4 blinks What is fix for that?

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
upgrade...go
here...http://www.m4c.magnavox.com/cgi-bin/dcbint/cpindex.pl?scy=US&slg=AEN&cat=FLAT_TV_CA&sct=PLASMA_EXTRA_LARGE_GT43_SU&grp=TV_GR&session=20090902212032_75.92.128.105&ctn=50MF231D/37&mid=Link_Software&hlt=Link_Software....and
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 protected]). 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.
Good luck.

The problem you are talking about is related to the power supply board of the tv. Look for faulty capacitors, especially the ones rated 3300uF. See if they are cracked or bulged at the top. You will have to de-solder the old ones and solder the new ones in. If you do not want to go for a component level repair, you can simply swap out the board. I can find you a replacement for about 100$
