Re: tv switches on, on its own
I do not know how old your tv is, but I can tell you that if it is more than a couple of years old, the back cover needs to be taken off and blown out with clean compressed air. If your tv has quiet cooling fans on the back, they are notorious in all plasmas and lcds 32" and above for attracting dust and lint from the ambient air. This along with moisture will cause the dust, lint and moisture to settle on critical components that cause tiny static discharges between components that can produce what you described. Another thing is and this is from my own experience is that even the tiniest pest like a roach or a spider, like I said depending on the age of the tv, can cause similar problems my traversing across the components. I had an RCA that would turn on by itself and change channels by itself. All in all the one thing you can do yourself is clean it out of all dust and debri. Good luck and God bless you. Robert

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 cant,the tv will always come on the tv channel. you can turn the item off that is plugged into the hdmi port then back on and it will take over the tv channel and switch to hdmi. so on a night turn off the item plugged into the hdmi port and on a morning after your tv has turned on then turn on the hdmi item and the tv will switch over itself
Hello Mary and thank you for choosing FixYa today for your online technical support needs.
When you say the TV is FUZZY, do you mean that there is no picture there at all?
It is possible that your grandaughter may have changed the VIDEO INPUT MODE SELECTOR on the TV by accident when she tried to turn it on with the controls on the TV itself.
Most TVs have a button right on the front of the set itself labelled INPUT which allows you to switch between the various input modes. That button should be located right beside the POWER, CHANNEL, and VOLUME buttons on the TV's front panel.
You may simply need to press the INPUT button and select the proper INPUT SOURCE for your Comcast cable box.
The proper INPUT MODE for your particular setup will depend on how your Comcast cable box is connected to your TV. If your cable box is plugged into your TV with an HDMI cable, then make sure your TV INPUT MODE is set to HDMI.
I hope this helps out, and please feel free to comment back to this page with any additional questions or concerns and I will respond back.
If you do need additional help, please be sure to include the exact model number of your TV and of your Comcast cable box as well as how the two are connected.

the problem is with the control panel of your tv...make sure your remote doesnt have any part in this...just remove and the batteries and check if the channels still are changing.....see if the onboard switch for channel changing is stuck ?..if stuck u can use homemade tools to pull it back......if your tv is within your gurantee period...just giv a call to customer care....if not u can take it to a local repair shop...there is nothin that u can urself do to make it right ...sorry....for further info contact at
The controller eprom is in a fatal error and cannot be repaired. The pink indicates that a channel in the LVDS interface is gone and that cannot be repaired. This most likely is caused by a failure in the LCD module itself which then shorted out the driver on the main board. If your unit is under warranty, take it in as the LCD panel itself should be covered.
to reset: Info>Menu>Mute>Power Button
make sure tv is off to start with! messing around in here could void your warranty..it resets the tv to manufactures settings.
