plasma from Panasonic. Bestbuy has one for 999.99.

My Panasonic PT-60Dl54J tv shut itself off and the power button is now flashing red 6 times. What has happened, how do I fix it?


This is straight from the service manual (I'm not sure what the problem is but it sounds serious):

8.2. Power LED Flashing timing table
When an abnormality has occurred, the protection circuit operate and cuts the power supply. At this time, the defective line can be
identified by the number of flashes (red) of the power led indication at the front of the unit.
NUMBER OF FLASHES CIRCUIT MICRO PIN
1 LOAD SHORTAGE 92
2 OVER VOLAGE 93
3 FAN SOS 94
4 MAIN 3.3V 88
5 LAMP DISABLE 61
6 GC3FM-IIC IIC
7 GC3FS-IIC IIC
8 GC3I-IIC IIC
9 COLOR WHEEL STOP 110

I have similar problems. I removed the back panel and use compressed air to blow out all the dust from all the components. Just remember not to blow into the main fan on the right as that is the one cooling the lamp. I don't know for sure if this is the only problem.
Dust built up caused heat built up on the components.

One flashing red light on xbox360 ( not red ring)


The specific type of hardware failure can be determined by a "hidden" error code
Turn the xbox 360 on, and wait till the 3 red lights are flashing.
Press and hold the sync up button (the small white one), while holding that button press the eject button.
The LEDs will now blink the first number in the code (as described below).
Release the eject button and press it again.
The LEDs will now blink the second number of the code.
Release the eject button and press it again.
The LEDs will now blink the third number of the code.
Release the eject button and press it again.
The LEDs will now blink the forth number of the code.
Release the eject button and press it again.
The LEDs will go back to the 3 red flashing lights.
You should be able to determine the difference between the 3 flashing lights and the error code lights by the rate in which they flash.
Here is how you interpret the LEDs to get the code number:
All four lights flashing - 0
One light flashing - 1
Two Lights flashing - 2
Three lights flashing - 3

Once you get this code, go to: http://forums.xbox-scene.com/index.php?showtopic=484726
To get the reason for the code.

What does a flashing red light mean>


Actually it depends. Which LED is it, lamp, timer, power? Depending which one it is, it will be the issue, if it's the on for the lamp, it's most probable that you may need to replace it sometime soon, if it's the timer, you need to reset the lamp timer, and if it's the power button, well you'll need to put attention to what other symptoms you can notice on the TV

remove back panel. blow out all the dust from all the components except the fan on the right.
Vacuum out all the dust.
Have you replaced the lamp? that would help too.
There are 2 small red lamp. One indicates HEAT problem. The other one is the LAMP indicator.

TV won't turn on


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
