My magnavox tv worked good turn it off later tryed to turn it on and it wont i notice the green light on the power button wasn't on
Fault with the main power supply regulator section. Either it will be on a separate board, or on the part of its main board. Check and replace damaged component/s at its main power regulator [SMPS] section circuit. Contact any service technician. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts.
It will be best to replace the power supply regulator board as card basis rather than making "Surgery" to it; which usually will make loss for both money and time. 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.

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!
