  • I have a magnavox model 37mf321d that did something very close to what you're describing.I researched the problem and found a 2200Uf at 25volts on the circuit board that the power cord plugs into blown up.I think it was C1074 but don't hold me to that number .It sets on the board by it's self not with a group of three other one's.I replaced it with a 2200Uf at 35 Volts and the TV works fine.I have been an electronics tech for around 36 years I went by a friend's TV shop and he told me it had another problem and was not worth fixing.It goes to show not everyone knows everything.I hope it's your problem because the part only costs about 50 cents.I found this fix on another sight and had nothing to lose after the TV shop had given it a death sentence.
  • The capacitor C2074 was bad on the power supply board in mine,I replaced it with a 2200Uf at35 volts.
  • Still looking for help?. I am looking for lcd screen for same tv. If you dont repair your, can you sell to me as is. I need lcd screen ( front screen) Thank you
  • I had the power light blinking problem also. The screen would blink along with the green light on the front but the TV would not come on. I replaced the 2074 capacitor with a 2200uf 35v capacitor from Radio Shack and all is well. Thanks for all of the help.
  • Thanks jwinfree!!!!! That answer was perfect and the part (2200uf 35v) cost two bucks at Radio Shack. If anyone else is out there who has this problem....UNLESS YOU KNOW WHAT YOU'RE DOING/ TAKE IT TO A TV GUY WHO CAN DO IT FOR YOU. Tell him you know what the problem is and see if he can do it.(Maybe under $150.00 for his time) I am 100% sure that there is a factory defect with this model and MAGNAVOX ain't admittin' it.(or doesn't know it) You MUST be good with a soldering gun to do this job otherwise you're asking for it.
  • First off, thanks for the fix! My TV had this problem for about a month and then the light finally went out totally. My Radio Shack only had axial(leads out each end) capacitor for that rating (2200 uF), but I was able to make it work since that area of the circuit board has plenty of clearance. The Radial cap would have been better, so you may want to call ahead and make sure your RS has the radial form factor.
  • I'm glad for those of you who can identify and change the suspect caps.However,please remember those overpriced cheap Chinese caps your buying at Radio Shack are no better than the ones that blew up in your power supply in the first place. I really would highly recommend Panasonic fc series. These can be ordered from Digikey for a good price and they ship fast.You have choices of different sizes with the same uf value,low esr,105c high temp, and anywhere from 2000-5000 hours before they dry up. Just trying to help out guys.I use thse in my lcd tv's,dvd players,stereo equipment etc....they are simply excellent caps for power supplies.Hope this helps and good luck.
