Even though you can make it right, it will cost around an amount equal to the cost of a new board; including the cost of (spare parts + service charge) More to say, most of the spare parts to it will be difficult to get from open electronic spare part market. This is true to most of the flat panel TV power supply boards; irrespective of its brand and screen size.

No video

aside from checking connections to see they are right, if using a box remove it and the set from power for a while and then power back to see if it will help or not.

Can i use a 1000uf

Absolutely NO! Although it may be close, you will find a poor startup just as if the set was still bad. The capacitor you need is of course a 25 volt 1200MF. In this case a 35 volt 1200MF will work. I would suggest in this case a next up voltage with the correct MF. In this case the best sub is the 35 volt 1200MF. Check out Matelectronics.com. or MCM Electronics.com or Mouser Electronics .com. If you have a local Electronic supply store they may have what you need. I do not believe you will find it at Radio Shack. Thanks for asking and show a few hands of support!

Magnavox 37MF331D 37 in. LCD TV

I had the same problem with a Magnavox LCD TV. It would not turn on and the light on the external PSU flashed. I found a replacement 12V 5A power supply on EBAY. It brought the set back to life.

I lost the picture on my 37

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
