Question about Flat Panel Televisions
I have a 1 year old 50" Magnavox Plasma set (Model 50MF231D) that turns on for about 2 secs (no display) then turns itself off after about 3 secs. I turn it back on using either the remote or the side manual power and the green led stay's on for a few secs then goes into 4 red blinking LED lights.
Could this be a power supply problem? Any help and suggestions for fixing would be greatly appreciated............
The above fix, listed by Tom saved us!! We did as instructed and took off the back of our 50 inch Magnavox plasma tv. We were not sure what we were looking for so we googled capacitator (image) & there was a photo of a fried capacitator! Sure enough we noticed ours were "fried", we took out the board and went to an electronic supply store, bought the 2 capacitators ($2.00 each!!) and then found someone who did tv repair to sauter the new capacitators onto the board. (It is important someone who know how to sauter and recognizes polarity do do this for you) All in all we fixed this following the above instructions for $34.00 and our time. For a month we were told to spend hundreds getting a new power board!
Kudos to you Tom & thanks so much!!

I followed the solution e-mailed to me. My 50 in. phillips magnovox plasma had no sound or picture. I removed the back panel of the tv ( 55 screws) and removed the circuit board in the center of the tv. There are about 5 or 6 wire connections that you have to unplug, but they are all different in size so it's ot a problem when reconnecting. Take the circuit board to a tv repair shop. There are 2 capacitators side by side at the bottom center that were bulgeing. 3300ua 10 volt. I had them replaced by the repair shop while I waited. They had (1 ) 25 volt and (1) 16 volt available. The voltages do not have to match each other. The higher voltage is better. I put the tv back together and HURRAY!!! it works. I have been searching for a solution since last summer, Thanks to fixya.com my problem has been solved. It only cost me $35.00 total.
I thought the tv was going to the curb, thank god I didn't toss it. I hope this solutions works for the endless number of people who have posted this same prolem. GOOD LUCK!!!

OK - Skeptic here, have (had) this exact problem... Hit the power button...click-click - 3 seconds clickclick - red LED blinks 4-times. Opened the back and sure enough, at the bottom of the center "mother board" there were two capacitors with that "bulgy" look. I figured what the hell- I'll try it. A trip to Cables and Connectors in Newington, CT and $11 later-----FIXED!!!!!!!!!!!!!!!! It's easy and saved me about $800.. thank you!!!

To fix my 26" this worked.
The 32" and 50" are practically the same so it might work for you.

Solution #6 worked for me on my 3 yr old 50" Plasma. Not sure how long it will last though. I dread the thought of taking this TV from off of the wall. It's just too heavy for me. If not for that, I would have no problem trying fix #1.

We have been having the same problem with the TV not coming on and blinking 4 times in red. We shut the power off turn it on, shut it off, etc. This makes us mad! You pay a lot for a 50" TV and expect it to work. We have owned ours for 3 yrs. and about a month ago it started having this problem with the delay before it came on. Now we are going to try to take this 50" off the wall and replace the capacitors ourself. Maganvox told me the TV was too old and to contact a repair person. The repairman quoted me $125 just to come to my house and any parts were additional. So thank you all for your advice we are going to try to fix it ourself.

Used another poster's suggestion. Found two blown 3300uf 10v capacitors, replaced them at a cost of $1.40 each. TV working fine. LOVE you posters. Thanks so much!

I still haven't resolved this issue with this set. I've tried pushing the menu button on ititial power green LED and nothing. I've plugged it into its own power source separatley with a surge protector and nothing. I've turned it on an off repreatedly and nothing. As a matter of fact it was completely unplugged for over 5 months now and still the same issue. On Magnavox site they claim installing the software upgrade with alleiviate this problem but what use is that when you can't get the TV to stay on for more than a few secs. Or get the Menu to even appear LOL
It sits hanging 7 feet over my fireplace collecting dust. When I purchased this TV and had it mounted upon turning it on I needed to install that SW upgrade out of the box. Its the same SW upgrade I already DL onto the set. Calling Magnavox customer service is is like clapping with one hand. They won't even tell you what the fault codes are. It dusgust me to walk in my house an see this hunk of junk haning over the FP knowing I am still paying on it........... Its over a year old now but it literally stopped working 1 year after I purchased it.

I had the same problem with my 50" Magnavox plasma and used Guest's suggestion and it worked. I hope this is not a temporary solution and that we are not in for bigger problems. My plasma is not even 2 years old yet. Thank you, Guest, for your solution!
cris1114, my son repeatedly hit the menu button... did you try that? Hope yours is working again.

Had the same problem with my 14 mo. old Magnavox 50" plasma. Left the tv unplugged for two days, trying over and over for it to come on. Finally, Magnavox told us to push the menu button as the t.v. lighted green temporarily-surprise, it worked. I was ready to put it on the curb. Hope this helps.
