SOURCE: red blinking light
The red light blibking 6 times indicates that the power supply board has a defective or damaged area. I know this because i had the same problem...bought a damaged tv for parts and replaced the power supply board as the tv would not turn on...wokrs like a charm now.

Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.
Magnavox Plasma TV. Model # 50MF2310/37 screen has no picture. There is no sound, TV comes on and then after a few seconds clicks and screen remains blank.
On the main power circuit board to Capacitors are prone to failure from over load. The caps are 3300uf 10v 105+c capacitors located to the left of the AC power input.
Magnavox will refer you to a service center. They will advise $$$ for an inspection. They will also want to charge upwards of 500$ to replace the entire board.
1. Unplug your TV
2. Disconnect all connections from your TV
3. With assistance lay your TV on its face on a non-scratching service
4. Remove the back panel screws.
5. Lift back panel off
6. The central board is your main power board.
7. Remove all wire harnesses from the main board.
8. Remove all screws that are holding the main board in place.
9. Lift the main board out and carefully place it into a non electromagnetic pouch.
10. Take the board to a Circuit Board repair shop.
11. Have them replace the the above mentioned Caps.
12. Re-install the board in your TV.
NOTE: Replace the caps with 3300uf 16v 105+ high temp caps(preferrably Japanese caps)
This fix cost me 80$ and my time to search for other who had the same issue. Try searching for Magnavox Plasma TV. Model # 50MF2310/37 bad circuit board or Magnavox Plasma TV bad capacitors or Magnavox Plasma TV bad ciruit board.
Hope this all help, Magnavox is should take ownership for this problem and recall any tv's that have these caps in them. The worst part about this is that teh **** from the repair center that was paid 100$ to check the TV, stripped out the screw holes and damaged the case for the TV.
Portland Laptop Repair was awesome. They repaired the board and it looked like new. Check them out at http://www.laptopportland.com/

Here is the solution. I have this same tv and the same thing happened to it. I spent a lot of time searching on the internet for a fix. I finally came across one. Basically there are two capacitors on the main power board in the tv that go bad. You can tell because the tops of them bulge. I bought new ones on the internet for $6 delivered. I figured it was worth $6 to try this solution that I had found. If it did not work I was only out $6. I am not a professional repairman or anything either. I do know how to take things apart and have done some basic soldering in the past. So I ordered the capacitors specified below and took my tv apart. Just as the instructions said I had two capacitors right next to each other that were bulged. I carefully removed the board from the tv and then got out my soldering iron. I removed the two capacitors after watching some how to videos on youtube. Then I replaced them with the new ones and put everything back together. Turned on the tv and it has been perfect since. That was about 4 months ago. People that tell you that you need a new board are technically correct as this would fix your problem. But this is what is wrong with the board. It really is a $6 fix.These two capacitors just need to be replaced. Below are the exact instructions that I followed. If you have questions you can email me at firstname.lastname@example.org
HERE IS THE FIX:
1. Unplug your power supply cord.
2. Remove back panel on your HD.
3. Look for capacitors that have a bubbled or slightly raised and rounded top. This indicates the capacitors have overheated or leaked and need replaced. The normal look is a flat surface with no raised feature at all. (I had two bad capacitors that were side-by-side and identical: 3300uf 10v. Also, they should be located on the power supply board. My power supply board was in the middle of my 50" plasma.)
4. Go to an electronics store or Radio Shack and see if they carry your capacitor type and size and replace them yourself if you are comfortable with removing the capacitors and soldering new ones to the power supply board. The capacitors will cost you $2.00 each or less.
5. I was not comfortable replacing the capacitors myself so I removed the power supply board by removing the screws and unplugging several wire connections. This was not difficult at all. I then brought the power supply board to a local electronics shop that did repairs on HDTVs and simply asked them to solder the two new capacitors onto the power supply board. They did it for FREE while I waited and it only took about 10 minutes.
6. I replaced the power supply board and back panel of TV and it worked!!!
Some people on this sight suggested replacing the capacitors with some that have higher temperature ratings. Based on that advice, I wanted to replace my two that were bad (3300uf 10v) with two rated at 4700uf 35v, but my electronics guy suggested against it. Instead, I replaced mine with 3300uf 16v, with the only difference from the original parts being the higher voltage (16v instead of 10v). I figure if the problem occurs again, I now know I can get it fixed for less than $5.00. Philips - Magnavox should be ashamed for such poor customer service and not telling people about this simple fix. When I called their customer service support number I was simply directed to a repair place -- two hours away!!!

OK I have just taken care of both of these problems and now I want to
share it with you DIYer's. As for the blinking red it is a software
download the software to your PC. Then unzip it to a USB flash drive.
Power off your TV. Stick the flash drive into your TV's USB slot, found
on the left side, facing the TV. Power it up and let it do it's trick.
Pull out the flash drive when instructed. That's it.
Now for the power problem. I noticed that my TV was taking longer and longer to fire up. Once on it worked great. Well this morning it didn't come on. I heard the usual relay click then a few seconds later...two more clicks and nothing. The green LED stays lite but it's dead in the water. So I started surfing the web for common problems found with this particular model. I came upon this forum and saw something about a couple of capacitors. So I decided to look into it. I purchased the service manual online for around $8.00 at https://www.completeservicemanuals.com/philips/magnavox/plasma-television/50mf231d/37-service-manual/prod_677.html. Not that I thought I would need it but it doesn't hurt to have it. So I took my TV off the wall and placed it on my bed face down. Be very careful because this TV is heavy!!! You will need to remove the stand or wall mounts first. Then there are 44 screws holding on the back, 32 long and 13 short. Pull the back off from the top of the TV first, set it off to the side. Now your looking at the workings...in the center is the power supply board. Oh yea please make sure you unplugged from the wall. There are 8 wire connectors to the board, 5 of them come off by squeezing the clip on the back, the other 3 just pull out. OK, there are 8 screws holding down the board to the chassis. Before lifting the board, locate the capacitors first. If the top of the TV is away from you and the bottom is near your knees (assuming it's on your bed) look at the center bottom of the power board. Locate two capacitors that are identical and side by side. Their values are 3300uf 10V. I found that these two buggers were raised on top, kind of bubbled. (if needed I have pictures of the power board, email email@example.com). I picked the replacements up at a local electronics store for less than $5. I simply replaced them and reassembled the TV. It works killer just like when it was new.

Your problem is caused by a power supply issue it sounds like a capacitor is leaking or has vented and will need to be replaced if your comfortable you could check the power board for a can shaped electroletic cap that has vented it will be puffed up on the top the value is printed on the side you can or have someone replace it that should take care of your problem the power board is the one where the AC cord plugs to or leads to
