I have a magnavox tv model 26MD255V

SOURCE: 50" Magnavox Plasma TV will not turn on - Red LED blinking 4x

When you have the red light that blinks four times on the 50" Magnavox Plasma Model 50MF231D/37, you should look for the capacitors on the power board in the center of the of the TV. Look for two 3300uf, 10V, 105c capacitors that have a build up of pressure that has caused the top of the capacitor to look rounded instead of the flat top that will be on all of the other capacitors. Changing these two capacitors fixed the problem of the TV not coming on.
I had more trouble finding the capacitors than changing them. I could not find them locally so I went to an on-line electronics supply store where they were $1.65 each and $8.99 to ship.

Here is the solution. For less that 100$ your Magnavox Plasma TV. Model # 50MF2310/37 will be running like a champ.

Issue:

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.

Cause:

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.

Service:

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.

Solution:

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 [email protected]



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!!!

You would be better off to have a shop check it out. Try unplugging it for a while just to reset everything.
