The TV will will not turn on with either the remote or front panel. AC power is getting to the power supply and I checked the fuse. The fuse is good. I'm not sure where or what to check on the power supply for proper operation. Is it cheaper to get a whole new main board or fix the individual component?

Re: No power and won't turn on
If you know how to use the multimeter is to get a service manual. Try http://www.servicemanuals.net Then troubleshoot the power supply and the sweep supplys. In most cases if you had to replace a complete board,unless you get it from an exchange company that repairs boards such as http://www.ptscorp.com, then it exceeds the cost of a new set. Good Luck

Replace the power supply board the blinking power indicator is usually indicating the power supply needs replacement or repair. You can get the replacement power supply boards from www.tvcircuitboards.com
Hello Chech whether AC power get into the power supply regulator section. Just open your tV, and check it. There is a fuse [ glass cartridge type] on the power supply section. Check whether it has blown up or not. If blown up, make sure that there is some shorted components at the power supply section check it.
TV won't turn on • Press the TV button. Make sure the TV is plugged in.• Check the wall receptacle (or extension cord) to make sure it is "live" by plugging in something else.• Something might be wrong with your remote control. Press the POWER button on the front of the TV. If the TV turns on, check the remote control solutions on page 26.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).Buttons don't work • If you're using the remote control, press the TV button first to make sure the remote is in TV mode.• The front panel controls may be locked (disabled). Use the remote control to unlock the front panel controls by selecting the Lock Fr. Panel in the PARENTAL CONTROL menu and press OK (box won't have check mark).• Unplug the TV for two minutes and then plug it back in. Turn the TV on and try again.TV turns off unexpectedly • Sleep timer might have been activated. Go to page 24 for instructions.• KidPass might have been activated. Go to page 21 for instructions.• Wake-Up timer turned on the TV and no remote or front panel buttons were pressed for two hours.• Electronic protection circuit may have been activated because of a power surge. Wait 30 seconds and then turn on again. If this happens frequently, the voltage in your house may be abnormally high or low. • Unplug TV. Wait five minutes. Plug it in again.
If there is no power indicator LED lights up when the set is sitched ON, the power regulator section inside your TV is faulty. There is a fuse [glass cartridge type]; on the power regulator board. If this fuse blows OFF the set won't switvh ON of the front power light won't light up. Check this fuse first. You can locate it at its power switching regulator board inside, where the AC power goes straight to it after a filternig circuit. If the fuse is blown out, replace ti with same rating. It ratings will be marked either on its edge rims of on its body by colour code lines. Replace the the fuse; if it has blown out, and switch ON the TV. if the replaced fuse also gets failed, do not put any fuse after, the power supply section has some short with it. It is best to replace the power supply board as a card absis; rather than making "surgery" to it. Some components in it will be very difficult to get too. You can buy a new power board from /Vizio Authorised Service Center at your town. OK.
There are at least two power supplies in any set with remote capabilities; one is on any time the set is plugged into AC and is supplying that indicator and the receiving circuit of the remote, otherwise it wouldn't turn on under normal conditions.
The second power supply produces the needed service voltages used when the set is in use.
This second supply is a common failure in many sets and it is generally traceable to poor design and the use of low-quality components of a certain type.
Vizio may have a repair or exchange program through their service center.
I would guess the cost will be between $50-$150 and you might remove the back panel of the set and look for a smaller board with larger-than-average parts on it and is related to the AC cord coming in.
It should be fairly easy to remove and replace as these are often outsourced and just plugged into the rest of the set with dissimilar plugs making it simple to install and reinstall.
1. the infrared receiver may be defective and may need replacement. This will require service from a qualified tech to replace. 2. or you may have a dead remote. check the batteries also in the remote.
