LCD TV I have had my tv for 2 years and one day the sceen started flashing on and off, then it just stayed off. It has power. Could it be the bulb?

Sounds like the T-Con board is toast. You can get a replacement at : TV Parts Universal TV Stands DLP Chips ShopJimmy

Hi Cool,
Please disconnect the bulbs number one and solder a 4200pf/2kv capacitor in its place. See if the set works. Do the same for all the bulbs till you find the defective one. With the defective bulb replaced with 4200pf capacitor set will not power off. If this works and the light on the screen is sufficient, you can leave the capacitor soldered there. I hope it helps.
Good luck.

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.

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.

you need to call acer you have a bad lcd sceen. i juct di one the sceen was fault.

I have a 56" model that I have had a similar problem. My bulb burned out in <90 days. Warranty was 90 days on the bulb itself. When the TV picture goes out, the indicator LEDS blink on and off.

Here is what you have to determine:

1) First cover the left LED with a piece of paper so that you can't see it blinking. I don't know if your layout is the same as my TV. You may have to switch the paper blocking the LED.

2) Pay attention to the other LED and READ its' flashing code. In my case, the code was 2-3. It would flash 2 times, pause briefly, then flash 3 times. This meant code 23. That indicated the bulb was burned out.

3) If you look in the manual, It does have a code list of some sorts to tell you of the codes and their meanings. Hope this helps.
