Question about Toymax Magnavox 37MF337B 37 in. LCD TV
I saw that you tried to resolve a problem 32MF231D that had power issues earlier and was wondering if mine would be the same solution. Here's the deal - when the TV is plugged in, all that happens is a blinking green light. You cant turn it on. The remote makes the green light blink really fast so it is picking it up. When you hit the power button, you hear a full click and then another click that doesn't make it all the way. I have it apart and I saw 2 green LEDs light up for each click on a board in plain view that has the AV inputs on it to the right of the power supply. Nothing looks fried. Same problem. There was a time where I could turn on all components that are plugged in to it (Game, DVD, Sat, etc.), press channel or volume, and eventually (5-10min) it would come up. Now nothing.
I had this problem, but saw other places that it was a cheesy capacitor on the power supply circuit board causing this. I opened it up and took the power supply board out and it was obvious which capacitor was bad...top was bulging and had black stuff on it. It was rated 2200 uF @ 25V...got a new one @ Radio Shack that was 2200 uF @ 35v. Soldered it in (I stink @ soldering, but gave it a shot and it was EZ). Watching the first weekend of college football w/o waiting on a flashing green light for up to an hour so the TV would start! I'm going to try to find the other websites that directed me to this to say THANK YOU...BTW my brother used to have fits with several Magnovox TV's and thier power supplies back in the old tube style TV days. I thought I didn't need to worry about this with an HD flatscreen, but was wrong. I will think twice before buying a Phillips/Magnavox/Funai/whatever else they are again. They have a long list of complaints and I believe a class action lawsuit to refer to about this problem. They should have stepped up and done something!

Our 37" Magnavox was having the same issues posted here. Blinking light. My husband and I FIXED it for only $5 and an hour of our time. People stop complaining and give it a try. What do you have to loose? It was a very easy fix.You will need to remove the old capacitor, solder the two wires on the new one in then put it all back together. That is it. If you feel unsure about where to put parts back, take pictures for review. I used the same 2200 @ 35v capacitor like the person that posted the pics. Very helpful by the way.

I had the same problem on my MAGNAVOX 37MF337B/37. At first flashing green light and would take many tries to turn on, then finally nothing. I followed the advice of others on this list and ordered a replacement power supply module. Part cost about $110 and was easy to install. The set appears to function perfectly now.

I had the bulging capacitor as well on my Magnavox 37 inch. I replaced it with another 2200 mF 25v and no luck. No other evidence of problems on the board, ie no other bulging capacitors. It should also be mentioned that the capacitors are polarized and have to replaced with the leads aligned with the correct positive and negative receptacle holes. I blew up my first replacement capacitor because I didn't know this. Any other ideas what this could be? I have the flashing green light.
