Question about Televison & Video

1 Answer

My panasoinc tv pt-50dl54 will stop working and either displays the fixed red lamp light on the bottom of the tv or flashes 8 times red on the power button. From what I've read on the chat boards I may need to change my lamp and the Gc3i-Iic. What is the Gc3i-Iic??

Hi,
8 times blink shows problem with Ballast Supply and cause could be bad Lamp or ballast supply itself.

If you are interested to fix TV yourself then I would recommend to have Service Manual from Manual Zone. SM has schematics, exploded views and part number info.

GC3I-LIC is meaningless and it is not standard terminology in Panasonic or other electronics technical news that refers to some thing.

You can buy required Lamp from Part Store.

Thanks.

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.

The power will not turn on and the power LED is flashing red.


PT-50LD54 is an LCD rear projection TV with a consumable bulb that wears out normally after 2-5 years of use.

Most likely you need a bulb. That is first step in any troubleshooting for that tv. Check out Panasonic Gallery to identify lamp and replacement bulb.

Changing bulb involves removing the lamp assembly and replacing the bulb in the lamp assembly. Like doing a puzzle. Requires philips screwdriver, pliers and patience. Don't have jam on your fingers when you do it.

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.

Panasonic PT - 50DL54 Lamp problems


This can either be a problem with the ballast, or the power supply that powers the ballast. DLPs are usually easy to diagnose as they have a list of items that must happen for a successful boot sequence and it will pinpoint exactly where you trouble is at. I do suggest that you get a service manual for your set. I can post a link where you can get a proper service manual where they will email it to you if you would like. Let me know if I can assist you further.

Power Button Blinking Red


Talli,
The number of blinks, called error codes, is crucial in determining what's wrong with your unit.. In this case the color wheel is faulty and needs to be replaced. In that unit the color wheel assembly is Panasonic p/n# TXFEN01RP4S and is available from many sources for about $390.00 plus shipping.
There are some companies like Tri-State-Module that have taken-up rebuilding color wheel assemblies but I can't be certain that this is one of the brand/models they support. If you can have it rebuilt you might save about half the price of a new one...
For your edification in the future here are the blink codes for your Tv:
1 | Load Shortage
2 | Over Volage
3 | Fan Sos
4 | Main 3.3v
5 | Lamp Disable
6 | Gc3fm-Iic
7 | Gc3fs-Iic
8 | Gc3i-Iic
9 | Color Wheel Stop

If I can help any other way just let me know...
Good Luck!
Bill
