Electrlytic capacitor rated at 105 degrees

Your power supply is weak. If you think you can repair this I will tell you how. If you cannot do this,find someone who works electronics and share this repair. Two capacitors are bad. When pulling the back cover off, you may see one or two capacitors bulged. Even if they look good....replace these capacitors. The locations are numbered and, the capacitor having a value and temperature of 105 degrees.. Location of the first capacitor is 2074, value 25volts @ 2200 mf @ 105 degrees and will most certainly be bulged. The next capacitor may look fine....replace it. That capacitor location is 2066, value is 35 volts @ 1200mf @ 105 degrees. When you replace these, please be sure to get the polarity (positive leg and negative leg) of these capacitors seated correctly...this is a must. This will correct your TV. You will save lots of money, because you asked. Thanks for listening ..good luck...we will be here for your next repair.

I just fixed a similar problem on mine but the power light was flashing at the same time the screen was flashing. I made a video showing what part and how to replace it. I also added a link to the part I ordered. L5973D STMicroelectronics Mouser

Just fixed that exact problem on mine. I made a video on how I found the bad part and how to replace it. I also added a link to the replacement part below. L5973D STMicroelectronics Mouser

Hello
I actually don't understand what you mean by this question. About which capacitor do you mention about? For which section of your TV you want the capacitor? There are so many capacitors used in different sections, and have different capacitance values, and in idfferent voltage ratings. Without knowing the section, I can't give you advice to this post. Reply with details by Fixya please.

Although a capacitor may look good, it may be weak or bad. Here is what you will have to do. Replace capacitor (location) 2074 which is a 25 volt 2200Mf at 105 degrees. Replace capacitor (location) 2081 which is a 35 volt 1200 Mf at 105 degrees. And you should change capacitor 2066 which is a 16 volt 10Mf at 105 degrees. Please be careful with the last cap mentioned. You can easily tear the PCB trace if you are not extremely careful. This should bring your TV back to life. Thanks for asking and show a few hands of support!

I fixed it by replacing the two capacitors with 3300uf 25v instead of Magnavox's 3300uf 10v and a power swith that I ordered from http://www.encompassparts.com/. Also I did have a power supply put in from a repair place that cost $160.00. It is working perfect now and no blinking light.

Hello,

A full capacitor kit for the 37MF337 and 37MF321 models is available here:

http://www.ccl-la.com/catalog/product_info.php?cPath=21_77&products_id=216

The kit contains all 8 capacitors needed to rebuild the power supply board

The link below contains the original replacement remote control for your unit.

Sounds like you need to repair the power supply, don't fret, it can be really easy.  Here is a pair of youtube videos I made after following some advice on this website from other posters:
