Panasonic PT-50DL54J DLP TV Flashing Light

Have a Panasonic PT-50DL54J DLP TV. Purchased in 2004. Power light flashes different codes (red). Have to unplug to get to reset. Some time ago lamp light also flashed, so replaced lamp. Lamp light no longer coming on but unit shuts down and power light flashes red. Have seen it flash 3, 4, 5, 6, 7 and 8 times since lamp was replaced. Looked online and can not find much info and manual is of no help.

    Same TV same problems, after unpluging and repluging multiple times can eventually get lamp to stay on. Thought it was the bulb but now being told are capacitors?

    I have similar problem. When I turn on the tv, after about 5 seconds, the on/off switch flashes red nine times--forever, I unplug it and try again. It may start, but I have two blinking images for about five minutes then all is well. This is only true with HDMI and Componect from the cable box. TV directly is ok. Even a second cable box soes the same, even watching a recorded show.

    When I turn on the TV, after about five sevonds. the on/off button blinks red nine times--forever. I unplug it and try again and it usually works, but then I get a double image on the screen that blinks for about five minutes and then clears up and all is fine. This only affects HDMI and Component input from my cable box. TV signal is ok. I have tried an new cable box--same results.

I had the same problems that most of you have been having, tv turning on and off, lights flashing in all different colors, having to unplug tv to reset and all of that good stuff. I noticed that most of the time this would happen once the tv would start to heat up, and I could hear the fan working a little harder. Well I am not an electrician but It was very simple to unscrew the lower bottom park of the tv, where the fan and most of the electronics sit, then I used an oxygen tank ( I work for a medical company ) to blow out all the dust in the tv, ( you can olso use the compressed air use for computer, but if grandma or grampa have some O2 laying around, it works really good, LOL. )and was very surpriced to see how dusty it was, then I removed the MAIN FAN ( you only need to remove three screws, however there's a box in fron of it, which you'll have to remove first in order to get to the fan ). this may sound a little complicated, but trust me it is not, once you have taken the fan off, clean it all the way around ( best to use a clean rag, the compressed air was not doing the job.
long story short, once I cleaned the fan and put it all back together. The TV still didn't work LOL, Just kidding, It has been working perfect for a little over a week.
If I can help in any other way, please e-mail me @ gsierra11@yahoo.com

hope this helps.

I have a Panasonic 42" plasma, only 18 months old...was working fine with no problems until about 10 days ago. TV would not power on, instead I would see 7 red flashing lights on the power button followed by a pause and then repeat 7 flashing lights. I called Panasonic, I knew I might be in trouble because I did not purchase an extended warranty and my one year warranty was expired. I think the Key to getting cooperation with customer service is to be extremely nice to whoever you talk to on the phone. The first person I talked to tried to get me set up with local tv repair-service people. I asked her to check to see if Panasonic knows about this problem and if I could speak to someone who might be able to help me get this repaired without spending my money even though the warranty was up. She told me to fax her the model number, serial number, my name, address and a brief description of the problem, which i did. Two hours later, they called me back and set me up with a technician to come to my home and fix the problem....at no charge! Two days later, my tv was fixed and it didnt cost me a penny! Apparently, Panasonic knows about this problem and they are fixing it on a case by case basis. If you are having this or a similar problem, call them and be extremely nice on the phone. Hopefully you will get the same good results as I did.

Absolutely, I took the back off and blew out all the dust, compressed air and a shop vac to catch the flying dust. I took both fans out and cleaned themmanually and put it back together and bingo, it has been running perfectly for more than 24 hours since.....

My tv cuts on but flashes red light 5 times and shuts off


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, in the "Search box at the top right of the display window of the Homepage" to get gathered related posts.
