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

1 Answer

TV won't turn on

When I turn on my Panasonic PT-50DL54 TV, The power LED flashes green several times, then flashes red three times, pauses then flashes red three times. This sequences of three red flashes repeats over and over. The TV never does come on. I bought a shop manual that says there is a problem in the Fan SOS circuit. Any idea on how to narrow it down further.

Thanks

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

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.

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.

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.

The TV shutdown error code can help you with this problem. If the power led flashes green for 2 Min's then red. The Lamp led should flash red 1-2-3 or 4 time every 5 Min's. These are error codes that may point you in the right direction to you problem.

Those blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices.

If blinks continue without any pause, the main board is faulty.
Search the site by type in the "brand name" to your device, [Exclude the model number] in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.

Flashing red led on PT-50DL54


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.
