Philips TV HDMI CEC EasyLink tries to control Cable set top box

I have reprogrammed the remote for my particular TV (Philips LCD 42PFL7403D/F7) and also programmed a Universal remote - my problem is still not solved - the remote does not control the set top box when the TV is on.

I think it must be something to do with the Philips TV having HDMI CEC? The TV seems to try to control the set top box.

If the TV is off the FIOS remote will control the Verizon HD Set Top Box just fine. But when the Philips LCD HDTV is switched on, the FIOS remote will not control the Verizon HD Set Top Box anymore. The FIOS remote will control the Philips HDTV just fine.
Has anyone got a solution?

    The number you gave would not talk to me because I'm not in PA. The Virginia number just refers me back to the documentation for the remote.

    I believe this is not a programming issue with the remote anyway because as I said the remote does control the TV - but it does not control the set top box when the TV is switched on - that is the problem.

    I have the same problem with the same model of the tv (42PFL7403D),except when the tv is on i can't seem to control my comcast box, or myjvc dvd player. I do see my tv's small led on the lower right handcorner blink when i try to use the comcast remote.

    How do I stop the TV from interfering? Or is there a better tv code to program the remote so it wont interfere?

    Same phillips tv, but with a samsung micro home theater system.  With the home theater/dvd player plugged into the tv via hdmi, stuff goes screwy.  If i turn on the home theater system and it was previously set to dvd/cd mode, the tv automatically turns on and jumps to the hdmi1 input.  If i want to listen to the fm radio on the home theater system, I have to switch the function on the hts and at the same time turn the tv off or else it will all switch back to dvd mode.  I have two auxiliary inputs on the hts but I can't use them because as long as the tv is even plugged in (not even on!) via hdmi, everything jumps back to dvd mode...VERY VERY frustrating.  I would be satisfied if the Phillips tv allowed to turn off hdmi cec, but it won't.

I finally found a fix to this! YAY. I thought I might have to return the TV. I have the Phillips 42PFL5603D, but should work for other models.

On the TV press menu picture settings---picture---dynamic contrast (turn off) AND active control, turn off
If you have Comcast Moto box: on the Cable box go menu--->setup--->cablebox set up---RF BYbass set to ON
If you have a non-Comcast Moto Box, I'm sure there is an RF bypass setting in the menu. You'll just have to look for it. Another fix was close saying to only turn of the active control, but it took all 3 of these for it to work consistently. The latter let it work for all of 30 seconds.

It seems its the RF freq. But the verizon fios hd/dvr set top box only has options to change the RF channel from 3 to 4. I did this, and turned active control off. It seems to be working for now... We also called verizon a few times and they reset the box and we described all our problems. It usually works ok for a little while after so we'll see. But the problem seems to still exist, the problem being unreliable remote communication.

Also* Some people have said the stb only works with the tv off, this may be true but I found that just pressing "menu" on the TV remote will allow the stb to read the verizon remote. So sometimes you can do this "dance" where you hold both remotes and press tv-menu every time you need to press a key on the other remote. Better than turning the tv off every time.

Check out solution #2 from pghcraig. I would have kissed him if I could!! We had Verizon out 3 times, the remote would work, then stop. We tried 3 different boxes, they could NOT solve the problem. The remote worked fine when the tv was off. I found Craig's solution online when the last tech gave up, and we turned of the Active Control and Dynamic Picture Control - success!! The tech took the answer with him. THANK YOU CRAIG!!

    It is a programming issue you either need the remote programmed to a differnt setting or you need them to swap out the box from verizon your signials are just interferring with eachother but it is a easy fix....or should i say a cheap fix



    Ps Just dont tell them your not from PA just tell them you need a few remote codes for your tv...

    steve albertson Jan 14, 2009

    You can turn the cec feature off from your tv also if youy need to but you told me the problem was the remote will work the tv but not when the box is on that means the infrared signial is crossed thats why there is differnt codes incase this happens i dont know why you would give me a innappropriate rating just because your not understanding what im saying to you...

I have a  Phiilips 42PFL7403D-F7 42” LCD TV and had the same problem with my Comcast Motorola remote - it didn't work when the TV was on. Trun the TV off, and it works just fine. Philips told me to turn of the active sensor (under picture controls) and it everything works. The Philips was interfering with the Comcast remote.

SOURCE: Trying to connect PC to Philips LCD HDTV

While the tv is on the right input, and the computer is running, try unhooking the cable and hooking it back in. That's the only way I can get my Philips to detect the HDMI signal from my pc. I haven't found a fix for it though.

SOURCE: Philips 52'' LCD HDTV. Has PC Input Issue.

