Panasonic PT - 50DL54 Lamp problems

My TV would not turn on and the lamp light would flash at times (not every time I would try to turn the tv on, but most times.) I bought a new lamp,took apart the housing, wired it in, reconnected and re-screwed everything back into the same place it was when I took it apart. The same thing is still happening to my tv. I try to turn it on, it flashes, then the lamp light comes on. Hope you can help :-)

    That link would be very helpful!! It is kind of exciting being able to diagnose the issue when the only thing I have ever fixed is a curtain rod!! Thanks again for your help.

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.

I've replaced the lamp for my panasonic 50DL54J. When i try to turn the tv on, the power button blinks green, then turns yellow, then the lamp red light blinks..and turns off. Can you please help?


some times when the lamp is not sitting in place it will give you this problem. removed the lamp, put it back and make sure it goes all the way in. close the door and attach screws if any. remember if the lamp door is not close, your tv will not turn on. had the same problem until i reseted the lamp in place. good luck

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.

Picture goes away on my DLP TV


that is an overheating problem. With the TV unpluged clean and or vacuum the internal tubes. Not the lamp though. Do not touch the lamp as any oils on your hands will cause a hot spot and the expensive lamp will fail.

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.
