There is something wrong with the voltages out [low voltages] from the main power regulator board. Check it. If you wish to get more details, check this site. http://electronicshelponline.blogspot.com/

I had this problem, but saw other places that it was a cheesy capacitor on the power supply circuit board causing this. I opened it up and took the power supply board out and it was obvious which capacitor was bad...top was bulging and had black stuff on it. It was rated 2200 uF @ 25V...got a new one @ Radio Shack that was 2200 uF @ 35v. Soldered it in (I stink @ soldering, but gave it a shot and it was EZ). Watching the first weekend of college football w/o waiting on a flashing green light for up to an hour so the TV would start! I'm going to try to find the other websites that directed me to this to say THANK YOU...BTW my brother used to have fits with several Magnovox TV's and thier power supplies back in the old tube style TV days. I thought I didn't need to worry about this with an HD flatscreen, but was wrong. I will think twice before buying a Phillips/Magnavox/Funai/whatever else they are again. They have a long list of complaints and I believe a class action lawsuit to refer to about this problem. They should have stepped up and done something!

Set your volt meter to the diode check and measure across the white fuse [power off and unplugged],Shuld read zero. Then the fuse is good, an open fuse will have no reading. If you replaced the caps....be sure the voltage is the same or greater. The Mfs must be the same...and most importantly be sure they are 105dgrees. In some cases they could be 125 degrees. If you replaced them with 85 degrees you will definitly not get a good start up. And always be sure you check the polarity on the caps to the board. The board should show a plus or minus. The long leg on a new cap is always positive. Locations for the caps I believe are2074 which is 25volt 2200Mf and cap 2081 is 35volt 1200Mf and a third cap 2066 at 16volt 10Mf. Be very careful with cap 2066 as the trace on the board can be damaged when you unsolder this! Good Luck!

You can power scan for the code.
Turn ON the electronic device you want to program the remote to control.
Press the Mode button( sat,tv,dvd,aux) on the remote until the appropriate mode light is flashing.
Press the Power button. The mode light will stop flashing and stay lit.
Press the Up or Down arrow button to set the remote to the next code. The Down arrow button scans backward and the Up arrow button scans forward.
When the correct code is reached, the device (whether a TV, VCR, or other) will turn off.
Press the pound key button to store the code in the remote control memory. If the code is valid for your remote, the mode light will blink 3 times.
Turn the device back ON by pressing the Power button.
Press sat mode key once you power back on the tv to be able to operate the receiver box.
Try some other functions to make sure you have the correct code. Occasionally the Power button may work when others do not.
If the other buttons work you are finished.
.
If the other buttons do not work, repeat the previous steps. The scan will resume from the last code stored.
The mode light will flash rapidly when the scan has returned to the starting point and all codes have been tested for that mode. The remote control may not control some device models.

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!

The tv was working fine until this morning, then the picture went out but the sound is still working.
TV is only 3 years old, no real electrical problems