Hello Terry,

I have the exact same problem that you described. I have tried 3 different HDMI cables. I connected my laptop to another LCD TV and didn't have the issue with that TV. It seems to be something related to the Phillips TV but I am still figuring this out.

Have you solved the issue with the HDMI to HDMI cable from the PC to the TV? My TV is the exact same as yours.

Why does it turn on, then off?

"HDMI-CEC", short for HDMI Consumer Electronics Control, is an HDMI feature many TVs and peripherals have.

If the TV is connected to an HDMI or a programmed remote is being used on the cable box the TV may be getting a second command via the HDMI cable.(CEC) Suggest disconnecting the HDMI cable and manually turning on the TV and see if it will remain on with just a blue screen, Try changing the input to antenna-DVD etc and see if the TV remains on.

You may need to check the settings in the cable box or DVD to change the auto control(CEC) feature. Or if you prefer controlling the TV via the cable box remote then you would not use the TV remote for turning on and off.

This can get very confusing because the TV and the DVD or the TV and the cable box will interact between each other. The problem can be more confusing if the components are not exactly compatible with the CEC. Also many remotes have the additional feature of controlling other components in your AV setup. Many times the operation is alternate action. So each cycle of the remote the TV changes state from on to off. If the two components are out of sync than one is on and the other is off. In that case not using the master on off of the remote but using the individual component setting allows for the two to be sync again. (both off or both on)

How can i unlick philips hotel tv 32hfl5662l/f7

How to switch your hotel Phillips 32HFL5662L/f7 to HDMI if you need to.
(I'm stuck in St Johns, Newfoundland, miles from the downtown....I must be bored)
1. You will need a serial DB9 M-F cable, your PC with a serial port and a terminal program like Hyper Terminal or Putty
2. Set your baud rate to 115200, n,8,1
3. Unplug the AC adaptor connecting the little smart box on the back of the TV. The TV may plug into this adaptor as well, so just plug the TV back into the wall. If you do not, the LCD TV will try to switch back to cable after you select HDMI.
4. Power on the LCD TV and you should see data on the PC screen in readable text.
5. You must send a carriage return after each command <cr> (the enter key on your PC)
6. Use only small letters (no caps)
i - info
u,d,l,r - Up, Down, Left, Right
p - PIP window toggle
To set to HDMI use the following sequence:
i <cr> (menu)
d <cr> (down)
d <cr> (down)
r <r> (right)
then use 'd' and 'r' to select the right input

When i go to hook up a hdmi cable to my philips flat screen it wont recognize that i have a hdmi plugged into it. so what could that be the tv? the hdmi works with my other tv though

This model has 4 HDMI inputs, do you get same problem in each HDMI input?
Did you checked HDMI input with any other video source like dvd player or PS3 etc instead of cable box?
Below are few helpful tips to connect HDMI input..
1. Ensure that your HDMI cable is certified.
2. Press SOURCE on the remote control to switch to another source and then switch back to the HDMI source.
3. Reset the accessory device and the TV.
• Turn on the TV
• Select the HDMI channel
• Turn on the accessory device
4. While the TV and the accessory device are powered on, unplug either end of the HDMI cable and then reinsert the cable.
Try above options and if tv still does not show picture of any video source through HDMI then it seems problem of HDMI processor located on main board, visual check is needed by qualified tech or call Philips if tv is under warranty.
Hope these info will help you.

What is easylink connection? Wireless? HDMI?

The Easylink is Philips name for HDMI CEC which allows multiple HDMI devices to control each other with one remote.

As for the looks like there is only one audio out and it's in the form of coaxial cable which isn't very helpful.

What I would suggest is that you tap the audio coming from the input. So I'm assuming your TV is connected to a cable/dish box. Use the audio out from that to power your headphones or external speakers. This will likely mean you can't use the HDMI or will need a splitter, but at least it will solve your issue.

HD Video Recorder - CEC connection with HDTV

My first question would be, Is your Panasonic HD recorder CEC compliant? CEC means Consumer Electronics Control. That simply allows for the consumer to have better control over their Home Theater set up through the connection of you HDMI cable from their remote control without programing the remote control for every single device that is connected. If your recorder is CEC compliant the television should have automatically recognize the recorder and control you recorder via remote control (I am assuming that your recorder is an HD Camcorder, since your description was very vague). Once you connect your HD camcorder to your panasonic tv the tv should have turned on switching to the correct input and the same for any other CEC comliant devices. If your Panasonic HD recorder is not CEC compliant the you would have to start viewing your recorder the old fashion way, by using the recorder remote control or if your Toshiba remote is universal punch those codes in so that you can control your devices that way. If that don't work, try a different HDMI input and select the input and make sure your recorder is set to output on you tv. Hope this helps.....before I forget, check out this site to learn more about Consumer Electronics Control (CEC)
