I have a 42" flat screen. Only two years old.. It just went black during a movie and won't do anything. When I unplug it and plug it back into the wall the light just stays blue... No access, picture, nor...

Try leaving it unplugged overnight; it may have an IC locked up.
If that doesn't work, it is likely a power supply problem, these are all too frequent with our sets.
There are at least two supplies in your set; one of them (a low-voltage section or board) stays on continuously so the set can respond to commands from the remote. The other is turned on when you power the set up via remote or button push.
If the set isn't responding to either remote or local set controls, it is likely that the main power supply has failed.
Your help request is captioned as a 52" model number but your text says it is 42" so you need to add the correct model number before anyone can help you.

No color, just black and white. Problem arose when synchronizing Pioneer remote for SD533HDTV to a Logitech Harmony remote.

I just wanted to let you know that there is no possible way that this problem was caused by the Harmony remote. When you are learning commands from your original remote to the Harmony, all that happens is that the Harmony remote reads the commands that your original remote is sending. It does not change anything on the original remote.

Hope you are able to fix this. :)

My philips 64p8342 doesn't turn off

It may be due to many reasons. 1.If your remote is not working or it's battery got over: But then not only the power button, but no buttons will work. 2. If your t.v receiver is faulty: Then also it should not obey any commands, not only power on/off command. So most probably, the power button of your remote is damaged. It may be an internal loose connection. It may happen if your remote has fallen down or anything similar. Get it repaired or have your remote replaced.

Forgot code to unlock parental lock. Everytime I watch a p-g or r rated movie it ask for the code.

The only way I know is to reinitialize the set. You do this by pressing Menu on the remote control, the pressing the number buttons 2,2,7,0 in sequence. using the remote, press the adjust button to hi lite INITIAL, then press enter on the remote. this should put it back to out of the box settings and clearing the parental lock code.
If you have kids, I recommend they do not watch you do this.
Good Luck,

When all else fails try this.
With the tv on, with your remote punch in this series of commands--menu , 2, 4, 7, 0 the tv will show the option menu.
Make sure "initialize" is highlighted. if it is press "enter" on the remote. Wait a few seconds. The tv will default to customer factory settings, in other words the way the tv was when it came out of the box. DO NOT HIGHLIGHT ANYTHING ELSE IN THE OPTION MENU !!!!!!!!!

Good luck

Tv turns on manually, but auto flips through channels and you can't use remote

Found this in another forum ( and it fixed my remote problem:

"'s possible that one of the front panel buttons is "stuck" or shorted, and this could cause the TV to ignore commands from the front panel or remote. But this should also cause the Power command to be ignored, too. You might try pulling off the front panel and disconnecting the front panel buttons and then see if the remote works."
