I turned on the tv today and the menu and source pictures change on their own like every 2 seconds. The source goes from cable, to hdmi to s-video very sporatically like the menu or source button is stuck or something. I took the batteries out of the remote and it still does it. I try to push the source button and menu button on the side of the t.v. and it still does it.
THe only thing that partly stops the flickering is i hold down the menu button on the side of the tv.
It's interesting I unplugged everything and it sat for a few days. I plugged everything back in and it works like normal again. It's been fine for about 4 or 5 days now. I will try what you suggested if it messes up again. But just to be clear, did you mean to try to press the buttons on the TV repeatedly? or the remote buttons?
Litigation- O.k if your tv is cycling through the menu ect. it sounds like you have a bad tact switch.Try pressing the contol panel buttons repeatedly,most of the time the remote is used so the tact switches go bad. Try this out ,it may help to clean the contacts. Just make sure you press them alot,it helps most of the time,if not you may wind up in the repair shop.Have fun and let me know. cooltek Mar,4/08

Hi Geoff, I hope I can help you with this. If you are using an accessory device (DVD, DVR) check cables to see that they are secure and if device has audio out option that it is set correctly. Also check to see that Video and Audio cables are connected to matching inputs on your set.
If you are using DVI to HDMI you will need to use a separate digital audio cable. DVI cables do not carry audio signal. After attaching the audio cable if you still do not hear sound you may need to set Digital Audio In. To do so:
Press Menu Button on remote.
Press the cursor ring down to highlight SETUP.
Press the cursor ring left to enter SETUP menu.
Press the cursor ring down to highlight SOURCE.
Press the cursor ring left to enter SOURCE menu.
Press the cursor ring down to highlight DIGITAL AUDIO IN.
Press the cursor ring down to select the source you want to associate Digital Audio with. HDMI 1 or HDMI 2 in this case. You might need a software update also.
The latest software solves the issues below:
TV (Plasma 42" and 50") will not turn ON/shut off itself and Red LED blinks 4- times. Recover if main switch on/off.
37" LCD full white screen appear when upgrade software.
Some channels not available after turn ON.
Delta volume changes, not remembered.
Preferred channel changes, not remembered.
Green or yellow static (sometime snowy) on HDMI picture.
Picture and sound loss for 5 to 10 sec (green LED is still ON) and back to normal.
Audio loss in all inputs and can be recovered when main switch ON and OFF.
TV set turn ON by itself/ green LED light up and goes off when set is ON.
Intermittent audio loss in NTSC RF channel.
Crack sound with high input signal.
Include the possibility to download the rating table (RRT5 capability) for digital programs.
No video/ no picture with sound.
Intermittent On-Screen Menu pop up by itself and can be removed by pressing the 'MENU' button.
Channel information display too long.
Improvement on scramble channel.
How to check the current software version on my TV set?
Press 'MENU' button on remote control to display the on-screen menu.
Select TV MENU and press the cursor right.
Select INSTALLATION and press the cursor right.
Select SOFTWARE UPGRADE and press cursor right.
Select CURRENT SOFTWARE INFO to display the current software version on your TV set.
If the TV software version is lower than the version posted on the website means your TV set needs to be upgraded.
Follow the instruction in the user manual or Firmware Upgrade Readme file on how to upgrade your software.
Where can I find the latest software for my TV set?
The Firmware Upgrade Software and Readme File documents can be found on the Philips support website. Refer to the SOFTWARE section.

You need to describe what is the source. Sometimes the input selected on the TV needs to be changed. Try pressing a video or source button on the TV itself to see if you're looking at the right input source. Sometimes you will have five or more inputs like HDMI and Composite. Look at where you connected the input signal and see what it's called, then look for that input on a menu of some sort.
Tv have a shorted IC that control the manual control board side of the tv itself or the manual control board itself it is dead.Tries websites like Shopjimmy.com,Ebay.com to buy a refurbish manual control board.Replace the manual tv control board first to test it out.If u still have the same result the IC that control the board itself is dead,now must take to the shop for repair.

I have the same issue. TV is ~ 2 yrs old. Ruled-out cable-box & HDMI cables (green present in menu mode with no cables attached).
Screen turns mostly green, with a crappy picture. After a few days, a normal picture just appeared. Today I powered-on, the green screen stuff came up, then a minute later a good picture for about 20 minutes, back to green-stuff for 10 seconds, then good picture.
