Unplug it from the wall, wait 2 minutes and plug it back in. if problem still exists, its probably the main pcb.

An earlier post of the smaller model of this with the same problem said to remove the metal cover over the power supply.
I have the 26MF231D and it worked great afterward (even though you can't mount it)
Here is how you remove the cover.

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/

Right now your TV is in " Protection Mode " because of a failed part inside. The blinking red light is a error trouble code. Only someone with the actual Service Manual for the TV will know what the code means. Most likely the TV has a power supply related problem. It's possible that it maybe a bad capacitor or transformer on the power supply board. The most common board to go bad is the Backlight Inverter Board. It what supplies power to the screen. But, I can't say it's 100% the problem because I can't actually look at the tv over the internet. I can only make guesses with the symptoms.
You have a few choices:
1. You can try leaving the TV unplugged for 30 - 45 minutes so the TV can discharge and reset itself.
2. If by chance the TV is still under warranty, go that route.
3. If you have some electronic experience, if you can find and purchase a Service Manual over the internet; It will help you diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you red light blinking codes, circuit diagrams, test points, and part# lists.Usually, cost under $20. And most cases the new part cost less than $15.
4. Pay a TV shop to do the repairs. It maybe costly, but get an estimate of how much they will charge. That way you can decide if it worth repairing or replacing the whole TV.
I hope I shed some light on the subject for you.

Yes, he means 2200 microfarret (called uf from here on out). Another important concern when buying a replacement is the voltage. You need to get something that is at least 25v. I recommend a 35v or better. Another notable point is that this may not always fix the problem. As with mine, there was also a 1200uf (microfarret) 35v capacitor that was blown. You can tell this because they bulge at the top. I have both of these caps (2200uf 35v and 1200uf 35v) on order and they will be here tomorrow. If I do not post back here then they fixed the issue for me. I suspect that this will resolve the problem. Look for bulges on top of the caps. This is an indication that they are blown. Most all of you experiancing these symptoms will see the 2200uf cap bulging but you may also see others bulging too. If you do then you need to replace those too. No electrolitic capacitor should be bulging at the top so if its bulging its bad, and if its bad then your tv will definitely not work. Have fun.
